I have used these motors extensively when launching in smaller fields. These motors can lift a 3 oz rocket with authority, but they keep the apogee lower so you recover your rocket in small areas! I fly BT-50 size rockets which are great because you can actually fit wadding, streamers and 'chutes inside the airframe, unlike the BT-20 size and ESPECIALLY the BT-5 size tubes. Use a motor adapter to fit these mini motors into a BT-20 or BT-50 airframe tube. WARNING: Because of the high output of these motors, I have about a 1 in 10 fail rate, i.e. the motor over-pressurizes (CATOs) when rocket is several feet off the pad. (Remember the old B-14 motors? Same problem here). Build your rocket strong if you will be using these motors. For rockets 2 oz. in weight or less, I recommend the A3-4T which does not suffer from the CATO problems of the A10-3T.

These really get your smaller rockets off the pad FAST. We shot a sky duster up like a lighting bolt. it was very cool. The are strong enough for use in a 18mm airframe with an adapter, particularly if the model is small and or your field is

For the mini-engine crowd. These will lift your 1 ounce or less rockets out of sight. Streamer recovery suggested...
