ORIGINAL: tlojak38
so, i built an engine stand to run an engine i bought a couple of years ago used, but never fired up. so, i get it running, and my throttle link pops off. the vibration opens the throttle to wide open. i reach for the throttle a little to fast and over shoot. got 5 nice deep cuts in my pinky, abd blood everywhere. the initiation is over now, and it hurts, but im ok. anyone else have a good story so i can learn what not to do before i learn the hard way again?? lol.
Sorry to say this is not a Test Stand for 2 or 4 stroke engines. I sell plans which allow you to build a "liquid filled" test stand for these type of engine applications. Total cost for materials you purchase at any home improvment store around $60.00 dollars US, time to bulid around 48hrs. Total servo control of engine throttle via your own trans, reciever, battery and one standard 38 to 44 gr servo! The test stand WILL NOT TIP OVER EVER! You will ruin any engine that is broken in on a hard mount. The bearings, con rods and or bushings are not designed to take undampened vibrations. Just think about it for a minute, your engine is mounted on your airframe on the ground, you start it, your airframe dissapates the vibration, once you become airborne the flow of air over and around your air frame further dissapates the vibrations from the action of the engine pistion moving up and down, can you imagine if the new car you buy had an engine on HARD MOUNTS!
Sorry you got injured!
