How to remove the pin and open the canopy is part of my passenger briefing.

Your cylinders are covered by the silver metal held together with wire. Why!? That's not the VW super-tin, and you are blocking all the air flow to the cylinders. I would have to say THAT is why you are running hot. This is the the standard Revmaster shrouding, it wraps around the barrels and heads...

As others have suggested, you can run it to get it warm and see if it improves. Check the rocker arm clearances to make sure a valve isn't being held open. Is the air escaping through the carb (intake valve) or the exhaust pipe (exhaust valve)? If you have a borescope you can have a look at the valv...

I am amazed by the amount the gear legs flexed and sprung back. I guess that's why Monnett went with titanium. Last year (2022) when I landed at Airventure on 36 with a very stiff left cross wind (I'm a tail dragger), after touchdown the wind heeled the Sonex so far onto the right gear that I was s...

Yikes! Glad it was only metal and not bone that got hammered. We've enjoyed your participation, and living vicariously on your trips. I'm a year into building an RV-7, but still flying (for 9 years+) my Sonex, and will be for the next few years. I'll likely also still hang out on the forum even afte...

Thanks. I had 1/3 of it done for months, and finally figured I should finish it before Airventure 2023 :-)

The VW is not a tight tolerance engine. I almost never get good values on a leak down test when the engine is cold, though I do still test it that way to start. Then I go fly in the pattern for a few circuits and come back to do the test. The numbers have always been well within the 70's, and someti...
