The upcoming availability of Spektrum modules is making me think about getting a new radio. I've read this entire thread trying to understand the pros and cons of the Helios, and still have some questions:

1) Why does KO USA not provide the manual as a PDF? Other manufacturers do: See for instance http://www.futaba-rc.com/manuals/index.html .

2) Is it true that if some of my models can use Advanced HSR and others use Super HSR or normal rate, I must physically remove the module and flip some switches in order to change between my models? Given that many Tx problems reported on this thread were attributed problems with the module connector, it seems like a really bad idea to be constantly removing and replacing the module.

3) What value does the computer interface provide other than more convenience in loading tones into the transmitter? (And the ability to program servos -- something that nobody on this thread has said they've done.)

The value I'd most like to see is the ability to use the transmitter as a PC game controller -- is this provided?

I'm compelled to observe that PC serial ports are a legacy technology that many future PCs will not support. It would make a lot more sense for the transmitter to support a USB connection.

4) What level of technical cooperation is taking place between KO and Spektrum/Horizon and KO in the development of the Spektrum module for Helios? Does KO share technical information with Spektrum/Horizon on the module interface, or is Spektrum/Horizon required to reverse-engineer this interface?

Cheers,
