OK, I read and read and read on Helicopters everything FSX offered. I can hover the Robinson 22 to a near stand still for at least 5 to 8 minutes and I have been flying the sim copters for about 15 hours now. So the problem is that when I get in that darn Bell and lift off I almost always get an RPM Low Light and then the thing falls out of the sky!It isn't as bad when I'm flying in Free Flight mode, (but it's still bad enough), but when I try to do the Rhino Rescue or the mission I can barley get off the ground before the RPM folds up. It happens in the Aukland Austrailia mission to but I did manage to get across the water first in that one.Here's what I've got: I have the INC/DEC Govenor switch and throttle twist grip in the display and before I lift off I set the twist grip to full with my mouse, (I'm going on memory of what this function is acually called but I click on the PLUS side of the Plus or Minus option). Then as I start to lift off, (taking up most of the Throttle travel of my desk-top Throttle quadrant), I begin to feel like I don't have enough throttle to get altitude and then suddenly the Throttle twist grip in the display turns to off and the RPM LOW light turns on and I fall back to the ground but don't crash because I'm only 2 feet or so off the ground in the first place.Then if I try to take off again by increasing my throttle, (slow or fast), the RPM light turns on and I don't get Lift. So I reclick the PLUS side of the Twist Throttle and then try again but the Twist throttle immediately twist back to the Minus position and I lose the RPM again. So then I click the Plus on the Twist throttle again but I also click and hold the Govenor INC Toggle Switch for a few seconds at the same time as I add throttle and I finally get off the ground.But I barely get any altitude with any kind of speed and find that I keep having to pull up the nose and then, of course, push it back down so that I don't fly backwards into a tree just to get barely above the tree tops.Then I finally gain altitude and start to the Rhino. I land in the wrong spot and go to lift off to move myself when I lose the RPM, Fall from the sky, Crash and burn.I know there are a heck of a lot of physics to deal with and I have my crash sensitivty set about half or a ltiile more and the General setting at about 90%. The other 2 I have lowered to zero. Note that I get a Low Rpm light on the Robinson also but I can cure that fast enough by simply pulling back on the throttle, (it usually happens because I over throttle or increase too quickly).Can anyone tell me why this Bell is giving me this trouble? I dont have this trouble with the CH101.

... when I get in that darn Bell and lift off I almost always get an RPM Low Light and then the thing falls out of the sky!

Try it again, but don't go full throttle. Go about 90%. If you jam it full throttle, you'll induce low RPM (I don't know why.)

Thank You, I did and this time I moved my "General" slider in the settings tab to a lower position from 90% to about 20% and got much better results. In fact, I completed the Rhino Mission but I didn't catch the paochers because I couldn't see them!, (I think I was to high even though all my scenery sliders are full right and everything is flowing smooth as liquid).But that said, I think what I may have done to help is that I didn't tilt in too much of an angle in anyone direction. I'm going to test that theory by trying it all again but without the "General" adjustment. I was able to get away with a lot more quick movements and hard angles, (in occasional attempts to recover from a mistake I made), when I flew the R22, the Ch101, and the Bell when ever I did a Free Flight. It seems the Mission is a bit more partcular.Anyway, thanks again, I'm going to give it all another test or two.

Try it again, but don't go full throttle. Go about 90%. If you jam it full throttle, you'll induce low RPM (I don't know why.)

Well I found out what the trouble was and decided to go ahead and post it for anyone else who comes up on the same problem, (not many do). Because I could not find anyone who had the same problem as I did when I Googled it, I started to believe that this was a hardware problem... and I was right.I have a CH Products Throttle Quadrant, (my 2nd one in 3 months), and it turns out that I somehow lost calibration of the control levers. They were not reaching full throttle, pitch or mix when I push them to the full forward travel. But it wasn't the Throttle that was giving me the problem, in fact it was the Prop pitch lever!I couldn't understand why the Twist throttle position, (the image of the Throttle/Govener grip displayed on the screen as I flew), kept suddenly dropping a couple of notches seemingly for no reason. But what was happening is that my Pitch lever was barely into the "Full" position even though it was in full forward travel. So when the slightest touch from my hand as I moved the throttle forward or back hit that lever it would pop the twist throtle down a notch or 2.I recalibrated the Throttle Quadrant and that ended my problem once and for all. I know a lot of folks like the CH Products Quadrant and I personally think it's pretty good too. But I also have one of the Saitek throttle quadrants and I liked it better. But at the time I didn't know that I could run 2 Saitek quadrants side by side, (that's what they have that round, flat-bottom bore molded in the side for), and so when I wanted to go to 6 levers I bought the CH Products quadrant.I have had to replace the 1st CH less than 4 weeks after I got it because the 2nd lever from the left started squeaking and slipping real bad, (It also got very loose). Now I'm starting to have the same problem with this replacment and I haven't had it for 2 months yet.In all fairness to CH Products, I tend to 'get into the game' pretty hard especially when there's a problem in the flight, (like a badly postioned landing attempt to name one), and could be sqeezing the 2 left levers that I typically set as engine throttles together as I move them. That may very well be causing the loose lever problem I'm having with this quadrant. But anyway, I liked the hydrolic feel of the Saitek Throttle Quadrants and personally much more prefer Saitek's SST controller program over any of the others I've tried to use, (or figure out), including CH Products.So the new Saitek is coming tommorrow and according to Saitek techs, the 2 units', 6 switches, can be programed to do seperate functions from each other. I mean that if I make switch 1 as flaps up on the first unit, I can make switch 1 on the second unit do something else and the system will know that it's not the same switch, (I don't know how to do that yet though).Well I hope this helps anyone else that may run into the "Low RPM" problem.

Glad I could help.I can tell you that I have the Seitek X52 system (the joystick, rudders and throttle quadrant). I couldn't be happier with it. I too beat them up, and put a few of the old Microsoft Sidewinders into the garbage after just destroying them on military sims. I really like the Seitek. It's expensive, but if you fly a lot they hold up really, really well.Cheers,
