    Well didnt get much time to work on the doors today, but i did get a couple pieces cut and bent to rivit to middle of the door to cover where the upper and lower pieces of lexan meet. I also (while at Lowe's) picked up another roll of weatherstrip for sealing the doors to the fuseloge. I find one D shaped piece seals the doors up real nice for winter.

    One helicopter I flew had a Janitrol, outside next to the engine. It was terrific, hot air by the boatload.

    Yeah I had to get over that too!
    I wont profess to being the smartest or most experienced guy but I might posssibly be the one who has researched, investigated, networked, and talked to the most people about this yamaha thing.
    And in all that research I have found the C / E gearboxes to be mega "overachievers".  They have an incredible track record on the Yamaha engines.

    Do  a search for janitrol heaters... they are in lots of certified aircraft and are flying every day without blowing up... they also only seem to work about 1/3rd of the time   My buddy has a lake with one in it that is not working and its almost 3k to replace it.  Right now he is flying with a 12v ceramic heater in his plane...

    on our planes the lifes blood is the coolant.  The more plumbing we install the more potential leaks we introduce.  Not to mention that plumbing gets heavy fast.  I took 2 heater cores out of the inside of my plane when I got it.  I think I would rather deal with a the diesel heater I have never had troubles or issues with versus more potential ways to shut down the engine.  small leaks over time are easy to not notice.
    Say what one wants about the fuel consumption on the heater and the BTU output.  Burner technology is a wonderful thing and one can be made to burn hotter or cooler.  Yes gallon for gallon is has XX BTU in it, however, the actual heat output can vary greatly.  Dump a gallon of diesel in a bucket and light it off, then run the same amount through and efficient combustion chamber.  Tell me if you get the exact same amount of heat off it.  I already know the answer and I already have first hand experience with the amount of heat I get off these.

    At least two of us here have put quite a few hrs on Jabiru engines and like them.  I have over 500 hrs, and John has something like 3 or 4 times that much.  Neither of us has a lengthened fuselage either.  As far as that little rotary engine goes, I think the neighbors would be less tolerant of my airstrip and flying from it if I was using this engine.  It sure makes some noise.  JImChuk

    Great feedback folks - as expected. 
    Zadwit, I've been focused on other projects but I like your breakdown on methodically proceeding with finding the smoking gun.
    I will be back on this thread w/my findings as soon as I do.
    W/respect to 2-smoke vs 4-stroke; a 4-stroke direct drive I think offers a bit more simplicity than the 582 configuration which as more points of failure and for a variety of reasons.  Sadly there isn't a 4-stroke that comes in at the weight of a 582 -- adaptable to these little birds without major lengthening of fuselage mods and what have you.
    THAT SAID!

    The added thickness in the tailfeathers due to added ribs may offer a very slight cruise drag reduction, but that's all.  That reduction is likely negligible compared to properly streamlining the tail struts and wing cabane struts, not to mention engine cooling drag as having the biggest payoff potential.  All at the cost of added weight & comlexity.  Personally, I'd blow it off as not worth the bother.

    When I bought my Avid Mark IV it came with a GSC three blade 64 inch prop. Great prop but as far as I’m concerned a little on the short side for the 582. This prop would really be perfect on a 503. The only thing about it on the 582 is that it unloads a bit to much in cruise. Other than that it pulls hard and is smooth. 
    I’ve asked the same question you have and talked to a few other local guys and the 68” seems to be a good length for the standard early Avid/Fox configuration. 
    I will be selling this GSC in the next month because I bought a Warp hub and blades. Once I get it installed I’ll get rid of the GSC. Right now the GSC is pulling the Mountain Avid through the air every chance it gets.

    Thanks, I don't know if this 55 HP will handle a 70" or not. I know it flys with a 68". But then a Kitfox has a big frontal area cowling. Actually too big, bigger than Hoot Gibson's boot.

    I would buy one and play with it if teal would make a gearbox for them. But Im not crazy about the rotax gearbox.

    I had plenty of clearance with a 70" on a Kitfox 1 with a 582.  JImChuk

    Model 2 Prop
    For you guys running a 2 stroke on your 1, 2, or 3, what is your prop length?  I understand a lot has to do with what engine but, I am considering the ground clearance in a level attitude. I was thinking along the thought of a 68". The original Subaru had a 70" and ground clearance was at a min.  I am running the standard gear and know many are using the higher bush gear which adds a bit more length to overall height.

    I like the idea of a heater mounted under the seat ur butt keep warm to boot.  But im still 50/50 on the deisel heater good idea but another thing to deal with, between the two probably not alot of weight difference? who knows whats best, but think id mount a water heater under the seat and duct it out into the cockpit be an easy way to get ur water lines hooked up right from radiator.

    Ok guys, 0.80 thick lexan, two pieces one top one bottom, new piece 5/8 aluminum tube with bend for center bar, lexan needs no heat to make it fit, edges close as can in center, then a strip of aluminum rivited down over center to cover the outside of lexan, easy way to make little wider i gained 1 3/4" on each side at ur elbow when sittin in cockpit.  $18 bucks for tubing, $120 for a 4x8 sheet of lexan.  Think ive cn this update in the originl model 1 build paperwork also.

    Hey Guys 
    I have been successfully operating a fibreglass spring on my Catalina. It saved me more than 2 Lbs of weight compared to the double steel setup and it does not sag as much/a bit stiffer which prevents my rudder to be hit (remember the Catalina is extremely tail heavy compared to the other Avids ....static, wings unfolded I have about 110Lbs weight but when I fold the wings the weight goes up to about 220Lbs!!!)
    I was going to make a spring but did not have the equipment to prevent air bubbles between the layup ( oven and bagging technique). I found the easy way to by a 84-96 Chevrolet corvette rear fibreglass rear mono leaf spring. like this one on ebay 
    https://www.ebay.com/itm/Corvette-rear-fiberglass-leaf-spring-84-85-86-87-88-89-90-91-92-93-94-95-96-NYU/372502247525?hash=item56badd3865:g:OcgAAOSw8PJb7Jlq:rk:8:pf:0
    With it I cut 4 different length to make the perfect one having good strength, rigidity and rebound. I tested mine to over 2000Lbs no problem
    See the picture of my tail assy below. Last picture is the before..

    Not sure on the weight, but it has to be less then a steel tail wheel spring.  On the other hand, being that Avids are usually nose heavy, maybe that's not such a good thing after all.  JImChuk

    1avidflyer, what did the fiberglass spring weigh? Seems like a good way to cut a pound or two.

    I would guess that plexiglass is easier to mold then lexan.  I think perhaps the idea of the window being bigger then the door and going back 5 or 6" has some merit.  That would in effect widen out the fuselage where your arm would go without changing tubing or fabric.  You might gain an inch or so on each side.  Let the door get a rack in it to fit the window so it protrudes out on the bottom somewhat perhaps??  JImChuk

    I used two tubes across the door on my challenger and used two pieces of lexan. Makes changing door glass easier and cheaper when you can do half of it when it gets scratched, and it will eventually.  It also makes it easier to fit the compound curve of the bowed out door with two pieces. A little care matching them up and the crack between them is very small. Or use a strip of rubber edging between the two.

    Ha I tried that ended up with a distorted mess. I just used two pieces of lexan one for the top and one for the bottom.
