Thanks Bobp, It sounds like we are talking about building one the same way.
I know it would not be a rocket but it sounds like it is feasable to build
one with the 912s and still put it on the 1500 floats. Thanks agian, Heath

-> Hi Heath !
->
-> Welcome to the list ! You don't have a problem - the 1450 lb
-> and 1650 lb Rebel kits are THE SAME KIT !! The 1450 lb gross is a
-> "suggested" gross for the Rotax 912 80 hp. engine, suggested so that
-> you will get very satisfactory performance. I have flown Rebels with
-> the 80 hp. Rotax at 1550 lb, and the performance was more than enough
-> to satisfy Transport Canada climb test requirements - I'm sure that
-> even 1650 would pass. With the 100 hp. 912-S, you will have a great
-> performer !
->
-> You are correct, though, that the CG range tends to be farther
-> back with this light engine - possibly the factory will be making a
-> new mount to move the engine a few inches forward, and allow fitting the
-> Rotax factory exhaust system, for more power. You can help by putting
-> your battery on the firewall, and your ELT and fire extinguisher on
-> the front side panels, bringing all the extra weight forward. You
-> could also install the firewall backwards, to move the engine forward
-> a bit, and give a smooth air outlet at the bottom, for better cooling.
-> And you could also add Wayne's firewall stiffener plates, for strength
-> and a few more pounds foreward.
->
-> The factory also sells a 1057 lb. gross Rebel kit - this is the
-> old Canadian Advanced Ultralight kit, and not a good idea for most
-> folks. It has lighter, thinner spars and struts, and loses a lot
-> of strength for the few pounds lower empty weight....
->
-> I flew our old Rebel on Murphy 1500 straight floats, with the 80 hp
-> Rotax - it outperformed our 85 hp. Aeronca Super Chief, but was nowhere
-> near a Rebel with 150 hp... but it was adequate, and burned only 3 gph,
-> of auto fuel !! :-)
->
-> My next Rebel will be a 912-S standard Amateur-Built Rebel (1650),
-> and I will likely put it on Murphy 1500 amphibs at some point.
-> I've flown a standard Rebel on Murphy 1500 amphibs across Canada,
-> with a 100 hp Lycoming O-235-C2C - with 2 bad cylinders (about
-> 70 hp ??) - not recommended, but I survived !! Given that
-> experience, I think the (over 120 lb) lighter 912-S should
-> give adequate performance - again, not as dazzling as an O-320
-> or O-360, BUT - adequate, and on only 4 or 5 gallons/hour of
-> car gas ! :-) (and a whole lot cheaper to maintain !)
->
-> Let me know when you are closer to ordering, and I'll help
-> you put it together .... (905) 457-5238 9 am - 10 pm 7 days
