Ok, good thing that I didn't maiden today, the thing that kept me thinking has been resolved, the nose retract kept getting stuck some times in the up position, after talking to a friend and getting some ideas today I found the problem and it got fixed for good by adding two very thing spacers to the retract, the picture explains it better, also I had forgotten to set the throttle fail safe, I prefer to do that at home than at the field and I CG it again but, this time the ECU battery was added and as suspected that was enough to move the CG forward to the 7" mark, I also added a second small air tank to the brakes for more volume and weighted again for a final dry weight of 22,5 lbs.
Some pictures of it on the ground, I think it looks awesome.
