#8 Florida Car
Permalink  
 

Hi, My name is Andrew, I go by Drewjet or Drew. My friend Steve, known as Slam, and I have just started racing this year. We are #8 FL. A little background on us. We met flying RC Combat and became good friends. As electric RC airplanes progressed we decided to try flying combat planes, electric vs. Gas (Nitro). We did quite well for ourselves winning a few contests. I progressed on with my electric obsession, building an electric motorcycle and also a few bicycles. I now have aver 5500 miles on the motorcycle and use it as my regular commuter to work. Some info here http://www.evalbum.com/1511
We went to the Battery Beach Burnout in 2009 in South Florida and there we saw our first Electrathon. It looked too cool to not give it a try. We searched the net for info and ended up on our current design. Slam did most of the fabrication work and I built the wheels and did the electrical part of it. So far our hard work has paid off well. We have been to 2 races and won both heats and overall for both events.

Very cool Drew!

What battery monitoring system are you using? I see a black box on your steering set-up and we're currently looking for something to use on our next car.

Andrew,

The car looks good!

Questions: Is there an internal battery cut off switch? I can not spot one. If not, there should be one for the driver to use. It must be inside the car. The driver can not reach out of the car to turn it off.

It looks like there is no restraint over the drivers legs. Around the NW our interpertation of structurally safe includes a bar/ support/ strap over the legs to keep your legs in the car durring a rollover. If you roll the car and your legs pop out, you will likely break your knees or lower legs. The final picture you posted has this issue addresses.

Aaron

The black box is called a cycle analyst. info here http://ebikes.ca/drainbrain.shtml it costs $160.00

It is placed inline of you main power wires and gives you volts amps watts amp hours used speed distance max amps min volts watt hour per mile timer. Pretty much everything you wanted to know in one box. I can't imagine not having one.

There is an internal battery cut-off. It is a circuit breaker over the right shoulder on the inside of the car.

You are correct the picture of it in white had feet covering. After our first race we had to add some bracing to beef up the frame. It was totally stripped of plastics and it accidentally did not get added back on afterwards. I should have something on there prior to the next race.

Thanks for the comments!

Hi Andrew, I have the same throttle that you have in your car.  The trigger type.  Where did you get yours from?  Did you get yours from Cloud electric?  I looked just recently on there site, but they don't have them.  Said they haven't had a response from the supplier.  Did you get yours somewhere else?

Thanks for the help Andrew!  Cloud wasn't being very helpful with where to get some like this.

I have a question to ask Drew. What brand and model are you using for lithium ion batteries along with the brand and make of charger? I know you have to use a different charging system compared to lead acid batteries.  How much are they? Were you able to get a deal on the lithium ions? Or do you have deep pockets? My dad was wondering about the last one. I might be interest to experiment with something new and learn new things. Thanks for the help.

Zaine

I have 8 of these batteries http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=9176 they are wired up in 12S4P.
They are $55 a piece plus shipping. I think I got them on sale for $50 each. The Charger I use is no longer in production, however they have newer models It is made by FMA www.fmadirect.com
I use 4 of them to charge 2 sets of batteries with each charger. I can recharge in about 1.5 hours.

I highly recommend staying away from Lipo if you don't have experience with them. It can be quite expensive and also dangerous as if you make a mistake charging or connecting they are prone to burn quite violently.

The electrical performance is about the same as the yellow tops, the difference being about 58 pounds lighter.

A few more pics as we have updated a few things. My buddy Slam made the steering and back half of the covering hinge to make access much easier. Also we added wheel fairings and a tail section
