excuse me to disagree, but a correctly broken in .15 LA is one of the must powerful .15 engine you can find.
the .15LA is the only great engine of the LA serie, it fit the wonder perfectly and you will have unlimited verticals.

As I told u I have several diferent wonder and the most nimble and funy one is the .15 LA build light with 3hs81 servo, a hitec555 receiver, 600Mah battery pack and 4oz tank.

By the way I told u to not overpower your wonder, but I will continue to work on my 32SX powered shrike10 .
