I have a hibro shuddle Z and i would like to know if I can use a smaller or larger size blade for the main rotor. I think it takes a 550mm with a 12mm grip/root.
I think some one told me that the shorter blace would make it go faster, but the longer blade would give it better stabillity.
tks

The limit on max blade length is hitting the tail rotor. Longer blades offer lighter disc loading (generally a good thing), but require more power to push them. If your power system is marginal, then longer blades is probably not a good idea.

Shorter blades usually offer nothing positive to the heli's flight performance. Higher disc loaded helis can be desirable in windy conditions, but as a general rule, aren't desirable.

The blade length for any heli is designed in combination with the design weight of the heli and the power system intended, and most manufacturers arrive at the blade length via flight testing etc. So deviating too much from the designed length usually heads you in the wrong direction.

@ dahld, If a kit comes with blades are the blades Peek performance for that kit or a general starting point?
Thanks.

Stick with stock

This says it all. Stick with stock 550s on the Shuttle. OS .32 most likly for power. Any larger would be pushing it. If you can find 570s and they don't interfere then give them a try. A tad more stable. A .50 swings 600s-640s. A newer OS.37 could probably swing the 570s easily.

Blade size
Tks Guys for all the info. ** Another stupid question.**on the receiver [ futaba 7ch,fp-r127df] what is the B stand for ,it looks like it goes to the switch that is mounted on the side of the heli body. I also have another sw for the gyro. But the one that is mounted on the heli body dose nothing it seems. I can turn it off and move the transmitter contorls and the servo still move.I don't have any other ele. things on the heli.
I traded this awhile ago for something i had.I did have it hovering last yr and it worked good, ha ha After i had to learn a little bit about setting up the transmitter and adjusting some of the Rods on the heli itself.
since having the blade 400 ele, i learned more of setting them up and balancing blades and stuff like that.
gave the 400 to my son.
Now i'll have to learn more on this. I also had the flight sim. son also has that now. $200.00 down the drain. LOL.

Guessing, it could have been a switch for an external battery powering the RX.

Pictures maybe?

Two switches and an old Shuttle. Any chance it has a very old mechanical spinning-mass rate gyro installed somewhere? That would explain the extra switch.

dkshema the one switch that is just kind of like on the 2 wires controls the gyro.The other sw is mounted to the left side facing the heli and it plugs into the receiver in i'll say the number 0 spot , then the rest of the plugs 1234567. Also i noticed that when i push the Left stick forward on the transmmitter BOTH servo's on the top move at the same time. Ill try to take a pic, and see if I could post it.Someone mentioned pic.
Now you got me going. Im going to go look at that sw. again. I tried to look it up on the net, but no luck. Futaba 7ch. [ FP0R127DF

Well i went and looked at the switch that i mounted on the fram, well one set of 2 wires goes into the side of the sw, they come from the reciver B not any of the 1234567 . and their is TWO sets of 2 wires coming out of the back,and these have a male and female plug. Right now they are pluged together, and seam to control nothing.
Its a 5 servo setup 3 on top and 2 on the side.
Question. on the transmitter the Left stick controls what?I know its for the gas, but i also thought it was to control the rudder or Left or Right on the tail rotor. The tail rotor is hooked up to the Right control stick.

First - receiver. 7 channels labeled 1 through 7.

"B" is for the Battery to plug in.

Switch harness has three plugs on it.

Two come out one end of the switch (one with a male plug, one with a female socket), one comes out of the other end of the switch and has a male plug on it.

The one coming out all by itself with a male plug goes to the "B" port on the receiver.

That leaves you with two remaining plugs, one male, one female. The male plug is the charging plug, your receiver battery charger would plug on here.

The remaining female socket would have the battery plugged into it.

There are a many bigger problems that you have, however. One is that the Shuttle Z is pretty much a horrible choice for beginning pilot today as parts are scarce as hen's teeth (among other reasons). I'm guessing the motor is as old as the heli and most likely is an OS 28. The radio is quite old, I'd really be concerned about the batteries all around.

Some of your remaining questions indicate that you aren't too familiar with radio control stuff. You may want to find someone local who can assist you.

Left stick on the transmitter should control throttle (and collective pitch) and the rudder. The right stick would control fore/aft cyclic (elevator) and left/right cyclic (aileron). What transmitter came with the heli, by the way?

I assume both axes of the right stick return to neutral by themselves. This then assumes the throttle stick is on the left side and doesn't return to neutral, and its left/right axis (rudder) does. I'm assuming you have a Mode 2 transmitter.

Hi Dave. you are right. When i traded for the shuddle he also gave me the booklets, and I did find the SWITCH with the 3 sets of wires and just like you said they showed the hook up. I now have to set up the correct servos for the right and left sticks.But even with the way it was set up i did have it hovering and flew it a little.
Tks for all the info / help.
Its nice to talk to all the nice people on this forum.

I checked the wiring,from what the other person did, and it looks like he had it wired a little wrong. So the Switch on the side of the frame with the 3 sets of wires is for on and off Power to the receiver and also charging.
So now everything is moving correctly and the rear rotor is controlled by the Left stick. My QUESTION is now ,when i push the the left stick forward both servos move, the gas and the main rotor. is that how it should work? It also has a GYRO CONTROL amp. But thats controlling the rear rotor.
Could it be gas and lift at the same time?
tks again.

Helicopter radios are helicopter radios because they allow you to slave the throttle and collective pitch servos together, to the same stick.

When you add throttle, you also add collective pitch. When you reduce throttle, you reduce collective pitch.

The rudder stick still controls the tail rotor; the gyro is installed between the RX and servo so that it can sense movement and add correction into the rudder servo.

The motor may be an enya if it's a shuttle Z. Altech used to distribute that engine and that's what most of them had unless you asked them for the OS fan assembly. Stick to the 550's.
