servo selections

[Atwood, Mark]

In my case, the clevis broke with the engine at 1/4 throttle...as Steve stated...too fast to land, too slow to fly.  At first it was ok...just slow circles...but then the vibration started sloooooowly....slowing the engine down.  It was a VERY long flight...and the throttle lowered to the point that a landing was required....just a VERY hot landing.

You should try flying a Quest at full throttle with a YS 1.40L on the front.  My servo did not fail but the clevice on the throttle did, on take-off....  AAGGHH..!!. 
 
I knew I could not gain any height because losing height on full throttle is the path to in-flight destruction. At first large flat circles were flown, but something weird happens. After a few minutes you start to lose your intuitive aileron inputs because you don't do any for so long. A switch in strategy was required. Eventually the plane was led into large horizontal (flat) Cuban 8's. Then you regularly 1/2 rolled in opposite directions. You could also manage the height gain especially when using bigger circles.
 
A 16 oz tank runs a YS 1.40L for 12 mins 34 seconds set slightly fat. Feels like an hour.
 
Throttle clevice $1.45
 
Quest, engine and servos etc. $1250.00
 
Dead-stick landing when tank runs dry - PRICELESS!
 
Regards,

Eric.

I  would hate to think what would happen to my Mintor 1.70 powered plane if it was stuck on high throttle.  Can you say WARP SPEED.... beam my up Scotty.
 
I had a problem with the HiTec mini servo, the cheap one. I went to the ball bearing version and it has served me well.  
I am one of those that has moved up from the coreless Futaba 9101 and 9202 and FMA coreless . 
The difference I have noticed is in these after changing servo's in these area's areas. These are just my personal viewpoints and opinions.
 
1. Rudder 8411 digital.   For normal pattern flying probably really not needed.  For extreme knife edge maneuvers it is a must with its holding power. Good centering qualities.
2. Ailerons  9411 digital converted to nylon gear(smooth operation and minimal wear compared to metal gears).   These are the midsize and fit good in the wing and are a little lighter then std size servo.  The crisp response on these is noticeable now that I am in advanced and doing snaps.  
3. Elevator  8417 digital.   Extremely fast servo. More noticeable control when doing snaps.  Good centering.
 
The coreless servo's worked great but I have learned these things by trail and error and though good advise from many people (BTW thanks to those who know me).  But for the money the coreless 9101 and 9202 are very good servo's and I still use them.  I tried the FMA coreless and although they are plenty powerful they lacked good centering and the pots would wear quickly.

 Mark how long can you fly when your linkage comes off at to high a throttle setting to land but not enough to really use much fuel?  LOL
