Roland Surface-To-Air Missile The Roland was part of a mobile S.A.M. system. The missiles were fired from a tube. As soon as they left the tube, the fins popped into place. Different versions were developed by the U.S. Army and the French/German armed forces. The US and European missiles were fully compatible. The US version never made it past the development stage and was never used in battle. The model rocket comes with a lot of nose weight, required for stable flight. As a result, launches are slow and majestic. The weight limits altitude, which is great for smaller launch sites. The kit includes all parts required to build the rocket, including parachute kit for recovery. $27.95  Dimensions Overall length : 26.5" Diameter : 1.637" (BT60) Fin Span : 5.25" Weight : 5.7oz Recommended Motors Estes® D12-3, D12-5 Reloadable Aerotech® RMS D15-7 Challenges The fins are formed from three balsa wood sections, cut by the modeler using fin templates. There are two sets of fins, one which is glued on the nose cone. A smaller BT20 tube is cut, using the provided cutter guide/template. These cut sections go on the bottom of the rocket (the blacks area on the bottom). Painting the Roland can also be a bit of a challenge. There are many areas to mask off, no decals are included. These challenges make it a skill level 4 kit.
