Well I put all the good stuff in. The battery, ESC, receiver all positioned rearward.
Much to my surprise, balance check showed very nose heavy, needing about 8 plus oz of weight to the tail to correct. Not acceptable..
Plane B. Removed the A4120-7, and installed the U3520-6. Fortunately, I had used these same 2 motors in another project so that the mountings were all ready set,and it was a pure boltin. This also changed the power from 6 to 5 cell A123. Back on the balancer, and was able to balance out slightly nose down.with 1.5 oz added to tail.
This should be a very good combination for this plane since the total package is very close in size and weight as 3 other planes in my fleet. And they have the same power set-up. It also gives me option of different battery selections that I already use in the other planes.
