RE: Chrysalis or Spectra/Spirit
The Spirit/Spectra is a fairly good 2M sailplane in the non powered version. The EP version is very under powered if you use the stock motor setup that comes with it. I'd strongly suggest that you swap the stock brushed motor out for a brushless outrunner/inrunner motor so it can actually climb with a little authority. Also go to a folding prop system to give you a cleaner profile while gliding. Go to a Li/Po battery as well for longer motor runs that you can get with a Ni/Cad system as shown in the stock version. Other than the weak motor the Spectra isn't a bad EP sailplane if you build it straight and as light as possible. Construction is straight forward and pretty strong.
I don't have any experience with the Chrysalis as of yet, but friends that have it tell me its a good sailplane in either configuration. Eventually I plan on building one up and making a second fuselage with an EP system like I did for my Paragon 3m.
