At a recent run over last weekend I noticed in the pits that the front wheels were exhibiting some chatter during steering. I spent the whole week trying to find the source of the chatter only to realize later that it'd probably been there the whole time. Car seems to go fine on the track but when throttling and steering on the bench the front end vibrates. Did some reading and it seems it's normal for universal joints to do so... week of troubleshooting wasted. lol!
One thing I've noticed with the FF is that tire selection or condition is less important compared to a traditional Rear Wheel Drive (RWD) buggy. On a RWD buggy, especially when tracks get looser, the tire choice can make the difference between a good handling buggy and one that can't even get round the track. On a FF however, even worn tires will work decently - of course a good tire will generate even more traction, but the performance gain is not as significant.

Track testing update - 8.5T motor!
Over the past week the buggy has been in the hands of various drivers on the track and their comments have all been positive, but one thing many said was that they'd like a bit more speed in the car. At our local track the 10.5T I was running was pretty fine for most of the track but at the triples it needed a very good line to clear all 3 jumps at a go... I had to admit that I thought with a faster motor I would be able to clear the triples with less effort and thus knock off some seconds off the laptimes.
Yesterday I had some track time after installing a 8.5T Tekin Redline Brushless motor in the buggy. How did it go?
WOW did the new motor add some zip to the car! The triples were much easier to clear now and that was the one part of the track I would lose a bit of time on if other racers were attempting the 3.
The car excels coming off turns as it one doesn't need to feather the throttle - in fact I found myself having to back off the throttle quite a bit when coming up behind cars (to avoid hitting them) as very often the FF buggy would be able to carry more speed in the technical sections of the track.
At the end of a 30 minute test run the motor and ESC were both very cool at about 120 degrees farenheit.
So far so good.
