View Full Version : Traveler........that is it!! That will be its name!

I now have a name, it will be called "Traveler". Corny huh, but I like it. Anyways tonight I managed to do almost all the wiring and tested it, worked and I couldn't believe it. The load meter shows less than 7 amps with everything turned on and the transmit key held on the radio. Now in normal flight only one fuel pump will be running but two on takeoff and landings so most of the time the amps should be below 5 while flying. I even labeled all the switches and breakers tonight. Looks ok, not a show piece but ok still the same. I also put pictures on tonights page showing the new mod to the nose gear, it also turned out ok.

Well, I got quite abit done today!! I even ran the engine for a bit. Check it out at www.skyguynca.com/tractorgyro/day17.html

That is an interesting gyro.... I will have to spend more time on you website.
I love the building stuff. Keep up the good work.
What blades will you be using? What do you expect the gross weight to be?
05-14-2005, 05:12 AM
I am going to use 26ft Dragon Wings and the gross should be aroun 680
I have been following your progress with great interest. Really a good looking project! :) :)
I notice too, that on day 13 you made a aluminum oil injection tank. As you seem to know quite a lot about 2 stroke Rotaxes, I have this question for you: What is best, oil injection or mixing the oil in with the gas? My Rotax has an oil injection system, but folks advised me against using it. They say that it can give trouble and the engine may seize. :confused:
As I still have to run it, I have not made up my mind about oil injection or mixing the oil and fuel. What is your take on this?
05-19-2005, 11:06 AM
I have done both. I originally believed the stories of seizures when using oil injection. Further investigation showed that the seizures were due to oil starvation but it was from bad preventive maintenance (not changing bad lines, neglect and bad rigging) or inadequate oil in the tank or even using cheap no name oil. I like it because the engine uses less oil and I have had cleaner cylinders and pistons with the injection. I have a few friends also using oil injection in 503's and 582's with no problems, one even has 1400 hrs on his 582 using nothing but oil injection.

Just a FYI< Mikuni, and Hitachi wouldn't let rotax use thier carburators, or ignition systems on aircraft. (liability issues) But the oil injection pump is made by Mikuni, aparently they are satisfied with its reliability.
Thanks for your answers!
In case I hijacked this thread with my question, let me tell all that Dave's site that is updated almost daily is worth looking at. http://www.skyguynca.com Go to "traveller" I go to it daily and learn almost every day something.

Well looking at my tail design and working a few more things out I have decided to change it a bit. It will still be a twin tail but I do believe I am going to make it out of aluminum ribs and spar and aluminum skin. It will still have to be light but I am hopeing the new tail design will let me get away from using struts or wires for the tail section all together and there for be more streamlined and save a few extra hp. We will see........no work done on it lately just alot of thinking. I have decided on the final design for the control system, I have to thank Ken Rehler for his help with this one. I borrowed, copied...what ever you want to call it from his control system on the nifty twin tailed 912 powered gyro. His cyclic control system will fit nicely into my airframe with no changes.......THANKS KEN !!!!!!!!!!!!!!

David, you're very welcome. It looks complicated, but it has worked great for me:

Wow, Ken. That's one beautiful piece of engineering. Did you lathe the radial flanges (inside the bellcranks) or are they existing items?
05-29-2005, 12:19 PM
I assume you are referring to the spacers between the bellcranks and the vertical side plates. They are simple small stainless steel spacer tubes that go against oilite bronze flange bushings which are set into the block plates and similar bushings set in the center block of aluminum.
