Don't cut down the tail rotor. You need that thrust to counteract the torque of the main rotor. If you cut down the tail rotor, the tail motor will have to work harder to hold the heading, thus shortening the motor's life. It would only slow right turns, anyway. The resistors are definitely the way to go.

Does anyone know if the large white gear on a Y911 is the same as a V911 in number teeth and pitch diameter, they seem to mesh correclty.

Or if the sub-assembly V911-22 fits a Y911,one shaft is is chrome, one is carbon fiber.

http://www.aliexpress.com/item/Free-...566278916.html.

MyRCMart doesn't carry a Y911, does anyone know where to get Y911 spare parts as I'm not having any success

A few flights with a Y911 and it took some damage, see my blog.

Thanks in advance

Should fit.

I replaced all my fleet (V911 and Y911) with SP Delrin gears.
I measured a couple of each type of gear (V911, Y911, SP): All 1.012-1.015"
I didn't count the teeth, but I bet they are the same +/-.

Both types of shaft (V911 metal and Y911 carbon fiber) are 0.116"

I put "fisheyes" with the carbon shafts in all mine - so that's compatible.

However: Someone yesterday or so posted that the fisheye wouldn't fit on his V911 stock shaft.

I just tried a fisheye on some old metal shafts and they fit for me...

Aliexpress/Firecabbage was my go to parts source, but they seem to have closed up shop.

Banggood told me by email last week that this is the fisheye with carbon shaft: http://www.banggood.com/Wholesale-V9...t-p-49035.html

(you can kinda see the second guide pin coming out at you in the picture and it looks like carbon fiber).

I got my delrin gears here: http://www.miracle-mart.com/store/in...oducts_id=7335

Your real question was where to get Y911 parts. I haven't seen the main gear anywhere.

I agree on getting the 9116 TX at the low cost. The V911 flies so much better with this controller. I used the TX to trim down the rudder and increase the elevator for more forward speed. I also used the subtrim (saves on power off) to correct a slight clockwise rotation from the rudder. I always had to trim this when turning on the V911 TX.

Thanks guys, I'm up and flying again OK it's not rocket science, but for someone whos only previous experience of a soldering iron was about 40 years ago trying to convince his sister she should tell where she hid the chocolate biscuits, it's a step in the right direction

Special thanks to mystman for making sure I didn't have to wait for my parts to arrive from China

I do have one question though. Tinning the wires was no problem, but it took me several attempts at soldering to get the 2 wires to have a good contact and not keep separating. What's the most common "novice" mistake that would cause that? Keepnig the soldering iron on the wires for too long? ...or is it likely that there was some other cause?

Thanks again

I have similar problems, which I think could be partly due to old soldering iron (solder residue slowly collects on the iron tip, hard to keep it clean). I bought a gadget called a helping hand, I hope that'll help in my next repair job. You might consider getting one, $12 from eBay.

I twist the two tinned wires together like RicksterRC said.

Twist together and solder.

You could also get a soldering station with clamps. I don't have one. Kinda wish I had one sometimes. I figure by the time I mess with that I could have twisted them together. I no expert though so maybe someone else who is will chime in.

Cheers, must've overread the twisting part, although after I had tinned them, they felt pretty solid, and I was a bit worried about breaking them if I twisted them together.
The soldering station looks a good idea. Have to Google it when I get back from nightshift.

At a small price like this, there is little excuse not to get one at a store near you. Not the best of quality, but it gets the job done. It's what I use.

So as not to clutter the thread, I made a quick blog entry with some soldering hints: http://www.rcgroups.com/forums/showp...26&postcount=1

Hey, thanks for that. I haven't checked for almost two years. I was never near the one on 290, and now I find out I drive past one everyday from work? Guess where I'll be Monday on the way home?
