Thanks again for all the useful info and pic attachment showing the 2 locations, at least now I know where to look and what they are for lol

When the weather gets warm enough I will tuck the antenna in and do a range check. It it's still acceptable, I will probably leave it tucked in. The body is already thin enough without having to add additional weak points, where it's likely to fail.

If I can get 400 feet, I will be happy, that's more than enough for me. From 400 feet you would hardly be able to see the car.

I'll take a closer look at the front right wheel to see if there is anything else loose. The wheel nut it appears tight. I don't have the right tools at present for the car (would have been nice if they had at least included a Hex spanner.)
I'll have a look online and what I can get.

Regarding the buggy rims, from what I can understand, not all 17mm are the same. Some are deeper than others, am I correct in my understanding? Or are they all the same?

Thanks again!
