E-flite Mini Ultra Stick ARF - Manual (Page 5)

5
The Mini Ultra Stick does not include a gearbox or propeller.
However, we do include two different firewalls for attaching
to the nose of the plane. You need to first determine what
power system you will be using, an inrunner with a gearbox,
or an outrunner. We even include a firewall stick mount,
which attaches to the Stick Mount Firewall. The Outrunner
Firewall can accommodate small and larger outrunners, with
options of mounting your outrunner on the outside with your
aluminum mount or inside of the nose directly to the firewall.
We are recommending the Park 450 Brushless Outrunner
Motor, 890Kv (EFLM1400) with a 10x7 propeller
(EFLP1070). This will provide you with excellent aerobatic
power for sport pilots and a worry-free Outrunner motor.
For a geared alternative, try the Park 400 Brushless Inrunner
Motor, 4200Kv (EFLM1100) with a 6.5:1 gearbox
(new HD EFLM240), 11x7 propeller (EFLP1170), and a
2100mAh 3-cell Li-Po battery. This setup will provide more
power for extreme flights.
It is very important to monitor gearbox wear and motor
temperature when using the 4200Kv motor. Lack of proper
throttle management using this motor and a 3-cell Li-Po
battery may result in damage to the motor, gearbox, ESC,
and battery. Adequate motor cooling is also very important,
so make sure the motor is cooled properly in the cowl.
