[NSRCA-discussion] OS1.40 Idle

[Dr. Mike Harrison]

Tim,
2 things
1.  Your engine and/or idle is too lean.  If your exhaust is anything but almost clear-very slight bit of tan, you are too lean.  
2.  Set your idle trim on a slider on the tx. and you can idle down for landing.  Makes life much better and you have complete control of the idle anytime.
3.  A third possibility is your pipe is too short.  I use the Macs header, ES pipe and 2 more inches, whatever that is.
4.  the high idle can also be an indication the engine is getting too hot.  Look at all those issues.

Good luck 
Mike

  Morning boys and girls. I hope everyone made it home from the Nats safe and sound. 

   

  The subject this morning  is the Idle on a OS1.40. I've been flying this engine for awhile now and I can't seem to get the idle to come down to normal during landing. After the flight and set up for landing the idle seems to hang high for about a minute (or it seems that long), The engine will come down to the normal idle eventually but stays very high then is slowly slows down to normal. Is this an indication that I've got the engine too lean on the bottom? This makes landing as well as spin entry very interesting. J

   

  Any one else had this problem and come up with a solution?

   

  Tim
