Pros: powerful, precise, tough. (First batch had a weak swashplate). Good for intermediate and advanced pilots.
Cons: motor tail system, performs slower and not so precise compared to TT o Belt driven tails, but it works good, It won't blow out. Small heli so it's very twitchy.
It's actually very good, and requires low maintenance, easy and cheap to repair. Lots of videos for setup and repairs on you tube. I prefer this over mCPX BL, but still prefer B130X flying characteristics despite how expensive it is to maintain (130x). It's the best rounded 100 class helicopter.
The feathering shaft might have had a very slight bend, so I tried to disassemble it to inspect. While the main shaft was an easy repair, the rotor head had way too much threadlocker on it and seemed to be over tightened during the original assembly. The ends of the feathering shaft were slightly deformed so I couldn't get the bearings off and I finally broke one. The rotor head was almost impossible to disassemble, I finally pried it apart with a hammer, block of wood, screwdiriver and 450 size ball link pliers.
And so, a week and $30 later, I replaced what I messed up and the actual crash damage. That was the easy part. Everything works perfect again.
So what went wrong? That roll rate adjustment on the heli arrives set at the beginner setting. Unless you are a beginner and there is no wind, you NEED to turn it to at least the 11:00 position. To much roll rate, though different, feels like too much expo - a delay between actually moving a stick and the heli responding. When I got the wind gust, I over corrected several times until the shed intervened. After I adjusted the roll rate, it flies so much better.
So for less than the price of an mcpx bl (shop around), you get metal rotor parts and a stabilization system that blows away the Blade AS3X system. The bird much more stable in winds. The aluminum main shaft bends easy, but is cheap & quick to replace.
I originally gave it 4 stars is the awful assembly of the rotor head.
Update Oct 2015
After owning this thing for a while, the bad side comes out. I bought this as a small helicopter, with a better flight stabilization than Blades, that I could try stuff with before risking a bigger chopper. This thing is fragile, you look at it wrong the main shaft gets bent. It nickel and dimes you forever (landing gear, shaft, and a canopy made of eggshell). I ended up flying it conservatively like my bigger helis. A few weeks ago I flew my Nano CPX outside to burn off an extra charged battery, and it was awesome; I had forgotten how much fun indestructible helis can be.
So a couple of days ago, after about 50 flights the 3-1 board quit and the main motor no longer turns. I had just balanced the blades, and tested it in my living room before putting it up. The next time out, I put in a battery, pushed the throttle - and only the tail motor would spin up. I swapped the main motor into the tail motor output and determined the motor was OK. My choices are to either drop $105 on another 3-1, buy another Trex for $220 and cannibalize the old one, or just decommission it into the garage. I decided on the garage choice since it really didn't fit the needs, and the 3-1 is problem prone anyway.
It seems that the ESC on any Trex heli that comes with the MRS stabilization system is garbage. I have all 3 helis (150, 250 & 450 DFCs) and each one has had ESC problems within the first 50 flights. At least with the 250 and bigger you can upgrade the ESC to a Talon. I just installed a Talon in my 450 for half the cost of a Trex 150 3-1.
My recommendation is passing on this POS and spending the extra $50 on the Trex 250. It is a much better flyer, just as fragile, is upgradeable in the future and you get much more heli for the money.
