G-Force Spindle Tool

Jun 13, 2011 No Comments

It’s not very often that I need to disassemble the spindle in the main rotor head, but when I do it’s always a chore to get out the second retaining bolt. But now, using the G-Force 4-in-1 Spindle Tool (part # GFA7077) the job is a snap. Just clamp the tool on the spindle and [...]

Flybarless Fury Conversion

May 28, 2011 No Comments

My airplane engines, stored in the same environment and using the same 20/20 heli fuel seem to all corrode and rust up within [...]

May 09, 2011 1 Comment

Glow plug wrenches have been around longer than I have, and they all do a great job. However, when installing a glow plug deep inside a helicopter my technique is to push the stem of the glow plug onto a small piece of fuel tubing.  I use this to feed the glow plug to the [...]
