Wow wierd that some on has all the plane in engine combos that I am aiming to use. I thought well each combo would have one person. You seem to have all the combos. I may look at trying to get the 46 ax for the GPcherokee. Imay look for another model for the 40 la any thoughts? Ialso have a tower hobbies 46 but man that thing seems to have some serious issues. I first thought it was me not setting it up correctly so I took it out to the field and had some freinds look at it. They tried tuning it and could not get it to richen. So I changed the fuel cell and all the lines thinking with advice that it has an air leak. It still had the same problem once again verified by others and not just me. I then replaced the carb and the remote needle. All new set up new o rings and the like. Ran it up again and same issue. So I shipped it and all the extra parts I now have for it. I am hoping that at my new field there will be a 2 stroke savant if you will maybe an engine whisperer. Someone to help get this troublesome contraption reigned in. I suspect that this engine if it is dependable will fly the cherokee but I dang sure don't trust it to drop it in a model and fly it. Maybe the fact Igrounded the engine for a year will teach it to not behave lol.
