Nice Version2 improvement Jim! I'd make one like that - but If I had fancy trim like that then I would have one less excuse for bad landings... and now you have no excuses so I think I'm in a good position here
Bryan Dacus gets the tune spot on, and provides a top shelf EMS for Yamaha conversions. Just a matter of if ya got the budget for it There are cheaper ways but you would have some more DIY to deal with.
Hopefully the EAA can help us all with the evaporating insurance provider / rate spike problem that weighs on us all. At least better liability only options because I found that underwriters wouldn't quote me "just" that. The unique nature of your craft is super cool but must make insurance a real challenge! Fot my Kitfox I did find a seaplane policy at www.nwinsurance.net
In those skiplane tracks in the snow I find there is something deeply connecting to the nature of flight and to this special thing that only a few of us are blessed to experience. I cannot fully describe it, but it is something about the visual nature of the tracks as they first begin at touchdown - and then again as they almost magically disappear again upon liftoff... They are evidence of something rare and special that graced a stretch of snow. I too almost always hop out on the ground to look over my tracks, and also circle above and look down upon them before I leave the area. I find it, for some deep indescribable reason... entrancing.
At work yesterday or I would have met up with you guys. But did get a full day of flying around home on Fri. Also took my 9YO boy up. He wanted to "scout some camping spots" and he found one on a small island on an uninhabited remote lake (in pic below) that we apparently are flying back to "ASAP" to "camp for two nights"!
The rk400 clutch has held up extremely well in all the 120 - 140HP Yamaha applications for sure. Over a hundred of those being used over the past ten years and I haven't heard of anyone having problems, so that is a pretty good testimonial IMO. And in talking with Tony at TMR he cited many examples of use in airboats used for wild rice harvesting where it held up great despite much more abusive use than aircraft. I'd put it in a 670 without hesitation.
The Mohawk sprag clutch failed in the testing phase, so that is out. As far as the TMR400 mine is working great but I am afraid that Tony at TMR may have passed away and that option also may no longer be available.
I'll crank it up in the morning and go at -5, as long as in a few hours the sun will help me out a little and bring it up to 10 or 15 at least. Pretty wussy compared to the guys in the far north that have been going out in -30 or worse over the last hundred years or so! I read those books... I'm good with that level of participation
