Visited Champ R/C
I'm on a business trip in Tokyo and stopped by Champ R/C in Akihabara. I'm amazed by several things.
First, the selection of parts is remarkable. I have an HPI Pro4 and the store has every HPI part and most aftermarket parts. It also has parts for Yokomo, Tamiya, Associated, Hot Bodies and a few others.
Second, the prices on the HPI stuff are at least 20% lower than in the US.
Third, HPI sells lots of really nice hop up parts in Japan that are not available in the US. For example, I got a carbon fiber drive shaft and upper bumper brace as well as alu spring supports and damper end balls.
In addition, I got a set of IB 4200s (not matched) for the equivalent of $40.
It was fun visiting the store and I may go back again to see if there is anything else I "need."
