I have the Grate plans Space walker. I put a ST 75 in it.. I flys grate with this eng in it. I had to put about 2lb in the nose of the plane to Balinese it. I have a gasser the is a little more lbs then the ST 75 and all the led the I put in the nose. Is there any one that put a gasser in this plane and how did it work. Was there a probs with is
