If you live in a hot enviroment or plan on float operations the Rotax 912ULS will out perform the Jabiru 3300 with its liquid cooling and ability to swing a 72" dia prop at a slower speed (less cavitation). I think the Jabiru people are real close to de-bugging thier engine....just not quite there yet.
The Jabiru is around $4000 cheaper to install, simpler to install (no hoses & radiator), no prop extension...etc. The Jabiru 3300 is a very complete FWF pkg. Install is a 1 - 2 day affair. I was 5 days working my way through the Rotax install. The factory demo CH750 has a 10 bar oil cooler that should be in the FWF pkg instead of the 7 bar oil cooler supplied...difference in cost is $5 ! The FWF pkg from Zenair Midland leaves some things in need of improvement / upgrade. I have flown LXT for a around 2 hrs, Transport Canada has taken 5 weeks to "not" ..register my CH750 so far. The Rotax 912S engine climbed out at 800 fpm full gross with outside air at 36 degree C temperature. If I lived in Florida it would be the Rotax 912S for cooling issues and 2000 hr TBO. The Rotax 912 has 80% of the LSA aircraft market for a good reason.
I am using a zinc chromate primer. I apply it with a small "acid brush" (the kind with metal tubes for a handle and the brush is about 1/2" wide and 1 1/4" long). I get a bag of 36 for $5 at Harbor Freight. I did not want to spray it and intned to only prime the metal to metal contact areas.I bought a gallon from Rexcel Coatings out of Albuquerque, NM as my son goes to college there and I did not have to worry about shipping hazmat material. Hope this helps.

This may be a good simple way to post classifieds...
Unless they have made changes since my kit last year, only the skins are pre-drilled. But no worry, every 601/650 has been built just fine that way!
Thanks for your kind words, appreciate your support!
