The saito 180 weighs 880gms...if u put anything lighter up front , it will be more tail heavy. I was using micro hitec hs81 for the throttle...but i changed that to a normal futaba 148 as the tail was heavy. The best idea is to reduce wt. in the tail by making holes...let me know how you make those holes...saving wt. up front wont be much help, unless u reduce tail wt.

Moreove, I will get an MK bellcrank and move the tail elevator servos upfront. The rudder servo is already under the tube.
