Javron PA18 newbie

Hi everyone. We made the huge journey to Airventure the other month and managed to spend some time with Jay at the show, followed by a drive up to Brainerd afterwards for a visit. It was brilliant being able to speak to so many other cub people and the camera sure got a work out. If things go to plan, we should have an aereplane arriving within the next couple of months. I'm about to place another parts order from USA and had a question about the rear seat heater kits that Atlee and Univair stock. If I recall looking at some of the Legend Cubs, they mount the rear heater control box up on the firewall between the boot cowl and the inner kick panel, (keeping it separate from the stock pilots heater box) and the tube sits along near the door sill on the floor. Some of them made a nice shroud / duct for this to keep it out of the way and I'm thinking of the same. (pictures below). If I'm running a Vetterman style exhaust and the heat muffs are already being used for carb heat and the front heater, would you just install a Y piece for this rear heater? I cant tell from the picture, but it looks like the heater pickup in the kit is designed to be clamped to perhaps a factory exhaust or carb heat shroud? Im not sure.....Any advice on this?

The Vetterman exhaust system comes with 3 heat muffs. 2 for cabin heat and one for carb heat.

Mike
 
I installed 2 cabin heat boxes, 1 in the usual spot lower center firewall, and a 2nd on the r/h lower firewall which is routed to a NACA style vent on r/h kick panel. I have not flight tested this setup yet, but will keep you posted. Carb heat is taken from a half muff on the forward crossover pipe.

I made a couple of heat boxes front and rear. Easy to bend out of .025. I put a ball vent on both. The front mounts between the rudder pedals and the back under the seat. You adjust the heat with the balls. I loosley copied the Husky heat system. Works really good.
 
Yes but Jay has purchased some new machinery to make most of the airplane in house. Grove brakes were a real bottleneck for a long time and he is going to machine his own calipers and master cylinders. I talked to him a couple of weeks ago and he had around 30 kits ordered. I'm taking delivery of one that was ordered almost two years ago next week. If you are thinking of ordering one be aware that lead time on engines is about the same so order and engine at the same time.
