Spent several hours attempting to correct the bend of the three skylight ribs, per text manual. Apparently I do not have the correct tools or techniques. How does the factory match the airfoil shape? If the factory can’t do it, how can “Joe-bag-o-donuts” like me do it? 😂 Kit #34

The google build photos don’t convey any real information. There is a mention of twist but no instructions. Rigging the flaps section in the paragraph title there is a /Washout. But no instructions about washout. It’s bad enough my aft spar attach point parts do not match the parts manual or text manual. I can not just go ahead and hang the wings and hope for the best. Yes I have read and re-read everything that has been published including the last news letter. This is a crucial point in any aircraft build. Come on guys. Publish some useful information. I don’t want a $100k airplane that flys cock-eyed. Frustrated? yes. B.S. Aeronautical Engineering USAFA, A&P, IA. 30 years building, repairing, and maintaining RVs.

Just started final Titan baffle seal install. Notice in factory pictures most of the baffle seal is attached with baffle seal pop rivets and not using KPPW0343 baffle seal capture strips. Seems if the factory uses baffle seal pop rivets they should be supplied with appropriate supporting documentation. In addition, trying to use straight capture strips cut to small pieces on the curved baffle looks nasty.

It would be helpful to see how the factory installs the Lightspeed ignition firewall forward. Current photos are kinda sketchy on routing from CDI boxes to coils.

Does this look correct? Aft end of T-Bone requires a small bit of trim. Fwd end of T-Bone requires over 1/2 in. All measurements per text manual

So I followed the text and got this. The cowling starts to fit pretty good but the lower cowl does not fair into the spinner. So what’s up with that?

Could someone explain how the baffles and cowling mate? Yes I know the center hole for the prop has not been cut yet. The cowl is centered on the spinner plate.

Sure would be nice to have a picture or two demonstrating how to safety wire the alternate air cable so it stays put. AC 43.13-1B Sec 7-123 does not address this and my 25 years as an A&P leaves me with no experience.

Tried all kinds of combinations routing the high tension ignition leads. Keep coming up with one lead too short. Leads supplied: Two 16 inch Two 20 inch One 22 inch One 26 inch One 32 inch One 36 inch Do I have the correct leads? The side view photos in the support page help a little, but a top view of the Titan would help a lot.

Can not connect the boost pump prefilter with fittings provided. The figure page refers to the pump documentation. Did not receive any. Went to the pump manufacturer ‘s web site. No help. Appears to be a missing fitting.

Checked the alignment of the factory drilled holes on the S-21 seat back frame. One frame was good the other misaligned. Bolted the bad one together just to see what would happen. It was a mess. Checked it out on the drill press. If one where to assume the first bend from the base was inline with the base, clamp it down, then drill, you would end up with exactly what the pictures show. The rod depicts what the pins would look like in the seat track. I know. I tried it. Doesn’t work. Question is, what is the fix?

Not a bad idea. But what exactly do you recommend at Rans? Tried a rattle can brand on a test piece with poor results.

Going through the inventory of the finish and Titan Firewall Kit did not find a master solenoid listed and of course not supplied. I am not familiar how to wire an aircraft electrical system without a master solenoid/contactor. And do not want to invent the wheel again. How about publishing a basic wiring diagram for the Titan. I don’t think the supplied Rotax diagram will work.

Getting ready to paint side skins of boot cowl. Looks like one would need to trim the bottom aft edge if the boot cowl were to be attached after installing main gear for the S-21 tail dragger. Any reason not to?

Recent Kit Planes article stated that the lift strut anti skid tape is no longer needed because the vibration problem has been solved. If true what was the solution?
