Speculating really goes no where. There will be those that will be first in line and report back with their experience. I will be waiting to see what the reports say. If good, I have some multi-engine projects that can use this engine. I'd like to see a 15cc too.

I had been reading this thread merely from curiosity, but did come across something I hadn't seen yet. I have been in RC for 16 years, most of which dealt with stadium trucks and monster trucks (1/10th and 1/8th scale cars). Just recently I learned of a new 4 wheel drive monster truck from HPI coming with a 15cc Gasoline engine. If there is a 15cc gasoline car engine, an airplane engine in that displacement range can't be too far off. It hasn't been released yet, I believe its due out in the spring of 2013. The cylinder head of the engine looks SuperTigre-ish...
Here's a link to it for those that have any interest.
