For long engine life, you need to run the tempature hot enough to boil off any water in the oil. What kills an engine is when the water and byproducts of...
Thought about it, but as Jim Lewis posted I think it is accurate just based on how the case feels (can't touch it) after a flight. I think I need an oil...
Also, just for info, water boils at 212 F at sea level. (and assuming standard atmospheric pressure. At higher altitudes (lower atmospheric pressures) the...
Just read my own post and had a further thought: Water will evaporate at just about any temperature, but heat will help the process along. Yes I really need...
All, 1) What tubing size and thickness are people using for the seat rails, similar to Jim Clement's? 2) Does anyone know how I might bend 3/4 4130 to form...
I just read the article on the Wankel/rotary engine in Sport Aviation. Rather interesting. I think it may be something I would like to look into further when...
Rick, Hang on to the G I may need it for parts. The real reason not to use an 0-290 is that Lyc has declaired it an obsolete model so no one supports it. To...
Steve, while I am very enthusiastic about the rotary for the Tailwind, it is not yet ready for prime time. I think it is about one year away. Mostly we...
Thanks for the input Jerry! It will be a least a year before I am ready for an engine. btw, tell me again how much for the back issues of making the...
Steve, the back issues cost the same as the current issue which is $4.00 per copy. The sheet metal flap/ailerons were covered in two issues #3 & # 4....
John, Seats are plenty strong using 5/8 or 3/4 .035. as for bending 4130 tubing, weld a plate on one end and pack the tube with dry sand. Weld or braze a plate...
I went down to one of the largest and best known engine builders in the Los Angeles area to find an 0320. I said i would like the low compression motor so i...
I am not aware of any curved tubes in a conical mount engine mount. If you are building a dynafocal mount you are better off buying a ring or at least a kit...
You know....... I got to thinking about this and I don't believe there is a tube that goes between the two top motor mount points on the Conical setup. That...
I flew several of these engines many years ago. With the cut down metal props commonly used in those days they seemed to run rougher than the D engines. I have...
I have a late 50's Sport Av which shows pictures of the 0 320 conical mount on Wittmans N374. I am resonably sure there are no curved tubes. Will dig this out...
Seriously... The 0-290 series is just not worth persuing. ONLY if your budget is soo very small AND you have tons of time to scrounge for parts. Even the...
I have a conical mount O-360 on my Cougar. All the tubes are straight. Tubes come off the two top mounts and meet at an angle dirrectly above the vacuum pump...
Gary, this is an 'old mechanic tale'. There is nothing wrong with using autogas in an O-320, or any other low compression engine. Actually, the lead in 100 LL...
Might try calling Plain Parts 916-655-3100 In Pleasant Grove near SMF north of Sacramento I went down to one of the largest and best known engine builders in...
A posible engine source might be "Bobby's Planes and Parts" 817-682- 4220. He has sold a lot of engines to home builders in Texas. He has been around a long...
Damn fool doesn't know what the rel world is all about. I have used nothing but car gas in all my airplanes since 1975. I have run 2 of them to runout time,...
Gary: Everything you ever wanted to know about auto fuel in aircraft but was afraid to ask is found on this web site: http://www.eaa.org/education/fuel/ ...
For all that have responded, I have seen all of the tailwind engine mounts and also the conical mount Van uses. His has a large radiused bent 3/4-.049 tube...
John: now that I know exactly what you're trying to do, this tube can be easily bent by heating as described before. It is not necessary to fill it with sand....
Has anyone put the diagonal bracing on the bottom for the conical mounts. I've seen this done for the 320 with dynafocal mounts (TWT issue 2, 2000) but not...
John: You can bend the tube yourself. Get a piece of hardwood, oak, maple, anything but pine, dimensions similar to a 2x4. Drill a 3/4" hole for bending...
This question has been asked many times and has had many different answers, I never really knew for sure but this is it. We are converting my first TW from...
