bolt on prop adaptor help

[Gav]

hello guys, can anyone help me find where I can buy the bolt on type prop adaptors for rc timer BL-2380/13 850kv motor with 4 bolt fixing positions as per photo.  hole spacing diameter is approx 11.5mm.  Wish I had a milling machine to make my own. thanks for any help.
If I can find this bolton type adaptor I will try it otherwise I am spending 85 quid on a set of dji motors but would rather spend a few quid lol.

did you have to chop off the original shaft or did you fit shorter shafts when you tried the bolt on adaptor?

[Gaza07]

I tried to turn the shafts around so the main bit stuck out the bottom but I couldnt shift em so I used a dremmel with a slitting blade and cut the buggers off   

[Gav]

will use workbench grinder for mine lol.  masking tape round the motor so I don't fill it up with filings lol ^-^

[Gaza07]

Should be ok just keep it cool coz if you let it get to hot it might affect the shaft have a tempering affect or something like that 

[Gav]

yeah I know as already ground them down a little already.  maybe hacks saw and then file it smooth to avoid the heat.

[Gaza07]

Yea that should work as long as they aren't already hardened and blunt the saw

Some pics of the prop adaptors and fitment method lol








you need to check it is central before tightening down the fixing screws.  There is a fine amount of adjustment you have to play with.

Look forward to your report on these Gav as I could do with some for mine

TEST flight has given excellent results.  Zero wobble / jello on fpv live feed from hard mounted camera to the frame.

I was running 10x4.5 props as 8" props did not provide enough lift with these motors. 

conclusion = bolt on prop adaptors help a lot with regards to vibration, and I would recommend if your motor accepts them (not many do though DOH!)

Thanks for that Gav I will add some to my next rctimer order, as ive got a few 2830s

quick vid showing the smoooth results
HobbyKing $14.00 FPV camera test
camera was a cheapo $14 hobbyking jobbie.  I reckon the focus is out a little to lol

[Gaza07]

Just watched the video yes very smooth did you have bad vibes before fitting the bolt ons  the camera does seem out of focus can you adjust it 

[Gav]

just tweaked the focus a little but could be better.  oh well not bad for $14 :P
