Thanks for the info Bo. As I suspected, these old birds, once equipped with modern gear, are really something without having to haul around a pound of NiCads.
That's interesting you enlarged the rudder some. With my extended wing that's something I'll definitely be doing also.
Sheeting the outer wing panels seems to be a smart mod. It's no good to have a nice clean airfoil all along the center panels & then a thinner saggy poor excuse for an airfoil out at the tip. It's no wonder the stock Spectra is known for tip stalling. Hopefully I've addressed that with my half-ribs. Not quite as slick as sheeting but fingers crossed it's a workable alternative.
Appreciate the setup info, thanks again.
