Hi folks-
I am certain this question is 'uninformed', but I can't seem to get good comparative information.

My next plane will be a gasser, and I would appreciate insights on brands.

Most of my club friends love DA, and some have had good luck with XYZ as well. What about the Fuji Imvac carried by Tower, or Evolutions?

Comparative benefits of EI vs magneto (I understand the starting ease advantage, and battery weight disadvantage of EI) ignition would be appreciated as well.

Finally, given the weight penalty of gas vs nitro, what is the practical 'small end' for gas? 20cc? 34cc?

Thanks in advance
