My buddy searched high and low for about 6 months before he pulled the trigger on this engine he said it was the only one he could find that had exactly what he wanted to make his ultra lite fly again. He paid a lttle too much 3500$ on ebay. Unfortunately he passed way too early they say the good die young. Anyways imnot doing anything with it and he would want it to have a good home. I know the propeller that bolts onto it is at Sharkeys. Anyways im not asking as much as he paid for it. I have it marked a little under what they are going for i cant really recall what mods were done to this or what was differant about this one that made him want it. I do remember the samw one feom anothwr seller was only 3k and something the seller told him about this one made him spring for it even being 500$ more im sure someone who is familiar with these engines will be happy with this one. So this ad will be up until it sells. Text me i screen my calls. So if you shoot a text ill know yournot spam and i can call you back. Hope to find it a good home hopefully get it up in the sky thats what he would have wanted.
