You will have to install the remote glow plug adaptor
(TTR3803). With the opening for engine cooling located
at the bottom of the engine, you can either use the glow
starter from the opening or install a Built in Glow Plug
Extension Wire (TTR2174) and secure the connector on
the fuselage for easy glow ignition. Also suggested is the
use of Precision Fueler Valve (TTR1115) which is very
convenient for both re-fueling or de-fueling and could filer
the fuel when fueling.

Install all the windows on. It is recommended to secure
the front windshield first then the front side windows.
You may skip the installation of the rear side windows, as
it is easier for you in case of tuning engine or adjustment.
Shall you decide to install the rear side window then you
might need to cut a hole for your index finger's insertion
allowing easier securing of the windows. Remember if
rear windows are installed, a needle valve extension and a
small hole for tuning the mixture metering screw ( idle
screw) are required. Even the RX battery on/off switch
should be installed on fuselage.

Test Flight

1. When hovering you MD, try to keep rotor speed at
approximately 1350~1400 RPM. The higher RPM will cause
vibration at the small tip fins.
2. Check the helicopter and fuselage to see if there is any loose
screw after each flight.
3. It is easy to get nose up in speed flight, please trim the
elevator down when swith on the Idle. Suggest to off set at
about 15%~20%.
