Hi ALL,
I have been having a hard time in matching My align Trex 600 electric heli to funkey agusta 109 a.I got 2 fuselage one with the retracts and nother with the fixed landing gear.
the only problem which i faced was with the fuselage ws with the head area.
If i mount the mechanics without using any elevationthen the flybar of the heli hits the top of the fuselage.then i tried wit mounting the mechanics (heli) with elevation (a balsa wood plank below) the head problem was solved ,but the push rod in the head assembly is touching the fuselage inner wall.Which is infact pushing the front part of the fuselage away by 3mm.
After all these i brought a new thunder tiger raptor E620 thinking the raptor has the flybar on the top of the head.even this ended with a failure,the frame of the heli is too long ,so the mechanics cant be placed in.

My question is has anyone tried with this fuselage (fun-key...thinking that the seller sold the heli saying this was fun-key brand) and what mechanics (which heli)
did u use??

I have attached few pixs for better understanding

Thanks In Advance
