Hello all....
Could anyone please tell me the recomended location of the center of gravity on DP Ultimate 120. I would also be interested to hear any possible changes to that location. I have misplaced my manual and can't get anyone to answer at DP. Please help.....
I have been flying plane with OS160/bison muffler/du-bro mount, 24oz tank, heavy 1900 5 cell pack, and all Hitec digital servos. First of all I'm flying at 6000ft altitude and it makes a big differance in power. The plane flew well and I liked it but even with the big motor vertical was not that great and hovering was not posible and beleive me I tried every prop ....I beleive set up to be to heavy for my tastes so I made a few changes: went to YS120ac and used stock DP motor mount and no muffler saved about 1lb there.16oz tank and lighter battery pack saved another 1lb so I hoping for better performance with the lighter set up but the plane is balancing out about one inch back of where I was with the old set up and I'm not wanting to ad weight.Currently the plane is balancing out at 6" in from the leading edge of the top wing and I think it should be at 51/4".Thanks..............Lou
