    Barry, When I removed the wrap there wasn't any corrosion under it. The stuff turns into a "relic" and won't hold water or moisture. You have to be careful with it or it will fall apart. Dick Maddux Milton,Fl

    Rick, Thanks for the prop balance info and Roger I will check out that balancer. I didn't balance my previous Warp but didn't think it was that bad at all until I installed the Kiev. My "old" Warp is a taper tip with nickel leading edges and had been on the plane for over 12 years. A recent gearbox overhaul, in an attempt to solve my "run-on "problems, revealed a gearbox in good condition with little to no wear. However, I was going to the Kiev anyway because of its reputed smoothness, quietness, lightness, performance and overall beauty. 4 out of 5 is not bad. I am very happy with it and no more runon(backwards) at shutdown! I will get the balancer for my own use and also other LSA aircraft. Dick Maddux 912UL Milton,Fl

    Hi Dick, I pull the entire prop and hub off. I put all the bolts back on and balance everything from the gearbox prop flange forward. I always find them out of balance. If you never try a static balance on a prop 95% of the people won't know it is really out of balance unless it shakes the whole plane. Most people think that tiny little vibration is normal and some you can't feel. Props are like our carb balance at 100 hrs. They are always out of balance until proven otherwise. -------- Roger Lee Tucson, Az.

    Dick: I know this is a difficult question to answer... Did you notice any temperature drop in the engine compartment after installing the wrap? And... What was your reason(s) for installing it?

    Hi Barry, The wrap Mfg claims a 70% reduction in radiated and convective heat. I don't know if it is really that much, but if you land your plane would you put your hand on your exhaust pipes? Not without loosing some skin. I can land and put my hand on my pipes and keep my skin. With all the planes I have done the header wrap on I have not seen any downsides or any issues. -------- Roger Lee Tucson, Az.

    Interesting topic! Sorry to interfere but do you have any pics from your installation? I think the exhaust are really hot and too close to everything under the cowling ransbuilder sauli ----- Original Message ----- From: "Roger Lee" <ssadiver1@yahoo.com> Sent: Wednesday, August 04, 2010 2:40 AM Subject: RotaxEngines-List: Re: Header wrap 3+ years later > > Hi Barry, > > The wrap Mfg claims a 70% reduction in radiated and convective heat.
