Hey, Gang !
Got the kit with all the spare parts Yesterday. Put the decals on the canopy while at work, got home and got busy on the rest of it.
I was really impressed by the head assy. and most of the tail for such a little heli.
I knew what to expect, but this IS really the same size of the CX.
Got the tail done, and dialed in good; installed the blue bird servos, ran the wiring, set up the swash and head to the best of My ability; taking extra time to get that right (in My mind). Carpeted the lower frame with Velcro hook, padded and carpet velcro'd a square on the gy401 and tucked it in (will have to do some serious wire cutting on that later)!
Okay, enough of this careful building; it's getting late. I gotta get it in the air ! !
I started to wind the excess wiring from the gyro around the left skid, zip tied what I thought would get to any moving part including the spinning motor can, slapped a SMC 22C 800MAh battery in, velcroed it, and off to the home theatre room !
I set up the pitch curves to give Me what I estimated -4 or -5, 0, +12 or so in the DX-7.
I put in some expo, and lowered the values in the swash mix except the pitch, of course.
Set it on the carpet in the home theatre, canopyless with its guts hanging out spilling around the skids, and spooled it up. It Soft started and I Immediately noticed how quiet this thing is ! I was expecting the piney, whiney sound of a CX with stock motors.
Got it light on the skids, checked the blade tracking; PERFECT DISC!
Tested the rudder, and it nodded okay.
Gave it some more collective and it very smoothly, and full scale realistically took off and it Hung in front of Me, chest level, like a Hummingbird waiting it's next command ! It hung there like it was bored !
Most of My nervousness gone by now, I carefully slid it back and forth, to and fro; expecting the unexpected, but it was obediant and totally predictable. Did some side hovering, throttle pumping; tail little loose, so landed, pumped up the throttle curve to 0,50,80,90,100 (same as TREX), took off, and that pretty much cured it; but clicked the Gain to 75%. Now it's PERFECT !
By the third battery pack, I managed a pirohuette (1) and didn't manage to crash it in a 5 foot square flying area that I had with the furniture and all.
Got a solid 6 minutes on the old CX-2 packs with 2,450 Tached headspeed.
After about 3 tail strikes on the carpet, the tail started to wag a bit and upon inspection of the tail noticed the tail shaft gear was slipping (I was warned of that), 10 minutes later and some red lock-tite, the tail is rock steady again.
I think I'm gonna replace the piano wire tail linkage with slightly thicker C.F. like I did on the TREX.
In short, I was half expecting a buzzing hornet that was hardly controllable; What I got was a T-REX 200 ! !
Was it worth all the Money?
ABSOLUTELY ! !
