RE: Yellow F22 Build
Joe,
Yes, I'm sending it to him for the measurements. I'd like a bigger pipe for the 180, but there is no way to get it in w/o crushing it to squeeze into the opening. I'm going to go with a vector pipe without the movable tail section, I don't have time to mess with it. The pipe will be like the JL F-22 pipe, I just want it sized perfectly for the Yellow. I'm getting ready to head out to the post office soon.

Well take it for what its worth but IMO the stock thrust vectoring pipe is a flawed design and should not be used. You might get 50 to 100 flights on it but it will fail and needs to be inspected often. My damage was hard to see installed so remove the pipe and inspect it if you stay with the yellow pipe.
The aircraft is only as good as the pipe. If that pipe fails then you have nothing. I will not save money on the pipe.

What I have only seen at Tam's site is for an integrated pipe together with the round VT swivels.

Gunradd, do you have a pic up the nozzles where you interface Tam's pipe with the YA VT nozzles?

The difference is the yellow pipe has the double wall cut back so it fits into the thrust vectoring. This is a flawed design. The exhaust comming out of the inner pipe creats a low pressure area and that is what sucks the cooling air through the double wall. With the double wall cut back like the yellow pipe it does not pull cooling air around the double wall.
My tams pipe has the double wall portion installed into the thrust vectoring so it pulls the cooling air through the double wall. Here is a pic of the rear of the tam pipe. The entire thing fits into the yellow thrust vectoring.

RE: Yellow F22 Build
George,
IT is funny, I had Tam make that pipe years ago just because I had run his pipe in the F18F. I thought the Yellow pipe was fine but I had tried the Tam Kool_aid...
I am sorry that the other plane above had a failure but very happy that it likely saved several other planes.
Hope you have have fun with it when it is all back together.

I may just list the tailpipe unless it goes quickly through this thread.
Will try to post a picture.

I wish it was a vectoring pipe, then I'd take it. I'm having to much fun with the thrust vectoring now

If anyone is on the fence about getting the vectoring just get it. It helps so much at slow speeds with control and getting off on short runways alone is worth it. People are scared of it for some reason but when set up right all it does is help it fly better. I have even been thinking about re trimming knife edge flight with it on and then just leaving it on all the time. The only time I really don't have it on now is for long slow rolls and 4 point rolls. It lands better and takes off better with it on even though the yellow manual for it says to never use it for takeoff and landing.

Just get the one from Dave![8D]

Thank you guys! Looks like I will be saving up to get a Tams pipe as well.

Mine is all apart right now getting the gears changed out in the 8711 stab servos...... The amount of play I was getting on them was getting pretty bad. Also fixing the canopy after it departed at topgun. When I get it back together I will get you a pic.

I just saw this. I know it's old, but this isn't quite accurate. The VT portion of the pipe is, in effect, an extension of the outer wall and it draws PLENTY of cool air around the mass of hot exhaust. If in doubt, simply run the engine at different settings and feel the skin temp above the pipe. Further, I'd remind you that even the best products have issues from time to time and our pipes are fine.

RE: Yellow F22 Build
Shaun I agree yellow pipes are fine with no thrust vectoring though. I do not believe the thrust vectoring pipe is fine. I am fairly certain I can burn another one up in 50 or so flights if I had another one. And the first one I burnt up with a 120 size engine now I have a 170. But it does not matter since yellow does not make the pipe anymore anyway. Its just my opinion and nothing more.
Mine is almost back together aside from the elevator servos. Waiting on the new gear sets for the 8711s. Cant wait for Kentucky jets this year!

Well, the new pipe arrived around 3:30 today; several hours later with some head-scratching, "dremeling", a couple trips to the trailer, a trip to a buddy's, a small break for dinner and to let some hysol set-up, the new Tam's TV pipe is installed and ready for a maiden after I double check the CG.
I'm heading to First In Flight tomorrow, so Wed. should be the day. I didn't take any install pics, but will try to get a couple in the A.M., time for bed for now!

RE: Yellow F22 Build
MAN!!! I wish I would have known that a while ago Shaun. Like Kris said, it won't last long I'm sure.
Kris,
I got a little time on it today, it definitely has promise. Although I did a quick check of the CG before I flew it, it was obvious on landing that the CG had shifted aft. It needed a click or two of down trim as soon as I took off, but it was on landing approach that it became noticeable. It was very pitch sensitive during landing which it never was before. And no, I did not have the TV on during landing. I almost got in trouble,but all is well. I have moved my two rx batteries forward and moved the engine forward inside the mount. It started raining before I could get in another flight though. I'll try tomorrow, but the weather may not cooperate.
Oh yeah, I also mixed in tailerons when the the TV is active for the next flight.
