I agree with you.if you can not adjust these trims well,you can't keep the heli fly steady take off at all.When the body lean left,you should adjust the crab trim right,and when the body lean right ,you should adjust the crab trim left.The backwards and forwards adjusting is the same way.If the flight can't last long,make sure that the battery are charged fully.The most important is that you'd better operate your lovely bird after adjusting all the trims well.If you do not adjust it well at first and hard crash many times,I can't make sure that your heli without any damage.

I'll try to get my order cancelled by Banggood. If they credit my PayPal account, I'll order from the link you provided.
I asked Banggood for a refund.

I got a notice from PayPal, a few hours after my email request to Banggood, that my credit card charge had been refunded.

Although I haven't received any goods from them, yet. Banggood's service seems pretty responsive. I'll look into purchasing items from them after the Chinese New Year.

The problem doesn't lie with the batteries. I used the same batteries on my second V911 and it managed to return about 5 minutes of flight.

And I do not have a spare main motor to try out as well. Do motors wear out that easily now? Mine doesn't even clock more than 20 flights. I had my Solo Pro close to 2 years already, clocking countless of flight time and had not needed to change the main motor yet.

So I just got a shipping update. Hopefully it will make it out before the holiday. One other thing i was wondering, is it feasible to say that a solo pro landing skid can be retrofitted to this heli? They seem to be very similar, and may be a light modifiable fit. In that case, it would make it easier to source additional battery options from the solo pro threads.

Drip some lubricant down the motor's shaft. It lubes up the bushing and does help.

Motor shaft? You mean from the part where the motor pinion gear is? I only have WD40. Is that suitable as lubricant for the motor?

Yes, from the pinion side with the heli upside down for a minute or so.
Rotate the gear too, to allow the lubricant to ingress.
Use Triflow or bearing oil when possible, but wd40 is better than nothing.
It's main use is as a water displacer.

I wouldn't use WD40 as it is so volatile and will be dry in very little time.

Thanks guys for the tip. I'll probably test it out with WD40 and see if it does help. If it doesn't correct the problem, I may have to replace the main motor.

Just curious, is there any way I can replace the main motor without soldering? I have very limited experience with soldering and the last time I tried to solder wires, I ended up burning my circuit board.

Some motors use "brushes" that are just thin strips of metal (Walkera 4#3B). Others, (Blade MCPX) have motors with proper, carbon brushes that will last a long time.

Take one of yours apart and let us know if they've gone the cheap route here.

Clip the wires from the old motor. Install the new motor and clip those wires. Then, solder the wires from the new motor to the wires coming off the board. Much easier to solder wires together.

But that means you need some very small heat shrink tubing. OR, stagger where you clip the wires to prevent them from shorting out, one to the other. A dab of silicone glue on each solder joint would work, you can even "marry" the two wires together.

yes, both helis are stock. the v911 yaws a couple of times faster than the 9958, it allows for much harder flying.

Did you have the yaw set to the high rate by pushing the left chromed button on the TX? Even on low yaw rate, it spins like a manic. .... LOL

Ok, so you have a nice stable. Can you comment on compatibility of batteries and chargers?

Will any Turnigy (V1, V2, TREX) fit into the V911 and it's charger unmodified?
If I bought the battery connector, could any of the Turnigy be reworked?
I'm really eager to get something with a bit more punch that the stock battery.

Any suggestions, anyone...
