Yeh last weekend, got 10 tanks through it, its got some pep! It was a bit of a bitch to get started the first time to break it in, but once I got the initial break in out of the way and finished with the rest of the fun the engine runs fine. My old STS/HPI .12XS was a bit easier to break in, but the OS is a bit more stable it seems.

I also bought a STS D3R 3 port modified motor to use in some series races I am going to try and run (3 port only rules for the series)

just to give credit to this os tr...last weekend was the 2nd race for this tr...and the results were still something like a dream to me....i got 3rd A main...it was real hard for me to qualify, only in the last heat i was able to put myself into the A main group..qualified 9th...

although it was my 3rd time qualifying in A, i didn't had any high hopes , maybe just to finish the race one or 2 placing better than i started, especially with the other regular A main faces and mostly italian power plant...

besides the reliablity and competitive power by the tr...the pit and driving strategy also help achieve the good results....my plans were simple , a 6 min. 30 second per refuling time, start last following the rest of the pack...after the 1st refuel i heard the announcement that i was 2nd trailing 1 laps behind the leader...as the race went on i was switching places 2 and 3rd...at one time i drop to 4th..halfway through i was thinking 'this time i can do it at least nd or 3rd...i just have to keep focus and do not overconfident...and the race ended and i felt so good.... anyway now i have more confidence in future races....tq

Does any one run the McCoy MC-59 with the 12TR?

Is it to hot of a plug?

if you do you have to add another washer for the glow plug since is a bit longer than the OS plug!

mc59 is a hot plug

the OS A3 ran great on my OS TR with 30% fuel

Hi guys,

I don't really have a problem but a slight worry about my engine temps. I have an OS 12 TR(P)T 5port.

I run it as rich as possible, any richer and it dies the moment I throttle it. But the temp is still around ~135celcius.(taken at glow plug area) Ambient temp is around 33celcius. It runs fine and has decent power. I can lean it somemore coz I tried it before and there's still some power to be tapped.

But I'm worried about the engine temp. Anyone out there with this engine can give me some readings on their engine temp?

I'm also contemplating putting on a larger head. Any company out there makes a large head that fits the OS?

Cheers...

os engines love to run hot

try a hot plug like a p6

Darth Vader

Wouldn't a hot plug make it run hotter? Or is it the other way round?

I'm already using the No. 6 plug. Running 25% fuel with around 0.5mm clearance.

Comments?

from my experience hotter plugs allow you to run richer and cold plugs allow you to run leaner
