Yes - do not use a 4-way wrench on your prop - use a real wrench. I use a cresent. I use a 5/16 socket with a straight driver for the glow-plug. I haven't used a 4-way in years because I only used one side of it.

The prop balancer isn't accurate outdoors due to wind.

I like a power panel better than a separate glow driver - one less thing to charge since I have to charge the 12v anyway.
