Default Just a few questions!

The use of bath room scales is not very accurate, did you weight your 9A this way? I tried to use bath room scales and it didnt work for me, I ended up renting race car scales from Avery tools which worked very well. How much did your nose wheel weight?

Best of luck with this engine installation.

Over the weekend I happened to run into a guy flying with one on a JustAircraft Escapade and it was a very tidy installation.

About the only question I have with the entire installation was the unpainted stainless steel engine mount.

Stainless Steel has many great properties but one of its drawbacks is that it can crack under load and more so when it is vibrating under load. If it were painted white, I would feel better as any crack that does develop would be easier to spot.

Just a thought - would powder coating the mount be an option? Or would that be overkill?

Most engine mounts coming from Vans are powder coated.

John: I'm on a business trip and don't have information with me. I'm going to weight again with racing scales before my DAR inspection.

I used two fat scales (350 lbs.) Walmart-$15.00 and one normal bath scale.

vans will let you order mounts bare, which is what you need to do if you will modify them any (like for a different engine mount) I don't know how jan is doing the mount for the viking/ rv12, but that is what i've seen on an rv7subaru

Past experience with bathroom scales, gave me reason to make sure they are all three the same height. You can put spacers on the low platforms to make the playing field level.
Don't forget to send me your list of conversions items when you get back from your trip Ron.

Ron, I'll be following your progress and future flying reports. The installation looks very clean and neat. I had a 912ULS trashed after 70 hours (not on an RV) because of a failed fitting on the hose to the oil pump. The farmer didn't appreciate me plowing his Soy Bean field early. I'll be looking for something more afordable than the 912ULS when it comes time to replace the engine. At least I have my brothers RV-9A to fly.

Default Viking/Eggenfellner?

Looks like Jan Eggenfellner is the head guy at Viking, or am I wrong? If so, is Viking a separate company... or is it a subsidiary of Eggenfellner engines, the Subaru guru?

Just curious, thasall...

Same guy, different engine offering. Don't know his 'corporate structure'.
