My rev 5 seems just as stable as the rev 3.

Btw, it seems the rev 5 has some limit on the charge current. I always time charges to get an idea of how much has been drained from the battery. The rev 5 has been charging for over 55 minutes now, even though I didn't fly it until it could not stay in the air. On my red one a typical charge takes 35 minutes at most, often even less. I use the same USB charger for both, the one that came with my rev 3 one.


Edit: left turns are a bit faster than right turns on the rev 5 bird. With left turns I can make it pick up some speed after the turn. Still not as fast as the red one, but it makes flying it more enjoyable.

I had one that had really bad pendulum and oscillating motions that I just couldn't enjoy flying it so returned it. the replacement did not have this issue.

Seems like the longer charge times are not caused by the USB charger, even with the charger that came with the rev 5 bird it takes much longer to charge the battery, even though I didn't fly it very long. Flew the red one just as long, and this was full after 35 minutes, the yellow rev 5 one has been connected for over 45 minutes and is still charging...


Edit: same flight time, but on the rev 5 bird it takes 15 minutes longer to get the battery charged again. Also, the led on the USB charger doesn't shine as brightly to indicate full battery, it's more like a shimmering light. Perhaps they did this to make sure you see the difference between no connection with the heli, and battery full indication.

Is This My Board?

OK, I've been reading your posts on the two boards the S107 can come with. I shined my flashlight through the side of my 107's metal frame, and towards the front, there is printing on the circuit board that reads, "S107R3". Does that indicate that I have the "3" version of the board?

Oh, and closer to the center of the board near the spur gear, it says "RoHS" encircled by an oval mark.

Hey, all I want to do is to learn.

Cheers,
Ed

Thanks for your answer. I take it that your enthusiasm means having the revision 3 board is a GOOD THING!

My rev 3 has much faster control than my rev 5 and longer flight times too. Both fly well, but the rev 3 is just more agile, especially on turning.

I find My rev 5 turns slower CW than CCW
The REV 3 firebird turns alot quicker in both directions than the s107 I have.

I Flew My S107 Outdoors For The First Time

Since the sun was low in the horizon, and there was almost no wind, I decided to chance flying the 107 outside while my lady friend and I were sitting on our lawn chairs on the driveway.

I had a blast flying the thing around with no fear of colliding with anything. But when it got about 15 feet away, it would start to lose the IR signal from the transmitter.

There was still some sunlight, and though the sun sets in opposite direction to the front of the house, and we were in shade, I think the clouds east of us, were still reflecting enough sunlight to interfere with the 107's reception of the signal. I didn't have any trouble dealing with the light breeze.

Now I'm wanting to get an outdoor helicopter in a bad way.

Cheers,
Ed

Good. It may be worthwhile to replace any worn/damaged parts unless the board itself goes.

Happy flying...

This is from a blue S107 I bought earlier this month.
Thanks; now I know what to look for as it does appear that the board is laid out completely different than the Rev. 3's....

I just got the office shipment in (18 units) so I will ask the owners to check which ones we have in this group. All three of my S107s, a Firebird, and a replacement board I purchased are all Rev. 3s.... I wonder now if the Rev. 5s were just another supplier and Syma recognized the inferior design and went back to using Rev. 3s?

Just checked mine out after a great couple more flights. Both my birds have the R3 boards.

I noticed with fresh batteries the Tx range is much further, i got about 30 ft range with brand new Duracells

It's always like this. That's why I started with a S107, then a S032, then a Firebird and now with an Esky Lama V4 Orange and a Honey Bee Fixed Pitch V2.

Yeah, these IR transmitters eat batteries like nobody business! That's why I got this special battery charger; it is new technology that recharges regular disposable AA or AAA alkalines; I've been using it now for about a month and it works great and has saved me a bundle in aa batteries:

I got my first one when it was on sale for Sale for $20 and free shipping but recently it was on sale again for sale $24 plus free shipping; picked another one. They just came out a new model that also does C, D, and 9V batts:
