Humm, just wondering why you didn't go brushless for the tail as well. It is soooo much better and lasts forever.

That is my next step, and now with the separate radio gear I don't even need a brused>brushless converter. However, at the time, I didn't have the $$ for a 12mm brushless motor and ESC...

thanks for your advice i did what u said i pulled the head gear appart and spun it up and the shaft looked fine. i replaced the flybar controll tray, flybar, rotation holder ass and placed on new blades.i now get some vibration before lift off. i have also notice that while it sit on the ground that it makes some quiet noises like the servos are actuating but very slightley any ideas

Morning Gilros82 and Great_Life:
Most of us buy blades and other parts from US Hobby Supply. Michael the owner has great prices and ships quickly, usually the same day. For now his blades are on sale at buy one set get one set FREE and the price is $3.99. (Link Below) I have used these blades as stock replacements since I started flying, and have had NO problems with them. They fit perfectly and fly great. Also do not forget that if a part is not listed on the Falcon 40 parts page to look on Michaels Wlakera4 parts page as ALL the Walkera4 Falcon 40 parts are interchangable.

http://www.ushobbysupply.com/product_info.php?cPath=31_35&products_id=36&osCsid=6feeafa9cff8721d58c5fd1a186cf3f7

Have A Great Day

Morning all! Trust you are all doing well.

Had an intresting experiment last night. I was doing some bench testing and tweaking and I thought I'd give the stock pack a try with my new setup which included CPP main w/11t pinion and CPP tail motor. I also run superskids, stock everything else. The only other added weight there is 2 fuses from motors to 4-1 which is negligable. The Falcon would not get itself out of ground effect with the stock pack. Popped my 2s 900 15C lipo back in and there she goes flying great. I think that the 11t pinion increases the speed of the head but just dosen't have the toque to lift the extra weight of the stock pack. I may have to try out a 10t as a happy medium between the stock 9t and my 11t. HMMMM

When I fly my lipos it gets good lift and due to extra headspeed provided is quite stable in hover but the running times are down from 11min(stock motor 9t) to 9:30(CPP motor 11t) It's hard to tell if this is the function of the pinion or just the charcteristics of the new motor. I should have put the 11t on the stock motor to see the effect before switching. At any rate I can accept the decreased flight times in exchange for how well it's flying right now. Besides I have several lipos and a good charging station so keeping it in ther air isn't a real problem. I pretty much only have time for about 2-3 packs a day anyway due to having a newborn boy and a 2 1/2 yr old girl at home.

So if anyone is intrested in 2 stock Falcon packs I would be willing to trade for some spare head parts or aftermarket stiff blades. PM me if you're intrested.

Have a great day all!

just a quick question , if i take of the main blades and spin it up to full rpm and it doesent vibrate does that mean that i have a dodgy set of blades

From my experience blade tightness is crucial to a vibration free flight. My Falcon likes the stock blades to be quite tight. As a matter of fact they need to be so tight that they don't really spin out so I have to adjust them to level by had before flights. They will still fold in the event of a blade strike though but they are really on there. I have tried every tightness from floppy loose to so tight they don't fold at all and this is the best for me. I think that it's unique to everyones bird depending on the setup. Before I replaced the baldes I would try some different tightnesses on the blades. If mine aren't perfect it will vibrate but once I get them dialed in it runs nice and smooth.

Something else is paddle pitch. You wouldn't really notice vibration without the main blades if the paddle pitch was off because there just isn't the gyrational force there to get the vibration. Once you put the blades on though the force on the paddles increases alot and at that point the shimmy will become prevalant. Be sure that they are both exactly level when they are 90 degrees to the tail.

Let us know how it comes out!

You may just need to balance them. The easiest way (for me at least) is to take the blade/rotor head assembly and balance it between 2 beer cans (rest the ball links on the lips of the cans) and you might see one blade dip lower than the other. If so, take a small piece of pinstripe tape (the amount will vary depending on how much the blades are out of balance) and apply it to the end of the rotor, about 0.5 to 1" from the tip. Check the balance again. Keep varying the amount of tape or where it is applied to get the blades so they will balance level. Reinstall them and try a flight.

There are a few more in-detail methods of blade balancing discussed earlier I believe

Also, be sure the amount of pitch (angle) is the same for both blades.

I finally got some video up on youtube. Was some just some hover training so it's not all that exciting. Was a bit squirlly at the start and almost ditched it near the 1 min mark but made a "by a hair" recovery. Also did some directional goofing off near the end. Enjoy!

I've done a similar experiment and came to a different conclusion...

I've gone from floppy to tight and didn't notice much of a different (vibration wise). With the blades tight, it's easier to spin up (and it doesn't go through a violent shudder as the blades are centering), and there's a bit less vibration, but not really enough to care.

I would agree with you about the vibration not being huge in blade tightness but I'm anel and don't like to have any. I think that the paddle pitch is more of a factor but blades do contribute. If you had both problems going on at the same time it would certainly make a difference. So how tight do you run your blades?

Thought I'd post this. Some of you may have seen this or may be using these parts. i'm curious about the compatability with the Falcon. They look like they'd work but no way to tell without buying and they are a bit pricey. I don't see any set screw holes in the control ring and I'd like to see the bottom of the rotor head to see if it'll fit the falcon's rotor core. I don't really see any problems with the swash plate. Looks like there are control arms in the correct locations.
