Two people have Superstars in our club. They fly a little faster than your average trainer and a lot faster than a Kadet LT40 or Kadet Senior. This is with regular plain bearing 40 engines. The OS 46 FX is an excellent engine and was a good purchase. Your Superstar will be very fast with this combo.

This is not a bad thing. The only reason I am mentioning this is to make sure you have a seasoned flyer (preferably your instructor) make the first flights. With that in mind, everything will go great. Have fun and welcome back to the hobby!
