A two guys in my club both had to have this plane when it first came out. They used the G23's and one had a B&B smoke system. They both sold them and when I questioned what were they dissatisfied with they both said it was underpowered. The first guy to have the plane said he would use a 150 Saito and the other said the G38 or similar. I have not had any major trouble mount my 38. And as far as the extra weight goes, this thing has a monsterous high lift wing. Have yaw read the thread were the fella mounted all the camera equipment inside his Taylorcraft. I believe he used a 2.4 BME or Brison for power and weighed in closer to 20#.
