Flo sorry to read this! Did you think of any other controller brand like Fardriver or ASI etc? I see lots of builds using these with success. Hope you can resolve it quickly and enjoy your riding...

Hi Flo

Hi Flo
I like the braces but my one observation is you should have some spacer tube over that long bolt so that you can clamp it with some force to stiffen the brace up. The bolt will just flex or...

Merry Christmas Flo

Looks excellent so far though! I wish I had the motivation and tools you do to just get on with projects like this!

Great news Flo! Look forward to your ZXR build.

Well it's been a bit slow, I've been contacting motor suppliers and split my scooter engine casing to decide how to install and what motor to use in the build.

Honestly I'm struggling to decide...

Thank you Flo

I will definitely look on those sites. I have seen a few but they are unknown brands. Like you say though, if they are cheap then it is low risk to try them. And they should be...

Oh, sketch of fitting QS swingarm to the frame. Just quick idea.

Hello Flo

Thank you for your input. I have been concerned about the same issues with RC motors and looking for the largest motor I could use. I was hoping that this would be ok and the...

I found something interesting on ScooterLab today. Not sure how real this photo is but it's a Dragster with a QS Mid drive rear end fitted. Looks great. I might have to give up on the stock drive...

I've been thinking more about motors and sizes and mounting. I've had the idea that I can fit the drive shaft to the drive assembly, mount the stator of an outrunner over the shaft and to the casing...

So, quick update. Double actually, yesterday and today's brief forays into the garage...

Firstly, I finally got the generator flywheel off, no thanks to the Chinese Italian tool... It was...

Battery update, moved from battery post:

So here's some dimensions of the frame and you can see it is a compound trapezoidal shape everywhere so gets complicated to fit a battery shape. I'll...

So, the generator removal tool arrived...

What's worse than Italian build quality? Chinese made Italian build quality!

I found a Turnigy CA120 motor for sale. Anybody know much about these. I'm not sure using Tapatalk to search the forum is very good because I didn't find much useful info.

I'm thinking an...

Motors... I'm trying to find an IPM motor as large as possible without being too wide for max continuous power. With the narrow width I've got of 100mm. This means at the...

Looking like very good packaging.

Motor solutions update 2:

5: fabricate own swingarm using new QS mid drive motor design (see Revolt Motors - India design) with motor pivoting with wheel but much shorter wheelbase.
Would work...

Yes, thanks folks. The problem solving is enjoyable. My problem is when I can't find a solution or can't implement it that I get disheartened and distracted quickly. But I want this one to work out...

So I spent some time disassembling the engine yesterday I've had to order a bespoke puller tool to remove the generator flywheel, my puller won't budge it even with heat and worrying amounts of...

Motor solutions update:

1: modify current 2t motor by splitting the crankcase and fitting an inrunner motor in the bore. This would remove the engine mount though and be a small dia motor.
Could...

So I've been working on the drive system and found this video, basically doing exactly what I was hoping to do but without the enormous motor... Start about 8min in.

Really like your use of the mounts for the battery cage. How do you plan to cover the terminals etc?

Have you planned for mounting the motor yet?

Well I spent some time disassembling the scooter drive unit to see how I might integrate a motor into the unit. I quite like the appearance of the unit and was hoping to keep it in the scooter, kind...
