Blue Ninja E2X Model Rocket Kit

This is a simple-to-assemble kit and is a great introduction to 24mm motors. It features a nice fin system that assures straight fins and also has a simple plastic motor retainer to fit in your motors. You can easily build this kit in an hour or so and be out on the field to launch in no time. It is a really good kit for smaller kids to help with since the large parts and assembly method allows them to help and not lose interest while building. The size of the rocket makes for a great demonstration bird for a moderate-to-large sized field. The C-11 sized motors give it a nice slow boost and keep the altitude low enough to recover in a soccer or baseball field. The D-12 motor gets the rocket to 700-800 feet and is easy to track the whole way - you just need to make sure that you have the recovery room as it tends to drift a bit further than expected. A great rocket with only one catch - you cannot use any of the reloadable motors in this due to the plastic motor retainer. However, this rocket is more suited to the C-11 and D-12 rocket motors anyhow and the recommended motors yield great flights.

The Blue Ninja is a great demonstration rocket because it's easy to assemble, rugged, takes off nice and slow and is large enough to see at altitude. I have launched mine many times in small to medium sized fields and it descends swift enough on the chute to not drift too far away or onto houses or trees. The C11-3 is highly recommended for small field flying with this bird and D12-3 or D12-5 for medium sized fields.

Our first flight we used 302317 - Engine Adapters Standard to D, este C6-5 rocket engines. According to the este motor spec. The maximum lift off is 4oz. It did struggle and reaches an altitude of 125 ft. A success flight, but when we used a Quest C6-5 it crashed landed and never reached the same altitude as the este C6-5 motors. The Quest C6-5 engines did not have the same thrust or power than the Este C6-5 engines. Use these adapters only with Este C6-5 motors not Quest if you are launching in a small field and the rocket weight is not more than 6oz.
