RCRCM Hornet Motor Glider, Build Manual

RCRCM Hornet Build
March 2016
Introduction
The RCRCM Hornet is a fully moulded motor glider with the following characteristic:
◦ Wingspan: 2.027mm
◦ Length: 1.23m
◦ Kit weight: 850g
◦ Flying weight: 1650g (Carbon Option)
◦ Airfoil: RC Series
◦ Wing area: 34.6dm²
◦ Control surface: aileron, flap, rudder, elevator
It is similar to, but in many ways quite different to, the well known RCRCM Typhoon. The Hornet has
an enlarged cockpit area that makes for a lot of choice in selecting motor and battery combinations.
The major advantage of the Hornet is that it can be built in many flavours to perform a large variety of
roles from a hand or bungee launch pure glider right through to a entry level hot liner capable of high
speeds.

A ballasted nose cone and bungee hook can be fitted if a pure glider is required.

A motor glider with modest power can be built if gliding and thermalling is the primary function.

A powerful in-runner motor can be fitted if high speed powered flight is the objective.
In this build I have chosen to add a modest amount power in the 280-350 watts range to be used only
to gain height, hence forth being a glider for thermalling and moderate slope soaring. At around 1.6Kg
flying weight this glider will not float like a DLG but should thermal well in moderate lift. I'll not add a
ballast system for the slope to keep the total flying weight to a bare minimum.
I did also consider adding FPV (First Person View) equipment to thermal in a virtual reality environment.
If a total energy vario (as used in full size gliders) was available I would have gone this way. I'm sure
such a thing is not that far away so the Hornet may well end up an FPV ship in the future.
Unpacking
Inspection
When your kit arrives carefully inspect the box for damage before the courier leaves your property.
