Quick questions to answer! Please...

Question:

1. Can you tie the 2 (Yellow) Rotax Ing. kill wires together and into 1 switch?

2. If so does it have to be the key style switch?

3. Are is it better to have 2 switches (with each being on it's own circuit)?

Thank you!

1. No it would defeat the purpose of dual ignition and you would not be able to check both ignitions before flight if all goes to one switch

2. No

3. Use two toogle switches, and run the yellow wires from the engine ( one to each switch ) then run a ground from the switch to the frame, and ALSO very important, a second ground straight back to the engine.

Simple and easy.

#3 Is the way I have always had mine done but I wanted to make it easier, thats all.

Part of your regular preflight checks should be to turn off and then back on each of your two ignition systems independently. You should notice a drop in RPM as you turn each ignition system off, and a corresponding increase in RPM as you turn it back on. This verifies that both systems are indeed working.

Has anyone make their own pitot tube?
If so out of what Alum. tubing?

[scottessex]

1/4" aluminum tubing works fine.

scottessex :
Thanks you! Thought it might work. Got that bird feeling better yet?:boink:

Hey I was reading that you have to use studs and nuts on the Exhaust manf. now.

You can't use the allen head bolt that come with the rotex motor?

:noidea:

Here is a link to the style I'm using on the Rotor Scooter, putting it near the rotor head due to being a tractor gyro.

You can drill the allen head bolts and wire lock them. saves them goin into the prop

[Dirtydog]

Thanks I will exp. with some ideas!

Can you extend the leads on a tiny tach with out sending it back into the manf?:noidea:

Some people have done it but the manufacturer recommends sending it back. I sent mine back and they added 2-3 feet.

I found some brake line that had the same fitting as required by the airspeed indicator. It works just fine, and though I didn't have need, the thin-wall steel tubing will bend anywhere you want it to go easily.

Timchick :

How much did it cost you?
What was the turn a round time?

[Dirtydog]

jcarleto :
I know that the Static air tube is not like the Pitot tube where it is open at the end. So I thought beings it was Alum. I could just weld it up with the mig welder I have at the shop here. Then just take a real small drill bit and drill the hole on the side.

1/4" O.D. Alum tubing should be ok right?
Same thing use on the pitot tube kit that I got.

[jcarleto]

Sure...but it is more likely you'll need a bit of static "plumbing" if you have more than one instrument that requires static pressure...a vertical climb indicator, for example. Best to tie them to one source. Not imperative, but that is standard procedure.

jcarleto : Thanks for the input.

I was hoping for a few pic's that someone might want to throw in there that they made. Just a thought! this place has been slowed down since the warm weather came around.

I just used an aluminum tube mounted to the front of the gyro.
Then connected it to the airspeed indicator with a piece of 1/4 fuel line.

the static port is open to the inside of the pod. seems to work great. I have not tested it extensively with GPS comparison or anything.
