Yeah, manage to win the championship this year - race class. But this thing is growing fast and I'd like to be there next year too.
http://rotac.ro/standingsWhen I bought the intercooler I've seen a thread with a lot of graphs and tests where this intercooler was clearly superior, can't remember where exactly now, but you can't go wrong with it.
I'm racing with B9 T5 F9, 0 timing retard at 35 degrees Celsius, but I also have extra water and oil coolers.
Unfortunately that link doesn't work now. Lithium batteries have a lot of starting power, their problem is capacity. The best lithium batteries are

I'd recommend something from
