Sorry to be a bit thick, but I can't visualise what you're describing here. ie. referenced to machine/horizon, pull/push. Even given that I could understand the movement, I'm not sure how the t-cyclic is different to a 'real' one in this regard. [Keen to learn.]

tyl3r,
Imagine the T bar as a large steering wheel. The student in the right seat has his hand on the right side of the "wheel" and wishes to bank right. He would pull down on the handle. I did this once my self when training for the first time in a robbo, my instructor immediately took control!

The T-Bar cyclic.

[tyl3r]

Sorry, I'd missed the significance of steer in that context, despite Runway101 mentioning it in his post. I understand now. Thanks.

Have seen plenty of dozer drivers, push the steer clutch levers like crazy when the blade is loaded right up. Of course it doesn't mean a damm, it cannot help the power of the machine, and for any effect on the steer clutch they must be pulled.

With a big load that is when everything stops dead with one track not driving, far easier to turn by side tilting the blade to lift one side and hey presto the whole deal turns toward to more loaded side, unlike the TBAR cyclic.

Are you sure your student is not a dozer driver by perchance??

[puntosaurus]

That's uncanny TET, yes he is !

R22 Hp Clutch Wont Engage

Hi there, I own a R22HP. I have been out flying today for over two hours & landed.
Gone to move the machine later on and the clutch wont engage. Starts works fine ive checked the circuit breakers.. any ideas ??? Am I about to get a big bill.

Many Thanks

It once happened to me and it was a faulty micro switch

[IntheTin]

Micro switch won't allow it to turn over. He said it would start but won't engage the clutch....

[Runway101]

I am not sure about the R22, but on the R44 there is a clutch actuator test plug tool (MT558-1) that you use on the 100hr inspection.

I remember that I overheard a conversation a long time ago where the guy asked for a tool at RHC, just in case his clutch on a Raven I wouldn't engage anymore. Call your maintenance center, they will know what I am talking about.

You can also use a paperclip instead of the test plug. The test plug actually just short circuits pins 1-2 or pins 2-3, depending how you put it in. It's that unused white plastic connector (click for image of how it kind of looks like) that hangs out of the aft cowl door. It's fixed to the frame with some cable binders if I am not wrong. Ever wondered what that is for?

However, before doing anything like that I'd get confirmation from your mechanic. I've just heard about it, never used it myself. There could be more to it.

I think that you will find that the clutch circuitry is all same, same for all R22's.

You can bypass the problem usually. if it is not just a blown fuse as ivor points out.

You should have in your kit a short piece of wire to short circuit the malfunction when next you recognize it, so as you don't cop a large bill from ol' mate engineer who has to drive way out to where you are, on a sunday arvo, and do exactly what you can do with your bit of wire, until he gets it back in his hangar on a sober monday!

Get some friendly advice as to how to engage the clutch with the wire, and you need not worry about being left out bush.

Get good advice, because if the actuator motor is smoking it would not be a good idea to then smoke the rest of your electrics.

R22 clutch light in flight

Does anybody know for certain whether illumination of the clutch light with the switch in the "engaged" position can only indicate movement in the tensioning direction? In other words, can the clutch motor run in reverse with "engage" selected?

The clutch light in flight always indicates that the clutch is increasing tension?

This question came up on a written test. I think you need a maintenance manual schematic to answer it...the POH is ambiguous.

Thanks.

Clutch light means it is moving in either direction (engaging and disengaging). If you look at shut down proceedure you leave master on whilst clutch is disengaging and only turn off master when clutch light goes out.

John-( rjtjrt)
Right..but on shutdown, the clutch switch is "disengage". That really wasn't my question.

Thanks.

R22 Dimensions

Hello , I am looking for the dimensions of the R22 HP,Alpha ,and Beta ,I have the Beta ll ones from the Robinson website but am unable to get the others ,any help would be good
Thanks

[IntheTin]

Let me google that for you

Try this one.....

[Tru North]

In The Tin - i like that link!!!

[topendtorque]

In The Tin - i like that link!!!

I concur, excellent.
I see you've only just joined, tru north; Hi, all the best.

If you read back a bit and if my aleing memory serves me correctly i think you will find that 'In the tin' has good reason for posting very sharp comments.

Me i've got quite a lot of experience on heaps of equine models, from the dumbest and slowest to the smartest and that other type the, extremely rough in front of buckle bunnies etc, but never the fast ones. although I did try a couple of times. Mostly I used them to achieve an end.

But when it comes to being sharp, i've yet to meet an ex hoop that ain't.

That is, unless he was just kidding us all along in one post quite some moons ago

New R22 drive belts

I believe there are some new and different R22 drive belts coming into use. Has anyone any early observations or thoughts on how they are performing.

[heli heney]

Mate getting a set and said that they are much harder. Much tighter when fitted too. So all good one hopes.
