Re: DO ANY OTHER ESC's WORK WITH ASTROFLIGHT MOTORS

I have successfully used a Hobbyking Sentilon HV100 ESC with an Astro 3210, but I would still recommend the Castle Creations ESC in preference. Most important point is to add extra capacitors as per examples on ES, whether using Castle or any other ESC. You can also provide some extra insurance by u...

Re: DIY Aptera knockoff?

Here's a three-wheeler being made by an Aussie light aircraft manufacturer. It looks a lot closer to the Aptera stylistically than some of the others posted on this thread. Sounds like they are serious about making it, have done moulds for the body etc, they are taking expressions of interest at thi...

Hey Chris, have you seen Sutho's car using the EVO motor?

I did wonder myself whether the motor could fit in a bike. Looks like it would chew into the available space for batteries though. :cry:

Re: A123 20AHr Pouch Cell Battery Build & Info Thread

Thanks for the advice Matt. Hey jamo, the cells were from Victpower. I used DHL after reading someone else's experience with their slow airfreight - and I'm glad I did. Arrived pretty quickly, around 3 days (add a few days for multiple emails to Xin). Cost with shipping included was $25 ea, managed ...

Re: A123 20AHr Pouch Cell Battery Build & Info Thread

Well, I've recently joined the club! I bought 70 cells, will eventually be used in an e-motorcycle but may find themselves in other projects before then. All cells measured 3.27 V (+/- 0.01 V), undamaged except for the following: Two cells which were on the top tray of one of the boxes were deformed...

Re: Chain Drive How To's?

With your original plan, there is a way to use a standard right-hand-threaded freewheel for a left-hand-side drive system. Simply have the freewheel on the front sprocket (attached to motor), then have a fixed sprocket on the left hand side of the rear wheel. If your wheel has the 6-bolt ISO mounts ...

Hey guys, the Leaderhobby 6374-180 looks physically identical to the Hobbyking Turnigy 6374-170 (older SK series) which does NOT have a skirt bearing. However, I have been running one of these on my wife's bike on a Kepler Mk1 Drive over the past year, around 500 km on 5S with no motor problems. Spe...

Re: 2012 eFXC/TTXGP Australia - Rd 1 Wakefield Park

That's a shame that the number of competitors has decreased from last year rather than increased. (Obviously no-one took up your offer to run the Voltron, Chris!) It would be great to see half a dozen bikes on the track together. As far as I know Catavolt is running pretty much the same configuratio...

I've used "Speedview" by Code Sector. Nothing to complain about, it works pretty well, display is configurable, can even do a "head up display" in your car. :)

Re: Oil cooling your hub- NOT snake oil!

Another idea for ventilation - the rubber plug could just have a small slit cut in the centre of it (e.g. with an exacto knife). Should only open slightly under pressure.

Re: Left and Right side disc brakes from bike for gokart?

So, if it's really going to be quite similar to a gokart, then why not use similar brakes - that is, a single disc mounted on a solid rear axle?

If you're really stuck on the twin disc idea, I don't think it would be a problem to flip the caliper around the other way.
