I built a Jetco Sabre Jet and a Nobler.  Wrecked them both and put the two together with the stab and wing placement same as the Nobler but it looked more like the Sabre.  Point is it was the best flying stunt ship ever!  Power was a K&B 35 Green head. 
Won 2nd in Sr Stunt at the 1958 Midwestern States Championships in Kokomo Ind.  1st was the defending Nat Champ and I cant remember his name-flew an Ares. 
That hybrid Sabre would take the wind like no other and I always did better at contests where it was real windy.  I bought a kit a few years ago to try to replicate it but Im just too old to do it now.  Guess Ill sell the kit!

For what it’s worth, I recently inherited a rather large assortment of engines and engine parts, both new and used.
LOTS of other assorted items.
I have no use for them and all monies collected will go to the Border Collie rescue center.
Prices will range from FREE to very reasonable.
Buyers pay shipping costs.
I will be going through them soon.
I will also be listing kit(s), handles, props, electric stuff, MANY PLANS, etc.
Some of the plans: Thunderbird, Nobler, Vector, Chief (both versions), some Randy Smith designs, Sky Writer (Chinese design), Twister (regular and Fancher mod), Legacy, Atom, Airon, Argus and many more. Some free and others very reasonably priced.
I will post a complete list as soon as I inventory them.
Plans will be shipped rolled (EXPENSIVE!) or folded (much cheaper).
Contact me with your needs.

Thanks Doc.

Thanks for responding.  Something is sucking the life out of the batteries and nothing is jumping up saying "Me, Me, Me"!   Since I cannot do anything about the weight (it is now 68oz after changing ESCs), I am stuck trying to stretch available mah. [snip]

I suspect that it is the weight of the airplane and the associated drag from the wing required to support that weight that is sucking the juice out of the batteries.  Lighter plane would need less mAh, but I agree, not much can be done about it right now.  I would then recommend flying on shorter lines.  This translates to less work required to do the flying, and so less mAh.  At this weight, I doubt there will be any problems with line tension.  And you will have an added benefit of having the plane closer to you, which (some reported) somehow makes it easier to nail the bottoms.
Just my $0.02

2 1/2 min. Even then I use full up elevator until the plane gets rolling. The plans generally list the wheel size.
