Prop shaft diameter for the BJ 26 ?

[JLG627]

I'm trying to find out what the prop shaft diameter is for the BJ 26, 3/16 or 4mm?

Also, has anyone ever tried any of the motors from Medusa Research? I've got an entire seven page printout from their website and their "Afterburner V2" series of motors sound and look killer, but the only problem is I have heard virtually nothing about them in the world of RC boating. They are made right here in the USA and come with 60,000 RPM ABEC 5 bearings, so they must be nice motors. Any feedback or reviews would be very helpful!

1/8" on the prop shaft. You will need a sleeve to make 3/16" props fit.

Not sure on the motors yet.

Thanx for the info Steve, now I know which boat I want to go with.

Prop shaft sleeve?

So if a sleeve is needed, say to run an Octura x642, where and what should I be looking for?

Im in the same boat only I was thinking of the m642 prop or a 3 blade but I remember reading something that said to find brass tubing with 1/8th inside and 3/16th outside and make your own sleeve. Haven't looked for it yet. Keep me posted

Yeah, it does and hopefully apachedude is watching. Thank you, Brian

I sorted mine out a while ago... I used the sleeve from another Proboat prop that I tired.

My x642 works like a champ now.

I can't figure out how to post a new thread so I'm going to leach off of this one. I have a motor with a 3mm shaft and need a coupler to go to the stock bj26 flex shaft but I don't know the size of the flex , .187? Any help is appreciated.

I appreciate the reply but I don't have the same screen. I may be banned is my guess. I've emailed OSE about this and no answer. Thanks again for your help, Brian
