Yes, supercapacitors are much weaker than LIPO. But a minute is enough for a free flight. Me and my friends charge supercapacitors to 4.2 volts from 1 LIPO. SCAP is tolerate this overload.
The plane in the picture has experienced a lot of bad landings. At the same time, the propeller wound the grass or jammed. And this did not lead to damage to the engine or capacitor.

I hav some planeswith supercaps....but some caps aren't as powerful as a batt....and the cheap ones from China seem to be better than those from mouser.com
I want to try a E20, as soon as I can get a motor!

what do you know about supercapacitors?
They don't require a timer. They are easier to use for free flight than rubber or CO2

I have the ''need' to make a small FF in-between bigger birds. Here's a current build....plans just printed off HPA plans page, and I redesign parts for lightness. This model is for flying, electric on a 70mah batt, with home made timer.





Johnathan has helped me build these timers....

The resister will be changed on this one...it's way to short of decay!
