support(included in a hardware bag M) to the tank, using a good epoxy resin.
Pag 14
Hopper tank can be positioned near to the main tank
Pag 15
Wood plate (O) included in the kit can be used to install electronic devices.In our model for we
simple covered a wood plate with Carbon Oracover
Pag 16
Fuel pump,filter and valve positioned near to the turbine using the wood plate N included in the kit.
Wood rib G can be used to insert under the inlet duct
Pag 17
How to stop the wings
The two carbon spar on the wings can be stopped trought the alu block already fitted in the
fuselage,Main screw trought gear door, rear screw you must create a holes in the fuselage.
Air Speed brake
In the bag you will find two horns and two steel pin for the airbrake,glue the horns in the airbrake in
the exact position like in the photo.
Pag 18
Make a holes for the teo pins in the bottom of turbine cover and insert the horns of airbrake on it.
You can move the airbrake with servo or air cylinder at your choise.
CG
The correct CG is located at 23 cm from the LE please see photo below,You can move it little bit
rear for increase aerobatic.Cg with UAT full and empty big fuel tank,gear down.
Pag 19
TROW
Aileron:15mm up 15 mm down,expo 60%
Elevator:35mm up 30mm down, expo 60%
Flap:take off 15mm
Rudder:20mm left/right
You can adjust these setting depending of you flight mode
In the starting sequence of your turbine we suggest to move the elevators like in the photo below,to
eliminate any problem with a low air flow and high temperature.
In flight when you push up the turbine,the model move upward so we suggest to make a mix with
elevators.
