I have had a couple of threads on this engine conversion arena. I have had some good info passed on to me as to how to procede with a conversion. I ordered a Stinger 120 thru a friends hobby shop. I checked on the prices of Zenoah aircraft engines that maybe used and am not too enthused by the price tags on them. I did some research on conversions that may fly my Stinger both the 25cc Homelite and the 31cc Ryobi. I would like to know, what weedy engine most of you would use for this application? I found a site before, that had some really good pictures to go along with the instructions on converting different weed whackers and chain saw engine for model aircraft use. I lost the websites due to old computer syndrone, any help would be appreciated in locating that site again.
