Hi TopGun1122 I am getting a 4* 120 and I am thinking of putting a Gaser on it.I just put a 25cc Gaser on my 120 Ultra Stick with a 16/8 prop and it is awsome.I was thinking of putting a 25cc Gaser on the 4* 120 with smoke amd my son saw your tread so I came looking too see if you have started on it yet.If you have I would like too see some pictures if you have any.It will be a month before I start on mine but I will take pictures while I am buiting it and post them as I go.I am going too put retracks in mine too.I have a set on ( air retracks ) that my son gave too me after wwe took them out of his T-6 he had too bring his T-6 in a little hot on it's maden and in the grass and it pull his leading edge out of the wing so he pulled them out and put the standard gear back in it,Please let me know if you get the smoke in before I do and I will do the same too you.Thanks

Joe.
