overheatingi have an os 32 in my wolf and here are a few tips. if you do not have the top cowl with the vents cut out(they should come cut out) cut them out. they look better with the screening and they help with cooling. also the hole on the bottom, it should be lengthwise, long enough to expose the cylinder head to the backplate. the simulated jet intakes are already cut out and should stay that way to aid cooling. as for fuel, i get away burning a synthetic with 15% nitro even on the hottest days. a high headspeed(not too high of course, if i knew what speed i was running on mine i'd tell ya) helps with optimum power and cooling as well. i use an o.s #8, A3, A5 and enya 3 plugs in my birds and get no probs at all. also, the nice thin glass blades seem to help achieve the high head speeds that those little engines seem to be addicted to. you can help with the overheating also by bumping up the nitro content if you are running 15% by going to 30% OR, you could just add more of the oil that you are using. i have tried all or at least one of these methods to get a cooler run. i usually go up in nitro as a last resort because of the expense.
