I Can do that without problems. View my other video I posted today. (the one carving in a tiny backyard space, where the camera person was less than 5 feet from the heli at times)
I refuse to defend myself against people who hold a grudge for no reason. You will find any word I say to pick me appart because it's what you do for fun. Have fun, thats all this is intended as anyways =)

Hey Casey,

Sorry if you felt I was being overly critical, but there are several holes in your stories that give the feel of urban myth, therefore reducing the chance of getting much respect from your peers for your achievements:

1) You're claiming to have not only spooled up a heli at 5k rpm, but actually flew it for over a minute. When you do something that contradicts all recorded history and fail to show proof (I saw no close-up on your tach to reveal numbers), it's unwise to expect applause.
2) You claim the camera man was less than 5 feet away, at times. I believe you're referring to what's been commonly known as a camera's "zoom feature."
3) You're claiming to be flying 3D, while at the same time the camera is out of focus. I'm not doubting you can fly inverted, but with all respect, your already wacky claims cast overall doubt on exactly what was done in your videos.

Here's what I'm guessing, based on your videos. First, you're holding the tach from the ground facing the sky, and the only thing you're going to get are a bunch of jumbled numbers that reveal nothing about true head speed. The only way I've ever gotten accurate readings is at half-stick (assuming you're at zero pitch), with the heli on grass, and with the tach around mid-blade shooting at the ground. When you get a reading that stays around the same for a few seconds without jumping, you're getting an accurate reading.

Second, you fried your motor because you used the wrong pinion. Every motor, ESC and battery combo require a certain pinion size to get optimal performance. Typically, 11-tooth pinions work fine with 3000+ KV motors on a 4S pack, while 13-tooth pinions work fine on a 3S pack.

Third and lastly, you've proven that you don't understand the safety risk in RC helis. At 65% throttle curve I reached slightly below 4k rpm; the frequency was so high that it sounded like it was about to break glass! I felt extremely unsafe being within 10 feet of it because if anything came loose, it would have ripped through me as if I were paper.

Other than that, I didn't get anything else from your videos or posts. Sorry.

Later,
Scott

1)
When you saw me reach my hand out with the tach and measure it in the video: the headspeed was at 2300rpm. that was not the video where I was at 5k. None of the videos were. One video was at 4k something on a dead battery a thread ago. Look in my profile to find that thread.
2)
I'm claiming the camera man was less than 5 feet away in the video I posted yesterday in another thread titled " for kicks, my old trex video" In which I am doing 3D in my backyard with a perfectly normal flying TREX CDE.

3)view the video in my backyard. How could you doubt I can fly inverted?
You people are crazy making tons of assumptions out of nowhere!
I don't need setup tips. I have flown helicopters for years, built them for a company who sold assembled ones online, and I know my helicopters.
I was trying this motor on 4 cells and found it not to work. I then proceeded to kill the motor on video, having fun, trying to finish it off (cause it was going to have to be replaced anyways)
If you'd like to pick appart any more of what I wrote, I will gladly help you figure out what I ment. I know what I'm doing, and I did it on purpose. I have 3 other TREX's that fly just fine. I can do perfectly good basic 3d manouvers and I can hover inverted WHILE piro'ing. I don't need you to bring me down. Sit down, shut up and watch me kill a motor on video. Who cares if you believe what I'm saying or not?! I know what I'm saying is truth. How is a metal tail going to implode or explode at 25,000rpm? IT"S ALUMINUM. Doesn't anyone think anymore? I didn't hit anything. You guys are exaggerating everything you say just by those few words "I can't believe your tail didn't implode". Everything I have said here is 100% truth, and I'll take it to the grave.

I may not have been in the RunRyder forums lately,
but I'm sorry to see it has become what it has. This used to be a great place to share information. I'ts a shame nobody has respect for anyone in a forum anymore. I would not come here to tell you lies all day or give false information. If you believe that is what I am doing, That is fine, and I will stop posting results. I Can only tell you what happens from what I Saw with my own eyes. I have frequently seen an increase in cocky additude among the helicopter flying groups online and at the field. You people are bringing the sport down and not helping add to the fun. I will be on my way flying my helicopters and will leave you to type in your forums while conjouring up drama. I'm in this to have fun, not to argue and bicker with people all day. I don't need to say any more here. Anyone who reads this can judge the instigators for themselves, and believe who they want.

