Restoring a Bensen, where to Start?

[Bob]

So how is your Project comeing ? been a while !

I just got done re working my gyro again and i am quite pleased with the results, I even took her out for a couple of short Crow hops the other day ! everything seams fine ! <GRIN>
heres a pic of "Persistence" my Scroungy Gyro

It looks like something from HG Wells, are you sure it won't time travel?

I have newer post around the board search for Xorandor.

[Bob]

No I'm not sure... if it does I hope it takes me into the far future not the past ! HAHAHHA !
I took her out today and tried ballanceing on the mains.... man thats Hard !
Like trying to wheelie on a motorcycle but there is no engine to wheel to ballance against ! ... gott'a be a nack to it ! i think its the stick position.... gott'a feel the Push of the rotor I think ...
was fun trying it today ..it was real calm for once ! I have to admit I didn't do too good ...but I'm getting the haing of it ...I think !
Post a Pic there Xorandor ! lets see how your comeing along !

C ya !

What is the typical range of motion I should expect on the rotor head?
I feel that what I have is too limited. Also the rods that link the joystick to the rotohead are of different lengths, is this intentional? could there be a valid reason? I've included some recent pictures. Oh and I finaly got another propeller 49.5 X 26.

That notch cut (filed?) into the pitch bar is something of a worry - can't tell if it's been adequately radiused... not a good idea to have sharp concave edges in aluminium - they spawn cracks.

[Xorandor]

Well as it is I'm not getting any incressed range of motion from that notch. I'd need to make it about an 8th to a 4th inch longer before that other component would rest into it the way it seems was intended. Does any body know the approximate range in degrees the rotor head needs to move from all the way forward to all the way back?

And what about the contol rods are they suppose to be the same length?

Here is a link to the section of Ralph Taggart's site where he discusses rotor setup. I think the answer to your question is in there.

I agree with Banaari - that notch is worrisome.
