E-baja 12s - 06.05.2008, 02:13 PM

Here is a non Fine Design baja conversion, its total price is about 2000 bucks and will out power any electric car I have ever seen. It is running 12s2p 8000 true rc packs, hv 110 and a neu 2215 2y. It is not 100% complete yet but we went ahead and tested it out for a few battery packs and to get some test data and photos up. I say we, because it is 3 of us over here in Iraq that helped out to build it.

The battery pack in the photo is the 12s 8000, its huge, so big that we didnt have heat shrink big enough. function trumps beauty over here so we taped it up, serves its purpose. 2 6s 5000 true rc packs fit nicely and we ran that setup for about 30 minutes without any problems, batteries only took about 3500 mah to charge. not bad for such a big car. total weight rtr with 5000 packs is 23.5 pounds. no idea with the 8000 packs.

The hv 110 works like a dream using the pistix adaptor. we put two fans on it and it never gets too hot, i did not have a temp gun but i doubt it was ever over 150.

The 2215 is huge and has a small fan built into it so it stays cool, especially compared to how hot a neu can get in a revo. since the photos were taken, we made a cap similar to a rcmonster neu cap but we milled holes in it and put a screen on the inside so the motor can cool itself but keep dirt out.

The adaptor for connecting the motor to the pinion gear is really simple and would be easy for rcmonster to make them and the motor mount. these are the only two pieces that really require a machine shop. i would like to see mike sell these kits just so there is a cheaper alternative to fine design, he is bad business, i ordered a lehner motor from him in february and he has yet to get me my purchase, just keeps giving me the run around. anyways......

We did our testing on concrete over here but everything is covered in dust so traction is horrible. The ET graph with over 7000 watts was used with a dually kit, 4 tires gave it great traction, it even flipped backwards a few times. The second graph was with street tires and about 3 pounds of tungsten weights attached to the back of the car, like i said, traction is horrible with baby powder sprinkled on the road. The gps clocked it at 57 mph with both setups.

I think we can get it to go a little faster once we get the left side rear bulkhead to chassis support installed. without that support it tends to torque steer to the right, to the point of losing control when you get it going to 57 mph and floor it. 10hp is quite a sight to see in an electirc rc car. we blew two tires in testing.

The biggest shock to me was the power output of the true rc packs. i have been a devoted customer to him for some time now, i have owned all of the major brand of lipos and his are by far the best for your money, when it comes to value and performance. these 10c 8000 packs were putting out right at 180 amps and never went below 3 volts, compare that to some of the more expensive batteries.

Overall, this car is a beast, it drives like a real car and the tires even squeal on concrete. it is strange to see it zoom to full speed in a few seconds and only make that great electric humming sound. plus, how many people have pushed over 7000watts in their rc car?

There are limits to pictures posted using the forum image management tool. It might be better to use something like PhotoBucket to host them, and then post the URL to the pictures in your post. Also, you won't need to resize them.

the gas engine cant even compete with the electric version. current top speed is not that different, i think it does about 45 with gas, its the time it takes to get there that makes the difference. a buddy was telling me you can get a tuned gas engine for about 1000 bucks that will push 9hp. about the price of the electronics but without the awe factor. in all honesty, 10s would probably be more driveable and slow it down a little.

yes, the eagletree chart is 2 of the runs we made with the b5, the higher watt chart is with the dually kit, clearly getting more traction.

WOW... that's all I can say.
