Don't be fooled the PeaShooter is a piece of weak junk, I built it aand powered it with a Saito 120. Called GSP several times to ask about clarifying building instructions, got very little info from them. Its maided flight was great until it landed, it bounced on touchdown and the whole front end sheared off, very week construction. I wouldn't buy another GSP plane, even if they were handing them out for free.
