Want to go to T-rex parts, need help.

[siconic]

I recently purchased a HeliMax MX450 and to say the least I am very disappointed. The tail rotor binds, the tail rotor linkage was too short, It came to me with a bent feathering shaft(and now i have to wait till may to get a replacement free from hobbico), the head is entirely to sloppy, and the blades wont track.

So here is my question: What would it take to switch to the trex parts. What exactly parts wise and mods wise would I need to change the head and tail rotor. The trex head looks much better, and i have heard many talking about the tail rotor being better.

Thank you in advance

these are the parts I used to replace worn parts on mt MX400Pro that has been upgraded /modified to the same as your 450xs.
You should not need to replace your tail case as your heli is new, I replaced my tail case as it was in poor shape. The parts in the links below will bolt/screw on, no mods required. The bearings from your Helimax blade grips will fit the align blade grips or you can buy the bearing set separately. If you want faster cyclic response use the 220mm fly bar and 6 gram paddles, for slower response use shorter fly bar or heavier paddles.
