Hey I would like to as a few question.
I had knew that An Old Rs42 Cant sit pretty well on a 5port Engine .12.
So well i guess can anybody recomend a good 3port Engine ?

RBx12 any good ?

Bounty Hunter

Well I guess it really depends on what you are trying to do with this engine? If you want a all around good engine that will give you good power results as well as good mileage and is dependable and does not cost that much. If that is what you are looking for then I suggest the Triinity Sirio TRP 3 Port. I have had this motor running as my main powerplant in my Kyosho V One RR for 4 months now. I have put almost 3 gallons a fuel and it is still running clean and strong. This motor will keep up sith any MT/MR12 out there if properly tuned. I have consistenly gotten 6+ minute tanks and plenty of mid-range and top end power. The only complaint, if you will, that I have about the motor is the length of time it took to break in the motor. Even after 8 tanks on the breakin, the motor ran fine but really did not show its true colors until I got an entire gallon through it. Then the motor came alive at race temps. Anyways all of this is just my experience and opinon.

Sirio i ever tought of buying that..
but my friends said that engine overheat easily is it true ?
How was it compare to an OS12TR or RBX12 ?

Bounty Hunter

Well you can get any engine to overheat. The tuning will control that. I think that for the money you spend, running 30% nitro and a med cold plug, you get some good performance out of this motor. Now realize that I have only used one of these and there may be some bad experiences out there. But as for mine, well I cant say that I have won any events, but hopefully that darn pesky item of a driver will shape up soon!

Now I also have to add to this that the motor really did not show its true colors until I have over a gallon through it, running the proper pipe, getting race temps (260+), its not a clear cut process but I was able to get it to perform for me.

Bounty Hunter

Not as far as the OS and the RB, I think they are good motors in their own right. I think that they both are a little pricy. You can get either of them to perform, it just depends on your setup, track situation, and patience with it.

Sirio 5-port turbo.....mid range is sealed off frm supplier so no need to adjust cos it has been bench tuned...

Dont think so..

Just seem like they like to run cooler than the others.
At least in my experience with the .21s, they do.
I would say about between 215 to 220 ...

By the way, I agree with Bounty Hunter that
when the motor over heats ; it just means
its too lean. ...

Bounty Hunter

Is that you RON C? Haha!!! This is Vince. How is the Avance running? Caesar told me that you were posting here on RCtech I just did not know your username! Are you racing Airtronics? I will be there for Nitro Sedan and possible GTP Electric. Just Wanna Finish..... More like finishing in the top 3!

Hey,

What a small world we really live in..
How are you doing Vince?
Yeah, I will be racing the Airtronics but unfortunately
do not think I can do both 2 days of qualifying since I
just started on an out of town assignment.

But I will surely see you overthere on Saturday.
Are you guys ready? Its 2 more days from now
and counting. IT SHOULD BE A LOT OF FUN!

How's your new Mrx doing? Haven't seen you run
it yet.?

Ron C.

Yup, Just Wanna Finish ..

Lately, that's the more important thing
for me to do..

So far, my luck has taught me that
its been useless to be fast if
you cant finish the race..
