Hi Guys, looking to assist someone with a Marvelcraft (Fusuno) AS350 and the fitting of T-Rex 700E mechanics with regards to what needs to be done at the tail end to accommodate the rather wide Align tail box. Can anyone that has done this help?

Hey Scott, Why not use a 600E tail gear box instead of the 700? Fits perfectly in the tail and is completely covered. As you know, the 600E and 700E use the same diameter boom and torque tube so its very easy to modify the 700 boom length. The 600 tail box was plenty strong enough on my AS350.
Thanks Phil, Did you have 700 mechanics in your 350? if so did you need to alter boom and TT length?
No, I had a 600ESP with a shortened 700 boom and a standard 700 torque tube. I think from memory I had to shorten the boom about 32mm? to get it the right length to fit the 600 tail box. With the setup I had the main shaft to tail rotor shaft was the exact length to fit the Marvelcraft 350.
ok thanks - do you know if the Align 600 box will fit straight onto a stock 700 boom (locating peg wise) and if so the does TT end up in the same place as a 700 box if say using a 700E mechanics?
Not sure, sorry. Only ever had 600 mech with 700 boom with 600 tail box. Rob (Trooper 7) may know, over the years he has provided a lot of this sort of info over on the other forum.
