Great idea with the heat sheild how are you charging your pack now?galderdi wrote:Over the Christmas break I made a couple of minor improvements.
I added a heat shield between the motor and controller. Last time I competed the heat was rising from the motor into the controller and was making me nervous. If was a rather hot day, but this is Queensland so hot days are not rare. The heat shield is really excellent so I am confident this will mostly take care of the issue except if it is an exceptionally hot day (by QLD standards >35c). But I plan to also install a fan to extract any stray heat from the engine bay.
I modified my rear lower control arms (2 on each side). I added some thread so I can adjust them in and out to modify the rear alignment. This gives me some camber and Toe adjustment. It can't be adjusted on the car, at least one end of each arm must be disconnected so it can be twisted in or out.
The next event is a Motorkhana on Feb 12 followed by a couple more in March. But I am really aiming for a good result in the Khanacross April 9th.
Oatnet, you were right again. The controller was too weak to drive the motor. At least I am man enough to admit when I was wrong. My resistance to accept the facts was more about budget than anything else. It has been a painful experience from a financial point of view. But I am confident 2017 will provide some excellent results now that I am running the Zeva 1000amp unit.oatnet wrote:Yes! I'm glad Hill finally got the CA on your radar, because the (3) times in this thread that I have specifically recommended the CycleAnalyst to you for that purpose didn't seem to sink in.

Some of the better controllers have this built in, but stand alone data loggers are not expensive these days, and software for download analysis is freely available online.
Even just using a CA unit would give a lot of useful data, peak amps, max/min volts, rpm etc...
Wow that does seem like a good product and price. I have sent a message to their local distributor. I will certainly get a hold of one (Assuming they don't jack the price up by 1000%)
I am looking forward to someone else telling you that your Curtis controller is too weak to drive a 9" brushed motor, and that a $75 power supply will charge your pack in hours instead of days, so you can start enjoying what your build really has to offer.

Awesome. I should be able to take you for a run or two if you can make it on the day. Any photos you could catch would be very welcome, I seem to struggle to get action shots.sketchism wrote:looking great man, i am in town feb 12th if i have time i'll try drop in to willowbank and catch you!

Awesome mate what sort of charger did you get?galderdi wrote:I have finally managed to get a real charger for my car. So I am going from a 3 week turnaround to around a 3 hour turnaround. Yay!!!!
