Gents,

I have been struggling with what to purchase for my next build. I really wanted a plane that would last for many years. All my wood, giant scale, aircraft have about a 2.5 year lifespan before they are basically used up (or I crash them :dontknow ). Plus running smoke ages the aircraft twice as fast and all the covering peels. So I almost pulled the trigger on a composite Krill extra, but I was a little afraid that it wouldn't perform high energy maneuvers as well as I would like. I went back and forth on the Krill for a few months, then I thought, why not have something different. Last week I went ahead and ordered a CARF Chengdu J-10 3D. The jet has pitch/yaw thrust vectoring which should prove to be a blast to fly. This jets claim to fame to that it excels at not only 3D, but it can fly precision aerobatics with ease as well. She has arrived, so let's get started!

Jet: CARF J-10: http://carf-models-usa.com/en/products/ ... -j-10-3d-1
Turbine: Hammer IQ-180+ (180N/39.6 lbs of thrust)
Retracts: Behotec Electric with disc brakes
Servos: MKS 777 on everything.

Like a kid in a candy store, I couldn't wait to unpack it and stick it together. I'm very impressed with the fit/finish, and was absolutely blown away by the weight. Everything seems feather light. Ready to fly dry weight is claimed to be 23lbs.

Got up this morning, coffee in hand, and got to building...

1. Rudder servo and linkages installed

2. Built the servo mounts for the elevons and the canards. Then stared at them, watching the glue dry, for hours. :popcorn Also painted the canard servo mount black to match the carbon fiber it would be mounted to later/

3. Mounted the thrust vector nozzel.

4. While mounting the servos that control the vector nozzel, I ran into my 1st issue. The MKS servos are to deep for the mount and they hit the top of the fuselage before they were completely seated in the mounts. Simply fix, took some 1/8 inch ply, made a shim, and painted black.

5. Mounted the Elevon servos in each wing. I don't like the aluminum clevis they use. It's really tight, not going to be any slop for sure. I'm going to grease between the clevis and the servo arm in hopes of making it rotate a little easier.

Overall, having a great time with the build. I even have my little boy hanging with me most of the time and of course consistently running off with the exact tool I need and any given time.

Ran out of my allocation of attachments in the last post!

6. Mounted the canard servo to the canards.

Sunday morning task... install turbine.

This was one of those measure 3 or 4 hundred times, then drill. The turbine has to be centered in the vector nozzel in the vertical and horizontal direction, then also spaced 2cm from the nozzel (fore/aft). So there was plenty of measuring to do to ensure this was done right. Drilling the first hole was a little nerve racking. I think I broke out into a cold sweat.

I used some clamps to position the turbine. This allowed me to measure/adjust/measure/adjust relatively easy.

The kit also comes with shims to center the turbine (left/right) in the nozzel. Took some patience, but finally got it all squared away.
