Jim,

Thanks for the messages and for your efforts.

Can anyone submit the engines for approval, or does it have to be the manufacturer/distributor? It may be more expedient to just get a donation of current, new, and never opened engines from a supplier like Tower or a dealer. I would like to see the Chinese made SuperTigre GS-40 considered and added to the list. RCPRO and/or myself may sponsor a batch of engines for consideration. Let me know and I will see what I can do about getting some shipped directly to you from Tower or Hobbico. Could I get the engines back at some point after testing?

I will contact GMS about submitting their engines also. They currently appear to have supply issues. Or maybe Tower just ran out and it is a problem with Tower.

I agree that the TT Pro 40 is a very good engine. I have no problem with them at all. They run well, are easy to maintain, and seem pretty consistent.
