Powerline and RC-Equipment advice Ultima 1 and Ultima 2:
Motor system:
The Ultima nose is designed to fit 28 mm motors with a spinner of 30 mm. Larger diameter motors may fit as well but might require modification by the builder (shortening the nose for example). The recommended weight range of the motors is 60-100 grams and batteries of 50-100 grams. The nose can be shortened by 10-15 mm to fit a 32 mm spinner thus allowing to move a heavy motor back to achieve a correct CG.Below is a chart of suggested motors for the Ultima series (Ultima 1 and 2). There are other options as well which will fit as long as they fall into the following requirements: diameter 28 mm and weight 60-110 grams
Light version: 250-400 watts
Normal version: 350-450 watts
Strong version: 450-600 watts

Servos:
A variety of servos can be fitted in the Ultima wing (Ultima 1 and 2). The recommended thickness of the wing servos is 10 mm. Metal geared servos are required for robustness during landings. 10 gram servos will do well on all flight surfaces in all versions but for the “Strong” version it is advisable to use bigger flap servos in case of harder landings with full ballast.Below is a partial list of servos which will fit the Ultima series.
