Hi:
If you do go ahead with a Pulse 125, be sure and read all the forums on this plane. I have one with a 25cc gas engine and the plane flies great. I have just come out of a trainer. The plane seems to have some flutter problems in the elevator. Either tape or pin the hinges on the elevator. I also took the covering off the bottom of the stabilizer and sheeted it with 1/16 balsa and then recovered it. A number of people have had the same problems.

Let me know if you have a questions.
