RE: What problems can I expect with aluminum upgrade parts?
Okay no problem.
I can understand your being upset if that is the way you feel.
Let me tell you how I feel though... Being the owner of a Tsunami. It is a great car. It can in no way be compared to Radio shack.
Mine has broken twice because of the surface I am running it on and most importantly becase of the amazing power it puts to the ground with the upgraded motor and the best nimh batts that money can buy. I assure you that there is no one that would look at this thing run and not be impressed! Yes they are inexpensive... but that does not make them cheap. A few upgrades (that a lot of people do anyway even to the more expensive cars) will have a RTR Tsunami putting smiles on faces of all ages!!!
