ORIGINAL: jdbeast00

I have tried several times unsuccessfully to break in my engine. I think the model is something similar to TTR40 Thunder Tiger 40 RC Engine...

Basically, what happens is that even though I follow the instructions, the engine always seems to instantly rev up so high that it sounds like it is going to explode. I always end up getting scared and turn it off prematurely. I obviously don't have much experience with R/C stuff, but I have seen others flying their airplanes so I think I know when an engine sounds like it is revving at normal levels versus when it is too high. Anyone have any idea what I'm talking about?

Thanks in advance!

"Beast",

Your engine is an ABC/ABN, tapered-bore type.

The definitive break-in method is described [link=http://www.rcuniverse.com/forum/m_1850473/tm.htm]here[/link].

It must rev pretty high and no damage will result, if you use a properly sized prop (10x6, 9.5x6, 9x6).
