Replacing hks700 for rotax

11 posts in this topic

Looking for advice on replacing old HKS 700e on avid heavy hauler model C. I assume best to go with 582 vs 912? New mount and cowling assume either way.

Just did some guessing on numbers and some quick math, and if center of engine mass is 25" ahead of the datum and if the 912 adds 35 lbs weight over the 582, about 6 lbs of weight on the tailwheel would offset the extra 35 lbs for the 912.  Say 40 lbs more at that rate for the 912.  Better engine though, but what will that do for your usable load?  JImChuk

PS,  I do have a newer style 582 Avid motor mount

The Rotax 670 is a nice alternative to the 582 - same mount, fits like a glove. Has 91 horsepower, needs more cooling than the 582.

I will probably part with it.   Also have the cheek radiators that are usually used on the MK IV.  Some guys use the Kitfox style radiator under the belly, though, especially if they have an older style cowl.   What do you have for a cowl now?   I'll send you a PM with my contract info.  JImChuk

unfortunately, it was recalled and never sent back for exchange. Not usable. It’s a throw away, sad to say.
