What other 4CH's have you tried? Tell your story!

On a side note, what's the difference with the R12 board? I have an R3 which piros very fast, I heard they slowed that down with the R5, just wondering how the R12 is different?

Just out of sheer curiosity, what is the average life expectancy of a 107 in running time. Not referring to crash damage but just from general wear and tear. Just wondering of how long I have before investing in a new one for when this one gives up the ghost.

I'll have to get this story together to post it. Suffice it to say these are flimsy 19 gram birds with cowling/fuselage and "tail feathers" made of very thin brittle plastic.

I was warned off both, only after purchase and before delivery though - doh!

One has never worked, puffed battery day 1 (going to substitute an S107 LiPo when I get to it). The other is new today and similar... but flies at least. Tail feather snapped already (scotch tape for now - lol) but it seems to desperately need forward/back trim and the TX only has Left/Right trim control. The tiniest indoor breeze from forced-air heat here can throw it wildly left, right, back, or to the ceiling. I have not yet navigated it through a doorway w/o incident.

Of course a big piece of the puzzle is that I'm only used to 3CH flying too. These were meant as cheapie "basic trainers" for 4CH operation, but I'm not sure they'll make it.


As far as I can tell so far the R5 works just like the R12, though the R5 might possibly be a teeny fraction "peppier" I suppose. I need more "hours in the cockpit" on it to say more.

sometimes it can take several flights to break them in, i had another non syma bird that took over 10 flights to break in as i was getting barely 4 min of flight on a 180mah lipo out of the box until it broke in fully, and its not just the gears but the brushes inside the motors that need some time to become rounded and friction-free... i read the other day that these brushed motors consume significantly more juice from the lipo before they are broken in.

hard to say but assuming your lipo doesn't cave in. next weak spot is the actual motors as those brushes inside wear out... in my experience on one s107 i started feeling decrease of power after 60-70 flights on another after about 150 flights.

Depends on how often you fly, how well you look after the battery and helicopter (by allowing adequate cooling periods etc) and what condition your helicopter was in from new. Sometimes you get a dud battery or motor right out of the box.

If you fly many times a day, every day, I would estimate about a 3 month life expectancy before the battery dies or a motor burns out.

If you only fly on the odd occasion, perhaps two or three times a week, it's not uncommon to get 12 months plus use out of your S107 assuming you take proper care of it.

I'll bump this thread, it has important info, but I just got my heli, is flies great, I've limited myself to 4-5 min flights. One question, can I replace the stock battery with another s107 one? I see they sell for $2 on ebay, kinda good deal instead of buying another heli eh? It states that it comes with the pcb soldered already. I'd like to have a honest view on it, since instead of buying a same heli, I could save up the money for a 4 channel one or whatever and keep my s107 in action. Your thoughts?

you don't need another lipo if you are flying 4-5 min and taking care of that one you have it should last you well over 200 flights, life expectancy on them is well over 400 charge cycles

Well, look for advice before buying any 4CH. There is some crap out there as I know too well.

You can replace the battery in an S107 and you might even add connectors if you think you'll do this a lot. My guess is something else will give before you put in a 3rd battery unless you're rough on them though.

You can find S107s cheap with some shopping. Call it $15 to $20 depending on whether you get a naked one or one with another Tx in the box. I'm not sure there is a "good" 4CH out there for $45 - but with my experiences I won't claim to know a thing about 4CH units.


I'm not sure that 4CH thing they sell with two outboard fans really qualifies. Yes it uses 4 channels, but I don't know if the flying experience is the same as on other more.... conventional 4CH coax machines.

ordered new batteries

I contacted DWhimore through ebay and arranged to send him a postal money order for five of the 240mah batteries. I will only need three but will do some testing and breaking-in before i install them in one S107 and two 6010's. Have used mail/uspmo's in past with only one glitch (on rcg)

I have a similar helicopter (a 6020, non-gyro) that has lasted me 2 years so far and I've only had to replace the flybar once because it broke in a freak crash and the lipo once because one day I decided to fly it til it could no longer climb. I keep my flights under two minutes and always charge it before each flight. I don't know how many flights its had but I used to fly it 4 or more times a day when it was new so maybe a couple hundred all together.

It'll be sad to see it die! I'll monitor it then, I'm already on 10 flights in 2 days, so exciting. But I respect the cool down period + 5 min flights.

I was thinking about something in the Solo Pro line. Looks pretty good and costs a tad less than some other helis. Either that or I'll go for an Msr, I see it comes at $100 BNF since I already have a Tx that came with the champ.

Thank you.

I didn't even know Donnie sold bulk batteries. Were they reasonably-priced?

Hmmm...new heli is going to be a tough sell to the missus. She is hesitant to support my new obsession. I'm thinking a couple new motors may be a more discrete acquisition, shall we say?
