Walkera F-22 Jet

Looking for the CG of this old jet. Anyone got one?

Got several of them, a couple new in box and my regular flyer...... I'll stuff a battery in my regular flyer and get you the CG.

You've going to discover some thrust line issues. If you are still using fixed tails, you need huge control throws on the ailevators. You'll need a fair amount of up reflex when you launch, the model will fly failry scale and majestic. If you chop power, it noses up and will stall. Going to wide open pushes the nose back down (which might not be good if runningout of air space). I'm going to suggest modifying it for regular elevators to aid in pitch control. It's not mandatory, but you'll be more pleased with pitch control.

Would you reccommend just building it with tailerons then and ditching the aileron control?

NO..... Keep the wing surfaces active. Tailerons by themselves won't offer enough roll authority.

I pulled the plane out, using a 3s 3300 mAh lipo, stock fans with Walkera 380m brushless motors, twin 30A escs. My balance point is at the rear edge of the oval grip holes under the fuse.

Discontinued long ago. I have two of them tucked away for a rainy day.
