RE: switching engines
Yea you are cool, mein freund, nobody is hating on you here. You should however understand that the toy grade ones are just that: toys. I would drop them and get even just a cheap hobby-grade RC. No need to go big money or full flash, either, especially for your first kit. many companies offer great beginner vehicles for a fraction of the cost you listed. the plus side, as well, is when you run hobby-grade, breakages will not stop you for good, you can just buy replacement parts! I am unsure of your budget, or i would be better able to recommend you a good starter kit.
