Dps, I'm assuming you are talking about the $20 dollar sim that comes with a TX. The TX that comes with the Falcon has a serial port cable which comes with the Falcon that you can hook to the computer and download FMS simulator for free which is the exact same thing as the sim you ordered. I'm not telling you this to make you feel bad but you might be able to get a refund on the sim if you don't open it. If you do decide to use the Sim you ordered or go the other way both can be a pain to get working on the computer. You will need to download a program called PPjoy it is also freeware and is what allows the TX to talk with the computer. It can be a pain to get setup but it does work good for learning your tail in, side in and nose in orientations but not much else. If you have trouble with the settings just let me know as I have them written down. If your running Vista I have heard of people not being able to get it to work, I can't help with Vista as I am still running XP.

snooptalian, thank you for the RaidenTech shipping tips and codes. I used the "free shipping" code while ordering yesterday (19th) and have recieved a tracking number in an email that my Falcon 40 is scheduled for delivery tomorrow (22th),, Not bad!!

Pinions are a piece of cake to change if you have the correct tool. I change mine back and forth between 9t, 10t and 11t all the time. I do this in an attempt to make the brushed motor I am using at the time as efficient as possible.
Is this with the STOCK motor? It looks like a press/interference fit between the pinion and the motor shaft. 'Cause if I can, I'll change it to play with more parameters.

Dps, sure you can learn without a sim people do it all the time. The good thing about the sim is when you crash the heli and you will you just hit reset button and start over, no digging into the wallet for parts, waiting for parts and down time which sucks.

Dk, yes the puller works with any motor with a press fit pinion shaft. It even accomodates different size shafts and pinions so it is a tool that can be used in other places than just the Falcon. USHobbySupply sells it for $12.99 which is where I got mine and it is a quality tool that will last a long time. I highly recommend it. The tool will pull the pinion, to press the pinion back on I just open up my vise and place the pinion and motor in the jaws and slowly tighten the vice. It presses the pinion on very nicely.

DPS - You can absolutly learn without the sim. I have never had one and only ever use them when I happen to be in my LHS where they have G4 and realflight set up. I am about the same level as Dave in that I can tail-in and both side in. Haven't got to nose in yet but am working that way. I have also started taking it outside for some forward flight. the falcon will break but it is extreamly durable little heli. In minor crashes you can mostly straighten the blades and go again.
Dave a pinion puller is great. I picked up one at my LHS. It's GWS brand. Its very compact, a sinch to set up, has 3 different size shafts for diffferent dia motors and pulls pinions like a dream. It was also 12.99. I press new pinions with my bench vice just like bones. I have a 9, 10 and 11t to experiment with. Pick one up you won't be sorry

Oh, cool! I love datasheets
Let's see:
Motor diode: 1N5819 8 bit microcontroller: EM78P458 (OTP so you can't read it) original MOSFET: FDS4410 N-channel my replacement MOSFET: FDS8812NZ N-channel 5V regulator: LD1117&xx LDO Op amp: LM324
PM me your email if you'd like me to send you the datasheets.
Output to the motors is a 2.05kHz (488us) PWM signal (kinda high!), varies from 0-100% duty cycle The piezo gyro outputs a deltaV based on the rate of rotation. The op-amp brings the signal up to 1.6V steady state, twisting the board causes the voltage to either rise above or fall below the 1.6V mark.
Initial take on, "What does this pot do?" Not much! Setting the throttle to 1/2, and setting the pot to 0.5V, I got a 174us pulse (~35.6% duty cycle). Keeping the throttle at the same place, and setting the pot to 3.3V, I got a pulse of 182us (~37.3% duty cycle). So it doesn't change things by much, and it seems to increase the duty cycle as you lower the voltage from the pot.
And one more thing, here a postmortem picture of my tail motor, you can see the missing five fingers (well, actually you can't!) and how, on the other arm, the fingers are almost warn off.
