HelicopterOutrage 50-90-Nitro › Velocity Head Ripped itself apart in flight :(

Sigh, I really don't want to argue about this. Am I basing this on actual tests done on models to see what loads they fail under? No. All I'm saying is, I've seen "beefier" heads. The evidence is quite obvious. Take the flybar cage on the velocity and put next to a Century raven flybar cage or even a trex 600 cage. Even the screws that hold the cage together are bigger. Further the amount of material that is around where the screws mount is much more substantial as well. This is from VISUAL inspection. Lay the parts out from the velocity head next to equivalent parts of many (not all) helicopters, and you will SEE that the parts on the velocity are not as BEEFY or as BIG as others. Please do not get defensive over this. This is JUST MY OPINION of it. I am NOT making any claim that it isn't strong enough to withstand the rigors of flying cause I'm sure it can since it is quite popular. I just prefer my head to have a little more "girth". Maybe I've just gotten used to "fat" heads Seriously, it's just my opinion. For the sake of the Velocity, I hope this event was in fact builder error (sorry dude), but on the flipside of that same coin, I trust flyingman in his building ability and expertise. It COULD be builder error, OR it could be that the part really did just fail. It's hard to say either way. Again, this is just MY OPINION and it's not that big of a deal.

PS and just to be fair and show that I am not singling out the Velocity. I feel like the Fury 55 flybar cage is not substantial either (despite the rest of the head looking quite beefy). Compared to other MA helis, the new flybar cage is DEFINITELY not as beefy. Will it work? I know it will, it's MA, but I still don't like it and I still don't think it's as beefy as I'd like it.

Sorry to hear about your crash dude What i would highly recommend is that in the future when you check for binding you not only hold the sticks in the corner and listen for servos you actually spin the head. While holding the sticks and spinning the head you can often find binding that a static test wouldnt find.

I have to agree with Quantum, after seeing some century stuff upclose they are built like a tank ......... they also fly accordingly.

Kaz,
Obviously the poster was referring to pot metal " a cheap low melting point alloy" and in defense of what Quantum was suggesting " his words were "I always thought" meaning his interpretation. The fact is when viewing this thread and looking at the picture of the broken cage the first thought that came to my mind was Pot Metal - I'm not the only one - I have had three people PM me asking me about my prior experience having owned this helicopter and I tell all of them that "in my opinion" most all of the metal used in the Velocity is of sub standard quality. I don't need to prove it to anybody -Compared to other helicopters I have owned and built it is simply low grade - again in my opinion. In many threads you post in you seem to demand that someone must provide proof of their statements or opinions. These are OPINIONS - nothing more, nothing less.

Problems ? -- Mine are flown in fresh daily

wow and i was just kidding. Even the lower cost helis are using aluminum 6061 or better esp on the head parts

He used the words, "not enough beef", which would imply a "lack" of something that "needs" to be there. There is no evidence that this is true. And I asked twice for him to tell me which helis he was referring to, which he eventually did. I would say the amount of hours that have been put on these seem to prove that the head is sufficiently strong, regardless of one's opinion or feelings. I don't need anyone to prove anything to me, but if you're going to state an opinion I don't think it's outrageous to ask him to defend it. I have had discourse with many that have won me over to there opinion by defending there's with good supporting information. I am not claiming any superior "opinion". Of course I knew he meant pot metal, can't I make a joke.

This is partly why I let my Velo go, the attitude of some Velo owners/ team members jumping to its every defence seemingly in denial at every fault others experience.

Yes so far things have been addressed but only after parts have been failing. Many of these probs have been avoidable but why ignore what others are experiencing just because its not happened to them.

IMHO the Flybar cage is underconstructed, + mainshaft is insufficently inserted into the headblock..+ other quite a few other easily avoidable issues. Yes it all saves weight but at a cost in the longer term reliability.

This is true, I did say that and that IS what I meant, but I think you're failing to see my main point. There is not enough there for ME! I made no other claim beyond that...

i fine with your guys opinion

but its good anuff for me, i will beat on this thing right in my face and I 100 percent believe in this heli even in my heart, but i also know nothings perfect but where getting close.

i have crash and made a lot of mistakes... 95 percent of my crashes was due to builder mastakes, and that because im not perfect.

if that heli was made of pot metal, when u hit the ground it would destroy the head everytime you went in. IMO

and those outher helis need a bigger cage, there f ing pigs and way slow lol

i have crashed the v 50n 5 times, no broken head parts, and no broken frames... YET, got to be running out of luck soon..lol.

sorry to hear about that crash.

happy flying guys.

My guess is binding as well it is easily over looked when setting it up.
I beat the ****out of my Velocity no metal issue here this machine is bad ass

I think alot of ppl's problems are related to them not checking their pitch ranges. Many ppl will attempt to setup an Outrage machine like an align... aka max pitch values before it binds in a static test. If you have built your machine with the proper pitch ranges your values will typically be below 50% in the swash menu. If you leave the default 60% in the swash menu the head will bind dangerously.

Yep. I think that was my problem... this will be the first time i have every messed up a building and setting up a heli in 7years, and about 25 helis Have to get back on my game i guess .I also haven't flown it as hard as I did on Sunday. I was really putting a hurtin on it. I looked at my swash values... they are 50, 50, -50. if i remember correctly i had like 14deg pos, and neg, on the pitch, (maybe 13 but i can't remember).

All this talk made me go look at my setup, My Velo is built on all advanced settings per the manual I am currently using
54% ail
57% ele
-56% pit

I looked at my head block and I have no signs of contact with the links at all. I know when I set it up that it will touch if I go full collective and cyclic at the same time but who really does that when they fly? I only measure pitch when I intially setup a new heli for the first time. I always set 12 degrees to start with. I then crank the cyclic as high as I can with out getting binding in the normal range of 3D flight I just use this as a starting point and fine tune it by flying. All my helis bind in the corners and also bind when giving full collective and full cyclic. I never bang the sticks around hard enough to get into those no-no zones anyways. Works for me and gets the heli to "pop" and "stop" how I like it to.

7075-T651 American alloy
6061-T651 American alloy
I have been working with all types of alloy since the late 80s. It dose not matter how good the alloy is that you are using if it is in cast form it is not going to hold up to vibrations as well as the same alloy machined from solid stock. The cast parts are way cheaper to make but are in NO WAY as good in quality as the machined parts.

Man this heli is fassssst !!!!!!!!!

I believe his point is that they use MACHINED alloy parts, machined from 7075 T6 and 6061 T6 alloys, NOT cast aluminum POT metal parts like some of the Align parts...

Correct!

In fact it does not matter what material you use if you have collisions in the head. Fatigue will eventually get it! nothing was meant to be beaten 2000 times per minute..........
