Hi Bipe, good to see you back here again.
Once you get past 1/4 scale it's A good idea to go over to gas anyway. Depending on the plane I go right to gas at 1/4 scale without another thought.
I only have one friend that has the CCRC and so far not enough time on it to make A call yet. I went to RCS and Brison when I got into gas for the first time but there is A lot of new stuff being shipped from China that I haven't even seen yet.
You may want to look over at the Gas Engine Forum and see what is going on and get some real informed information from A lot of people that are using that engine right now.
