    Now available on the site.

    These are American made, machined from 6061 T-6 aluminum with grade 8 equivalent bolts and instructions to make the change to a single bolt setup.

    Seen here, the 50cc adapter. 4.0 ounces weight, subtract the old long bolts and the prop shaft for 1.8 ounces you have a net gain of about 2.2 ounces on the setup.

    The adapter measures 7/8 of an inch in thickness, so when you have mounted it your engine will go back 7/8 of an inch to keep the same prop line to the cowl. Thhis will require shorter standoffs and it will make up for a portion of the extra weight of the setup.

    The 50cc adapter was released over the summer. There are a few out there with regular daily use....no issues.

    50cc bolt is 10mm and tapped for a 10/32 spinner bolt.

    No more looking for the drill jig....

    One possible large benefit is that when the engine moves back 7/8 of an inch and so will the muffler....in some tightly cowled setups this can help with how much of the cowl that is required to hack up to accommodate a muffler (usually side dump) setup.

    Tutorial to follow.

    The 30cc single hub starts at 70 gm, deduct 26 gm for old hardware and net gain on the engine is 44 gm or 1.55 oz

    The hub thickness on the 30cc setup is 3/4 of an inch. Also the 30cc center bolt is 9mm to accommodate some of the smaller prop/size manufacturer. The adapter kit comes with the phenolic shim that allows the prop shaft to fit inside a 10mm prop hole. You can see the shim in the photo.

    Looks nice! Do you think if you were to go bigger than a 50cc it would cause problems? I would def like it for the 30 cc size if I ever had one

    I have the 100 cc prototype going out this week. It will be run on a DA-100.

    The designer was not sure if there would be any prop slip issues so he designed a pin (can be seen in picture) that can be used for this problem. We will run it without first, I am confident it wont slip.

    Ralph Cunningham has been running the single bolt setup on the GT-80 race engines (16 hp) for a number of years with no need for pinning, no slipping.

    Second picture is the weight that comes out of the setup in long bolts and prop shaft....

    Again, this unit is right at one inch in length....so you engine goes back one inch with shorter stand offs....

    Looks nice! I believe it will be very nice for the 50cc planes out there that you need to change the cg.

    Looking forward to the 100cc single prop bolt. This should make changing props a snap.

    Thanks Clarke...as I have done with the 30 and 50cc.....we will fly the 100cc adapter and insure it lives up to the standards before the release.

    The 30 and 50's are in stock...

    Rich you shouldn't have a problem with the 100cc. The Extra you saw me fly in Tampa had my BME 105 on it and its just a single bolt from the factory. Made It easy to put the JC on there too :)

    Very nice. Does it double as a speed-loader for 22 cal? When I saw the forst picture, that's what I thought it was before reading your intro....

    Hi and thanks for your question. The pattern for 6 bolt versus 4 bolt will be such that the bolt holes wont line up. So it wont work.

    Is that the same bolt pattern as is the DA-100?

    Clarke (Rush 7) has the protype for that size. I was waiting on feedback on it with some flight time before producing any for resale.
