Whoopee! Fox is sending me a C/L venturi for my Fox Hawk .60. Will this do the trick for a Super Duper Zilch? As the preacher said at my middle son's wedding...
Hi John, The Fox Hawk will be at least twice as powerful as the O&R .60! You will need to beef up construction, especially in the nose area. And watch your CG,...
Ralph, I would greatly appreciate Biceps data if I can't locate a suitable Kit for Hawk .60. In the 50's I gave my buddy a S/D Zilch for his B'day. He powered...
Maybe that Fox Hawk .60 would be put to best use on that Junior Ringmaster. The above comment was not intended to be cruel or anything of the sort. I just...
Hi John, Do you have broadband connection. I can scan the article and email it to you. If no broadband, send snail-mail address and I'll print it and mail to...
THANKS, Ralph! John V. McCollum 650 Island Ave. Long Island, ME 04050 I'll reimburse postage when I get return address. John [Non-text portions of this message...
I recently retired due to health problems and I am putting the extra time to good use involving my Great Nephews in control line flying. One of the things that...
... Actually, both SIG and Tower sell a similar kit that works vert well. You don't *HAVE TO* run a power panel, but they are convenient, and the mini-panel...
Dennis, I have several kits available that would be ideal for your "beginning-again" project. They are 1/2A's, but as the saying goes, the little engines...
Ray I went to your sight to look over the 1/2A planes that you designed and was really impressed with the fine craftsmanship. We already have a plane to start...
Hi, I have a few RC Engines that are lying around and would like to know if I can get Venturis, etc. for these. Older Webra 6.5, Enya 40X K&B 40 Series 75....
Hi Emile Is there any disadvantage to simply fastening the throttle fully open, with light copper wire or similar, and then treating it as a simple venturi ? ...
Yes, there are a few people who make custom venturis - and (importantly) have an idea what diameter to start with. I highly recommend Scott Riese in Oregon...
http://www.clstunt.com/ This is the "Stuka Stunt Works." They will make a venturi for any engine. [Non-text portions of this message have been removed]...
More accurately, the host - Leonard Neumann - will make one. Nothing personal, but I ended up waiting many weeks for products from him. Perhaps he's not so...
In a message dated 2/8/05 10:44:40 AM Central Standard Time, ... Jim Lee does custom machining and can make you almost any venturi. Just let him know the...
In a message dated 2/8/05 6:01:24 AM Central Standard Time, ... Dennis You may want to look at coroplast for 1/2A models. We have been using it here in Omaha...
Check out: http://www.aeromaniacs.com/Platterins.html They have the "Osborne Platter". I used 4mm coroplast and .049 Baby Bee and Golden Bee for 2 of them...
I have over a dozen motor booklets that came with some of my engine collection. Half say to face the spray bar hole (nozzle) directly opposite flow and half...
Hi John, As usual, "it depends". Experimentation is necessary. Depending on the type of run you want, and the engine/load/prop/fuel, it can vary. There's no...
Ralph, Would the 90 degree to flow be more for speed, while opposite to flow be more for stunt? John [Non-text portions of this message have been removed]...
Really sorry, John - - Experiment, experiment, experiment . . . Ralph ... __________________________________ Do you Yahoo!? The all-new My Yahoo! - Get yours...
Great question but hard to answer easily. Most engines have a "sweet spot" where the spray bar does its best job of pulling fuel from the tank. One speed ...
Hi Bob, Your answer was MUCH better, and more complete, than mine. I had forgotten that the Fox .35 Spray Bar had the holes arranged in a wide "V", although I...
I did the same test once -- set up a venturi with a "u-tube" manometer on the tank side of the spraybar and used compressed air to create flow. The "back and...
I agree with testing different spray bar positions. I use a Bantam .19 on igintion in my Peerless Panther. The engine is a rear rotary valve type. My first...
Quote = "In other words the hole is pointed toward the incoming air flow. " That is strange, it's a position I wouldn't have even tried as normal thinking says...
To me, "away" from flow is the same as opposite from flow. Semantics, semantics, semantics ... Okay, maybe this is better: Hole faces downstream. Lordy, I...
