NEW PLANE - PROPER TRIM FLIGHT SETUP HELP PLEASE!

[SleepyC]

Ok...

All you BAD ASS 20+ years of expierence pilots, guys that can fly the unlimited sequence with their eyes closed...

I have a serious question for you!

I just finished a new plane, (30% Edge 540) and I want to make the first few flights meaningful and really useful.

Once I get it off the ground and get the basic trim done, whats the best methods for really getting the plane flying straight.

I remember a few posts about watching uplines and down lines and the 45 deg up line roll to inverted.... ect.

Whats the REAL procedure you guys do.

I really have no one at my field that takes plane set up seriously... Everyone takes off, trims out the ailerons and calls it a day... so I'm looking for the REAl DEAL info!

I want to use as little mixing as possible (meaning that I want to do everything in my power to actually set the plane up right), and have a true flying plane.

So LET THE KNOWLEDGE FLOW... I AM A SPONGE!

PS: Even before I start I'll have the Plane CG'ed to instructions, and laterally balanced as well.
I'm really interested in checking the thrust angle, and then generally making it fly as good as it can.

Thanks in advance!

.....would one of you smart guys/gals also explain how to trim out aileron differential....

best article yet....I agree with everything except the wing tip weight part..Enjoy

#1 You must have a proper CG

#2 Depending on the plane I would start with four or so degrees less deflection on your UP aileron ( IE standing at the tail and looking towards nose during a left roll your left aileron would move up 36dg and right would move down 40dg)

#3 Fly away from you and into the wind ( its better to do this on a calm day). Pull to 45 upline and bury the aileron to the left. if the model corkscrews to the left lessen the right aileron or increase the left). Vise versa if the aircraft corkscrews to the right
#4 In simple terms during a roll your lifting wing requires more deflection than the dropping wing

YEA MAN!! Keep it comming.

I'll be printing a field manual from this thread for myself, so KEEP THE KNOWLEDGE FLOWING!!!

The artical by Peter Goldsmith will get you in the right direction and give you a good understanding of what your trying to accomplish. The trimming process never ends. Just about every time I fly I will put a click here or there if it doesn't feel right. Every plane is different too.
The other thing that will really help to speed the trimming process is while your flying have a knowledgeable person help you make the changes while in flight. Forget about flying the maneuvers spend the time and set your plane up right. it will make your flying easier and more enjoyable.

HAHA - Thats my problem... there is NO ONE around me.
I'm gonna have to make the trip and Visit Mr. Greg Poppel and get some assistance! He's probably the closest to me...

I agree with the Imac article that Joe posted. Goldsmith is very good at setting up an airplane for IMAC and 3D. Even the wing tip weight does work but not may people do it. I used to do it on our planes and it helps with things like tracking in loops.

This is my general routine for test flying one of our planes.

1. Check all surfaces with throw guages
2. Take off and get a fair amount of altitude
3. Basic triming (straight and level kind of triming)
4. Check dual rates and expo's (if not happy land and adjust)
5. Knife edge (see if it pulls to canopy or belly and if it wants to roll out, each direction)
6. Upline check (do an upline, agian see if it pulls to canopy or belly and if it wants to go to the left or right with rudder)
7. Downline check (pull throttle to idle and see if it pulls to the canopy or belly)
8. Stall characteristics (get plenty of altitude, pull throttle back and pull full elevator and see what it does, does it drop a wing? come straight down? want to snap?)
9. Land, go over the airplane, and loctite the stuff you forgot to loctite before

When doing your triming I suggest having someone there with you to remember the things you need for knife edge mix and thrust (even better have them right it down so they dont forget)

My maiden flight is generally pretty tame and the first three of four flights are all trim flights in which I fine tune what I have done. If you can adjust your mixing while flying it saves a bunch of time but I dont recommend it for most people.

Sleepy, call me or Greg. We can go over it with a FINE tooth comb!!! Get it all dialed in for ya. And you will only OWE us dinner!!! Hows that for fair barganing??
