So I was wondering...does anybody know if it's any good or not. I've not seen it mentioned much.

From what Ive seen its a nice looking heli, theres a side by side shot of the T-Rex and a SJM400 on Helifreak.

One of the guys at our field just bought one recently...
Shame I've never really seen him doing anything more than hovering maximum 2ft off the ground, having the tail drifting around, slamming it back on the ground again, screwing on the settings of the gyro, lifting it again, again drifting, again whamming... :dontknow:
So I can't say anything on its flying characteristics, but I'd bet that - if you put a descent pilot (yes, I'd volunteer... ;) ) on the TX - there can't go much wrong...
From the mechanical point of view, it has quite some interesting points in its design.
Almost everything appears perfect...
The only thing I noted on the one I saw, is the quite small motor (I do not know whether he installed the original one).
"Incidently", CG appeared to be aft :wink: , so I really think there should be something else than that tiny engine... If there was something bigger, it would be heavier, moving the CG forward...
My Zoom is also 400-class. Of course its heavier, but the motor has nevertheless twice the size...
Amazing also the price, I almost paid the same for my Zoom about 9 months ago... :arggg:
Its sold here for just below 300.- CHF, which is roughly just below 200$... :bomb:
I *wish* I'd found some secret wallet somewhere... ;)
Cheers,
Daniel

The pro's:
- Cheap
- All alu/cf
- Great head system
- Very lightweight
- Cool design
The Con's:
- Cheap
- Very small and fragile alu parts
- Hard and time consuming parts removal
- Glued on tail
- Bad tail construction, binding evident
Conclusion: Great looking bird with good flying characteristics but a ***** to work on replacing parts.
If you like fiddling with microscopic crubscrews and want a goodlooking heli for an unbeatable price, then this is for you.
Otherwise save a bit more and get a T-Rex.
