Hey James,
Arnold from the West side gang, were you the one that had one of these Cemark MB339's in a van at our Baldwin show??

Anyhow, I'm frogging with one myself and was looking to see if the manufacture CG is where everyone ended up flying with??
If you ever got to fly yours, (I didn't see one fly at Baldwin ;-) let me know how the CG was.........

Thanks,
Arnold

Thanks for the reply Jimmy.
I am coming down in March for Florida Jets, are you still going to be in Florida at that time?

Talk to ya soon,
Arnold

OMG, this a blast from the past. I Purchased one of these when they first came out thru GPA Hobbies in Crofton Md. Ram 500 for power, Fut 9202 servos all around. Maiden flight by Eric Baugher, (RIP). I Remember the smile on his face while was flying. He said it flew like it was on rails. Wings were flexing due to screws working lose. Made a one piece airplane, gluing (epoxy of course), carbon fibre around wing securing slots. No more flex. Dropped in a P80 after bearings went in the Ram due to running the airplane out of fuel twice, (what timer)! The P80 gave it some help going vertical. The P80 is still in it, I still have it , but it has not has not flown in years. This thread has gotten me interested in it again. Left horizontal got damaged in my recent move, a real drawback to a one piece airplane, but I do have another NIB, and also a DL Models (w/scale intakes) version. Maybe I can get it going again

Hey Jimmy,
Hope you made it home safe!! If you have a break can you check the CG on the MB-339 Getting real close to getting
good enough weather to give my 339 a maiden.

Thanks, Arnold

Aileron. 3/4 up and down
Rudder. 1 in left and right