Just FYI (in case you don't know/forgot): If you hold the tach too far in (or at any angle to the light source so the paddle's shadow hits the tach), it will pick up on the paddles and will read 2x the actual speed.

I was getting 43000 rpm on my Nelson Q-40 engine untill I put the tach on 2 blade! Common Willy give the guy a break,,,,,,Ignorance is the absence of facts.Stupid is lacking the intellectual capacity to comprehend the fact

who cares who,s right or wrong, just show us a video of a trex doing 5 k at the head with the tail still attached.
Buy me another align 3500kv And I'll be glad to smoke it for you on video with TWO tachometers to verify it. Might want to send a battery for me to smoke along with it =D
Also, it was on two blade.
Pointing the tach up in the air gives it more light to get a better reading on. IF you are scared to be that close to your Trex, You shouldn't be flying it because you need to measure the head.

Casy, I smoked my old 3550kv align on 4s holding the motor in my hand using a spare electron6 and the 35amp align esc. The esc is now in a MicroJett thats fast as superman using an E-Flight six series 2700kv and a 5x5 prop @ 23,500 on the tach.Ignorance is the absence of facts.Stupid is lacking the intellectual capacity to comprehend the fact

You know what I mean..
Buy the motor, and I'll show you 5k on the head. And there is no way I was measuring the paddles. I was way out at the tip. Keep finding things to point out...
Lets do it. I'll take the time out of my day to pull out the mega motor I just put in the thing and prove it, if you are in such disbeliefe. the motor is what.. $50? you have money to buy Aplus400's.. so I'll split it with you and well get it on video.

Just to throw another point in, my Trex tail shot past my head at the speed of light about 3 hours ago. Let's see... I believe this is the 4th time in 2 months. This time the blades were full carbon fiber, unlike those crappy rounded "carbon" blades that are brittle, which sell for around $5 US, and blow apart when the moon is full.

Head speed was "only" 3,400. The fact is, the Align tail will not reliably fly much over 3,000 rpm without risk of the tail grips flying off the hub. This is because the bearings move in the grip, only a small portion of the screw goes into the hub, and the hub rarely seats perfectly perpendicular to the shaft, at least in my experience. Inside word has it, though, that a new Align tail rotor is sitting in crates somewhere waiting to make their way to the States, and they have a redesigned rotor that uses thrust bearings!

BTW, the Align ESC sucks if you're using a 4S pack. The Jazz 40-6-18 is the only one that's truly designed to meet that extra voltage, since it calibrates itself to the motor every time during spool-up.

The mega is on 3 since I converted over to 3 cells from 4. None of the above videos were on 4 cells, nor did I ever claim they were. The first video in the original thread was on four cells and that was after I flew for several minutes on a dead battery. I have flown this mega fine, and it is the motor from the backyard video, and still healthy as ever.
I also switched over to my CC35. The thing is flying fine now, and has had two flights this morning already. Tail is holding, thorttle at 90% and cyclic servos are great. I even slapped the carbon boom on in an attempt to lighten the tail some for better balance.

I'll be damned if I'm gonna pay for the whole thing up front and get nailed when I come looking for my $100. this is going nowhere.
Here is a picture for you to pick appart too

Flew the backyard video just fine =P
and when I bought it, the mega was brand new on the market, $107USD
It was already done before you started yapping and telling me what to do. I got one of the first damn Trex's from Fung and posted on here before anyone even knew it was out. I 've flown it in the living room, garage, backyardm frontyard, indoor gyms and anywhere you can think of. I was one of the first playing with Trex motors, and even making my own. You talk to me with no respect like I know nothing. Everything is 90* in the swash/servo horns besides the angled links. You can't make the geometry right without hitting the main gear or restricting the pitch. Are you blind man? Do you realise you can get more pitch this way without hitting the main gear? (or even worrying about it!) Talk about Mr. perfect! I'd hate to be your girlfriend!

One other point: if you have the money and want to fly 4S, the most efficient motor/esc combo is the Neu 1107/2.5Y with the Jazz 40-6-18.

