My .46 LA is in a Sig Kadet MkII trainer. It has plenty of power for that plane. My brother has one in a SPAD Debonair trainer. Power is only "adequate" for the SPAD, but it still flies OK.

I've heard of the Acro Wot, but am not really familiar with it. I don't think they've really made it to the US. Depending on the weight, I'm sure the LA will work. Try taking the baffle out and see how it affects the RPM. You will have to readjust the needle setting.
