I sent Mr. Bent and email as follows: Mr. Bent, In early January, I received the FAA notice that the registration on my airplane (N64086) would expire on June 30, 2012. So that I would not forget to do the RENEWAL before that deadline, I went on-line and went through the process of RENEWING my registration for an additional three years; at least that is what I thought I was doing. About two weeks later (quick service, thank you) I received my new registration certificate but was aghast to see that the new one is show to expire Jan 31, 2015 instead of June 30, 2015. Why did I not get a full three year extension on my RENEWAL. This was NOT a new registration which starts the three year clock, but a RENEWAL. I went through the on-line process early to avoid forgetting to do it later. For this it seems I was penalized 5 months. It is a non-event financially but the rule says that the registration must be RENEWED (extended) every three years, not re-registered, as if it was a new owner. I suspect this was a programing error if this happens only on-line. In any case, please rectify this short-change or re-write the rule and guidance so that we know what to expect. I would appreciate a response regarding what your plans are for correcting this.

That was a very sobering discovery for us. So after that we got pretty conservative with our attitude toward propellers. In the case of the GSC, I think it was a maintenance thing, but even that was something new to us because we never had that problem with wooden propellers. So our brains were creased with another wrinkle: beware of new gizmos around propellers. We had seen the spacer used on Ivos for quite some time before we started using it and had the sense that it had been proven in practice. When we needed a spacer for the Warp we didn't feel like being the R&D department for the Warp-on-Ivo spacer. We did not feel that we wanted to promote its usage because the Warp had was heavier with higher inertia and stiffer blades. With the centering boss, all the keeping-the-prop-centered loads are taken off the prop bolts and transferred to the very substantial center boss; it's a more conservative and the traditional approach. Hanging everything on the prop bolts didn't seem right to us for such a heavy and stiff propeller - we didn't want to be the test bed for that combination. Better to take the conservative approach and use a more conservative spool extension. In a similar vein, we did not feel comfortable using the Ivo originally because we felt it was too lightly built. If TOK had ever gotten into the prop building business, the propeller we would have made would have been built more like a Warp than an Ivo. We would never have invented the Ivo - it just would not have occurred to us to build something that lightly. I remember the thing that nudged us to start using the Ivo was Phil Lockwood. I was talking to him about props one time at SNF and I was raising an eyebrow at the Ivo's he was running on the 582s on the Aircam. He shrugged his shoulders and said, but they work. He further said that he had tested a lot of propellers on the Aircam by putting one prop on one engine and then another prop on the other engine and he could tell by the yaw of the Aircam which was pushing harder and he felt the Ivo was doing the best of any prop he had tested. So it was after that conversation that we started looking at Ivo's more seriously.

I have been using the one that I got from tok on an HKS with a warp for 140 hours now. Larry >>>>>>>>>>>>>> Larry i had a prop spacer built, then to keep the bolts from having to take all the shier, there were some flange holes in the 912 engine that were larger than the bolts, so i had some bushings made that fit into the holes of the prop flange,, and then the bushings were larger where they entered intgo the spacer, then i had the holes in the spacer drilled out so the bushings would go in, the bushings were drilled out to fit the prop bolts, this way the bushings hold all the shier load of the prop. and it has been so long i beleve there was bushings between the spacer and the prop as well. ________________________________ Message 16 ____________________________________ Time: 09:36:16 PM PST US Subject: Kolb-List: Re: RotaxEngines-List: 912 80 hp back-fire on shutdown From: Richard Girard There are two distinct and opposing conditions that could cause your engine to backfire. Too rich an idle mixture letting unburned fuel slip by the valves into an exhaust system already heated by high EGT's when the power is pulled back on approach. Or the mixture is too lean and it's on the verge of running on after the ignition is shut off.(my Harley used to do this on warm up when I pulled the choke off too early). What is your idle RPM before the stabilization run? Is it different after the stabilization run? If your heart can stand the strain, let it backfire one last time and immediately look at the plugs. Do the same after a stabilization run and note if there's any difference.
