Ringmaster w/Fox .35 Stunt and toungue muffler. Origninal Sterling kit. OTS legal. 34.25 oz.
George Aldrich Special (profile Nobler) w/OS .35 FP and toungue muffler. 44.5 oz. (Sorry George...).
This is ready to fly, minus fuel. Are they crazy over-weight? Do I have enough engine on the GA Special?
Newbie modeler wants to know
A tape that Winfred did at the Team Trials was revealing.....almost all interviewed said that their planes were lighter than the scales found them....
Palmer had a shirt "the older I get, the better I used to fly".
Same stuff is true about lap times and weight, I suspect.

The Nobler is pretty much right on compared to what George flew. They fly just fine as light as 36 oz. though hard to get with an FP in it.
The only thing you can do is try it. The overall wing loading is the most important thing. My advise to you is to try it and see how it flies, you will know fairly quickly if it has enough power. You could always change to a 40FP or LA, or a 46LA if your not happy with the power. The mounts will be the same for all of the engines.
The Ringmaster is heavy, mine weighs 26.5oz's but it's from a RSM kit. My bet is it will still fly good.

Prediction: You'll be quite pleased with both.Especially the GA with O.S. 35FP.
Further prediction: If you change to the .40FP,you won't feel any difference.
Can you build either lighter?You bet your bippee(old timer's technical term),but probably not from the average kit.There's an awful lot of both flying happily at greater weights.
Fly'em.Enjoy'em.Try to do better next time.Have fun!!

Your 44 Oz weight is "medium" for a plane with that size wing. If you didn't put a muffler on it, a Fox 35 would be happy with 44 Oz to haul around. In stock condition, operated at its preferred rpm seting, the FP has a 30% (maybe more, probably not less than that) power advantage over the Fox.
Go fly it. The Ringmaster, built from an "average" Sterling kit, was a beefy critter, and 34 Oz wouldn't be completely out of the ballpark, unless you had a 15 on it. Ringmasters don't fly particularly well, in general, but lighter ones in the 24-27 Oz area fly a great deal better.

I'll let you all know how it goes once I hit the skies!
Profile ships frequently weigh as much or even more than a full fuselage version.. If you had a 44 ounce Nobler, you wouldn't be concerned, don't be concerned with the GAS, it will fly just fine.
I'll bet the Ringmaster does well too. Don't forget - it's still only a Ringmaster.

A kit S-1 Ringmaster, with no wood substitution, but a minimalist dope job can come in around 25-26 ounces with a light motor.
On the Nobler, you are in pretty good shape in the mid-40s. In fact, George used to state right here and at Isky's site that he wasn't especially anal about N. weight. Indeed, he mentioned a very "good" N. wt right where you are.
I do realize that most ARF Ns. are coming in below 40 oz. And I have a dessicated swap restoration N. that is around 37 or 38 ounces, and it really flies well. You can do, if you wish, very slow laps in calm conditions with it.
But you should be just fine.

I'll look into the hellium idea as well. At least for the RM.
Actually, helium is not a bad idea, and can be applied with a little extra effort: Trexler Airwheels can be evacuated and pumped full of helium; Pushrod exit can be sealed with a circular bellows-type boot from a retractable ballpoint pen, and leadouts (piano wire type) sealed with telescoping "Goldrod" and shrink tube. Wing is then evacuated by filling thru a small hole with a tapered rubber tip from helium supply hose, whilst inhaling displaced air from a small hole in the opposite end of wing covering. Simply plug the 'inhale' hole with Scotch tape when voice gets PeeWee Hermanish. Worked for me! (in a high sopranic falsetto...)

A few engineers, pretty smart guys, actually bit. They carefully calculated the weight savings, and phoned me (this was pre email) to say it really wasn't worth the effort.
My bogus engineer that proposed this was I. B. Jivin. That was not enough of a clue, either.

Except in some circumstances, I find that engineers are pretty much incapable of viewing the forest for all the trees. O.K. engineers this could be a belated april fools note you know?
Is it, or isn't it? You decide!

As silly as it is, I insist on painting the patches and keeping it looking OK. What you don't see in the pic is all the stains, cracks, patches, repair slop, etc
As long as it looks half way decent from 60+ feet, I'm happy.
