Today I finished her up. I started with drilling a small hole in the end rib and pulling the Rx antenna thru the wing and out the hole, only about 6" hangs out past the wing. I was ready to mount the motor and I knew I needed to put the bird together to determine motor placement for CG. Putting the wing into the fuse while hooking everything up using extensions coming out the top of the wing proved virtually impossible for me so the 3 leads seem to need to be threaded into the top of the wing and straight into the Rx (or 3" ext coming from Rx) every time. Im not sure I will like this combersome step every time I put It together but time will tell. Anyway the wing went on nicely after all the leads were pulled thru and hooked up to the Rx. I clamped on the motor and could tell right away I was going to need all the nose weight I could get. I roughly determined the placement and installed the motor about as far forward in the mount as possible. I then installed the muffler propellor and spinner. I had an APC 15-4W that I had run on the 91 so I will start with that. I installed a 6 volt 1650 NIMH pack as far up in the leading edge of the wing as I could get and installed the power switch and charge port. The correct starting CG is 6" and I balanced out at about 6.25 inches, well within the range of reason. But a lighter engine is going to make this bird pretty hard to balance IMO. With everything complete I programmed the radio up, set the centers on all the servos gave everything a quick test. So far Im not real impressed with the bluebird servos. They are supposed to be .10 speed but seem pretty slow and they dont allways center perfectly but some of that may be the stiffness of the new hinges. I still need to program rates and expo but she is complete. 6 pounds 1 ounce all up (dry)ready to fly. An OS 91fx should be balistic at 6 lbs
