As a multiple builder I find the RV14 a very interesting project. The manual is well thought out and as long as you go step by step, everything works well. There have been a few wow moments, and the flap system was one of those. There are no "cutting and shimming of plastic bearing blocks as in other models. In fact, the precision fit of the flap drive is nothing short of amazing. This was a parts kit, meaning that I built the fuselage without a jig, as per plans.
The flap drive parts need to have a couple holes drilled and the supplied template/drilling guide makes this simple and accurate. The flap bushings are pre drilled and bolted permantly in place prior to fitting the actual flap drive parts.
The "Ah" moment happens when you slide the flap drive tubes into the plastic bushings and they mate perfectly in the middle with no slop, no adjustments, and have a smooth movement. A light film of grease, as per directions, is all that is required for this faultless fit.
These are the things that can only appreciated when you have built older kit models.
