I bought an ASP .91 2 stroke largely due to the attractive price. The problem is that it came with Chinese instructions. Unfortunately, I have not been able to locate any english instructions for it so I am at a loss as to what the appropriate break-in prop size is and after break-in, what the recommended prop range is. Does anyone know what the recommended props are for this engine before and after break-in?

Thanks

Not exactly what you need, Mike; but here are some translated instructions:

Go to the Hobby People site and look up the Magnum 91 4 stroke specs. Same engine.

That is just about the funniest translation I have ever seen. It does however give me one of the recommended prop sizes.

Thank you.

Make sure you are looking at the 2 stroke 91, and not the 4 stroke. I dont know which you have, but they have both been mentioned in this thread.

Yes, thanks. I have the two stroke and that is the Magnum spec sheet I found.

Hi!
Running in is the same for all modern ABN, AAC and ABC engines! Just run it at fairly fast ...not slobbering rich!

For a 15cc engine(.91-.90) use a 14x6 prop for general sport flying. RAM and APC are good. 15x4W and 16x4 for slow flying planes and 13x8 for faster ones.

A good glow plus is the OS 8 or Enya 3 or 4.
Rossi 3, 4 or or Nova Rossi 4, 4A or 5 are also suitable....but there are other plugs equally good.

This is very helpfull information. Thank you very much! I have some 14x6's and 13x8's on order for my P51 Mustang.
