I thought I would post my mod pics. The last UCanDo I had siphoned like crazy with the tank so much higher than the carb. This is a little more like it.

I found that from time to time, I would have to start the plane inverted anyways - I think that was simply because the engine was inverted and the glow plug didn't like that. At least I didn't have the fuel siphoning though. Usually my first start of the day would go just fine, but subsequent flights required inverting to start.

AIRCRAFT: U-Can-Do .46
ENGINE: Magnum XL70 4 stroke
