Wondering if you have had any luck yet. I love running them on pressure with a hard tank. I have only used a one ounce tank, though. I have had my best luck letting the engine run long enough to...

I originally thought someone was pulling my leg about the Armor All until I tried it. I had a Norvel Big Mig that wouldn't run out an ounce without leaning and dying. I suspected fuel foaming and...

I just purchased two AR400's for use in 1/2 a IC planes. Haven't used them yet but looking forward to it. I have had exceptionally good luck with all my Spektrum radio gear, even with 1/2a planes.

RE: Some technical Cox 049 questions

Mr. Matthews,

I hope you don't mind but Ipassed this along to another Cox engine user at coxengineforum.com. He had a problem that I thought your post might help him to solve.

Thanks for...

RE: Some technical Cox 049 questions

Yes, you can use both a Tee Dee piston/cylinder and a Killer Bee backplate on a Sure Start. Both should yield a mild increase in performance. But, allCox engines respond to different parts...

RE: How does bottom-hinged aileron affect flying?

Mr. Matthews is absolutely correct. I apologize for the misinformation. Top hinging can be a very good part of differential ailerons though. By making the trailing edge of the wingperpendicular toits...

RE: How does bottom-hinged aileron affect flying?

Many full size planes have the ailerons hinged "on the top" so that the aileron can move farther in the up direction that in the down direction. This can be desirable because when the aileron moves...

RE: A GLH for 2012

How big a prop are you turning? My Norvel .061 AME likes one shim on a Galbreath head/Nelson plug combo too, but I only use 25% and the prop is never any bigger than an APC 5.7 X 3 cut down to 5 X...

RE: A GLH for 2012

I use pressure to help with fuel draw with enlarged intake holes and to help get a staedier needle valve setting through out the engine run.  It also makes fuel tank location less critical.  Pretty...

RE: A GLH for 2012

The picture doesn't explain squat. I definitely prefer the machined cases over the die cast cases. I like to drill through the side of the crank case in one of the spots where it is rounded on the...

RE: A GLH for 2012

No performance benefit. The check valve allows the pressure line to be used as the overflow for filling the tank without also filling the crankcase. I have found that some engines are a little more...

RE: A GLH for 2012

It's a Perry check valve. I got it from Tower Hobbies. Kavan also makes an aluminum check valve that is usually available through Hobby Lobby. Your GLH is really looking great. I am anxious to read...

RE: A GLH for 2012

I like to run the pressure line directly back through the fire wall with a one way check valve then a tee fitting then to the fuel tank. I use the line from the tee fitting for overflow and the check...

RE: A GLH for 2012

I have used the Texas Timer radial mount back plate for a Cox Tee Dee and put about 1/8" of J B Weld in it and then drilled and tapped it for a 4-40 pressure nipple. I J B Welded the nipple in place....

RE: A GLH for 2012

Do you know what kind of boat it was? Was it about 21' long with a fiberglass coated balsa hull? In the late 80's/early 90's the Navy was getting out of the PBR (patrol boat, riverine) game. We were...

RE: Scalpel Flight Video

Looked pretty fast to me. I hope you can get the piston lightened again. It also looked like the engine was really starting to loosen up. All in all, it looks like a great flying plane. I will...

RE: Mini F-16 vintage project consideration

The tap on the plastic venturi body is supposedly the best method, something to do with it being timed to crankshaft rotation,timing I think.  The backplate tap is just simple.  It stays on better...