The Medusa I'm running is way too hot for 4S, which is why I have to run throttle at only 47% max. As others have said, around 80% throttle is optimal to achieve HS in the low 3,000's if you want fast punch-outs or fly hardcore 3D. For just normal flying with decent power and some simple 3D circuits, rolls and flips, 3,000 rpm is perfectly adequate. I like fast punch-outs, though, so I push for the mid 3's.

Willy,
I bet you don't even have a TREX SE. I bet you've never had the 430L motor either. Sounds like you have the whatevermabobber with a whodat frame and aplus4000 and all this other stuff, but you hate your TREX because it took you so long to set up and the quality is this and that and you probably can't fly it all that well either. If you don't like Trex's, then you are here just to bag on them. How do you find this amusing? You don't have the experience with my particular parts to even be running me into the ground! My Trex is most definatley different than your trex in many ways. You are like that annoying guy at the field who always talks to me while I'm flying, ruining my concentration. There is undoubtedly lessons you will learn from this as well, like being an @ss wont get you anywhere but where you are at. Atleast Funkykeys is trying to offer help, instead of just being flat out, out of line. He spoke his point, I spoke mine, and now he offers help. That definatley hightens my respect level for him alot. It is hard for me to say I respect you very much with your wisecracking, unforgiving and childish additude. But I took the time to fight it out with you now. Hope you are satisfied.. and if not, keep em coming.

Lol this is great! Take it to him casey! I don't see the constructiveness in running a rex at above 4000 headspeed, but it sure could be fun, and worth a laugh. And as you said the motor was already toast so why not blow it up completely? As I have said before go 4s/neu 1107/2y. People seem to get all spun up if you do something that isn't the "right way to do it." Iv'e never heard you arguing that it was the right way to do it, I just see it as you having some fun. But WHY WOULD YOU DO THAT? This is a hobby your not supposed to do that! If you got the balls to spin a heli up that high, be my guest! From the sound of that video of over 4k on a dead battery, that is far more headspeed than I would fly or get near, and the tail seemed just fine. Your supposed to criticize people and complain about the quality of parts without end, and keep on buying them! Then when someone offers a counter point, you are supposed to ignore it and say some more childish things mixed in with some gay jokes. I bet you could never guess who I am talking about! I'll give you a hint: He "upgraded" a T-rex tail to that of a blade cp, and his flying abilities are among the szabo's.Timing is everything

I just love this friendly banter and I know it takes all types, but you just have to wonder about some eH Willy.
Even if hes not worried about his own safty what about others. As far as the 5K is concerned, I believe it when I see it, TREX tails are not that strong so.........................
I would suggest that he documents all the parts used in the heli to obtain the ability to stay together at high speed so everybody else can make thiers bullet proof at 3k. That would make for a lot of happy campers.

Caseyjholmes. By the way I have no problems with you haveing fun any way you please as long as others are not at risk and flying in a public place doing what your doing is not safe. So please if not for your own safty, do it somewhere it cannot harm others.
ENJOY your flying.

5000rpm???
i'm not a whiz at math, but here goes...
13t pinion puts main gear(150t) ratio @ 11.54:1
11.54 x 5000rpm = 57700 motor rpm
57700 / 3550 (kv of motor) = 16.25 volts
soooo.....
if he was supplying 16.25 volts to the motor, with none of the motor's output being wasted as heat, absolutly zero friction between any components, and no drag from the blades(must be a new design from that company he used to work for), then it is very possible. This would mean that Willy is wrong.......nah! this is more entertaining than lots of other fairy tales.

Willy...

I'm having fun reading your goofy replies, for what it's worth. Actually, I think most would agree you'd get the RunRyder Instigator Award if there were such a thing.

However, what the heck were you thinking putting a direct drive motor on a Trex tail??? LOL That's like putting the wheels from a Pinto onto a Corvette! I guess everybody likes to experiment with different things, eh? hehe

Later,
Scott

well, i'm gonna go down and work on my new trex mod for a while. It's a new rotor-less design that has no moving parts, and derives its energy from a hydroelectric generator. Maybe i'll post a video when it's doneIf at first you don't succeed, lower your standards.
