thanks a lot Charles!
we´re talkin about 2200 kg with the 4T engine! (77,6 oz?) if i´m right
later was electric converted and with engine and battery weight was 2,050kg, wich is still heavy for competition
the owner, Rogerio Fiorotti gave up and keeps the plane just because of the beauty
the final weight was a combination of factors:
the ARF may have some heavyer balsa than expected (not sure now), the design uses a LOT of ribs, too much indeed
a friend of us stripped the covering and assembled the model, he had changed the flaps that came badly sanded and warped for some heavyer stock
i have no idea of what else he may have done that added weight but the flaps are one of, the originals was about 3/16 and he used 1/4 heavy wood
not sure if he replaced anything else. then he or me (really can´t remember) covered the whole fuselage with 3/4 oz fiberglass with finish resin
back then (about 6 years ago) we both used to build F3A and scale big R/C planes and this was the norm for finish.
so this push weight up for sure, then i had the "brilliant" idea to brush the primer instead of spraying, more bad decision....ok, i have sanded a lot the primer but the final outcome was heavy.
learnt the lesson, now that i am fully back to C/L my finish got better and lighter and new materias came to the game...
it´s a learning curve
