Blade Modification - THUNDER TIGER Raptor 30 V2 Assembly & Maintenance Manual

Dear Raptor Customers:
The stock wood blades should be operated with a main rotorspeed of no more than 1700 RPM. If the blades
are going to be operated at more than 1700 RPM, such as for aerobatics, then it is recommended reinforcing
the blade root section with epoxy. The enclosed drawing illustrate 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 seem of the plastic grip and the wood
to seal it off. This adds more strength and prevent 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 3D aerobatics.

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.
6. Attach blade grips and tighten screws.
7. Wipe off the excess Epoxy.
