How do you know when you need a new motor? I got at best 10 flights on my mCPX and now it just seems to be bogging big time. Even with very gentle collective inputs it still bogs and loses the tail in simple flips and rolls. After 1 minute I barely have enuf power to flip it inverted with both my batts.

try reducing some pitch,the eflight batteries are ****.i bought 5 batteries and after five flights 3 are alot less powerful.i went to the hyperion 240,they are a lot better.i get about the same flight time but much more power through out the flight.their could be a chance your motor is bad,but try flying some more with less pitch and see if it gets worse or stays the same.if it stays the same i would bet on the batteries.

No I was pretty happy with it initially, very little wobbles and some collective pop with a solid tail, and it sounded healthy, now it bogs and wobbles just climbing out or accelerating. I picked up a Hyperion 240 I'll try that before a new motor. I've had a lot of heli's and some underpowered ones, this feels like when the rotor speed slows too much giving the wobblies and loose tail, but then again the tail is not driven by the main motor on this thing but by the battery so it could definitely be weak batts...

Maybe your charger is going bad? Sounds like your mcp is short of juice with both main and tail motor going weak at the same time. Could also be something binding, but there are not much that can bind on these helis

Mine does decent rainbows and piroflips the first 1-2 minutes with the stock lipo. It will do stationary flips, slow funnels, fast ff and easy collective stuff till I land it at roughly 4 minutes.

If it doesnt work, throw money at it...

Now that's something I'd pay money to see.

My buddy had one that flew poorly. It was actually the tail motor that was bad. We changed it out and its a completely new machine. The tail motor was robbing all the power from the main motor making it bog all the time.

That's pretty crazy, cool you found the solution. I'll put it on my list of things to try. Align 250 would be cool, I used o have a Hornet, you basically glued it together, fun to fly but had a tendency to explode in flight I'm just a sucker for these little Blade heli's. Can't resist em.

I had a Trex 250 and you do not want to fly it in a house unless you have a big basement or have access to a gym. Mcpx and a 250 are not in the same category. It is nice to have a collective pitch to fly in the house that that wont break things.

Got to have my cup of heli in the morning.

I've had to replace a main-motor already (somewhere around 20-flights), if it's the motor you will know soon-enough, it will give the sound of a spent-bearing just prior to seizing. I even went as far as to run it in distilled-water (to revive it), it came-back but, only for around 2:00 of 1-flight

Now running a new-motor (stock) but with 9T. pinion

What is the stock pinion and how is 9t an improvement?

Gardner is correct, stock is 8T.

I got a few-flights in with mine today on the 9T. pinion, it definitely has more Headspeed (which helps imo) but, I really need to try running with the Hyperion 240mAh Packs (currently running with the E-flite 200mAh Packs).
I've read that the Hyperion's are much-stronger than the E-flite's

Have you been oiling the motor bearings? This is pretty standard on brushed motors they can start to heat seise, talk to any car guy about oil.

I was reading about this (oiling), from what I understand, to actually "get-to" the bearings, you need to open-up the motor-can (?)

Do these motors even use a bearing(s), or, is it more like a collar-type piece (?)

(Guess I need to open-up the old one )

I picked up a 240 Hyperion but you will need the male connector from an old stock battery to use it, it comes with the male small connector on the battery and a female plug for that which you solder wires and a large eflight male connector from an old eflight battery.

Thanks, yeah I need to order a few things once I decide to make the move to the Hyperion's, right now I really need one of those parallel charging-leads (squid) so that I can charge all-3 of my E-flite Packs (at the same time) using my TP 1010C

I did see where someone had installed a Brushless motor/esc set-up in their's, I need to check back and see how that's workin' out for him. Having a constant HS throughout the entire flight would make a world of difference (to me)
