Celina Ohio Largely Bans All Flying Toys

What follows is my letter to the editor of the Daily Standard sent 11/12/2015

Editorial content regarding the ban and profiteering on technology toys in Celina.

Merry Christmas to the parents of children with dreams of the worlds latest technology boom. Celina counsel members Larmore, Eric Clausen, Fred LeJeune and Fleck wagging their smoking sulfurous finger have decreed your children have no right to play with their flying Christmas gifts on their parents own property. These children and their parents must pay the city in order to operate a toy airplane or helicopter on their own property, in the park or on private property. The supposed land owner can’t grant permission or use their land peacefully to their own pleasure. But wait! Permission is for sale by the Celina City Counsel! Flying toys are no longer on the 3×5 card of approved activities within the city limits.

These council members dream of a right to collect a living, to charge a toll for the use of “their” air. You pay them if you wish to use your property (you own the parks as well as your home) or risk fines (theft) and arrest if you persist in pursuing happiness peaceably and safely. May the citizens of Celina find the courage to join with me in ridicule of these pursed lip technology averse all-knowing overlords.

City leaders criminalize the peaceful to aggrandize themselves while enriching their office. Another victim-less crime to add to the list of enforcement opportunities. What a lesson the Celina Police department can teach the youth of Celina about the importance of respecting officers and the law by imposing this ridicules Objection to Liberty! Any Officer, Chief or Sheriff who will not refute and refuse to enforce this Objection to Liberty should be tossed out on their ear. Join with me by fully and clearly rejecting these pitiful representatives of Celina. In your name citizen, they punish the innocent peaceful users of toys. Can this be the most pressing concern within the city limits? Shame on the leaders of Celina. What next? Shall we walk technology back to the wagon wheel? A book burning? Do we outlaw Frisbee’s and footballs? Permits for cell phones? Larmore, Eric Clausen, Fred LeJeune and Fleck, SHAME ON YOU!

Look what Mark Stephens of Virginia sent me:

mark stephens

Check out Mark’s use of our modification parts to create his own custom FPV platform. Single motor tractor with the camera out front.

After crashing with pusher config, I cut off the top of pusher mount to just use as perch. I’ve got three diff size battery trays, axle mounts, vertical stabilizer mount, boom mount, and a few mounting thingies on the bottom in case I need them later. I flew this config today and it flew wonderfully. It felt like RC car on the ground, it tracked wonderfully with four wheels. Anyway, thanks for talking to me last week when I called. I took your advice and put the camera up front. I’m very pleased. God bless and thanks again!

Thank You,
Mark Stephens

The AMA goes to 12 Expiration Dates Each Year? Seriously?

Submitted to Dave Mathewson, AMA Executive Director. Concerning new membership rules which will have memberships expiring every month and not just once each year. 06/23/2015


Our club like many has an agreement with the field owners to make certain every user is an insured AMA member in good standing. There are something like 200 to 300 people issued a key to our facility in each year when and only when they show a valid AMA membership card. We change this lock once each year necessitating a presentation of a new AMA card to get the new key. Thereby we assure each members current valid AMA status is eyeball verified once per year.

With memberships expiring every month, how are we to keep track of those wandering in and out now? Are we to post an officer at the field during open hours to check expiration dates on cards and revoke keys? If the club secretary or VP or Pres is made responsible to make these collector calls for the AMA, how are we ever to get volunteers for those positions? What a distasteful horror of a responsibility. The discomfort and embarrassment at confronting people and being confronted over your bill paying capacity is quite an undesirable position to be in. I’m quite certain nobody ever thought they’d be asked to such things when they joined the AMA or their local club. What they were thinking about was having fun!

What if ones membership or grace period expires a day or two after registering for an event?

The officers of our club are probably not aware of this complication as of yet. I think they are going to be slowly discovering the ugly responsibility being thrust upon them all across the country.

I can certainly understand the AMA’s need for a smoother work flow and a more regular cash flow. I do not see how our club can offer assurance to our field owner that we are able to juggle this hot potato. Whats worse, many clubs will decide to go along and get along and not complain. They’ll just continue their regular programs and begin to rely on “the honor system”. Many pilots will slip into an uninsured status which will be left un-managed. Are we seriously expecting our officers to drive to the deadbeats home and demand return of their key? Are we to change the lock and reissue keys on a monthly basis? What color is a valid card this month? Next month? When accidents occur with members who have unpaid expired memberships, they won’t be covered (rightfully so) and those people experiencing loses will be heading to the property owners to be made whole again ‘because of the AMA’. Will fields be slipping way because of this well intentioned program?

Membership periods need to have a predicable and simple pattern if the executive committee wishes to maintain our member clubs capacity to accurately assure financial responsibility compliance.

