Just got my Yak 2/16. Looks good. Need a recommended engine. Understand the DA does not quite have enough oomph. 3W makes a good product, although I do not know which engines have the newer ignition. I have to buy an engine anyways. Some recommendations? Been flying models 5 yrs and pattern 3 years. Been messing with YCD 3D for 3D stuff. Now its time for gas 3D. Is pulling down the weight that critical? I understand higher wing loading means increased speeds, but is it that critical on this type of plane? I really don't want to do a bunch of mods for no reason.
