Minimono Upgrade Drive Shaft DIY

[MiniMorris]

Well I got it working now. Thanks for all your help!

On motors and props,
I have a Mini Rio, which is more sensitive to flipping than Minimono. I have upgraded my driveline from stock to the 0.098 flex shaft, and I use a strut too.
I have noticed that what applies to the larger boats does not translate well on these small boats.
On the larger boats, people on this forum use lower KV motors, higher voltages, and much larger props. That works fine, but for a given hull size, there is a limit on prop diameter to maintain good stability. Too large a prop, 36mm, or so, and it flips pretty easy. I have found mine runs much more stable with a smaller 30 mm prop. I use much higher KV motors to get the RPM and speed up and control the load, and hence the temps, with the prop. I run a 4400kv motor with a Seaking 35A esc on 3s lipo, near redline for the motor. She is quite fast. (I don’t have any vids) I just started out with a small, low pitch prop, and worked my way up to an x430

You are running a 4400kv motor and Seaking 35amp in the Mini Mono or Mini Rio?

It is a heavily re-enforced and mod Rio. The dimensions are not much different than a minimono now.

I am running 3600kv and a seaking 60amp, 3S, and it is a lot of juice for the Minimono.
Some pics and/or video of your super Mini Rio would be great!

First off from a new member thank you for this great post it has helped a ton. I received my parts today and already had the guts removed from a recent upgrade of the esc (seeking35A) and a new aliminum 1.5" rudder. My question is what is used to secure the shaft in place? I removed what looked and felt like hotglue from the old shaft but was wondering if I should use epoxy for a more permanent solution?

Any advice would be appreciated.
