Cap-Basic, an indoor beginner’s model with capacitor fed direct drive
Click here to download a PDF of the plan.
This model was designed for beginner workshops and shares significant construction elements with indoor duration models, such as paper tube mounting of the wing etc. The direct electric drive overcomes some problems with rubber such as high torque and sourcing. The electric components cost about 10 USD in total (Didel 7 mm/10 Ohm DC-motor, Samwha Greencap 5F 2.7Volt, Plantraco Tri Turbofan Prop 65 mm ). Flight behaviour and trimming are very trouble-free. The cap can be charged within 30 seconds with a simple voltage controller 3.3 Volt (e.g. LF33 AB) fed from a 9 Volt Battery (see picture). Flight times are up to 3 or 4 minutes.
