    Difference Between a Tuned pipe, and a Hot Pipe

    The "hot pipe" was a nickname for the Quickdraw tuned pipe they sold with their engines. It has since become one of the best pipes for gas motors. Compared to other early gas pipes, the QD pipe was produced in steel compared to aluminum.

    Safety shutoff.

    I don't like them! There are a pain to configure especially in a 2P boat. They add extra wire. They add resistance and another failure point. What you have pictured might work for a 75A setup, but try that on a 350A setup with twin batteries.

    OS 46 VR (M or F)

    Understood James, I do not have many spare parts for it. I am running mine in a 20 year old Road Runner clone which is well paired for the power of the OS. -Tyler

    James, what are you looking to spend on one of these motors? Mine is in great shape for a lightly used motor and I would consider selling it.

    3rd Party Printing and 3D library: Treatstock + GrabCAD

    For anyone that does not have their own printer but does have files, Treatstock is an excellent resource. You can upload STL files, choose quantity, material, infill, colors, etc and then have multiple vendors/individuals quote the parts. I have ordered over 2 dozen different parts off...

    Fuel proof resin?

    I have used the Formlabs Clear resin and their Draft resin with good results and durability to nitro.

    Motor size ???

    The last motor with the square head is an older JG motor. Probably a 23cc version. They were good motors 15 years ago, but they have been superseded by the latest crop of 26's, 29's and larger motors.
