I do not have experience with the electric start models, but I have owned AMT 180s and 280s since 1998. The engines have been very reliable for me.

I start the 180s with a leaf blower, but the 280 is in a Euro-fighter and requires a scuba bottle. I use the AMT auto start unit and electronic data terminal. It only requires that the umbilical be plugged into the plane and the transmitter run switch be activated, there is also an auto cool down when the umbilical is connected.

AMT does not have a 160N engine at this time, they go from a 135N to 200N.

The AMT engines specs are on the following link:
