The inability to change the blade angle at will would always leave me wondering if I bought the correct sized prop.
    Unfortunately Pete we have to also compare cost effectiveness

    So Glen I read that as the whirlwind does not have a crush plate? (I think maybe that is a stupid question)

In the meantime, here is a link to the PDF (first draft--feedback, input, questions all appreciated). My email is at the end of the PDF, or PM me here.

    Bill,

    The Specs say that they are only good for 150 Deg. And not to mount inside the cabin. Surely they will overheat on the firewall????

    Mine is mounted inside the cabin on the firewall. Been fine for a year and a half!

    This raises the question as to why they are not to be mounted inside the cabin? Is this just a lawyer thing or is there a valid reason? I certainly wouldn't want one causing a fire between my knees.

    Hmmm.....Its been on the lower left firewall for three years and I've not had a lick of trouble. I have not put a temp gauge there but I doubt it gets that hot at that location. Lots of airflow through there. When I open the cowl door I don't burn my hands and it does not feel all that hot. I have the Sutton exhaust so there is no exhaust pipe or muffler back there, it is all up front. If you had an Atlee system I guess that could make a difference. Battery cables tend to be big and heavy so putting the battery on the firewall makes the cable run short and it also helps in the winter, when preheating the engine the battery gets warmed up as well and that helps.

    Hope this helps

    Bill
    Very Blessed.

    Thanks again all for your help. I have lost considerable weight already (from my hip pocket)

    Have ordered:

    Whirlwind prop GA200
    Eathx battery
    Lightweight sump (ECI)
    Lightweight flywheel without pulley (Sky Dynamics)
    Plane Power gear driven alternator to replace front mounted
    Carbon fibre materials and tools (plan to make new floor boards, seat bases and backs, nose bowl)

    Darren from Aerosport is an amazing font of knowledge and unbelievably helpful. Bruce from backcountry also very helpful re: props and ideas.

    Goal is to loose 100 to 120 pounds. Already lost 28 by removing cargo pod and Alaskan gear steps. Lights, tanks and pumps to come out next.

    If you’re worried about it, why not buy the one that is intended for use in the cabin?

    That does not answer the "WHY?". The ETX900 is non vented. If the battery doesn't need venting it can be used inside the cabin. I'm more concerned of whether or not a fire hazard is the reason. There is a good article on these batteries in the December issue of Kitplanes. http://www.kitplanes.com/issues/34_1...s_21972-1.html If there were a fire hazard reason I wouldn't want it anywhere in the airplane. The article indicates that the EarthX batteries are safe.
