Good to be back!
Was lost for awhile on another site and couldn't find the Gee Bee thread---and thats confusion from life saving legal drugs!
I dont even want to know what confusion of voluntary drug use is like!

I am still trying to make up my mind on engine choice.

I would like to use my biggest gas engine(46cc) on the Mulligan and the smaller 30 or 35cc on the Gee Bee.

The biggest fear I have of going with big gas engine is that the wing and elevator will give up in a not so elegant manner.

The bigger engine will help balance after cockpit details are added and am considering placing elevator and rudder servo in rear of fuse.
Servo location will be last to item to solve.
Possibly hide the servos under cockpit floor?

Glad to see interest in 30s race planes!
What I like is for 1/4 scale size is one can have almost any size airplane span/power and stay at same scale!
Makes for better looking hanger!

Next on my list of build projects will be Keith Ryder's R-4 in 1/4 scale with K&B 7.5 duct fan engine.
Should be fast!
Looking for good 3 view of R-4--any ideas?
