C-150 Exhaust

[Joel]

Is there an STC or is it a field approval for the C150 exhaust installation? If an STC who owns it?

Thanks

Terry does the Luscombe exhaust, I did a field approval for the Cessna 150. Tim

There's one here for the F-19 (http://www.taylorcraft.org/resources.html). I have a set F/A on my BC12D-4-85 as well. Depending on cowl and header shape they may or may not need a cowl bump (mine doesn't due to re-shaped header pipes). Charly Center has made bumps before (http://www.crosswindsstol.com). Edit: See an example of cowl bumps in last picture under "Photos > Builds".

Tim I remember looking at the Hanlin walker exhaust when i did my c85 there are two one is the Cessna and the other is Aeronca I think the Aeronca fits tighter to the engine and is the one that does not need the cowl bumps.I did the luscombe with Terrys paper work

Re: C-150 Exhaust

Thanks Gary. That is great. I was hoping for a field approval. I have a good FSDO I deal with. They have been reasonable on the field approvals that have already been done somewhere else and make sense with existing parts.

Re: C-150 Exhaust

I expect the C-150 conversion improves exhaust tuning, flow, and certainly better heat for the cockpit and carb than the original designs. With some field engineering I've added a second cockpit defroster heat valve and long hand-held SCAT hose to clear the windows of frost in winter.

Re: C-150 Exhaust

Gary would you just lay the SCAT tube up on top pointing at the windshield?

Re: C-150 Exhaust

Yes that works. I have a hose clamp over the hose and piece of metal for a hook attached to it to temporarily hold the end of the hose on the V-tubing over the panel near the windshield. There's also a need for defogging/frosting the side windows as I have clear Lexan covered doors so I move the hose around some.

Atlee Dodge makes a defroster kit I've had in a few planes that provides a firewall heat valve with two fixed 1" outlets plus the main 2" as usual. The 1" hoses can be routed up and fixed to the panel cover with individual outlets. They also make (as do others) a three-way "Y" shaped 2" duct adapter to split the secondary heater inlet into two hoses for a similar fixed application below the screen.

With the C-150 mufflers there's an option to add additional outlets to the heat muffs with 2" flanged and riveted duct adapters, or add Y adapters to split the single outlet to feed two cockpit heat sources. Lots of choices as required. The advantage of the C-150 system for heat is the relatively large surface area of both mufflers...the larger the heated area the more heat can be extracted. Having lots of inlet air volume is important as well. I'm comfortable to -20F in my Taylorcraft but that's my limit for small Continentals in winter.

The biggest overall help in cold is to put a removable fabric/flexible material baffle right behind the seat to isolate the baggage area...like a curtain top to bottom and side to side. Fasten at the top to any tubing and leave the sides and bottom loose to access the baggage.
