This is an almost brand new Amt 180 that just came back from US MicrJets yesterday. The motor is auto start and has just been upgraded to newest generation. There is a updated ECU since I paid to have the motor switched over to auto start. I sent it off because a fuel line got stopped up so They replaced it and the Stator and went through the entire engine and replace all worn parts. I believe the engine comes with A 6 month warrenty fro US MicroJets. ( I will check to make sure) The motor was test run there and I have not started it ( I only opened the box and took pictures). I am willing to trade for pinball machines in working order or cash. I just spent almost 1300.00 on these upgrades and I'm not going to give this away. This motor is almost $3600 brand new. This motor has 18 lbs. of thrust and is very strong. Visit http://usmicrojetllc.thomasnet.com/viewitems/all-categories/urbine-engines-for-radio-controlled-model-aircraft?&forward=1 . This is as close to new without purchasing it new. Please email with any questions or visit the web site above for all the specs. The serial number on the motor is 181072-L. Feel free to make me a reasonable offer.
