| You want it warm but not hot. Whatever needle setting that takes. Depends on your fuel (oil and nitro content), muffler you're using, and the weather.

i agree.. you would rather be a little rich then lean. too lean and you will blow a hole in your piston... ive seen this happen 4 times... once to me.
I think a good rule of thumb for starters is keeping it rich enough to be able to hold your finger on the back plate for at least 4 seconds.
I use a temp gun to get my temperatures right for tuning. I try to run about 210 on my os hyper 50, and 220 on my novarossi 57. i take the temp on the head.
also, this is a really good way in my opnion to tell if it is too lean... spool it up and lift it off the ground... hover or fly or whatever for about 30 senconds. hit throttle hold... if the engine sounds like a dirtbike when they get off the throttle you know the sound... it is too lean.. the sound should be smooth., you should get a headder tank, or an OS bubbeless clunk. (get the clunk in my opnion)
I find the harder I "throw down" at the field... the more peices i have to pick up. |
