RE: Extreme Flight 88
MikeCam,
I have built quite a few different models and the Extreme Flight Yak 88 is by far the best constructed of any I have worked on. I did quite a bit of measuring and testing to see if the airframe was straight and mine was right on..didn't have to change a thing! I have measured real aircraft that were not as accurate. The instructions are quite good and any questions I have had during the build were either answered right away by EF or on this BB. Sorry to hear about your problem with the cowl blocks, they are fine on both of my Yaks.
