I have a few more questions. I have decided to go with a SkyBolt Bipe, arf, for this summer and then start a build of a Sig Hog Bipe, kit, this fall for the winter.

So I have also decided I want to add a smoke system also to the SkyBolt. I have read MinnFlyers "Got Smoke" and another thread that was started by Mods-R-Me when he built a kit SkyBolt. (I thought that thread was great) however I am woundering if the infromation from Got Smoke is still up-to-date, or is their a better system or way of doing it now.

The other question is that I want to use a four stroke and I would like to use a O.S.91 with a pump. Will the 91 be good or should I get a bigger engine. Or should I go with a 100 Saito. Any way I go as far as engines it will either be a O.S. or a Saito. I have not bought anything for this build yet, but I am planing on buying the items as soon as I think I know how I want to go.

Any other info. you guys may have I would love to hear it. Thanks.
