Any of you guys with turbo ships:  What is the normal inlet air temperature your seeing?   Mine is upwards of 200 after a 15-minute hover.

I have an adjustable cooling fan on my bird.  Don't know who made it.  It's not identified in the logs.  Does anyone else have one?  If so, what AoA do you set the blades to?   I think mine are set too high and the blades are stalling and sending disturbed airflow through the radiator.

Hi All,

what size was the Alternator in the later model Talons/Phoenix A600's?

i have a 37amp Prestolite 8AR2169, i see later 51Amp became the standard?

i would like to eventually do an Electric water pump upgrade aswell as not worry about any charging at Idle or overcapacity issues with lights/avionics including a small electric heater blower fan robbed from an R22.

here are some graphs i've found for the 37Amp and 65amp 8AR series prestolite's

For those familiar with the MicroVib II balancer system, Please have a look at the screen shot showing a solution for the lateral lead lag adjustment and explain how this solution would be applied. I have an idea of what needs to be done but I would like to confirm with people familiar with this system.

Now that the threads are getting longer, we need to have a button at the top of each page allowing you to jump to the newest post on each thread.

Any particular engineering reason the hole spacing for the ballast weight mount to the weldment in the tailboom have different edge clearances?

I'm building an A600 from parts gathered hither and yonder.   Most Brand new parts, some previously installed but none ever completed.  This is the case with this mount.   It was previously drilled and the hole placement by the previous person was 5/16 on both edges.   The drawing show a different edge clearance on the forward hole?     I'm thinking a 16th of an inch in this application is not critical as it still falls within normal edge clearance limits.

Good afternoon everyone, 

I've attempted for a few weeks now to get in contact with the owner of the Rotorway Owner's Group forum (ROG) via email and private message without any success. While it'd be great if we could upload the archives here for a larger source of information available to all users (and the public), it seems unlikely. If anyone is able to get in contact with Ron to see if he'd be willing to let us migrate the archives onto this forum, that'd be great!

We have had a T/R belt failure just after coming in to land in the hover 2 up confined area, total destruction of the RW.
Just wondering if the Vee belt could be upgraded as there has been a lot of improvements in belt technology.
this came up in a google search as maybe a better belt for our application.optibelt SUPER XE-POWER PROHigh performance wedge belts - raw edge, moulded cogged

I have a long standing intermittent but consistently occurring issue with my MGL RPM-2 engine tachometer display.  Using the dual arc setup once I reach operating RPM, the engine RPM intermittently drops off and then recovers.

I run a Fuel Tech computer on a Joe Huff turbo.  Engine RPM on the Fuel Tech display is steady.  Rotor RPM display is steady. 

I have done all the standard troubleshooting including purchasing a new unit, adjusting the sensitivity, swapping the display sides, changing the increments, etc.  On some flights it only occurs once, and on other flights it is consistent.  I have yet to have a flight where it did not occur.

I am to the point now where I think I am going to have to chase the signal wire all the way back to the origination which will require removing about every cowl and wire bundle.  That will have to wait until next annual.  

In the meantime, do any of you MGL experts have any ideas I might try?
