Thanks, Gary[8D]

It is powered by a SimJet 3000 rated at ~14 kg thrust. It is very fast indeed. I am a little concerned about over-speeding the airframe, so I only use full power for verticals.

The Viper handles very good. Landings are relatively slow and steady. However, IMO nothing beats the Kangaroo/ Rookie as a first jet/ jet-trainer. They can take a lot of abuse (read bad landings). Simple delta setup, never drops a wing, really solid gear mounts, all landing gears in the fuse etc., plus cheap parts if you smash a wing etc, + that you don't have to wait a year to get the parts.

I am using Skymaster retracts and struts. Bought them along with the plane when Skymaster was selling them.
