Kyosho 11251P Calmato Alpha 40 Trainer Toughlon Purple EP/GP ARF  [KY-11251P]

Overview of the Calmato Alpha 40 Trainer

Whether you are taking first solos or tuning your stick-and-rudder skills, the Kyosho 11251P Calmato Alpha 40 Trainer provides a versatile platform. The ARF accepts both electric and glow setups and the Toughlon film improves durability for regular flying sessions.

Structure and flight behaviour

With a 1600mm wingspan, the Alpha 40 offers steady lift and easy trimming. The semi-symmetrical airfoil keeps behaviour predictable near stalls, and a 2.5 degree dihedral helps the model self-correct, making it easier to fly straight circuits.

Recommended power and battery options

For electric use aim for a 600-1000W brushless motor paired with a 14.8V Li-Po pack in the 4,000-5,000mAh range. For pilots preferring internal combustion, the airframe is sized for a 2-cycle 40-46 class engine to deliver the right thrust and balance.

Why this trainer works for clubs and solo practice

The kit includes a pre-assembled fuselage plus linkage parts, engine mounts and decals so build time is mainly installing electrics or the engine. Its combination of simple setup and sturdy coverings suits both club nights and informal flying.

With its dual power capability and protective Toughlon finish, the Calmato Alpha 40 is a practical trainer that balances ease of use with endurance for frequent flying sessions.
