I do the new Bluehead 52, there are dozens of mine out there, it is a differant motor than the old 52 53
They are very powerful engines
I've just received my Magnum 52 XL from Randy, and what a jewel. I've purchased many motors from Randy over the years and they are worth every penny. They run as claimed and expected. I plan on installing the Magnum 52 XL in the New P-Force XL, it should be a killer combo.
