ok. so i have built this 4 star 40 perfectly to plan. everything is together and covered. added my reciever and seros. slap on the 46 LA that the plans call for and the thing is EXTREMELY tail heavy!! so i move everything as far forward as I can and it is still tail heavy. i often add weight to the tail to balance most planes due to a larger engine. however, i did not want to add too big an engine onto this plane. i have been flying for a while and i hate adding dead weight to my planes, but i am wondering if i should remove the 46LA and place a heavier OS 91 4 stroker on it to help balance that weight. I know that the 91 is way more than needed (power wise), but if I am going to add weight to the nose it might as well be in the form of a larger engine.

has anyone had this same problem??? has anyone placed a 91 4-stroke on a 4*40??

its all in throttle control.......to a point...

any thoughts???????
