Did a flight test on the soon to be released Stinger Quad Copter. However, I failed to properly secure a set screw, losing a motor on a Quad copter is a problem. After airing it off (landed in a puddle) I’ll wait for it to dry completly and remount the motor. More flying Wednesday.
[display_podcast] Welcome to the Radical RC Workbench, Radicalcast. Today the topic is 12v power supplies for the flying field. Dave will cover how many amps your power supply needs to be to drive your chargers and how to get the most life out of your 12v wet lead acid batteries.
Note, this is my first cast, just warming up and learning this new skill, they’ll get better I promise. 😉
Wow! Thank you so much for being a GREAT online business! Companies like yours make me want to spend my money more freely because I have confidence that they will do right by their customers. I look forward to doing business again very soon.”

“Hi Dave, I just wanted to thank you for the help you’ve given me this week. It’s nice to be out flying again with the right equipment.
I also wanted to pass along kudos for your employee “Chris” who took good care of me when you were off to a show. He answered my questions and filled my order in a hurry (using some very good creativity I might add) to get me up and flying within 2 days. I got to fly all weekend due to Chris’ hustle. This is the stuff that will make me continue to buy from you guys.
Thanks,
Dave Kelly”

“Hey Dave, Just wanted to send off a note to praise Chris. My last order was incorrect, and all it took was a call and Chris was making it right.
Thanks for the great service.

“Dear Dave, Just a follow up to our meeting at the recent NEAT Fair. By the way the January 2002 RC Modeler will have the first published report of our NEAT Fair. Dates have already been set for next year; they are Sept. 13, 14 & 15, 2002. Hope to see you there again.
My reason for contacting you, at the Fair I purchased an 8 cell 720 MAH Sanyo NiMH battery pack from you. I just used this new pack the other day with excellent results. In my application I’m drawing 5.3 amps (at the start) on a Speed-300 motor geared 5/1. First flight was almost ten minutes with the motor running at full throttle the entire time. After landing the battery was only mildly warm. I have been fast recharging this pack at the field at 1.4 amps which takes an average of 30 minutes to reach a full charge. Do you feel the 5.3 amps is OK for these cells? I’m very impressed with the performance.

Yes, they can take constant drains up to abut 6.5 amp range very well.”

Re: (RRC-300 packs)
“Dave, Hi, I picked up a 7-cell pack of 300 mAh NiMHs from you at the SWAC, back in May. You asked me to let you know how they worked out.
THEY ARE FABULOUS !!!
Light weight, powerful, and getting better with every cycle. I’m currently using them in a GWS Tiger Moth powered by a GWS DX-A and
GWS 9 X 7 prop. Perfect combination!
I’ll be ordering some more packs soon.
Thanks a lot.
Happy flying,
Gary”

Re: (RRC-300 packs)
“Thanks Dave for the lite stick packs. They are great! My Pico Stick never had this much power. We can do inside loops with this guy now! I haven’t timed em’ yet, but I bet I get 15 minutes out of these guys.
Thanks again,
Alan Black”
