Thanks for all the reply's. Iset up the engine on a test stand today and tried several prop combinations. Iam trying to decide on either a 10.7 or a 11.6 both seem to run up pretty good and idle well. I guess Iwill just have to try both in the air and see which will be better. Iam leaning to the 11.6 as I think it will haul the plane around a little better. By the way the plane is a Space Walker by Seagull. I would like it to behave in a scale like manner. Iam told that the full size plane kinda puttered around but was capable of areobatics. Will keep you informed.
Thanks again.</p>
