Just maidened the TRex 600 NSP

[Made2Fade]

Well guys ive just given the TRex 600 Nitro Super Pro its first maiden flight and it was very successful indeed. What a super smooth helicopter to fly! Now got everything programmed and all i have to do is put another 4 or 5 tanks through her to run the engine in. Will probably do that on sunday weather permitting. There was one little hicup i did have. Im running a spartan 760 mounted on the stock gyro mounting position behind the canopy and using the method described in the spartan manual (metal plate with thick pad on bottom and thin pad on top). Now because im running the engine in its nice and rich and ill obviously be doing that throughout the next 4 tanks. Because of this im getting a very slight vibrating throughout the frames etc. These vibes are transfering through to the gyro simply because the stock Align gyro mount is almost right above the engine. Bearing in mind this is the engines first tank of fuel... when idling if i look at the gyro i can physically see it vibrating until i give it some throttle. Now it didnt really show up in flight but im worried these vibes (maybe i should use the word buzzing as thats what it sounds like really) will do something to the gyro causing it to fail in some way and let go of the tail which would obviously cause me problems. Has anyone had the same issues using this combo? I was contemplating modifying the frames just behind the swash plate. Then i could fit the gyro mount there as its further away from the engine and seemed to be less noise there. Check out the picture and you can see the flat space behind the swashplate. Im sure this would cure the problem. Has anyone done this? Any input appriciated. Trying to be safe rather than sorry with this. This is the only prob i came across to be honest and the helicopter flew brilliantly. Managed to set my idleups/throttle hold and cut/gyro gain and end points/swash afr for cyclics and pitch all in 1 flight so im quite happy with that. Cant wait for sunday so i can get this baby broken in properly. I can see this helicopter being very favourable in my fleet.

well done Lee sounds like a success.

on the next flight youll have it leaned a little bit more and the vibrations will smooth out so shouldnt be aproblem unless they really are bad in which case its more than just a rich engine causing it, which I doubt very much.

everyone at our field has the gyro mounted where you describe and I dont recall anyone having a problem.

might just be me then... im very cautious after that crash with the knight sport at the Park Hall fly-in. Ill see after ive put another few tanks through her and start leaning the engine out.

Nice one Lee. Wondered how long it was gonna take before you got her in the air.

Can't really give any advise on the vibration problem but just want to say thanks for the picture. Was gonna put a post up asking how to do the tubing with a header tank but now i don't.

Move the Gyro to the back plate behind the swash and the shake will go away on the tail.

I never got rid of the shake you'll see on the skids in a hover and flying etc...

Well done mate, another happy chappy then.

To be honest like i say it doesnt affect it in flight im just be cautious to be honest. I can literally see the spartan vibrating at idle but as soon as i increase throttle it goes anyways. Ill see what its like after the engines a bit more broken in and if im not happy ill just mod the frame at the rear and put the gyro mount there. Well happy with the helicopter though and this little snag is nothing really. Nothing when i compare it to other issues ive had with other helicopters anyways.

Richard heres another pic for ya for the header tank mate. Probs give ya a better idea.

nice.... love the black paddles... i got the red one and it came with the ugly white paddles and tailblades. please let us know if your vibration problem is gone after breaking-in your engine.. gudluck

[Richard H]

Nice one Lee.

Really appreciate that!!

[Made2Fade]

Its probably nothing... just a little concerning. Im being cautious. Might take a video of it next time i take her out so i can show yaz what i mean. No biggy though as it will take me 2 minutes to mod the frame behind the swash plate so i can fit the gyro mount there. No problems with the piccys Richard... if your after any more even of other bits/models then please dont hesitate to ask. Its what were all here for.
