Default messy body, from muffler

Hello, i have an HPI Nitro RS4 3 evo +, every time I race my little bugger he tends to get greasy(a lot of exhaust) all over the right side where the exhaust is mounted. Is there any thing i can do to help my body stay cleaner so i dont have to clean it after every run?


maybe i can tune my engine to stop running so dirty?

Thanks for all the advise.

The only thing you can do is clean the body after you run the car.

You may be able to try pointing the exhaust tip towards the ground. I have always just cleaned it and not really ever worried about it. But I think that unfortunately you are probably just going to have to live with it. Just my .02 worth.

if you use cheap nasty fuel with cheap oil less of it will burn away leaving a big mess

If your motor is running really rich it will leave heaps of un burnt fuel and gunk all over your body, i would just wipe it up. Or check your tune you may be able to lean it out a bit and then it wont leave as much crap. But no matter what you will always get more build up of gunk on the exhaust side than what you would on the other no matter what tune you have.

Default Best Advice

I think the best dvice is to use an exhaust deflector, such as the one on this website...

http://www3.towerhobbies.com/cgi-bin...&I=LXRHT0&P=FR

I use one and it works just fine, if not you can switch to a rear exhaust..

from TSAIS

check it out:

here you go you can use an exhaust deflector I cut mine very short just outside the body to try and minimise any restrictions. it also stops exhaust residue going to the rear wheel. this is a venom deflector.
cheers

go to an automotive shop and ask for heater hose,fit the hose over the exhaust tip and run it out to the back inside the body .secure it to the shock towers.
all the mess goes traight out the back not on the body.heater hose is about 5 per meter

nice NT1 there Aussies. so ya made the transition hey. good luck.
as for Ash Cobb , no matter what fuel one uses , there will always be oil residue. if there is none, then your in trouble man, may want to stick to electric hey.

only due to your advice given. seemed strange to me that was all. you are an electric driver. and you are famous on here for all the wrong reasons.
so my $130 bottle of Runner Time is cheap and nasty. all fuels will leave residue, its a part of nitro racing. there is oil in the fuel. and as i said if it all gets burnt, then its not doing a very good job of lubricating your engine. if one wants to reduce residue, then id suggest to run a racing mix with higher quality oils , but less of it. thats the difference from the stuff mixed at the LHS, or getting a bottle of runner time or Byrons. but doing this means you will have less tuning tolerance from a high percentage oil content fuel. so its not for beginners to run a race blend. the tubing on the exhaust is quite usefull, but not legal in sanctioned events. but for a non racer, its not a problem.

Nope not racing electric anymore.

I didn't say that Runner Time was cheap and nasty, all 2 stroke fuels will leave a residue but cheaper fuels will leave more residue.

I could of worded my first post better.
