tiggerinva,

I think there is a new version for electric out, or coming out. I am not sure why, since I have seen the standard one converted to electric fly very well. Other than that, I don't think that kit has changed over the years.

If you build it, decide on your engine before you glue in the firewall. That kit was designed around some older engines that were shorter from the thrust washer to the backplate than modern engines.
