Serum,

1) Not sure what you're referring to with respect to the edit button.

2) The price of Ti barstock ABSOLUTELY plays into the cost of the final product as well as the machining which is no more intense but does require special cutting tools, lubricants, and machining speeds as I previously mentioned. This also drives up the cost since Ti is hard on machine tools.

3) Flex in the diffs (cups and cases) does in fact play into their early demise on high power maxxes. Improving the quality of the diff gears & pinions is always a great upgrade, no question there.

4) The UE gears are very well made but for perfect mesh and silent running you need to lightly de-burr/polish the teeth which have an ever so slight burr from the machining process. A quality lube also makes a difference. I've been working with two major performance oil manufacturer's on a lube for RC transmissions (thru my drag racing & NASCAR affilliations). I may market the product at some point in the near future. It's in beta testing right now.
