RE: Sig Somethin Extra?
yes I have one,and love it.
It will torgue roll well.I did make some mods to help it into the 3D world.
Satio 72 W/14-4 zinger,20/20 morgan pattern pro,CF landing gear(needs for prop clearance for ANY prop12" or more)and saves weight.
I'm using hs-225bb's servos on all flight surfaces and an hs-85mg on throtle,battery pack is a 5 cell 650mah nimh pack the car guys use 2.3 oz. at 6 volt.Can't get much lighter than that,esp. for $24.95.
I added 1 1/4" to the rudder(along hing line,not to the top) and added 1/2" to the elevators(again along the hinge line).
The push rods & instructions for the rudder and elevator are WRONG and the rods bind!
I just ran solid wire thru the existing tubes,soldered clevis at servo,and threaded plastic clevisat control horn
very solid feel.
I don't have pants or a spinner on it and it weighs 4lbs 14oz.
good luck in your decision making.
