Thanks Integrity!

Thanks for the blade list, on order, should be back in the air mid week...I will be standing behind a sheet of 3/4" plywood with two holes cut in it for my eyes until it clears the ground and is in a stable hover.
Just kidding.

What is that thing on your TX? A fumble guard so you don't accidentally hit your power switch?

Nice flying man! Your skies are looking as bleak as mine! Damn weather sucks! But it's better than the 110(f) weather were getting lately. August is the worst! I'm glad your having such luck! It looks like you about hit that tree once there but you were probably miles away. Perspective can be fun sometimes


SO....NOW IT'S SHOW AND TELL TIME KIDS!
Here is a little recipe for you all not to follow! Before throwing away most of last month's and this months garbage i picked out the relevant parts to illustrate just how lucky I've been with this helicopter. You can clearly see the 120 and 200 size main gears and how many of those i've gone though. Most of the 120 gears are for the D05 which are tiny teeth that strip easily. So in contrast to the v450, i have to say... a picture says a thousand words. Keep in mind all the v450 crashes were failures, while all the other helicopter's crashes were "oops" moments for the most part.


Since i straighten all my main shafts myself and often repair the landing skids too, depending on damage. It seems VERY lucky to me that this is really all the main parts i've had to replace.. Oh yeah, 2 tail booms and 1 rotor head too. But otherwise, i never had to change the align FS. Interesting side note, the FS in the new WK rotor head was shaped just like the align FS, previous ones were not a different diameter on the tips, like the Align FS. They were the same size all the way down the FS, but not the new one. It had no Align branding on it either.

So, MAYBE!! i have my issues sorted? Or maybe the heli just felt like flying good today! I flew another 5 packs today with no issues or failures. The pitch control felt good but the head speed still feels like it's slow. I'll be getting a digital tachometer soon, but it's been a real issue finding one that works on a 5 blade rotor. I think i found one that uses a laser that will work on any rotational part.

So here is the 4th and last video i shot of the v450 today. I actually flew 5 packs but because of the rain i kept having to dodge. I think i forgot to record one or something.

Rotor head changes

@IntegrityHndywrk-

This is a little OT, but it's related to the V400d02 head which is the same as the V450 if I'm not mistaken?

I have 3 V400d02 rotor heads here, and have also noticed a difference between the feathering shafts in one of them.

2 of them have stepped ends on the feathering shafts, and one is just a straight shaft if that makes sense?

From what you say above, I gather the stepped feathering shafts are the first released ones, and the straight shaft is the revised version?

Do you know if an alternative/stronger replacement feathering shaft has been found for either of these heads?

I would be particularly interested in finding a "straight shaft" replacement, as I believe there is an Align part for the stepped version.

Thanks.

Integriy,
Do you run a shear pin for the main gear in your D05?
I have a roll of copper wire that I cut and use as a shear pin on my M120 with the fine tooth main gear and it makes all the dirfferance in the world for preventing damage. It won't protect it completely in a really nasty crash but you will still be able to fly it. Minor crashes that shear the pin don't do any damage at all. The shear pin also saves the main shaft from getting bent and blades from being scrapped.

Yes, your correct. Same rotor head. But I'm not sure which FS from walkera is the newer version. Being that i don't know how long my parts sat around at the vendor before i bought them. But the stepped end FS seems stronger and has taken at least 2 crashes without any bend. The "non stepped" FS seemed to bend easier. I don't know if there is a metal composition difference or if the steps on the ends actually increase center durability by shortening the length of the main section. Physical properties of metal are strengthened when the length is shorter. As for a replacement, i personally use the Align 450 pro spindle shafts. They are stepped on the ends, but my previous one went though at least 6 crashes and is still straight.

Yes, i use a paperclip for a sheer pin. They work okay copper wire is probably better. I was thinking about getting some 1mm aluminum stock or wire. I belive the stock pin is 1mm so the conversion to AWG should be about 19 AWG, right? what size is your wire? Or are you just stripping and using a random piece of solid conductor you found? Anyway, the problem i was having was the sheer pin not bending or anything and the center hub of the main gear would explode! because it is drilled out to fit the bigger D02S shaft.



NOW FOR SOME MORE SHOW AND TELL!
As some of you may know... My poor experience with the v450 has left me pulling my hair out and searching for a heli with design characteristics that i am happy with. I know the Goblin has been well designed and has been the main heli I've been looking at for a bigger size for a long time now. If anything just for the cool body design and solid tail boom. But it seems that there has been an issue with the heli that is quite nasty if you don't set it up properly. Take a look at this video explaining the problem, then the following video with the setup problem in action... Its quite disturbing to me, being i don't fly a 700. But if this happened right in front of my face i would be scared to fly the damn thing!

It appears no matter how much or how "quality" a heli is. These kinds of things can always happen and seems to be much more prone to the bigger helicopters.

V450D01 with FPV and water dropping hardware

Here is my V450D01 with a sony camera, 900mhz transmitter with a custom made long-line hook controlled by my AUX channel. It all works & I think the new faces look way better than the stock Walkera faces! We have had all sorts of stuff attached to this bird and we are amazed what it will carry!

Yup, I have several fibreglass faces for my 450. No drilling!! I have pictures on here somewhere. Way tougher, easier to put on, $12 each, many colors and look way better!http://www.hobbyking.com/hobbyking/s...idCategory=445

You just move the rear canopy mounting studs forward to the two forward frame screws and it lines up perfectly! http://www.xheli.com/canopy450.html I was wrong.... only $8 each! The Walkera stock 450D01 canopy is too weak and its dog ugly!

Wow! Sounds like a great idea, so what size copper wire do you use to make a shear pin out of?

I just knew these forums would put out some fantastic information/tips!

Thanks for the canopy mod tips. I'll definitely have to try that.

Fantastic video! You know in the years that I started flying helis (1997), I have never seen a boom strike while doing 3D. Only when someone had run out of fuel (with a bad AR) or the engine flamed out. We were only running at maximum 2250 R.P.M. head speed on 30-90 size helicopters with 4 foot-6 foot rotor spans.

Your video impressed me, even though the rotor speed is higher on what we are running in rotor span size (more centrifugal force holds the blades straighter), it seems that the real big heli electrics companies are not being careful about maximum flex in the blade with their super rapid control stick actuation's, and the dimensions on their boom mounts.

I had a real helicopter pilot down at my RC Club ask me what speed we ran on the rotor, he was really astounded! he said real helicopter only run around 900 for a head speed. Now I know why they get so main boom strikes when they have to do a AR.

Doesn't tell me the AWG of the copper wire, yes! I saw someone calculate 19 AWG, but they don't make 19 AWG in the U.S.of A.

If that was supposed to be a smart-alec remark in your response I'll say to you Thank-You. & forever not listen to you again.

But if that was some sort of short-cut code that I really didn't understand, I forgive you & please let me know what it means?

I have a Devo 6 and am thinking of getting a 2702V-D for my kit 450 heli. Any reason this isn't a good idea? I read thru some of this thread and didn't come across anything that said it was a weak point of the V450 unless I missed it.

And while I am here, what is the difference between the 2618V-D on my V200D03 and the 2702V-D. Would the 2618 work in the 450? Pardon my newb questions .

I should mention that I can't do hardcore 3D, just sport flying with flips and rolls and short inverted.

Thanks,
Moto
