Once upon a time Japanese cars were of pretty low quality but achieved high gas mileage. As such they sold pretty cheap, even after import tarrifs were added to the price. Now Japanese cars are of very high quality, have great gas mileage, and last a long time but are quite expensive. They have captured a large market share and continue to sell well.

Expect similar from DLE. As the more expensive engine makers lose market share the ability of the less capable manufacturers to increase prices grows relative to the decrease in sales of the more capable engine manufacturers. Don't delude yourselves into thinking this will not happen. If not for the domestic and European UAV market the high end engine manufacturers would already be gone and the hobby would have already seen a significant increase in Chinese engine prices.

As a the response to the RCGF warranty issue, an engine walking across the border from Canada hould have the same warranty as an engine sold in the U.S. To suggest otherwise implies a serious lack of confidence by the manufacturer in their product. Probably less confidence than I have in them.
