Latest Electronics Update
03/16/2020 at 22:42 • 0 commentsI think I have the power issue figured out and a few other problems that crept in.
Heat: If the motor runs at 5v, it does get hot. I added a 6Amp dropping diode in series with the 5V so now it runs on 4.3V which is about equivalent to a charged 1S battery.
I also discovered some of the motors I ordered were the same size physically but didnt' have any power at 5v. Those needed 7.4v (2S battery size) so if you order those motors, you can use this supply and just dial it to run all the electronics with 7.4Vdc. Use Vin on the arduino and it will step that down to 5V.
It's not UL rated :( so don't use this one, but find something similar....

Coast Guard Rescue Trailer :)
03/16/2020 at 04:58 • 0 commentsI have the CG VB flying nicely now. I had to add an ESC (thing RC airplane) and a diode to drop the voltage from 5 to 4.3V and it is flying very nicely now..... I will post schematics soon.

My 9 year old son did that trailer from our iPad :)
He is just loving any toy I 3D print from an old 70's design!

Power Issues
02/29/2020 at 20:58 • 0 commentsSo the little RC motors are drawing more current than I expected. I have a 5Amp 5Volt supply and now the speed controller IC is shutting down during flight. I have some RC speed controllers on order and will be installing those and then I'll post the code to run the Vertibird.

The Ship is done and once the powe issue is solved, I will post a video.
