RE: W.M. Extra 300 S
Am contemplating on dropping those weights out and working the cg with the fuel tank what I will do is make an additional support plate to move the weight of the fuel tank backwards, if I am not mistaken that will balance out the cg nicely.
I feel that she can do even better with more weight of her. the vertical pullouts are okay, still heavy though, compared to my hangar 9 extra 260 this baby takes a while.
Will see if I get sometime this week to work on the cg.
RC4life did you fly her yet ?
