I have a R Smith aero tiger 36 that I want to bench run some more, and have in mind using an A P C 10.5x4.5 using 10% nitro and 22% all synthetic oil.
Does any one have some other suggestions, and why?
Thanks a lot...

Run it until it snaps back to 4 smartly when you pinch and release the fuel line, then, go fly it. It's the best 4-2 break engine ever made in that size, and the best engine you can have that doesn't require a pipe.

Is this the one I emailed you about? number 155, how many runs on it now? is the rod still stuck at the top? how long has it set un-run, after run oil in it? It uses 20 to 22 % oil max nitro doesn't matter
a 10.44 x 4.5 will be OK , 11 x 4 will too
what is the shape the engine is in ? has it been rebuilt?
If you need a Aero Tiger instruction sheet I can email one to you

The tuned pipe motors like a little more synthetic and I recommend a 15% synthetic, 7% castor blend or a 20% half and half with 1 ounce of Aero-1 fuel supplement. Although many use 1\2 – 1\2 with great success. This works very well in the Precision Aero , OPS and Max VF engines, Super Tigre Thunder Tiger, AERO TIGER and most all of these type engines..
For ABC, AAC ,ABL, ABC-R and ABN motors, start out in a very fast four-cycle and about every 45 seconds; pinch the fuel tube to kick the motor into a momentary two-cycle. These types of engines normally take more break-in time than do their iron lapped piston cousins . If you can run the motor in a fast four-cycle and without touching the needle, pinch the tubing to lean the motor into a two-cycle for 20 seconds or so, then it should go right back to a four. After breaking in the engine with a few tanks of fuel , you can start using the needle to cycle back and forth from 2 to 4 cycle. When it is broke in you should be able to hold a 2 cycle for 30 seconds or so, and come back to a 4 quickly by turning the needle richer . If not, it probably needs more running time.

Hi Randy;
I have a couple of Aero Tiger's tucked away for a rainy day. The next time you are sending things out, would you please email me the instruction sheet? I would like to have it saved on a computer and a thumb drive just for future reference. I hope to build something for them soon, just trying to figger out what I want.
Thanks alot,

Yes Randy, This is the one that we conversed via email, and the wrist pin came loose or I would not have run it, I had it well oiled with marvel air tool oil, and it was loose when I took the back plate off yesterday, so I ran it once with a 10x4 prop.
Thanks for all the advice and help..
