I agree. Yet perfection is the enemy of good enough. I'm kinda torn between just running what I have now (which is good, and matches some of the recommendations I've gotten) and getting on with trimming out the airframe, vs. fiddling forever with the motor and neglecting the airframe trim.
Tim,,,, there is a reason the "set ups " are there man,, because someone before you tried all the stuff you are,, and found "x + y + z " works,, and ( ok, so I take that back, I am sure you could come up with something no one has tried,,)
cut to the chase,, there are KNown engine setups for that engine, and airframe,, here is my opinion,, if you continue flying with the setup you have, you are not accomplishing anything except burning up that fuel.
from experience,, it may work now,, what is the relative altitude you are flying at and what will it be in July,, ? I experienced on my twister, with a .40FP, just what you are.
real world, to show you how important castor percentage can be, I would tune my FP by adding an another 2% when it got hot, otherwise it would pick up quite a few rpm after the midpoint of the pattern, ( right or wrong that is what I ended up doing) If you can, go flying with someone, borrow a couple tanks of 10% 22 ( 50 castor, 50 synth) and fly a couple flights,, I would use the apc 11x4 to start and it should be I recall 9600 rpm at launch, but you can alter that for whatever your tank config works out to be.
are you really trimming the airframe flying it with a setup that responds differently? Will the airframe trim you are setting up now really be the same when you do "go to the right setup"
I am also extremely jealous, it is just this weekend getting almost ok to fly,,, but the feild is like alabama clay right now, the sod is just a big sponge
Ok ,, I reread what I typed,, It came across pointed, not meant that way,,,, Tim, take it constructivly,, as if we were standing in Salem talking ,,
