Looks like that would do it also it would not take much to spend alot of money with them,really cool stuff.Thanks

I am seeing about 300 mah X2 (300 per battery) for a 15 minute flight, whereby I perform exactly 15 snaps. The peak amp draw is between 3.5 and 5.6 amps when I do the snaps.

Funny this would come up. I’m getting parts together for a new plane and have a magnetic switch rated for 15A/30A burst. It’s a 70CC size plane. Anyone know the approximate draw of 5 high torque servos under aggressive flying?

that switch will be fine. if you fly spektrum you can make life a bit easier by using a powersafe receiver.
