Thanks Y-Fox... I am anxious to weigh mine, when all is said and done. Don't know if my figures will be anything anybody can use. I make a better tank builder, than plane builder. This is all just practice anyway... I already want that Apex... and a bigger plane, to put it in.... John O
I really like all of your ideas Brett, and you have the tech knowledge to pull them off. I work on a little simpler mind set, and have had an exhaust based heater, in my head for awhile. Many people are turned off by such, so I haven't mentioned it (another reason I have been so fussy with my exhaust) I only mentioned these products because they are specific and quality made. Thought others could benefit from them. The 2.5" blower looks perfect for what I have in mind, so am getting one to try. When I get something in my head...I have to build it first. It may be junk, and I throw it out...which I am not afraid to do...But, I will build it anyway. Just who I am... So, after I build it...I will report on it, and go from there. The greatest thing about this forum...Ideas and experience everywhere... !!!
I too was very intrigued by Fred's heater solution and the products that company, T7 Design, put out. I got hold of the USA distributors...no luck. So I wrote the director at the company, Adam Mudge...I believe, and he said he would be glad to mail me anything they have.. So I ordered the blower fan they put out... Will follow- up on that motor when received... John O
Good to hear from you, Randy. Hope you are getting lots of work time in (plane work that is). Been meaning to reach out as well...and Thanks again.. for getting that spline gear to me. Thanks to you...there is now a purdy little clutch unit.. sitting in that gearbox. One of my biggest problems now....is I want to replace everything...Just ordered a piece of stainless...Yup...new firewall. Tore out half my panel...going to put in new windshield...AND...pretty sure I am going to extend the pedals (mod)….I don't even have fuel to my non running engine..yet. Oh yeah...new fuel system too. See, it never ends. Glad I'm not building a whole plane... John O
Turns out...that wasn't how the piping turned out. After building the last pipe twice already...I realized that the profile was too wide, with the pipes stacked 3 wide as in pic 1...So I cut it off and...It is a little uglier, but the length is good, and the profile...much slimmer. Got the hole drilled and the bung for the O2 sensor...welded on, as well
This is how the piping turned out. I had to re-do the last pipe. When it was done, the first time...I measured it, and found it to be an inch short. Cut it, and added "more swoop" on the bend...and worked out perfect.
Buckchop… I had a heating system very similar to your pics. The major difference would be wrapping the metal around your exhaust. When I wrapped mine in a foil based heat wrap...what a difference..Then I made my intake into more of a scoop.The heat was actually quite good after that.. .Now I'm putting in a new motor, new layout....new solutions.
