I got a new job about a 11 months ago that requires me to travel around the country at least 3 days a week. I'm finally adjusted and the RC bug has bitten me again.

I'm working on a T-Rex 600, rebuilding a Traxxas Hawk I found in my closet (thinking of going brushless if the drive train can support it), eye balling the Kyosho Inferno GT2 1/8th scale can't wait til it comes out.

My RS4 18SS needs a tune up bad or possible a new engin as I haven't been able to get it started for almost a year. My savage just needs a tune as I accidentally filled it with 30% nitro (Damn Trinity Fuel and it's purpleness! And my not paying attention) and now it won't stay running. Hopefully it can be reconditioned back to 20 percent as it ran perfect then.

I also just purchased a Thunder Tiger Ducati 1/5 scale motorcycle that is at the UPS in Bridgeview awaiting Monday delivery (damn them and their no Saturday pick ups!)

So that's it for models, probably will pick up a new Spektrum DX3R since my DX3 (original) has run out of model memory for my collection and future buys.

Great to be back and hope to meet some of you guys at some point this summer.

20 to 30 percent change will not affect tuning that much, something else is wrong (probably just needs to be fully re-tuned).
30% will make the motor run cooler and faster, always run 30% IMO.

20% runs cooler actually

Good info, and I'll keep screwing with that re-tune in the meantime.

I've always had 20% Run Hotter. Methanol Burns hotter than Nitro.

I thought the same thing talked to ed bridges and rich reid about it and they both said more nitro burns hotter more power and less run time

Lol then why is it higher nitro fuels burn cooler. from 20% to 30% engine temps dropped for me.

Why does Odonnell 20% run cooler than Top Fuel 20% ?

Because TF is junk

I only bought it at first because one of the guys at hobbytown said i had to use it in my S-maxx or void the warranty.
I think i might be off the thread subject.

lol how are they gonna know what you burnt in your engine. its BS run byrons. unless blue thunder, makes your engine blue. Lol

Exactaly... What J-Dub said.

Odonnel and Byrons makes your engine have a brown oil coating on it so they will know.
Either way they don't care they just say that to sell more fuel.

figured the brown coating was normal on the piston from combustion Lol. Im going with what Tex said...Traxxas's Customer service wouldnt be what it was if they said "F U, U DIDNT BUY TOP FUEL OOLLOLOLOLOL"

the coating on everything is oil burn off as well as the color. Ive heard some bad things about the byrons gen 2 shit now maybe I should go back to werks fuel
