Default moving the firewall back on a CG Ultimate..?

Robelander, interesting mods. Dito on the tri stock for cabane mounting. I also added 1/32 ply on each side of the screw pad.

I hope your all-up weight is not too high. I'm thinking of starting another but going the ultra-light route. I would like it to be no more than 7 lb with a 90 four stroke. That suits my close-in slow flying style. I would actually be removing more wood from the structure. One possibility is an all balsa fuselage (truss frame style). I think I could get away with fewer ribs and wider spacing on the wing. The tail sheeting was very heavy in my kit. I would go 4-6 lb contest grade balsa for this project. I would change the gear and lower wing mounting too. All that hardwood adds a lot of weight. Maybe some carbon doublers in key areas.
