Default Different versions of trex 450

can anyone tell me what is different in the version 1,2 and 3 of trex 450. Does version 3 have a belt to drive the rear rotor or shaft drive with helical gear at rear? looking at buying pro model but have noticed some are belt and some are shaft. Which one is the newest one. regards

v3 has torque tube (the shaft drive) and a new frame also the newest series. v2 has some rotor head upgrades over v1, but other than that i think V1 and V2 are very similar. v

v1 and v2 = belt drive.     v3(450 pro)= shaft drive.    450 PRO FTW!

V2 has an upgraded head compared to V1. V3's head is yet another upgrade from the V2 giving the heli more stability - some claim it flies more like a 500. V3 SPORT has a belt and is supposedly easier to work on with the V2-like frame. V3 PRO has a torque tube (TT) and no belt with a new designed frame that may be harder to work on. PRO and SPORT are the newest versions

So if one were looking at a 450 Pro vs. a 450 Sport, which is the better choice? Do they fly much differently, or is the difference in ease of maintenance and a slight lower cost for the sport?

How about the 450 SA versus SE versus PRO etc. I"m looking at an SA model with a bunch of upgrades.

I started out with an SA and while it was ok for a while the plastic head components wear quickly. I have upgraded now to a V1 head and it has made a big difference in the way it flies.

Better choice? Well the PRO is designed more for the advanced user who doesn't crash as much. The design is more difficult to work on, takes more time to work on. Some say the torque tube (geared tail rotor) design can cause stripped gears in a crash. PRO is a whole new design which is nice for some whereas the SPORT is more of an upgraded V2 (the trex 450 model before the SPORT/PRO) If you don't crash often, the PRO is probably the way to go. Otherwise, go with the SPORT. The SPORT's frame is easier to work on and take apart. You still have to worry about belt tension, belt slippage or wear with the SPORT.


My answer is based just off of reading others experiences because I haven't experienced them first hand...As such I was researching a lot to buy my first CP bird. I of course went with the SPORT super combo which just means it comes with esc, motor, servos, gyro. JUST add a tx, rx, batteries. Since crashing for me will be inevitable, I went with the SPORT. According to Bert Kammerer, the average flier will not be able to tell a huge difference when flying a pro vs a sport. I know, I sure as heck won't.

Hey, thanks for the input. I am a little weary of the torque tube design from Align. A member of my club just built 2 T-Rex 700's, and BOTH of them have quite a bit of slop in the gears. He is a great builder and was quite surprised to see this (he's been flying heli's for about 20 years). On the other hand, the belt design has its drawbacks, like having to watch the tension.
