The mini scout can be a very forgiving flyer. Having built two, I would say aim to build it light and fly maybe on 2S - the added weight and power of a 3S battery will make it fast and carry lots of momentum which will make crashes a bit more consequential.
It is a fun model - when I wrote off my first one, I wanted to build another one immediately, but figured it would be better that I explore other designs. Part of the reason why I jumped on the 2021 Mini Scout challenge and maybe the reason why
@The Hangar chose the Mini Scout to be the model for the ultralight challenge.
When I maidened my first one, I put it in my Dad's hands, forgetting he hadn't flown a fixed wing in ages or done any sim practice. He flew it straight into the ground. The wing and prop snapped and the 'chin' of the fuselage was all bashed in. I glued the wing back on, using some acetate sheets to hold the foam either side of the crack, glued a section of lolly stick to the chin to straighten it out and put a new prop in. It flew like it had never been crashed! I did notice some flexing in later flights, but it was nothing to worry about.
Oh and both of mine have been made from my 6mm Depron, so that combined with all the patches shows it is very accepting of deviations from how FT's own ones were made.
