Motor
|
 |
I needed a proven, reliable and powerful electric motor in order to
fly the Impact with authority through the F3A schedules. They don't
come a lot more proven than the Hacker C-50 and matching Electronic
Speed Controller.

Servos
|
 |
DO NOT try and cut corners here!! The Impact is a precision flying model intended to compete at the highest level. You will only get the best out of the model if you put the best servos in it! Cheaper, less powerful servos could be used but you will be compromising the model's performance in doing so. Recommended servos are the JR8511 for ailerons and rudder and the JR3401 mini digital servo for the elevator halves. A throttle servo will also be required - don't cut corners here either!
|
JR8511 £65.00 each |
www.alshobbies.com
|
|
Metal Servo Arms / Discs
|
 |
The JR8511 servo is phenomenally powerful and needs a
strong and reliable horn to transfer that power to the control
surfaces. Composite-ARF do now not recommend the use of the white
plastic discs that come with this servo or indeed any plastic arm. Instead,
use a metal arm. You'll need 4 on the Impact.

Arms approx £6.00 each |

|
Glue
|
 |
To ensure the ultimate bond when
dealing with the composite materials used in these kits use Aeropoxy.
Although quite expensive it gives good working time, will not run or
sag and when dry gives a phenomenally strong bond.
