Wow! That is light!
Hey BadBill, as has been discussed earlier, it sounds like there might be some really light airframes out there. If you had my airframe and your equipment your plane would weigh a minimum of 1/2 lb more than it does. If you're not using 1 oz servos, then you can add to that. Or you can look at it the other way, and if I had one of the light airframes mine would be at about 4 lbs 2oz, which would probably give it all the vertical it needs with the GP 42. Wanna trade? :-)
