thanks - weight is concerning me as well, she'll be pushing the main motors close to the limit. The best way to go is probably with 6020 running gear. You can strip off a lot of dead weight from these, and the motors/PCB/battery were all intended to lug around 40g. I did a max lift test with a 25g 6010 by taping a 15g keychain to the skids. With a fresh charge and WOT it would veeeerryy slowly descend, so if this one's motors are equally strong she should be able to make at least short sorties at ~35g. All sorts of fragile body parts are likely to break in a crash so I will NOT be attempting any stunts with this bad boy

Killbucket or others - I know there's a picture out there of a S107 PCB with all of the terminals labled, but I can't find it for the life of me (even looked through what I beleive are all of the S107 pages on KB's site). If you have one handy could you please post it here? THANKS! I'm strongly considering ditching the 6010 drivetrain in the Wessex conversion for a spare 6020 one I have laying around. After stripping all of the useless bits it's within a few grams as the bare-nekkid 6010 (15g), but has chunkier motors for more lift (at least 40g). I'd like to swap in a S107 PCB I also happen to have laying around for it's smooth control response, but don't have a spare S107 dissasembled to make sure all the wires go to the right places... cheers!

This would be the one you're thinking of... Although I seem to recall that my LED lines were attached underneath the board. If my memory is correct, there are places marked LED- and LED+ for that.

Thanks Alfa - that is the one! Before I saw your post yesterday I took apart one of my S017's to check. The LEDs are indeed soldered to the bottom of the board. Funny that the gyro on the "spare" S107 PCB is different than the one installed in the S107 chopper, everything else is the same. Hopefully it works as well as the other! Progress on the Wessex: - ditched the 6010 drivetrain (including tail motor) in favor of an extra 6020 I had with a bad PCB. The trimmed down 6020 main rotor parts are suprisingly very close to the 6010's 15g, and the larger motors should be better able to motorvate this big momma much better! Did a preliminary balance; hopefully the heavier 200mAH battery I have on the way will move the CoG forward enough. Prior to reinforcing the tail section did a glue test with Testors Model cement, SuperGlue Gel, and 3 for $1 Harbor Freight "SuperGlue". The suprise winner was the cheapo HF glue! Snapped the plastic piece in half before the glue-bond broke.

S107 PCB all wired up! Main and tail rotors work, LEDs function, it all fits in the fuse and now just final fitting and wire routing before her 1st flight. Final weight will be comfortably under 35g. Still waiting for the S107 blades and 200mAH batteries, but will try her out with the 6010 paddles and 150mAH to check the CoG.

The Syma 3 channel S107 mini helicopter comes in a variety of colors, including blue, red, and yellow. The controller has three primary parts: two control sticks and a central knob. The leftmost control stick accelerates the propeller, sending you up or down.
