Ok I got my T-Rex in the mail yesterday. I started on it immediately. I took my time and it was finished in 4 hours. I think mounting the motor screws took an hour. Here is my setup:

Align BL outrunner with 13 tooth pinion.
CC 35 with 3 HS55's and 1 HS50
GY240
Berg 5 with DSP
TP 3 Cell 2100

The build went really smooth I thought. This is my first helicopter kit. Do they always include the tools needed to build it. I was impressed by that nice touch. Great kit I think. I used the instructions and never got stumpped at any step. It helps to really measure the linkages or at liest make them symeterical. I used the default measurements and its been fine. I made one little adjustment for blade tracking. You have to move all your linkages in to the closest hole on the control horn. This thing is hard to control if you leave them out like I had. I worked to try and remove all the slop from the washout arms and z bends. I was able to get it better and its ok the way it is. I dont consider the slop to much of a problem yet. The first few flights have been ok. Its deffinately a little harder to fly then the Shogun. Maybe im still making the adjustment. Im over all impressed with it. When im in a hover the throttle is at about 65%. It deffinately needs a motor that can put out more power. It fine for now and will not interfere with my flying. At flying weight with the above setup it weighed in at 640 grams. Thats a full 90 grams over my old shogun before I ditched it to get a real heli. I got 12 min fly times and the battery stayed barely warm. The motor on the other hand will conveinently remove any unwanted figerprints from your finger if you try and touch it after a flight. I wanted to take it on one last flight for the day but it got dark. So I flew it in my house and of course I landed and hit the blades on a sliding door. They shattered and went everywhere. I slapped a new pair of stock woodies on there and prayed that there would be no vibration and it was all good. There is a very small amount of vibration in it now prob becasue I bent the feathering shaft. Its not so bad that Im going to replace it. I took it up for one more flight since then and even with a slight bend in the feathering shaf it still had less vibrations then my shoguns ever did. Overall I give it 2 thumbs up. First for making a very well thought out kit and for making a well thought out helicopter. Now if they can just get us a better motor or shave 100 grams off this thing we would be in heaven.

First crash...

Check the main shaft also. I had a similiar problem a few weeks ago when I hit some plastic patio furniture and the heli flipped on its side. Turns out I snapped both upper mixing levers, bent the feathering spindle, and also slightly bent the mainshaft.

All have been replaced and I was back having fun today.

I gave it a good inspection and another test fly its fine. Im sure I will get another chance to really smack the blades again. I never get away without having to replace the main shaft, and spindle. It was already on the ground and the tips of the blades hit the door. The heli never tipped over or anything. It just shattered the blades at the tip. Got lucky with that one. Im really good and breaking things sometimes. I need to be more carefull. This isnt a a good indoor heli. Ill try not to make anymore flights inside. Ill just wait until the sun comes up. I need supervision I tell you.

Well I brought it back out to the park today. I finally have normal mode, idle1, and idle2 set up. I have never had a fully capable 3D helicopter before. Im not couting the shogun. It never made it past reliable sport flying for me. I feel like this thing will do anything I tell it. The reason its was harder for me to control then the shogun is becasue its a more acrobatic machine. After a handfull of flights Im getting close to trusting it for some mile acrobatics. Im still learning so Im not dying to crash this thing. I do trust it though. It flies straight and true even in good wind. I live in South Florida near the coast. I get plenty of 20 mph sustained breezes off the coast. The shogun was a handfull in the wind. My HB was only able to fly in mild wind. So far I dont see the wind really bieng a problem for this thing at all. I admit to learning in windy conditions and have an understanding for the wind. With practice windy days can be lots of fun without much additional risk if you can anticipate how it will hit the heli. OH here is the other big PLUS!!!! I didnt break anything today. I dont even think this thing is fully broken in. It feels so much more solid. The Shogun never gave me this feeling of trust. Even the guys at my public AMA field we have here in Broward county Florida are really starting to take interest in these electrics. This helicopter might be the start of a change for the whole helicopter hobby. I flew nitro planes and let me tell you I dont want to carry around a starter box and all the fuel. I just walk up with my transmitter case and my heli. Thats it.
