I'm trying to figure this out. The instruction manual says you need a 4 channel. I'm thinking about getting a 6 channel futaba 2.4ghz radio (also comes with the servos S3114 that I think will work well with the Cularis). I'd rather not spend the money for the Futaba 7C. Would the 6 Channel be good enough for this aircraft? I'm mostly a sailplane/parkflyer type of person.

This should work fine with the Futaba 6EX 2.4 radio

Be sure to get an appropriate battery pack and other needed equipment.

WOW, thank you for the quick reply! Speaking of power packs I'm going to get this:

But am wondering about battery size as per this chart:

Thinking of this battery:

for its wieght and 18C. Could this motor and speed controler handle a 20C?

I'm not really an electric flight guy so I'd just be guessing. Someone will come along and help with that issue. BUT, good radio.
