I have seen the installation on a RV4 and look very good. OK not as low drag as the NACA so you have to accept 0.01 knots penalty.

These were one of a handful of parts the were backorder on my original shipment. I can tell you the consensus is the they are pretty much garbage. In fact many builders have offered to send me their vents gratis! Usually a very bad sign... My understanding is that Spruce has these vents if you are dead set at repair and not replacement. Best to buy a few. They break often. Tailwinds Brian S A276 Tri Gear.

Parigoris" Subject: Re: Europa-List: Tailplane TP12 Drive Plates Becoming Loose --> Europa-List message posted by: "Ronald J. Parigoris" Hello Tony My kit A-265 came with 3/8 pins. Very poor fit, pins fell through the trilobal holes.Factory sent me 10MM special pins and a 10MM Reamer. The fit is still too loose after i reamed holes, but bearly within tolerance. Too loose for me on a new build, you know things will loosen up. The reamer cut a bit oversized, and the pins were not exact the same. I broke down and purchased a reamers next size up from 10MM from mcmaster carr, and some precision go/no go gauges (~2$ ea.). I will ream the hole on my Bridgeport, then measure exact size. then i purchased some free machining stainless from them and will make some new pins with a .00075" interference fit. I will lap to exact size. What I am also going to do is take a popsicle stick with some sandpaper bonded onto it, and make a dog bone between contact areas and also lead in so the hole does not get hurt as much without. To me worth effort now that i can more easily get to stuff before top goes on, compared to doing later. Probably will do the deed within the next month or 2. If you reamed holes with the 3/8 reamer, if they seem pretty round, you could probably force the next size and maybe 2 go/no go through it (increment it .001) could not do that.

In my naivity, I'm sitting w/ a pair of the 3/8" pins thinking that I simply would have to upsize the 1/4" holes w/ a simple drill and that would be that. Anyone out there: How have you handled the TP12 mod?

The mere smallest amount of "out of round" with the hole through the torque tube will create the dreaded movement, exacerbated at the trailing edge of the tailplane. I don't want mine to ever move, so I have had a machinist do the work, precisely. Its a hard job even for him, to get everything all lined up and clamped. Don't do it yourself. If you do I reckon sure as eggs you'll be buying a new torque tube next. I am even thinking of Bob Harrisons clamps, just in case. Pity they are so expensive.

Thanks much for the head's up Tony, Indeed I have such a luxury...but would not have thought to do so without your response. Fred A194
