my dad has a Telemaster Sr. (8ft ws) on a very calm day the Telemaster is a great flying plane and will slow down to a crawl.... his had a 61 2 stroke then i upgraded it to a 91 four stroke... maybe because it's so big and light, i felt like it was harder to fly than a standard 40 sized trainer on a windy day.. turning on a windy day requires a lot of rudder aileron coordination to efficiently turn... similar to a cub
