Flywheel is only $350. 150 hours and no problems or kickbacks.

What I understand is that the new flywheel has the timing lobes changed so when STARTER ENGAGES ignition takes place a few degrees AFTER TDC, not before, as with the old flywheel. I have both a new set of Rotax soft start CDI modules and the original CDI units. Never tried either with the old flywheel as I was advised by Rotax that mounting a new flywheel would be far be the most effective and cost effective solution. So, with the old CDI I noticed it starts a slight bit rougher but not much. With the new soft start CDI its quite smooth. I think the biggest difference, though, was to go for the lithium battery. Not only saving 12 lbs up front on the foot well but much more consistent and higher voltage during cranking stage. The smaller starter cranks like crazy. Worked for me, even in the Canadian winter last year. I think the flywheel makes sense and exchange is about 1 hour when the engine is out.

You will need four of these for the VHF antenna construction. I'm fortunate because I work for a major Avionics company here in Sydney Australia and I had the Chief Engineer look at the specs for these toroids and he advised that you cant just use any old toroid - as suggested by someone in this thread. They all are manufactured for different frequencies and applications. One other piece of advice he offered is that if you are using copper tape to make the antenna, use the widest tape that you can find as this provides better performance over the entire VHF spectrum 118 - 136Mhz. In other words if you used thin tape, you will only have best performance at the mid-frequency but not so great at either end of the spectrum. The first number in the Philips toroid P/N "4" refers to the "mix" in the ferrite. It is suitable for VHF at 100MHz. He found a suitable replacement that had an inside diameter is 5.4mm that will slip over RG400 (4.9mm) safely. You can buy then in a pack of 10 from RS Components. In Sydney I can buy them for about $15 (including delivery). check http://au.rs-online.com/web/p/ferrite-rings/1741229/ I hope this helps.

I have been advised that the balun will pass all the transmit energy to and from the entire length of the co-axial cable. This is what you DONT want from a transmit antenna and can damage your radio. Baluns are used for receive antennas e.g. VOR antennas.
