I can't get the VRC link to work but there was a previous version of the usb adapter and then the new one. Some people have had issues with the newer one when using a futaba radio. I don't know what the fix is but you can see it on their board.
As for helping. I don't really think it would hurt any. You are still driving an rc car. You still need to know when to lift and when to turn the wheel. You are still exercising your mind when you drive and keeping the eye hand coordination going. So imo, I don't think it would hurt as it would be better than doing nothing.
There is great need for a sarcasm font.
You never know when it will strike, but there comes a moment at work when you know that you just aren't going to do anything productive for the rest of the day.
Sometimes I post just to look at my avatar.
