I am building this plane myself now..have had a few of the problems you had such as the blind nuts for the motor mounts not aligning and the engine not fitting in them...this is the first plane i have built and have had plent of issues along the way as the directions are about useless..i am almost finished but one thing i was wondering was with the servo install for the wing..did ya have to notch out for the servo wire..even after cutting it out it doesnt quite fit...thanks for the info.
