We only had two flying since there are only the two channels. PRetty fun though. Have to be careful not to get in the other helis wash. Does fun things to your bird! Tests how quickly you can recover from sudden downward pushes on the heli. Got some work done. I considered it a team building exercise lol

OT request


Hey guys and gals,

I was wondering if anyone in here has a dead s013 black hawk the would sell/donate the top rotor assembly with stabilizer bar. The set screw stripped out on mine and I can't get it to bite for anything and I can't get the rotor to glue on and stay.

So if someone can point me to place I can get the part, or if you have the part you can sell/donate... Or even if you have a fix idea. Please PM me.

Thanks

Something that's worked on other items where the screw has stripped is to put a small drop of CA on the end of a toothpick and poke it in the hole and continually rotate the toothpick until the CA dries. Then take the screw to cut new threads.

If you think the toothpick might get glued in, coat it first with some Silicone lube or light oil.

Has anyone measured the current to the battery using the S107's USB charger?

If so, what is it?

(Not going to leave that first question hanging... Sure enough someone would would come back with just "Yes." and let it go at that... )

s107 - one tough bird


I have crashed this little bird quite a few times and it just keeps on flying. I was flying it upstairs from the basement and it got sucked up to the ceiling ... flapped its wings a couple times .... fell 15 feet onto a banister and bounced down the steps. check out the bent LG in my pics (quality not great, taken with blackberry.) I dusted it off and it flies just fine, got a 9'45" flite out of it after the crash.
I also took it outside at dusk last nite and there was more light out than I thouhgt b/c the controls quit responding a few times. One of those out of control flights took the heli into the gutter where the blades just kept on going like it was going to drill thru the gutter .... whack, whack, whack, whack, whack after a quick clean up, it kept right on flying
a well-made bird for $30, cant beat it.

I've flown it slam into a door jamb, into venetian blinds, and outdoors at dusk. All without incident. I'm so impressed with 107 and its hangarmate Firebird, for the first time since I started helis 18 months ago, I'm NOT in the market for another one.

Right this minute. But I do have my eye on an unreleased Esky. Triaxis gyro, triblade rotor, in the $180 price range. If I DON'T buy 6 submicros, it's free!

Well a usb port is around 5v. On your cable theres no converter, so i guess that its 5v.

Well, I finally took my S107 apart and found the faulty part. It is indeed an H-Bridge that is fried. Looky here:



Google has found me nothing, so maybe someone with electronics knowledge can find me an alternative to a "ML5" H-Bridge. The fried one is the one on the left... the one on the right, is supposedly not fried.

Got my S107 today as an replacement for an SH 6023 which was out of stock. Very stable and rigid on the controls. Although it did not came in the original box but a simple styrofoam box, a little rattling but otherwise intact. Next task will be the analysis of the IR protocol of the TX in order to replace by something else.

Here ya go. http://search.digikey.com/scripts/Dk...ML5103PBFTR-ND

They're not bridges by themselves, they're just FETs. Fact, no idea how they're implementing H-bridge with just two elements. It takes 4. In the H, the crossbar represents the motor, the tops and bottoms go to power and ground, so it takes two switches on to produce either direction.

You may not want to replace the TX, DS. Others in this class are step-encoded, regardless of the capability of the code. 107 is proportionally-encoded.

My order for 6023 was also on indefinite backorder. Certain you will appreciate 107 more.
