Hello
Thanks for the nice words about my "Panchito" , it is covered with fibreglass 3/4 oz. and Zap finishing epoxy (Very easy to work with) and the aluminium is from Mick Reeves in the UK it is called Metalcoat [link]http://www.mickreevesmodels.co.uk/~mickreev/Access/accessories.htm[/link] it has a very very strong glue on the backside,I have polished it with some stuff called Autosol especially made for aluminium. My rudders and elevators are covered with fabric too it is this [link]http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXB195[/link] it has almost the same colour as the aluminium but on the real plane you can actually see the difference too.
I think the 101 version can easily fly on 20 to 26 cc gas engines I flew mine with two OS 120 Fourstroke Glow engines with pump and it was actually plenty of power but today I would have chosen gas engines too, they are more cheap to run, less oil, and no messing with nitro and so on.
Here is a short video of start up take off and landing great flier this model.
