OS Speed T1202
 

Hopefully the port changes will help the fuel economy of the engine. I always found my T1201 very thirsty.

+1

Just received my T1202. I'm hoping that is the case with fuel consumption. Unfortunately, our next race isn't until Nov 6th so I won't have a report until then.

Has it got Ceramic Bearing?

Didn't actually see it but the parts diagram has it labeled as ceramic.

I know some one that is runing one at the Nats next week. I will have his feedback soon.

The engine was very fast at the WC in Gubbio this year but to make 5 minutes in qualification the engines looked to be running very lean but the engine seemed to take it well all week long.

How did it go?

Yes, the bearing is ceramic!

Can you tell us how the fuel consumption was? ;)

Engine has just about a gallon through the motor. I was able to make at least 5 min using 16% nitro with 9% oil. Temps in the 240-250s. Much better than the T1201.

Motor runs strong and has plenty of power. The run time seems good also.

Any updates on this engine? How's run time, power and reliability?

It's proving to be a very quick engine at my local track but the guys are having to run them really really lean to get a full 5 minutes qualifier in.

Looking for .12 engine for upcoming season. I need a honest opinion on the OS 1202?

Fastest .12 I have ever seen.

Its a super slow motor. You dont want it. Its so slow tbat i just bought another one ��

I dont have a problem making 5 min easily. I am using 16% though. I had reservations about using 16% but now couldnt be happier.

Had anyone ordered from eBay. Japan seller. Much cheaper then 500

There are not too many places that I have found in the states that is selling this motor, but I am able to get my hands on the T1201 at a reasonable rate. Is there much different between the motors? I would like to get a new motor as soon as possible.

Stick with the T1202. Has much better fuel economy. Order it from overseas. With shipping, its still considerably cheaper.

Who has them overseas?

I have bought mine on ebay from Hong Kong seller. It was cheaper even including tax duties than buying in Europe.

how you doing with this motor, do you buy it again ?

Motor is super fast. I like it very much. I would like my skills to much its power :) I hope that on coming season I will finally cope with setup for my old car and will use full potential of this engine.

Nice to hear....

What is the nitro per on the stock head (.25) clearance?

I use stock setup with 16% nitro and 1070SC muffler. Still struggling to achieve 5 minutes of driving @ 120 C (celsius). Run out at 4.40... middle size track, 27 ambient temp, RP6 plug. It is fast like hell but drinks alike...

I add a .10 shim when I run 25%. I made 5 1/2 minutes of run time on a huge track, with temps at 260 degrees!! Was on the hottest weekend of the year here in Texas..

My OS 1202
 

The engine was a beast at the GLC this pass weekend. But it lived a short life. I thought the engine sucked the glow plug element into the engine but after a closer look at home the evidence shows the piston pin c-clip became dislodged while the engine was running.https://cimg5.ibsrv.net/gimg/www.rct...5339f6109b.jpg

The c-clip on the other side was still intact

Mines ran great all week. Fastest .12 I've ever driven!!!! I put a lot of laps on it and still perfect!

:cry:Mine ran great until the last lap of Q2. Lol.. This was the first race for this engine:cry::cry::cry:

2.5 - high
Flush - low

Damn E - that's too bad.

No worries Rick V at Horizon hobbies took care of me.

what's a good operating temp for the T1203 - I saw 267 above, i was told that's too high for these engines.

267 should be good. 290 + may shorten the life. Mine ran beautiful at 273 degrees

Thanks E.