Why can’t the AMA simply prorate memberships so new member entering in the middle of summer are not paying a full year fee for a 1/2 year membership? Thereby assure they end up with a renewal date that is commiserate with the AMA’s interest in clubs successfully maintaining insured access to flying sites?

If cash flow is an issue, why not offer a goodie, micro discount, pat on the back or….. for the privilege of charging one’s on file card 6 months in advance in 1/2 year increments? There has to be some other answer which does not require the complete revamping of security procedures and additional management complexity at every flying site in America.

What we can’t lose track of is the typical AMA club officer works on meeting day and the events he volunteers at during the summer. These are hard working people who have essentially volunteered for some extra responsibilities when they are “going to be there” anyway. Running collections for the AMA is not going to be considered a pleasant or manageable responsibility.

I am certain as always the AMA’s intentions and your intentions are in the right place. The unseen consequences of this decision and the impact on stature of the executive committee concern me greatly.

Respectfully submitted,
Dave Thacker
AMA Member

Forming a recent NiMH purchase on the Hitec X4 and other computerized chargers.

Ed writes me about properly forming a recent NiMH purchase.

Hi Dave,

I recently bought one of the FDK Twicell 6.0V 5-cell 2000mah NiMH AA Flat Pack and would like to try it in one of my airplanes . I read all your comments about this battery pack and I have the HiTec Multi-Charger X-4 and not sure what is the best way to charge it. The charger is fairly new in my collection and I am still learning the best way to use it any thoughts?




The best way to do it on most computerized chargers is:

General procedure,

1. Go into setup, make sure the mah limiter and time limiter are both off.

2. Put charger in PB mode, yes for Lead acid.

3. Set charge rate to 100mah, any more will ruin the battery eventually.

4. Set voltage of battery to 8V

5. Start charger.

If it refuses to start, set voltage to 6V and let it run a minute or two, the go back and restart with setting at 8V

“Generally” Eneloop’s (Twicell’s) come to you about 1/2 charged. So, the hole your filling is about 1000mah. (Hole * 1.4) / charge rate in mah = time in hours. 14 hours in this case.

What we are doing with the procedure above is tricking the charger into functioning like a dumb wall wart where it will just plod along indefinitely until we disconnect the battery.

The best practice would be to connect the cells to a dumb charger that charges at 50mah for about 30 to 40 hours and is the ONLY method for which I would ever consider warranting a pack. People try to break in new batteries in peak detection modes all the time which is the cause of my slightly “acidic” warnings against such acts on my website. One issue is there are no makers of chargers like that that I know of in the hobby world today. The last one (Sirius) seems to have become inactive. The best chargers to own for this forming purpose at this time are an ACE DDVC, ACE Digipulse or Sirius Pro-Former. Should you run across one at a swap meet or on Ebay, snap it up.

Customer asks a good prop question with implications…..

Hi Dave,

Quick question about the APC props. I note that for multi-rotor the sizes seem to be with 4.5 pitch. Is there a reason why I should not use say, 9×6 with 9x6R for multi rotor craft?


Hovering props or props that produce best thrust in static air tend to be pitched about 1/2 of diameter or less. As you add more pitch, they can fly faster, but have less bite in static air. They can actually be stalled and have less lifting force until the prop gets to moving forward. This is also why props which are the same otherwise make more noise with lots of pitch. Initially they are stalled or partially stalled. So, if you need more prop than a 9-4 to apply the power to the air you have available in your system, you go to 10-4, not a 9-6. Certainly a 9-7 would be such a bad choice as to be worthless.

All this is considering the model is essentially hovering all the time. Even forward flight isn’t quite as forward as an airplane. Other types of flying and machines can have other considerations that make higher pitch (relative to diameter) correct but this is unlikely in all multi-rotors except maybe a racer.

What we call these props is 1/2 square. Meaning pitch is about 1/2 the diameter. A pattern aircraft or war bird might use a 3/4 square (like a 10-7 or 11-8) or even a square prop (like 12-12) because hovering is not a required and speed is more desirable. These setups are poor on hole shot, but once they get moving they really go.

Bill de Blasio to resign?

It’s only a mater of time in my view. The police are continuing to turn their backs on him. He has earned a complete disgust from those the public value as indispensable protectors. How can this stand? What we are seeing is how effective ostracism can be. And, all the while, traffic tickets are down 90%, the predation of the drug war has been reduced. Officers are under instruction to withhold revenue from arrests and ticketing except where absolutely necessary. This of course begs the question, what the hell where they doing before? The society of NY hasn’t fallen apart. Be aware of the important lessons being demonstrated by accident in New York City. This partial shutdown just like government shutdowns can’t go on for long. It won’t take long for the public to realize how unimportant and dispensable such a huge overbearing government complex is. They will bring this “strike” to an end soon. My prediction is with the resignation of de Blasio.

