Brushed or Brushless.
Bill, As a matter of purely personal preference, I've always used good old fashioned brushed motors. I like the 'grunt', one ESC (as long as stall amps are covered) and easy to swap out if one fails- cos generally they are cheaper! Hope you …

Hi RH, Thank you, that's good to know, I'll be using 17mm thick plywood for the sides just because that's what I have here, so it will be a heavy boat, looks like the 540's have won the day, phew lucky choice , My plan is to build the hull …

Identify Brushless Motor
No nothing I have plugged a 6s Lipo on to it and it all works fine, I will fit in to the sea queen and give it a go. But I plan to refurb the boat as it’s looking a bit tatty.

Identify Brushless Motor
Can anyone help identify this motor, I’m rebuilding my Aerokits Sea Queen and would like to use this to power it. I know the ESC is 200amp.

Brushless motor couling
Steve, An alternative to sawing off the threaded part of the shaft at the coupling end. Buy the spiral coupling with a 3mm I/D at the output end. Drill it out with a 4mm tap drill, = 3.4mm and tap a 4mm thread 0.75 (normal) or 0.76 pitch to …

Thanks Rowen Forgot that older shafts were like that. Since I got my mini lathe and milling machine I've got used to making my own! Cheers, Doug

Not unusual. Some shafts fit both screwed propeller and a screwed coupling, thus threaded at both ends. If you want to use a coupling with flats and grub screws, just cut the thread off. May have to shorten the outer tube to compensate.

Thanks again. Strangely enough the prop shaft is threaded on both ends. The same thread on each end. Cheers.

Hi Steve, The inserts of the spiral coupling are not threaded. They are secured with grub screws. That's why I milled depressions in the shaft to prevent any slippage. See my 2nd pic below with the shaft and coupling on the mini milling mac …

"The centre of the sleeve can as also be filled with grease or oil to maintain lubrication " That's a neat idea Rowen Could give my old couplings a new lease of life. Cheers, Doug

Many thanks gents (I'm assuming gents, sorry if not), all very useful information for the novice! Next question if I may - my prop shaft was bought about 20 years ago and when I use my digital calipers the plain bit of the shaft is 3.94mm d …

Agree with the clackety clack noise. I slide a length of plastic tube over the coupling once all is lined up. This sleeve reduces backlash in the coupling and quietens it down. The centre of the sleeve can as also be filled with grease or o …

Hi again Joe, It was Krick! You can order them with a variety of input / output diameters. Cheers, Doug https://www.krickshop.de/e-vendo.php?shop=krick_e&SessionId=&a=search&SearchStr=searchfield_technic_0%3Astegkupplungen

Hi Joe, I like the spiral coupling a lot. Takes the full power of my 1000kV motor running on a 3S LiPo without a whimper. You have to be careful with the initial alignment though as it won't flex as far as UJs. personally I didn't consider …

Doug, Regarding the flexible spiral coupling, do you like them, how well do they work? To date, most of my couplings have been the universal joint type for 3/16" shaft and I am having trouble finding the non-metric sizes now. I have a lot o …

Hi Steve, First; you can chuck the 'alloy thingy' in your bits box You don't need it, unless you want to build an Everglades Airboat That's for attaching the prop (airscrew) in a model aircraft. Second; being an outrunner the only fixed par …

Forum
Brushless motor couling
From my point of view, you can screw the motor as usual, using an aluminium L shaped support, if the motor is an outrunner one, simply turn the "L" 180 degrees looking at it from the top side, and screw the back side of the motor, the screw …

This project came about as I often wondered what the output from a programming card was - could not be any different to the output of a radio receiver which can be used to achieve the same results. The other aspect is that they always seem …

Following the improvement gained on my RTTL installation, decided to do the same to my Brave Borderer - again on the bench. Removing the "Brake" feature on Fwds/ Rev definitely smooths the transition and gives better control. Looking forwar …

PS Peter, "I reckon that 1000kV and a 40mm prop are probably at the very top end of the useable combination range." Apropo combination_ If your motors get too hot to touch and draw a lot of amps (which I don't really expect) then you have t …
