I am terrible at soldering, but fortunately my solder joints seem to work. I can never seem to get both parts to heat up at the same time, and I often fear I am holding the heat on too long. Usually the wire is burning my fingers before I can get a good solder joint. So any tips would be helpful.
The GT3B is everywhere. Look on Amazon
Or if you want ABS, the GT5 has that.
Or if you want a really nice radio, look at Futaba. But bring your wallet 😉 But those Flysky radios are the best bang for the buck.
That servo is more made for monster trucks and truggies. The speed is .12 @ 8.4v, which is ok, but not great if you're gonna race it, which based on the tires you have selected I assume you will be. Look for something around 250 oz/in torque at 7.4v, and <.1 speed at 7.4v. Just my opinion here...
That particular servo is out of stock everywhere that I looked except that last one on Amazon. There are lots of servos that would do good in it. But you didn't seem to have a budget, and based on the last Tekin servo I just installed, holy hell they super nice.
The Associated buggies have always been some of my favorites, but I never owned one of their 4wd buggies. But the 2wd versions were always just so darn quick and nimble, I can't imagine they would drop the ball on a 4wd version.
A kit is far superior to any RTR out there. There's no real reason...
