Very simple Rocket t' build, great for t' novice. Another Retro kit from Semroc and a great flyer. You can add alot o' Fun t' this rocket when used with t' booster that Semroc offers. Blimey! T' booster will lift it about 20 feet and t' rocket will almost stop in t' air when t' primary takes over and blows t' booster off t' send the Rocket on it's way. Very cool with everythin' happenin' low and slow.
