thanks for the help i think im going to go with 2 of the 2100 3 cell thunderpower batteries for my mega 16/15/2 .i bought this thing from hobby barn thier instructions really are bad.well i tried to put in 8mm for my elevator throw but i can only get 6.85 mm for the up becuase the elevator is hitting the bottom of the jet.is that enough throw if not what can i do to get more,wasnt sure if anyone has had this problem.also does it matter if i make the hole on the left or the right for the exit of the elevator linkage, just wondering becuase the bottom of the jet is warped a little on the mold and thats where it is hitting, so basically if your looking at where the elevator goes up the left bottom part of the jet is a little higher then the right causing it to hit,so basically i was wondering if i could cut the hole on the right side where it is bottoming out.also had one more quistion i am using hs 55 servos for the wing i was wondering if you are looking at the jet from the bottom on a flat surface should the servos be touching or should the jet be sitting on the bottom of the fuse with the servos not touching just wondering dont want to rip anything out trying to land, thanks for all the help, ted
