Here is a few pictures of my TT53 (V2) mounted in my T-Rex 600NP for those who need to see the new carb and needle valves.

Are you guys posting those pictures on my behalf? I have v2 carbs...My issue is that both my v2 carbs are sticking. I appreciate the thought...if that's what you were doing. I originally had a v1 engine and sent the carb in for replacement and recently bought another redline which came with a v2 carb.

Just hoping to get some insight into why I am experiencing sticking issues with the new ones.

ok

This is what I suggest you do, pull the motor and check your fan balance if that is good dial the fan on the motor and see how much run out have, you might have a high freq vid caused by the run out of the fan hub causing the barrel to wear on the screw that holds it in place which will give you a rough spot.I would not remove the spring this will cause the barrel to move in the carb body, your fuel mixer will change when flying.In the picture you posted of you heli i can see the carb i know your say its V2 but i cant see it sorry to point this out Dino.

Just to prove this is V2, here are some more photos of the entire carb. As stated..this is v2.

If it is vibrations that causes this, then I am going to be out of luck solving it. It is on a TREX600...not much can be adjusted there. I did balance the fan and hub using a Dubro TruSpin, but that's as good as it is going to get.

well

see if you can dial the fan unit on the crank and lets see how bad it is does the hub lock in with the key or just a compression fit let me know, if you can turn the hub and find a better spot to dial that would be key, we have many of the V2 carbs out there now and so far no one has told me about the sticking problems with them thanks for the picture Dino

I was going to fly today and took it out to try out my new christmas temperatur gauge. Flew about 1/4 of a tank and brought it down and the carb was so tight and stuck that the ball link was flexing on the arm. I took the engine out and fiddled with the carb myself and it was infact extremely sticky. The thing would barely turn. This carb...the one I have not pictured, has no wear marks on the barrel, but does have the same wear mark inside the groove.

OK, so here is the only thing I can think of.

I am running the New Magnum Dynamic Series Heli 30 fuel. Is it possible that this blend of fuel is somehow not jiving with the carb/barrel material?

I am now going to completely swap carbs out and have cut the spring in half to reduce some of the resistance. I am going to try running it with WildCat 30% and then come back and run it with Magnum DS Heli 30 and see if there is a noticable difference in resistance.

I believe, regardless of the results, I am going to need a new carb because of the wear in the grooves.

Anyone out there running the Magnum DS fuel and have any suggestions here?

I won't read through three pages to see if it's been posted but, if you over-tighten the carb mounting bolts, you can get binding in the barrel....

Sorry if it's been covered.

I have proven that Magnum Dynamic Series Heli 30 is the cause of my sticking.

After rebuilding the carb and starting with it smooth as glass I performed the following test:

Flight 1 WildCat CY 30% - Carb Smooth and Free
Flight 2 Magnum DS 30 - Carb Tight and sticky
Flight 3 WildCat CY 30% - Carb Smooth and Free

Because I had a hunch this Magnum was the cause, I decided to run it second so that if the carb got sticky, the 3rd flight with WildCat would have a chance to free it up.

I took off on the 3rd flight (Cy30%) with the carb still sticking and just worked my way thru it into Idle up. Stick banged the entire tank and landed. Carb is silky smooth again.

Apparently the ingredients of the Magnum are not working well with the RedLine carb. I believe, from what I have witnessed, the magnum is not maintaining a good lube. The carb, after running WildCat, has a gummy feeling. After Magnum, it is very metalic and not as oily. Whatever is in the Magnum is causing some kind of friction and resistance.

I believe the secret ingredient in the Magnum is Nitrous Oxide, but I can't confirm that. I believe this is causing the oil to not properly build up on the barrel of the carb and is causing the sticking. And if it isn't NOS...then something else is causing the oil to not build up and I am losing proper lubrication.

Fuel runs fine in my YS91SR without any issues like this...but the carbs are completley different. Unfortunately I still have 7 gallons of this new stuff...so I will have to just run it thru the YS for now and get back on Nitro with the RedLine.

Edit: I went back over this, and just to be clear...this is not a hit against magnum fuels..This was more of a carb issue. I love the performance of the fuel and will continue to run it in my YS91SR. Makes great power and is much cheaper than Nitro. My intention is not to make this about the fuel. That's why I am sending the carb to Buzz at magnum to check out. It could be the carb, could be the fuel...who knows. All I know is that different fuels give "me" different results on the carb. Don't want anyone getting the wrong impression about the fuels from my post. Buzz says the RedLine was one of the best performing engines on the new fuel (I will agree, awsome power) and that I was the only person so far with an issue like this...again, which is why I am sending him my carb. If it turns out that I just got a bad run of carbs...I will absolutely keep using the new DS fuel in my redline.

Dino, thank you very much for baring with me while I worked this out. I will send them in next week. I am just glad I was able to figure it out...didn't make any sense that the carbs would work fine and "BOTH" suddently stop working at the same time...the same time I am running the new fuel. I should have honed in on it much sooner. I truly appreciate the help.

Sending one of the Carbs to Buzz to inspect and test with. All boxed up and ready to go. Once he gets done with it, I will send it on over to Ace.

hi

I live in Arizona.. I had to turn the mid in HALF TURN lean from factory, and 2.5 on the high... Im using Hatorai 523..

I have one gallon through this motor and just connected my Multigov.. Since breaking in, Ive ONLY turned the HIGH in two clicks... My head temp after hard 3D is 165 degrees.. the backplate is cool to touch... I havent touched the needles since breaking it in.. Its still running very rich but produces very GOOD power..

Align rep tic toced it 20 times in a row and it begged for more... So I would say its tuned really good right now.

yes, I have the new carb.

Michael

Crash-Prone and overcoming it!!!

This is great reading this. I just got me a TT Redline 53 yesterday (Friday Jan 2nd 2009). I ran 2 tanks of fuel through it today (Saturday 3rd) only to find out I have the old carb. On its first flight (hovering lazy 8s) just for running it suddenly went lean and started reving high so I landed. Sounded like it was about to run out of fuel. For the brits on here I got it at SMC in Worthing so it will be interesting to see what they say about it when I phone them Monday morning.

Your sudden change in revs or lean run would have nothing to do with an older carby where the problem was sticking barrel after quite a few flights.
I have ordered a new Vibe50 and it will get a new TT53 engine. I already have one in the R50SE.
I am more impressed with my TT53 then my YS50 which is in a different new heli.

The newest engines come with two extra head shims as well in a packet.

I would agree with alfred..... look for restriction (s) in your fuel delivery system.... how old is the fuel tubing ?? the cheap fuel line that comes with most heli kits are junk. This fuel tubing becomes mushy and collapses, causing problems as you describe and should be replaced with decent quality stuff.... could be as simple as that but we need more details from you to be able to offer other suggestions.....

My TT53 did exactly the same thing today. Its only had 4 tanks of fuel through it and on the last flight it went into silly mode. Over reving in normal mode while trying to land and screaming while at half throttle. I guess I have not made the right move getting this engine.
