I have a 1 year old, mint condition, electric tow which is currently set up for a Lancair Legacy. It is a Shaller Engineering product. They are a solid (Texas) company with fantastic customer service. Go to this link to review the product and the company...
http://akm-tugs.com/aerokart/ It will work with any Lancair. I sold my Legacy and I have an identical tow for my Lancair IV, so I am selling this one. I paid $2,575.00 for it last year. I am will to consider and reasonable offer. My asking price is $1,750.00. I will pack it properly and ship to buyer at cost. Berni 228-304-1250
