Bob,

Pardon the dumb question, but is your Calypso a tail dragger or trike gear. If its a tail dragger, take a look www.lado-tech.com. They make electric retracts for the main gear for 60 size and larger planes. I have a set I am putting in my Ultrasport 60 kit and the quality of the retracts is outstanding especially for the price.

Happy New Year!!
