The engine is a brand new Randy Smith prepped OS .40FP.  Kind of a strange surging sound.  14 minutes out of 3.5oz of fuel!??

I think your engine was brutally lean.  Never ran a 40 FP, but I would venture a guess that the fuel economy should be at least half that.  The "surging sound" is really sagging.  Hope you didn't cook the engine.

Slow speed flight for competitive CL Carrier planes is done at such a high angle of attack (typically 60 degrees) that it's highly unlikely there is any real airflow over the top of the wing.  The airplane simply flies in a totally stalled attitude and the prop keeps it airborne by modulating the throttle.  Hence, VG's would do nothing but add a small amount of weight to the airplane.  Turn Turn

Hence the Hover vs. Slow flight debate.
Carrier across the pond is still 45 vs. our 60 degree AoA.
They might work better on their models.

Tree Town modelaires is the club name. We fly off of an unused pad at the airport in Sugar Grove.

In the last video you'll notice we have to make 10 laps for points in scale. Fred's tanks were a little small so Chris is topping them off constantly till launch.
The engines when broke in right will start in 3 or less flips but I found out that I got better more consistent runs on 10% nitro and 5-4 black tornado props.
needled up they would do 16'500rpm and run fairly smooth.
harmonics between twin engines made the fuel foam so the tanks are coming of and ballons are replacing them.

If your question is where to find inner tubes that can be used for rubber bands -- go to your nearest bike shop, or the sporting goods section of your local department store.  Get a mountain bike inner tube, and whack sections out of that.

If you go to a bike shop, you may be able to get a junk tube for free if you explain why you want it.

 Thank ya' Tim, I am wanting something that fuel doesn't eat up so dad gum much, I use these sometime to install tanks on profile models.
 The rubber bands just don't last at all.
  Thanks for your help...

Define "real rubber".  Latex?  Neoprene?  Vulcanized?  Not?  Perhaps if you described what you had, what you have, and what you want, then folks would be better equipped to help.

Check with Cox International and Estes Industries before working on molds. The originals may well still exist!

I don't know where the first attempt of this reply went, but here it is again.

9 people flew my PT-19, including at least 5 who had never flown one. One guy started out stating that they don't fly! (He flew it just fine)

In flight order:

Larry Renger
Mike Jones
Bill Byles
Ron Duly
Howard Doering
Chuck Rudner
Rich Von Lopez
Paul Wescott
Leanna Wescott

The photo is of Paul, Leanna and petit moi. (Wescott photo)

Paul and I flew the ET-1s in preparation for next week's EAA Expo at Compton airport. Good thing we did as one model had a bad motor connector!

If you are not familiar with Mike O'Neill's Blog, "FlyBoyz", I can tell you it is worth a look!! Mike is an aviation lover and especially model aviation!! His Blog is very professionally presented and covers a wide range of model aviation.

The link below is about the Ringmaster Fly-A-Thon BUT I also recommend that you browse the whole of FlyBoyz (there are many interesting posts there) and maybe register too so that you will get notices of his new posts. You do NOT have to register to see his posts but you may miss some new ones if you don't.  y1
