Talking about fuel, I use the Powermaster 20% Nitro and 16% combination of sythetic and caster oils, what is your opinion of this fuel? I have not had any major varnish build up with this type of fuel and seems to run cooler than trinity for me.

Made by Byron, the Mugen fuel runs pretty clean. However for some reason the fuel that escapes the pipe outlet leaves deposits on the outside of the pipe. So now instead of cleaning up stuff on the inside of my motor, I'm polishing the pipe more often.

The O'Donnell seems to have great horsepower, but I noticed more deposits using it. I've heard O'Donnell is pure synthetic, no castor oil.

I've been using BK Racing fuel for 2 years now and sell it at my off-road track and it has been the best fuel I have used in 13 years of Nitro . I recently was racing my 1/8th buggy and my pipe came loose but I stood a chance for the bump-up if I stayed out racing so I went for it. Well , lets say that my engine temped 457 deg. F after the race !!! The best part is it did not hurt my Nova 4 port CLB, it still has gobs of "pinch" and there were no abnormal marks, scars or deposits inside my engine afterwards ! That goes to show how a good oil package can save a "dummy" like me who will keep running even though it could kill the engine.

Dennis, could I ask you something? Can over-shimming the head cause extra heat? I added .2mm to a new TOP .12, hoping to get a few more RPM's on the straight away at Revelation. I was thinking the extra shims would also help with over rev protection My engine still sounded rich with plenty of smoke, but temps were around 300 deg. though. I'm using 30 percent, and geared 17/22 with the stock spurs, tires at 61mm. Thanks in advance for any info.

Sounds like the squish band clearance is too "fat" now and the heat transfers to slow.

Then again what do I know Kev.

Kevin you have mail.
This is a recent common occurance. After you read my PM you will understand what I believe is the issue. Brad and I are struggling with this to as of late. I barbecued a new engine last race. We have a handle on it I believe we just need the right parts.


The serios run pretty good for the price however I hear many guys are using novarossi carbs on them.

Hello Richey. Can you tell me please, what do you think about AAC sets, they are supposed to be running much cooler and can be run leaner, specialy during the summer.

777: I thought the Sirio's needed to be run cooler because the AAC is more easily distorted from excess heat.

From what I belive (and my expirience)-AAC are running much cooler and I have never seen any distortion from the heat (unless negligence). I can't say anything about the Sirio, I have never work with them, may be there is something else beside AAC, which doesn't like overheating, I don't know. What I saw how the boat was running with pluged cooling system on the 30 minuts hit (last 5 minuts cooling system didn't work) and it didn't coocked at all.
It is actualy depend what kind of material use for sleeve and piston. If it is right set up of materials, tapering on the sleeve and piston done right and timing choosen correct for particular aplication-it must work much easier then even BRB-Al set up.
On Control Line team racing in Airmodeling just because of AAC now they are able to run that fast what they do today. Before AAC was implemented there-they had a lot of problem with overheating (actualy they are running on leaner side of tunning). This is why I ask people what they think about AAC.
Any way, thank you very much for your input.
