Just purchased an unfinished ch300, fuselage and leading main spar with leading edge complete. There is space for wing tanks but no tanks. I emailed Zenair and was informed that there is no longer any support for this model. I have the full set of plans but no builder's manual. Can anyone out there send me a copy?

did you buy the one for sale in Michigan?


Yes I did. Are you familiar with it? I now have a builders manual coming from a fellow who has been flying his for several years now.



I see you are building a 640. My 300 has been modified to 4 place and is quite similar to a 640. I have hydraulic flaps which operate internally and counterweights on the rear horizontal tail. both of these alleviate the banana slot.


there is a great forum for the CH-300

About 20 owners and many builders post there


It’s separate from the factory forum and is a great resource for your plane… maybe you know about it already

great bunch of guys there … happy to talk about all things CH 200/300

Thanks Michael, I had no idea, will check it out.
