I guess I should ask if you guys think they'll come up with one of their own design, or they'll stick with the clone?

I have an etra v911 board I was thinking of putting it into my sp329 for more servo travel but I think the motors would blow out the board. does any one have a thought on that.

boom and tail motor

This forum is a bit different and I didn't realize I should have been posting here as opposed to making a thread for my problems.

http://www.rcgroups.com/forums/showt...3#post22585325

I replaced the boom and the tail motor as well as the landing gear. Had everything re-soldered but the wires for the tail motor were on the outside of the mount for the tail motor. I wound up breaking the wires trying to get the motor in the housing with the motor later that night but they were already damaged from the first attempt to install.

I have the thing apart again and have more parts ordered for the re-fix. Do you guys not put the wires inside like it does come from the factory? Should I just run the wires on the outside and cover them with electrical tape to protect them? The replacement might not the the exact same either?

Also want to share how I took the boom, or what was left of it out of the main body. I used a 5/64 drill bit and drilled two holes from the sides, then from there it was cake to pull the old parts out. Even used the drill bit to drill out from the back where the boom enters the body to clean that all up.

If you mean SP328, then that is too much load. 328mm rotor diameter compared to V911 190mm rotor diameter. Doesn't the rotor load increase with the square of the diameter. Maybe fourth power since area is squared and the blade speed increases at the ends, squaring again.

My SP328 is a nice size and rather tame compared to the V911.

I haven't tried either. Doesn't the xtreme cf fb reduce strikes? I thought MassiveOverkill said that it did in his blog (or was it Erdnuckle2?)
Absolutely. I have never had a strike with the xtreme cf fb.

which is not a correct premise from the question you were asked, which was 'is the Helios fb stiffer'. From that premise, you could not say "The flybar doesn't bend into the helicopter." because everyone knows the flybar bends into the heli and if you make it stiffer or shorter it does not. I understand you are explaining how it flies, but you were asked if it was stiffer, not how it flies. That's all.

My very first Yellow V911 flight had about 30 flybar strikes and punched a hole in the canopy. The next flight only had a few strikes. Now I get only the occasional Yellow V911 flybar strike. I did not change the Yellow V911, I changed the way I fly it.

Change the flybar and you change the way the helicopter flies.

Change the way you fly the helicopter and there is no need to change the flybar. Flybar strikes are telling you that you are over-controlling the helicopter.
Like RoboHeli said, some of us want to do more, which is impossible with a floppy fb. If you don't, that's great, have fun the way you want to have fun. That's what it's all about!

If you stiffen the flybar, you increase the negative feedback and you can't force the canopy into the flybar.
While you may be saying, "hey I can use more control stick with the stiffer flybar and not have a canopy strike", I contend that it is because the stiffer flybar decreases the control authority that you can apply.

The wet noodle will teach you to be a smoother, better pilot.

You won't be doing things that require high negative feedback - i.e. won't be relying on the stabilizing flybar to save you from yourself.

As you get better, remove the weights...
Sounds good, but not reality. If it were, I wouldn't be doing circles around others with a wet noodle The wet noodle gives negative feedback for me. Is that glass half empty or half full? It's smoother, which I really prefer, but it's smoother because it's slower because it's flexible. Good for beginners, though, and good for anyone that prefers that style of flying.

When a tail motor dies, I cut the wires at the tail motor, replace the tail motor, scrape the enamel off the wires. and solder.

When a tail boom breaks, I wrap it with paper towel and superglue the whole mess.

If you put the tail motor wires on the outside of the tail boom, nail polish is good to hold it and protect the wires.

A product called Un-Cure is a debonder that turns the cyanoacrylate (CA) glue into a gel, but you have to keep poking the glued part, wiping, adding more Un-Cure.

I pried all my weights out and glued them in.
Might not be all she would cut off

Using the braided fishing line and CA glue on mine eliminated the strikes 100%. I can get nuts with the heli all I want and have not had a flybar strike since. Thinking I might do another CA glue coat though to be sure. It still has a little flex, but that is ok cause it wont snap on a crash, but not enough flex to have strikes at all. I am doing my other bnf I got as well before I fly it very much.

The Extreme CF FB need a small piece of CF or similar glues onto the top above the attachment point though cause people have said that is where they break.

+1 on the Walkera Genuis CP clone! (or Exceed X100, same thing) with the 3 axis and 6 axis gyro. If they cloned that feature as well, I would buy one right this second, no hesitation (after all I been debating buying one of those)!

If you really want to have fun, make a flybar from string tied to the center core of a broken flybar, with weights tied to the ends of the string. Then fly it without flybar strikes. The ultimate floppy flybar wet noodle.

Just thinking....

One length of fishing line wrapped around what remains of a broken flybar.. A way to attach the end of the fishing line to the main blades so that it goes free when RPM increases. A way to untangle the mess after crashing into bushes.

The angle would decrease from 45 degrees so flybar influence will be further behind the swashplate.

This.

Also, your patience hasn't been tested until you place an order at the beginning of the Chinese New Year!

I bought my V911 BNF, V929 Tx, and spare batteries from BangGood on Sunday, when all were listed as "in stock". Since Monday morning my order status still says "backorder". All items I ordered still show as "in stock" on the site.

Is this just a delay because of the Chinese New Year, or is something really out of stock? I'm not angry, just bummed. Sorry if I sound like a whiner, but I was hoping to take it on Vacation in a month.

What are you going to do if the BNF is broken?
