Othello - I saw this build before but did not get around to commenting - It looks really nice and seems to handle very well.

I like it!

I have put together another video. This time i drove the car harder. A lot of sliding on the cold asphalt with harder throttle inputs and braking.

This obviously was harder on the components:
. Motor temperature rises by 26°C (78°F) within 3 minutes. Temperature rise can be as high as 10°C (50°F) per minute.
. On Average up to 60A are drawn out of the batteries per minute. Peak: 182A.
. Resulting in an average of 1,3kW und peak 3,6kW.
. Up to 1000mAh per minute are drawn out of the batteries.

At the end of the video one of the wings at the front of the body had almost detached itself. A result of the "crash" with the snow mound depicted in the previous video.

Thanx Brian. I'm really happy how it handles ... even during winter time when grip is at its lowest.

How did you fit the 1/5 wheels to your car? Thanks.

@big house
i bought some FG 18mm square wheel adapters which are 9,5mm wide (part nummer FG6107 i think). They fit perfectly onto the 1:8 truggy axles as they have a 8mm bore and can be tightened onto the axles with 2 6mm grub screws (i never lost one adapter while driving). You can find square wheel adapters with more width (i chose the narrowest i could find). You only have to make sure they feature a 18mm square and have an 8mm bore (i think 8mm axles are common to most 1:8 truggys or buggys).



I'm using a screw and a washer to keep the wheel onto the wheel adapter as the truggy axle comes with a thread. I realy thought i will loose my wheels while driving but this never happened.
