I chose to keep the stock 7t to see how good it flew before I start changing combinations. The one thing that might be a problem going 1.5mm is there might not be much meat left on the pinion to keep it from spinning off (even with loctite). Worth a try though. I think the C05 might give the same flight times since that motor was always pretty efficient in my MCP's and MiniCP's. I might have to go with 8t with that one. Going to give a try and see what happens.

People want to upgrade the LG on these things? Darn, I've crashed mine more times than I can count and haven't even come close to breaking the landing gear (or anything, really). Not to mention the landing gear is such flexible plastic, and replacement cost is dirt cheap. Am I missing something?

Picked up three more of the oem batteries at the LHS today. For $5 i might as well. The heli has so much more juice with these over the 130mah 25c turnigy's i have for my msr/sukhoi xp.

I also can't wait to upgrade this thing to BL... For $60ish you can't go wrong, will be a ton of fun and def. worth it.

Yeah i noticed missed that when i read your first post

On the 8 tooth you can buy 8T m.3 with slip fit for 1,5mm

I have drilled a few pinions out myself but without a drill press it has been a bit of a PITA

Let us know about the co5..always loved that motor just thought it might take a bit too much uumph. I have a hole pile of them here too so if it works ill convert my other one to c05m instead of keeping it stock as planned

I broken mine but hot glued them and since they have been good. I eat the heli out of mine though..harder than most. I think the real stresser was at my office and all the pavement drops..

Yup but for those of us who dont you can get the BLHeli flash usb for cheaper than the tool stick itself pre conversion I almost converted my own (found your awesome site sometime ago) but I couldnt find the stick for less than $19

That is weird...both of mine were bnf versions and neither required anything other than a standard bind with the button. I also just tried binding via the software when I pick a model and that didnt require any stick command either

My guess would be that all come preset with the heli doing the curves and some of the bnf helis they forgot to switch over
I missed the right rudder step when binding to my dx6i and it veered left and to the rear on takeoff and was hard to get under control. I rebound it properly and now is like a different heli. It lifts properly to a stable hover and is way more controlable like my mcpx, mqx, msrx and 130x.

Ah, those were the early days of BLHeli. LOL It wasn't that long ago either. I just saw the toolstick offered by Dylan. Sweet! That's the way to go.

I will, thanks for the info. i let play with rf 3.5 but he gets bored with it. He said if i let him fly my H9 B-25 he wouldn't get bored. Ha! Umm no son....

Did you hot glue before you broke them or after. Thanks

This is from a few days ago - the point I've got to reading through this thread - have scanned the rest ad don't think it's been answered properly, so I thought I'd clarify things...

You have got to be kidding me $45 bucks for a parallel hook up.....and I thought a $6 feathering shaft was ridiculous.
Actually it's not a parallel hookup. It uses two 1s lipos in series, so the input is 8.40 volts, and a voltage regulator to bring this down to 4.20 volt, which then is supplied to the receiver. The advantage seems that you will have full power throughout the full flight, and not just the first minute. With a single cell the voltage under load will sag below that 4.20 volts easily and even further as you fly longer. With 2 cells parallel the voltage sag will be less, but stil there. With this "booster" the voltage will remain 4.20 volts, until the lipos are drained.

One drawback though, you can't trust your LVC with this, because the output voltage of the booster will only start to drop when the 2S battery, you make with the two 1s standard lipos, have dropped so low that the voltage regulator can't produce a steady 4.20 volts any more. By then your lipos are on their way to lipo heaven, or hell.
ahha.. well still the only difference in construction is a wire cross and a diode. Similar to how you drop an ar6400 brick 2s brushless conversion down to 4.2v for power supplied to the board.

Basically if you dont rely on the circuit board to hold the batteries to the heli you could do a simple series wire adapter with a diode on the lead right before it feeds into the rx and it would do the same thing. If this is something you wanted you could buy a double battery holder like Dylan sells, or make one and a buck or two in parts from HK, Radio shack, or digi-key and have a "booster"
Except it's a lot more sophisticated than a couple of batteries wired together with a diode, as should be clear if you look at the pics, and even more so if you read the text - Google does a fine job of translating:
"During development of the booster has been taken to achieve the highest possible efficiency in order not to waste energy unnecessarily (flight time).
...
The booster is a simple low voltage indication that a red LED indicates the lower voltage limit of the batteries as soon as they flicker already slightly begins should landed immediately be. Additionally switches the converter upon further below the battery voltage to the output from hard."

What you have there isn't an inefficient diode drop - which will waste almost half the power in you batteries, and won't achieve anything like the quoted 7+ minute flight times - it's an efficient switch mode buck converter which will be ~90% efficient. That's along with a low voltage warning and a low voltage cutoff for the batteries plugged in, so that you're not relying on the one in the heli (which as pointed out won't work properly with this booster), and won't destroy the batteries even if you forget to time the flight. Not at all something anybody could make - I have made things like this, and off the top of my head, the parts alone when bought in small quantities would be ~$25, so not really that expensive at all for what it is. I'm sure if I was interested I could make my own, and maybe even make enough for it to be worth my while selling at $35 (given my low hobbyist overheads), but I doubt there's the demand for me to bother.
