Answering Chester's question first:

Currently we are planning to make a small batch of version two units for the end of January. The distribution of these units have already been accounted for, but we hope to be able to follow this with a larger batch of units that will be available probably sometime in April. This date is tentative right now because it depends on what changes or modifications we need to do after the first batch. (However, our expectation is that no changes will be required ....)

Pricing is still not completely firm, but I think it will be in the following range:

Drive: $1,000
Sets of two Props: $200
Gear Sets: $200

Now to Jim's question:

Currently the design is setup so that gear sets are modular, and can be changed at the field without removing the motor from the plane. After you remove the props you can remove six bolts and take the spinner off, revealing the inside of the gearcase. The gear set can then be swapped out and the spinner and props can be bolted back on.

Our thinking here is that with a Contra Rotating System the trim of the plane isn't affected when you change props like it is when you change props with a single prop setup, so it's much more feasible to consider changing prop setups betweem rounds to take advantage of changing weather conditions, (Calm vs windy for instance ...) or maybe to have different setups for f3aP and f3aF, and even if a pilot doesn't want to do this, the option to swap out gear sets makes it easier to more closely match the power delivered to the prop versus the power drawn from the battery pack for a given setup and a given pattern schedule. (Advanced vs masters for instance ...)
