Hey Peter<div>Here's a couple of videos. If you have any ideas or need a video of trying something, let me know. Gonna try upload videos now.</div><div>

Hey again Butch,

Its times like this that I wish I was next door to you - I could have that bird running in a matter of mins.....[sm=tongue_smile.gif]
I think we can get this going for ya before your hand surgery mate

It looks to me like your inner shaft is not severely bent - that's great news!! (*phew*)[sm=52_52.gif] - but the screw under the bottom gear may not be tightened into the slot to stop it having slack......[sm=50_50.gif] To check this (with everything turned off - remember safety first!) grasp the head with one hand and try to stop the gear moving with the other - remember that the inner shaft and bottom gear drive the upper rotors (so the top gear drives the outer shaft up to the lower rotors[sm=wink_smile.gif])
The upper & lower rotors should begin within a couple of Tx clicks of eachother - but the top rotor will always stop spinning last due to the centrifugal forces of those weights at the ends of the flybar[sm=teeth_smile.gif]

That beeping sound is the electronics trying to tell ya that something is wrong That being said, my new BOL that I have just removed from its box has a similar sound - but quieter & solid - not "morse code".....this confuses me a little[sm=what_smile.gif] I hope that the correct spinning up of the rotors eliminates the "noise prob". Fingers crossed.
The red/green/red/green/red/green light on the side of 3in1 after you have switched off the Tx in the third video (the outdoor one with canopy on) just tells you that the Rx has lost signal - and is normal with the Tx off.....![sm=49_49.gif]

Read these instructions all the way through - and ask any questions before actually trying it:
Try this: Mark the top of both motor plugs with a marker - a dot will do! Unplug the top plug - hold it in one hand and unplug the bottom plug with the other hand. Plug the first (ex-top) into the bottom slot after "twisting" the plug upside down to reverse the polarity. Plug the other motor wire (ex-bottom) into the top slot after "twisting" the plug upside down to reverse polarity also.
Be careful when first spinning up that the rotors are turning opposite directions - the top rotor should turn CCW, and the bottom rotor should spin CW if you are looking down at the bird on the ground.
You wont damage the electronics by plugging/unplugging "hot" motor wires - so feel free to try some other combinations if this one doesn't make the rotors turn the correct directions mate! Just lower the throttle trim tab all the way first and put a large rubber band - attached one end to the steel frame passing around the rear of the Tx and slip the other end over the throttle-stick (this will ensure that your rotors do not accidently spin up). It's an old plank trick....... [link=http://www.youtube.com/watch?v=SloQbpZ8GR0]Here's[/link] a video of someone else with this rubber band idea to show you what I mean - 1'52 shows you how it passes around the back

Tell me how it goes[sm=thumbs_up.gif] (or doesn't[])

Please lube your bird, preferably with labelle 107 plastic-safe oil - it will make it all-over smoother & quieter (& runs for longer eg. I regularly got 9½ mins from a standard Esky lipo)

Peter[sm=shades_smile.gif]
P.S. "hot" means lipo battery plugged-in
P.P.S. polarity changes (+/-) will not hurt your motors - they can spin both directions nearly equally
P.P.P.S. (<- if there is such a thing[sm=regular_smile.gif]) The "flip-flop" polarity of the motor wires puzzles me also - there doesn't seem to be a norm. Three of my BOLs have opposite, and the other one has the same motor wires polarity[sm=confused_smile.gif]
