I have done the second part of the foam hacking, moving the leads in the wings to line up with the larger holes I made in the top of the fuz which I showed previously. See photo here of the wing mods. This is so that I can use extension leads from the fuz, connect them outside it and push them inside before fixing the wings in position, as suggested by Ron Gray. I should be able to try it at the field later this week if the fine, calm weather promised for the West Midlands does come.
Have not worked out a way to use multi-plugs. It would be good but I think might need too much foam cutting. Aidan, what was required on the "giant carbon Z t28 Trojan"?
