Hi guys,

I've been following this thread for some time. A month ago I bought a brand new RB X12 5 port engine for my HPI car and the old FE is now on the shelf collecting dust. I'm new to RC but want to learn more and get good at it. I know that the FE isn't really the greatest powerplant in the world but maybe I will learn something for engine tuning from it. Here in Bulgaria we haven't got public engine tuners and the guys that are from some time in RC aren't talking about what they do to their engines. I would really appreciate some basic tuning princibles some directions where to start from.

Thanks in advance
P.S. A friend of mine is going to chrome it and give it some more life and compression.

I have never used O'Donnell plugs before so how does the ODO77 compare to the MC-59 for how hot it is, on track performance, and how long it lasts? Thanks!

I think they are more comparible to a MC9 which has been the plug of choice for a RTU or if you are running on a track with a long straight with hangin RPM'S

Dennis,

Which top of the line race engine do you feel has the best fuel efficiency? Do you think that that engine could be made more efficient w/o taking away it's power? If the power increased without giving up any efficiency that wouldn't hurt but I don't want to lose any if much of it. Thanks!

YBSLOW, are there any tracks in Az that run the 1/8th scale nitro cars?

thanks

Nope, unfortunately LA or Vegas are about 5 or 6 hours depending on which one you choose and both have really nice tracks. La has really tuff competition and a lot of entrees and well Vegas is Vegas and a pretty cool track with a huge drivers stand.

Thats not too bad...If could, please give me more info on these cars...The cost of them, what brand to buy, about the racetracks, basically anything that would help me get into the 1/8th scale stuff. This could be the next type of car I buy

Either PM me or email me [email protected] and thanks for any help.

Does anyone know why we have a lot of build up ( I guess carbone) on the top of the pistons and heads. I am assuming it is comming from synthetic oil , couse I have never seen this kind of build up from castor oil. We are using O'Donnel racing fuel with 12 % blend of castor and synthetic oils in it. This build up comming out easy even with soft rug (don't need to use sand paper). It is building very fast, let's say 10 tanks and it is there. Any ideas?

Maverick - there is a pretty good group of 1/8th drivers posting to the Oval and Larger Scales forum. They have a 1/8th scale thread going there (although you might need a magnifier to read it. . .heh heh, bad pre-coffee joke!)

Top Gun,
Odonnel seems to be worse about varnish build-up than some of the other fuels, you just have to clean the piston and sleeve more if you don't like the varnish.

Thank you very much for advice. No more O'Donnel. Which one is the best from this point of view?

Since we are talking about fuel... I have been thinking about swutchin from Trinity fuel to Mugen Seike fuel. I have been told that the mugen fuel is one of the best ones around, and while im happy with the trinity I want to give the mugen a try. Any pros or cons?

Thanks,

I've never seen varnish on a motor running Trinity fuel.
