.50 Conversion
The Conversion kit contains
- Longer Tail Pipe (anodized blue)
- Longer Tail belt
- Solid engine mounts (anodized blue) in 2 parts
- Clutch shaft to suit 46-50 engine.
You also need to have
- 600 mm Main Rotor Blades.
- 46-50 size engine like TT50 or OS50 (<- recommended because of consistency)
- 46-50 size muffler, tuned pipe
Attention
- The conversion put a lot more stress on the rotor head, so check after each flight the plastic main grips but you may want to acquire a metal head from Quick-uk or Correct
It is recommended to have the following upgrades:
- Metal clutch as it may disperse better the heat produce by the slipping and is less prone to deformation than the plastic clutch.
- A better cooling fan like the one from Quick-uk or Correct because the .50 create a lot more heat.
- Radio flexing mods and good servo to have a tighter control system.
- Use a governor to avoid rotor over speeding during descent or when the pitch is near 0°
- Aside from a metal swash-plate and washout…
- Fuel consumption is 55% more than a .30
Conclusions
If you do not stress your helicopter with hard 3D, this mod is useless and the total cost of conversion (if you have no metal upgrades) can decide you to buy a real .50 class like the Raptor 50 or even a .60 class.
