RE: New Radical 621T .21 Off-Road Engine
Hincappe you have a right to talk about other hobby suppliers however my experience with RCMart and the other Chinese disti's is that yes they are cheaper but shipping can take two 2 three weeks and forget about returns. In the US i would never buy from them again. Nitrohouse and Amain get you parts in a matter of days, not weeks, and they answer the phones and you can understand them.
As far as the engines go you simply cant say they are overpriced until you buy, break in, race for an extended period of time, and put many gallons of nitro through them. Time will tell. In the interim it looks like there is good feedback on these mills. there are many italian and now mugen mills in this price range - i for one am glad there is more competition to keep making them better and offering us racers more choices.
