I got to fly thw Roo twice today, after the first flight, I noticed fuel on the fuse under the engine again, removed the front cover and this time I was able to pinpoint were the leak was coming from, it came from the propane brass tubing, my fix, I removed the two 3mm festo fittings and added a 4mm fuel line at the brass tubing, flew it again and whala!! no more fuel leak, I'm not sure why they use of two 3mm Festo fittings and a small piece of brass in between.

Anyways, all is really good, had two flights today, AWESOME, AWESOME!!

Moving forward with the next project, most likely the HSD F16.
