- Vic from Base Leg Aviation updates us on the RV-10 engine compartment upgrades he is working on. Then he demonstrates the difference between a steel braided rubber hose vs a steel braided teflon hose. He shows how to assemble a teflon hose.
Finally he answers a request from the last video. He shows how to measure resistance (ohms) on the Lightspeed spark plug ignition cable and across the terminals on the Lightspeed coil.

Regarding the resistance checks, “Opened up” would mean infinite resistance (OL on the meter reading), not “no resistance” as stated in the video. Just a mix-up I’m sure, but I thought I’d mention it for the benefit of others watching that may not know the difference. Thanks Vic!
We always pressure tested even when it was just a low pressure line just to be sure. Fire sleeve everything. Peace of mind. When do you suggest replacing or overhauling the oil cooler?
oil cooler should be flushed whenever the engine is changed. Sometimes sooner if it's recommended by the manufacture. Some certified airplanes call for flushing the cooler at 500 hour intervals. I flushed mine whne I changed the engine 1000 hours ago.
Hey I am also using braided teflon everywhere. I was curious why you didn’t wrap them in fire sleeve for under the cowling?
I wrap all fuel lines forward of the firewall with firesleeve. The oil lines are on the back side of the baffling. The one fuel line on top of the engine does not have any fuel in it during normal operation. The fuel lines from the firewall to the pump, pump to fuel servo, and fuel servo to spider are all wrapped in firesleeve.
@@baselegaviation1614 thanks Vic 😁
If you are looking at a SS braided hose in the engine compartment, can you tell if the hose within the braiding is teflon or rubber…maybe by some markings on the fittings?
IF they are made bya certified shop they usually have a tag with a type and date code on them. Otherwise, hopefully the builder made an entry in the logbook.
Is there an easy way to figure out if your existing hoses are rubber versus teflon, since they both look similar from the outside?
I ask, not just for longevity but also for the capability to withstand ethanol in fuel.
Unless there are tags on the hoses or documentation in the logbooks, I'm not sure how to identify the difference. At least I haven't figured it out yet. :)
I am wondering the fire resistance of Teflon vs rubber fuel hoses. I use as much fire resistant items I can,even on zip ties.
This is what I have found: PTFE has higher temperature tolerances than rubber does. Thus if the engine overheats, you have less chance of the heat damaging the hoses. In addition to the high heat tolerance of PTFE, it has a higher pressure rating than rubber. Thus, should one of the systems, such as the cooling system or power steering malfunction in such a way that it causes more pressure than it should, there is less chance of blowing a PTFE hose. Size AN6 is able to handle up to 2,500 psi.
@@baselegaviation1614 Excellent replacement/upgrade, I like how the PTFE fittings work vs rubber.
Now if I could pressure test,with fluid,my custom built hoses to 150psi before use.
Where did you get the new coils?
Dynatek Dual Output Miniature Coil DC11-1 a.co/d/bwbvzTQ. (2 pack). amazon
@@baselegaviation1614 Is that what Klaus is recommending for use with the plasma 3?
Yes. They are the same coils he provides.
