1/2 tank lean fix?

[DreamState]

Ok I have searched. Is there a definite 1/2 tank lean fix for the revo? Does the uniflow mod work on the revo?

Uniflow does not fix anything, it only masks a problem. If it is leaning out, your tune is off or you have a small leak somewhere. Sometimes worn bearings cause tuning issues. Revos are famous for leaky tank lid seals. The 3.3 and stock pipe likes a short pressure line for some odd reason too.
Best thing to do IMO, is Buy the Tekno rx box conversion and a MBX5T 160cc fuel tank. I loved that setup on my Revo.

All nitro RC's have some leaning at half tank...I was taught to tune on a half tank then filler up and go go go. Since I've been doing that it's been running great.

True but some fuel tanks are way worse about it. The Savage is a good example. Night and day difference.

Thanks for the info, but my tune is not off and my picco is sealed as well as my tank. Guess I could try a longer pressure line. Something has to work it is just a pressure regulation issue. I have it tuned for under half tank now, but I would like to have that power and responsiveness from full tank all the way through. Not to mention tuned like that you are running rich from full to half and eating up expensive nitro. Like I said something has to work, it is just a pressure problem.

You can either run your tank above or below the carb to fix this problem. Having the carb in line with the tank exposes it to siphon and gravity feeding, the difference between the two is what causes the problem. Moving the tank will give you only one variable to play with, tuning will be much more accurate as the effects of only one variable will hardly be notices in comparison. Eliminating one doesn't solve the issue 100% but that isn't possible without a positive fuel supply (electric pump).

I'll have to give that a try. Good info. Thanks.
