Anyone know of a newsgroup for Robinson mechanics? Is there enough interest to start one? Tom

Anyone complying with Service Bulletin SB-95 outside of Robinson's, did you need a 337 form or not? I believe one is needed, however, I would like to know what others are doing. Eric D

Anyone jumping on doing ths SB91? I'm a little hesitant in anticipation of a near future change, again.

Just read about people selling run out Robinsons for continued service. Anybody know just how wide spread this pratice is.

Rocks Thrown at Border Patrol Chopper Aug 25 3:31 PM US/Eastern YUMA, Ariz. Illegal immigrants threw rocks at a Border Patrol helicopter, forcing the pilot to make an emergency landing when one of the rocks damaged the rotor, the agency said. Neither the pilot nor the Border Patrol observer was...

That's right..... Your fired. Pack up your bags and scram. Your no longer needed. R-Max is on it's way to replace you. Lighter, smaller, newer.

HELP!! I have an old 28 vdc Grimes Rotating Beacon with an all red cover that does not work anymore. It appears the motor (Barber-Coleman)is missing a brush and spring. Does anyone know where I can get another motor? If not, then does anyone know where I can get another rotating beacon? Exact model...

Does the Rotax 'After-Muffler' part 878967 really work, reducing noise?. I'm running a Rotax 503DC on my Gyro and constantly operating between 6000 & 6600 rpm. Interested to hear from anyone who has fitted / heard one operating with after muffler Thanks in advance, John

Hi! I am trying to help my friend find crankshaft gear and the adapter plate for the Rotax 532 reduction drive. He just bought the following of e-bay: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=4632954... and needs the missing parts. I've found a schematic for the drive...

Interesting balance job. New Safari and initial balance run. Blades rough tracked at 300 rpm and a balance run made skids on concrete. Added some washers using the "Add Opposite" rule but not much change and phase angle stayed pretty much the same. For an interest, put the helicopter up on...

I just had a strange one. I have been balancing my rotor system using a DSS balancer where I would get the ips and phase angle measurements, turn the rotor to the angle with respect to the photo cell described by the phase angle information, then sight over the velocimeter and add weight to the...

What are the limitations on rotor brake use? Can you throw off the lead-lag if you "stomp the brakes" too hard? Bill

Ever had an actual one? This board is so freakin dead and boring I left months ago. This is another attempt to revive it. Any takers? I've had several actual in flight emergencies in helicopters worldwide (in addition to the phyxed wing side) and survived them all. how about yor stories? Ol S&B

Someone posted a note on rec.aviation.piloting asking about rotor IFR minimums to which I responded. How many here are rotor IFR rated? I got my rating back in the 80's and the CFII/R in 1990?

I have been trying to model rotor wake using vortex methods, I am confused regarding the lift coefficient, should the value of the lift coefficient obtained after computing the lift using the bound vortex strength of the blade be the same as the sectional lift coefficient of the airfoil?

Hello all, This is my first time posting here, but I figured maybe you all could help me out with a question that has been nagging at me for quite a while. Forgive me if this seems like a stupid question. Here goes: Does a helicopter, without lateral movement, have the ability to fly down, or...

I just found the following rotorcraft chat group that does delve into some of the engineering problems dealing with rotorcraft. I found it to be an excellent source of information. It is /www.eng-tips.com and look for rotorcraft engineering. Stu Fields

I am new to message boards so bare with the rookie. I am ASEL finishing my instrument soon then trying to complete the CFI. I foresee a job promotion in my work department in the relative near future which requires ASEL-CFI plus minimum commercial helicopter rating. If I can get this rating for...

Hello, Do anyone knows any GOOD rotorcraft flight school in the area of philadelphia, also delaware, NJ considered.. Thank you
