    Horrible news from Vans Aircraft

    I think that if I had assembled a bunch of parts that are showing cracks and I have an engine deposit through Vans and don’t know where that money is now, I would be a little bit more than disheartened

    Belt drive

    Just read about the 1/3 scale B29. Using Honda engines with belt driven reduction. Sounds like a pretty simple solution. Better then a gearbox?

    Engine ideas

    I’ve seen a number of snowmobile to airplane engines, but has anyone tried a PWC engine? Newer ones are all 4 strokes and make up to 300 hp. They also have closed loop cooling systems

    Aeromomentum RV-12

    I can’t seem to find any reports on Aeromomentum fwf from actual end users. It sounds like a great option, but would like to have a report from someone who has flown behind one.

    Comfortlite seat

    The seat itself weighs 5.9 lbs I didn’t weigh the old seat bottom and back but I think I gained maybe a pound or so. The picture shows the seat in the fully back position.
