With or without Gyro's

Guys,
Before we had CP we flew FP, so jsut to let you know, if you increase your head speed and tail rotor response, you can fly without a gyro. All those who flew prior to 1990's could not afford a gyro, I was one them.......we just compensated our torque curve and servo response time..........for all those who only flew with a gyro, you will never know what the basics is.........like I said before, anyone can fly with a gyro, try without. Besides if you all are accomplished pilots, then what is the harm? Has anyone flew a fixed pitch without a gyro? Those guys are pilots.......comments? By the way, if you trun down your gyro to 20% like I do and a few others...its almost like flying without a gyro........after you feel confident, turn it down to 10% and before you know it......you will be at ZERO. Also just to let you all know and remind you....in forward flight above 10 KTS, you are barely using a gyro anyways, its in the hover when you have a crosswind that the gyro truly works, not buzzing the sky....otherwise why don't RC Planes use gyro's? Foof for thought...Happy Hovering!

Like many others here, I learned to fly helis long before gyros were invented.

BUT (and its a big one!)

Back then helis were DESIGNED to fly without a gyro! Basically this means that by modern standards they had very docile tails!

Before you try flying a modern machine without a gyro, bear in mind that it will have a MUCH more powerful tail rotor - it will be relying on the gyro to make it manageable.

You will need to cut the rates on the tail right down to fly without. I haven't tried it recently, but you are probably talking about 25% compared to normal. Better to start off with too little control (you can always land immediately if you haven't enough control) than have too much and suddenly find you have a tiger by the tail!!!

Best of luck!

put it this way, they wouldnt have invented gyros if it was easy to fly without. have you ever watched a vid of flying without gyros, your lucky if you can keep it in the air for a minute, no matter doing chaos's

The last time I flew without a gyro was in the 80's on a GMP Cricket. Yea you can do it and I do reccomend giving it a try just another heli challenge to overcome.

One mile of road will take you one mile. One mile of runway will take you anywhere in the world.

hows this,I'll send you a G90 gyro to use till yours gets back if you can hover a BLADE400 for 30 sec with controled landing,with no gyro.Video proof of course

Has anyone flew a fixed pitch without a gyro?

Around 1978 I played with a .35-power FP heli. It was grossly underpowered, could barely lift its weight plus the training gear, and at max power it would skid around a few inches high, occasionally touching the ground. It needed large amounts of tail rotor input to maintain a reasoably constant heading.

After that experience, I thought I'd give the industry a few decades to sort itself out, then I'd try again. And now that we do have gyros, I wouldn't want to fly without them again. Been there already, thanks.

IMO, "barely" is stretching it a little. Modern 3D helis with their fake, wireframe vertical & horizontal fins (for good 3D ability), have very little weathervane effect. And during hover, it is power variations, not necessarily crosswind, that make the gyro really useful.

Because they are fixed-wing, and their torque variation when compared to the aerodynamic forces that keep them put are vastly lower than that of a helicopter?

exactly,a plane will fly straight(once trimmed)till you tell it other wise,if you can get a 5 sec hands off hover on a heli,you are doing really well

man I have MAD respect for the guys that started this hobby,that must have been some time and skill to get those early heli up in the air

anybody that wants to see what its like to fly without a gyro,go get a used bladecp turn ther RATE gyro gain all the way down and do some collective punches,and let the fun begin

Thanks for the offer Fender. I should have a JR770 and a 3400G on it by the weekend. But rest assured that I'm going to look into this no gyro flying. NGF we'll call it. What better way to become a better pilot than flying with little or no input from a gyro. I think the idea of turning the gain down further and further until you are in complete mechanical control of your machine is the way to do it. To me this sounds like a worthy challenge. It would be interesting to see what the big names in our hobby could do with a heli with no gyro installed. I would imagine some tricks may be nearly impossible without a gyro. I'll wait until I'm a little more experienced pilot to start this challenge, but I have every intention of exploring this further.

Thanks for everyone's input!

Stick bangin' cuz my hands are shakin' !!

Great Comments, especially from the seasoned older pilots! Try it, its not for the faint of heart.........Happy Hovering all!

I "flew" my 300 sized King2 without a gyro for a whole pack once (BTW a whole pack is like 12min). I had training gear on and it was a little bit windy out but I thought what the hell, why not give it a try ... it's not going to hurt anything. Well it didn't hurt anything but I will say that it is damn near impossible on a small heli like that. I started out by trimming the tail until it kinda held but every little change the heli made translated into tail movement and it was just too fast for me. Now I learned on a crappy peizo gyro, so I can hold and counter the tail constantly but this was just too much. I bet I had 2-3 5sec hovers but they were all over the place. Maybe on a bigger heli the weight would help a little but I still think it is near impossible to fly well with out some help, be it a mechanical gyro or even some radio mixing.

I would think anything but basic circuits would be ALMOST impossible without a gyro.Definately give it a try though,because it will make your left thumb awesome,as I'm conviced my BLADECP helped my left thumb a ton,I can fly the tail pretty well now

for example a flip,when you go from postive to neg pitch the tail is going to want to swing out when you go 0 pitch then come back when you go neg and again when you come around,you'd have to compensate for that throughout the entire flip,not easy I would think

but guys have flown em without so it can be done,but out of curiosity,guys who were flying back then,what was the limit of a helis moves?

Try putting the gain to 0 on a sim first before flying a real chopper with no gyro. You will be fighting the machine the whole time.Imoo its a stupid idea and you should wait for your gyro or bite the bullet and purchase another one. Unless you dont mind spending money on rebuilding your chopper, then go for it.

Just put the TG on and keep it low! That way you can't hurt anything and it is a good exercise in respecting anything that resembles gyro

No really everyone should try this once so you can have a better understanding of what a gyro does and just how hard it has to work, not to mention just how freaking awesome today's gyros are in order to keep your tail "rock solid" no matter what you do to it.

Hey guys, what's a gyro???
Me I do not have one.

No, I'm joking...
But I already had 2-3 times that the gyro was inverted... Thats even more scarry than no gyro...

Maybe we should open a competition with only inverted gyros
