WANTED: Mini Ultra Stick Wing

John in the shop has a good fuse and could use a wing. Even a broken wing or 1/2 wing would be welcome. Please contact me if you have one available.

First Manned Multicopter Takes Flight!

Check it out, see if you can figure out the controller logic to make this safe as possible. A step beyon fly-by-wire for certain. Maybe with some aluminum, rivits and 4 quad boards you too could be seated above a blender. 😉

2.4GHz: Is it all it’s cracked up to be?

Artical at Model Airplane News written by: Dave Horvath

This is an important artical explaining some of the reasons why 2.4ghz has issues. People can be counted on to always presume that newer is better. I was very late to start using 2.4ghz due to reliability issues. With about 1/3 of our hobby being replaced by newbies every year, it makes perfect sense that not many lifers are left that remember what standards of reliability we had acheived with 72mhz. Dave Horvaths artical is important reading to gain a broader understanding of how things work.

Doc Brown Power Supplies Checked For Possible HAM Usage

I’ve had several inquirys wondering if these power supplies can be used for Ham purposes. A local Ham checked one out and writes:

Dave …
I’ve used this with a Yaesu FT-817 (5 watt, around 2 amp), scanned across the bands, and found several places where there are “birdies” or RF that can interfere. It seems to be on the power line, since I had no antenna attached at the time.
1.805 MHz, 1.784, 1.685, etc. These likely come from the switching mode, since the signal disappears when the power supply is unplugged. I would suggest that HF ( from 1.8 MHz to around 30 MHz) may be usable on some bands, but not all. At VHF and UHF frequencies it is well filtered enough to use, that is at 140 MHz and 430 MHz. With its current level it could run a 100 watt repeater at VHF nicely.
Of course, this isn’t at the same level evaluation as someone at the ARRL or FCC labs, since I have not measured the actual level of signal involved. I can not see anything on the Tektronics oscilloscope, but it only goes to 2 mV/cm. A signal at that level would be rather loud.

Ampeer Newsletter and EFO Website

Edited and published by Ken Meyers, the Ampeer is probably the longest running electric flight newsletter on the planet. Lots of good information. One of the few things I subsribe to. It’s free and is published once a month. This months issue covers the Mid-Am electric fly in from which we just returned. You can see a photo of a very nice Radical RC Wright Stick that flew there and supurb shot of my Quad Copter in flight. Check it out and be sure to sign up for the newsletter. The EFO website where Ken keeps all his handy help pages and articals is linked at the bottom of this post.

The man who thinks he can.

If you think you are beaten, you are;
If you think you dare not, you don’t.
If you’d like to win, but think you can’t
It’s almost a cinch that you won’t
If you think you’ll lose, you’re lost,
For out in the world we find
Success begins with a fellow’s will;
It’s all in the state of mind.
If you think you’re outclassed, you are.
You’ve got to think high to rise.
You’ve got to be sure of yourself before
You can ever win a prize.
Life’s battles don’t always go
To the stronger or faster man;
But sooner or later the man who wins
Is the one who thinks he can.
