I'm currently buildind a Sig Somethin' Extra and I'd like some advice from anyone who's built one or who can give me an engineer's perspective...
1. The plug in wings are quite sturdy (sheeted D-box) but with the double ply sandwich root rib they seem a little heavy. Is this doubling of heavy ply in the root overkill, and would it hurt if I made some (strategic) lightening holes in one or both?
2. Should the firewall (bulkhead) be set back a little to accomodate a longer saito 56 4-stroke?
3. Can two servos be put down the tail for rudder & elevator if the plane is building nose heavy? (I'm doing built-up tail feathers and ailerons instead of the stock slabs of balsa, so it should build out a little nose heavy)
Any advice on these questions will be greatly appreciated...thanks in advance
