Blade Modification - THUNDER TIGER Raptor 50 V2 kit Manual

Dear Raptor Customers:
The stock wood blades should be operated with a main rotorspeed of no more than 1700 RPM. For 3-D aerobatics
or rotor speeds more than 1700 RPM, the Thunder Tiger 600mm Carbon Fiber Rotor Blade is recommended (P/N
TTR 3827). The enclosed drawing illustrates how to remove the plastic blade grips and then carefully slice away
some of the covering material, and add the "thin" type CA glue to further strengthen the wood. After installing the plastic
blade grips, apply epoxy around the seam of the plastic grip and the wood to seal it off. This adds more strength and
prevents oil from seeping through. For beginners, the best rotorspeed is around 1550 RPM. For advanced fliers, a
good hovering RPM is around 1550, and a constant 1800RPM in idle-up for 3-D aerobatics. We recommend using
the Thunder Tiger TR-2000 optical tachometer to help you check the rotorspeed and to help you set the engine
mixture. This tachometer is especially helpful for beginners and we highly recommend it.

1. Mark around blade grips with a felt-tip marker.
2. Remove blade grips and cut covering lightly .125"
inside of mark, being careful not to cut into the blade.
3. Repeat for opposite side.
4. Trim bosses if necessary to allow tight fit to the blades.
5. Lightly sand inside of grips for better adhesion.
Apply Epoxy to blades in area shown top and bottom.
