Specifications

5.1.2. Corona motors usable in a Eolo
This requires choosing a 3.17mm shaft motor with a Kv of about 3300. This results in a power
motor for both the Corona and the Eolo. The Mega 16/15/3 is fairly mild for both Corona and
the Eolo.
5.1.2.1. Mega 16/15/3, Kv = 3000 rpm/V
• Corona: 10T
• Eolo : ?
5.1.2.2. Hacker C40-12S, Kv = 3500 rpm/V
• Corona: 10T
• Eolo : stock pinion
5.1.2.3. Hacker C40-9L, Kv = 3333 rpm/V
• Corona: 10T
• Eolo : stock pinion
The Hacker C40-12S is a little small for the Eolo and is probably not suitable for the Eolo in
warmer weather.
5.1.3. Corona motor usable in a Voyager E
This requires choosing a 3.17mm shaft motor with a Kv of about 3700. This results in a power
motor for both the Corona and the Voyager. You must be careful to limit the throttle on the
Corona because the maximum headspeed of 2000 will be exceeded if the throttle is not lim-
ited.
5.1.3.1. Hacker C40-8L, Kv = 3750
• Corona : 10T
• Voyager: stock pinion
5.2. Piccolo upgrade paths
The FP Piccolo requires a motor with a Kv of about 2500. There are two upgrade paths avail-
able: the Piccolo CP kit or the Piccolo Pro, which both require a motor with a Kv of about 3000.
The B20-31S and B20-18L have a Kv that's a little too high for an FP Piccolo so the flight time
will be short, but they will be powerful later in a CP Piccolo.
