Roger, I'm afraid the TT Redline carb is terminally flawed. If you don't want to swap carbs, you can try a push-pull setup on the carb with a strong servo. I have seen the Futaba 9452 work with the push-pull, but the carb will still be notchy at best. The Redline does make good power though. It's a shame about the POS carb!

Also, if you use the Redline carb, please make sure to check that it returned to the low position before you start the engine. Me and another in my RC club had hot starts from this. His stuck at half throttle, mine was stuck at full!

Apart from how the white boss is secured to the engine that looks to be the way tmoore described how he might do his mod.

There was a post about removing the spring inside the carb. Any idea if that helps?

You can remove the spring or you can stretch the spring. Either one does absolutely nothing but cause you grief. Considering the nice machining and design of the rest of the engine, the carb is nothing but an abortion. I've sent both of mine back and had them modded, one works OK but just OK the other one is a total waste of my time. My flying partner has an original carb that works great but pisses fuel around the inlet nipple but does run great and he refuses to send it in to get it "fixed" until it absolutely won't work at all. I'm not bagging on the engine as a whole but the carb is nothing but a crap shoot. In its stock form, it simply isn't worth the time and effort, that's why I'm getting ready to mod the OS carb and machine an adapter. I have two engines that are essentially worthless to me so the carb is an easy fix. I'm sure Kim is right about this mod, the OS carb has to work better. When the HZ carb comes out it may work even better on this engine than it does on the HZ, it's hard to say.

If TT is really serious about keeping this engine on the market, they have to re-engineer the carb to a higher standard where there is no camming action with the barrel. In order to be reliable, the barrel only needs to rotate not cam in and out.

For the guys posting results on this... if you don't mind could you state what OS carb you are using? (60LH, 40-E etc.)

Thanks!!!

I just finished proving out the CNC program and will cut a few adapters tomorrow. The carb body will need to be modded to make it work and the carb will sit up a little higher than normal but should fit under a normal shroud like a Raptor or SDX. A TRex may have to be relieved a little.

I'll know more this weekend when I put it in a machine. If this works like everyone has been reporting this may breathe new life into the Redline and motivate TT to fix the carb. It won't be a good deal if you have to buy 60L carbs to make the thing work.

The only problem with doing this plate is that the carb needs to be shortened by a corresponding amount.

I used the 60B 3 needle and had better luck with the 60L on the Hyper 50 , but that would be interesting if that HZ carb would be better or not . The 60L has no transitons problems at all on the TT53 .
