Hello
I'm just starting into 1/4 scale and gas engine's. I have been told by respected people on RCU that these conversion engines will shake my glue joints apart and ruin my reciever and servo's. They do seem to have the money looking at thier aircraft to purchase what they want. I'm on a budget and have three Echo's some Homelite's and Weedeaters to convert but feel real lost at this point. I don't want to lose a plane and all the work due to vibration and would rather sell everything and buy a production R/C engine if this is the case.
I would arrpeciate you input and experience on this. Has there been any comparison vibration checks done on Factory R/C engine's and the conversion's?
I was told the difference was in the bearings and balancing of the crankshaft. I just made a prop hub for one of the Echo's and mounted it a heavy vice and fired it up with no prop to see how it turned and it looked great and the vibration didn't seem bad at all, although I'm sure the vice was absorbing some of this.
Thanks for your help. Best to all Ron
