Default RE: YS-170CDI Flight Report

Keith,

Thanks for your note. Weight is not a problem for me since I'm not flying pattern - just a 73" QQ Yak (not a pattern flyer - yet!). I'm thinking of putting in a 4500 MAH JR battery pack, which should provide enough backup for all servos as well as the ignition.

Do you use a Switch between the Receiver (9 channel) and the Ignition. I am presuming so. Will a normal JR switch do?

And how about a 6V regulator: is that too much voltage for the ignition? i.e. should one definitely use 5.7V or some regulator lower than 6V? I would hate to mess up the Ignition!

Thanks!

Hi Atul,

The Ignition unit draws 0.32A at 7800 rpm. For a 10 minute flight at full power this means you'll use around 50 mAh, but obviously you'll never fly at full power for that length of time. The battery size will then depend on your setup and tank size.

Bets wishes

Keith
