RE: AKM SU-27 Flanker-Does Look Good
Before closing up the bottom of the fake jet engine nacells run one of those thin plastic antenna tubes from front to back. be sure to run it through the lightening holes in the "F" formers so it will not contact the spar. I do not know if that spar thing was really the problem... but it would not hurt to keep it away from the aluminum spar!