Why Barrack Obama is making the right move on Cuba

I agree with President Obama on opening up with Cuba. Probably for very different reasons than why he is doing it. You might disagree and point out Che hated and killed black people and you’d be right. You might also point out all the firing squads and mass graves of Castro’s Socialist revolution. You’d be right. Many horrible things have been done in the name of “the greater good”. Whenever I hear the utterance of that term, it is always employed as justification of violence or threats of violence being used against a persons natural Liberty to peaceably make their own choices. It appeals to the worst element in mankind’s capacity to use violence and force to control others for the achievement ones own personal goals and objectives.

While the Castro’s, Che and many of their past and current actions are truly evil, what of the people that live in Cuba? Is our disgust, is the enemy of Liberty the people who are imprisoned by the Castro’s?

As a first principle, I regard all attempts to control and limit voluntary exchange as evil. If the people of Cuba wish to trade with the people of Florida or Texas or France or Alaska or Russia or whomever, why not? How do you or I gain a right to act as a 3rd party controller preventing two willing and peaceful people from trading? Simply stated, our embargo hasn’t kept one steak or lobster off the plates of the Castro’s. They live like kings off the people they farm in the name of the “greater good” regardless of our personal offense. I see no right, effectiveness or kindness in refusing an element of freedom to an oppressed prison population of a Socialist state.

As an aside, if they wish to be free from the slavery of their service to the Castro’s, it can only happen when they have something to be free for. It can only happen if exposure to glimpses of freedom and Liberty grows in them a desire to take care of business. By interacting with them, we can provide that encouragement and example.

No person has a right to control, limit or inhibit voluntary exchange between two other people. If we wish to be free, we must identify and reject those who claim a right to impose their choices on others by force.

Clearly, if you wish not to trade with Cuba or consume Cuban products or offer products to Cuba, I support you in your choice. I wouldn’t dream of using force to make you consume or provide services to anybody anywhere. I ask simply that you to consider conferring the same respect of personal Liberty to everyone.

Spirit of Sam Power System Decoded

I’ve had a number of inquiries for an alternate Spirit of Sam power system. I worked out a system for Phil Pearce. He’s had a chance to do some run time and amp draw tests. Here are his comments thus far.

Phil Pearce Spirit of Sam Afterburner Setup

Phil Pearce Spirit of Sam Afterburner Setup

Good morning Dave. Here are a few picture of the little 5 oz Wren, built for the Spirit Of Sam event at the Society of Antique Modelers events. The rules call for the power battery be a single 160 mah lipo. The task is endurance, using the second best flight time of two flights. The motor you provided is an “Afterburner High Performance Brushless Motor. The number on the info. sheet says: MR-012-030-4000-1.5 I ended up using a GWS 9/7 prop. As the picture shows, the rear lipo is for radio power. The BEC is disabled. My procedure for maximum flight time is to hand launch with full power of about 1.5 amp draw, than establish a slight climb at minimal power of probably about 1 amp. I level out at about 200 feet and only use enough power to maintain altitude while looking for signs of lift. The motor will start slowing down at somewhere between 8 and 10 minutes with no thermal help. I must immediately start a landing approach while the prop is still spinning and plan on landing in about 15 seconds. Unfortunately a folding prop is not allowed. The drag on a stopped motor is dramatic on this small light model. I hope this is what you wanted. Thanks again for you help. Regards, Phil

P.S. If you have any advice on another prop, please advise. PP

Note, the point of this blog post is to record what we did in a way that will last longer than my memory. If you want to do the same thing, all the links are provided. ;-)

Some thoughts that I have based on what I know thus far: An “A” ratio (less reduction) could be considered in order to reduce the pitch or perhaps the disk diameter. That might lead to a 9-4.7 or 9-5 or 8-6 being optimal. I’m tickled by the idea of a 4 or 5″ high rpm setup in order to try and get the model to glide with a stopped prop longer than Phil reports with 9″ props. Not being experienced in the competition, my thoughts might be completely off base here. The higher KV Afterburner motor should be avoided because the higher no-load current. Although it might be more efficient at wide open throttle, the minimum no-load current would kill you in cruise (partial throttle flight). So, the lesson is stick to the 4000kv motor. Anything you can do in this contest to utilize a low non-load current motor would probably be an advantage over most motors with higher no-load currents. The no-load current rating is one of the fixed parameters (motor constants) of every motor. Explaining it fully is beyond the scope of this article.
