Nose pitch's up

The hatch fits good just like the original.

Gentleman the weather was permitting do do some accurate testing today and I found out like many of you said it needed more up thrust.Along with that I also found that it was a touch too tail heavy.I also fine tuned the throttle curve and now it fly's like a totally different airplane.These changes also dramatically helped finding the sweet spot for torque rolling.
Thanks for all the pointers.

Thanks for letting us know. Glad you got it working for you and are very happy with it. I have the 36% PAU Edge and I really enjoy flying it around. Also had their Ultimate, which was fun to fly as well (till it met the trees).

Glad to see you have solved your problem. Nothing like flying a plane that does not fight the pilot.

Some very good info in this thread.

I would just like to add a few things to I have learned for consideration as well.

First off, most of the time when we talk about CG it is usually in relation to some specified fore or aft distance from the wings leading edge or some other similar point of reference. The actual CG is a point within the aircraft that would allow the airframe to balance similarly as a propeller would balance on prop balancer…i.e. in any position from which suspended, it would stay put…

Secondly, thrust line can have its own effects during power applications. A high thrust line designed plane, such as the PAU Edge will tend to act more nose heavy under pull and more tail heavy under the brake of the prop.

With all that in mind, consider that airplanes with a lower (as opposed to fore and aft) center of gravity and a high thrust line will have a greater tendency to pitch up under the prop braking when the throttle is reduced…especially if power is suddenly reduced.

Now, two things can be done to reduce this undesirable effect. Put more of the mass higher (to raise the CG) in the airframe and/or use a prop with less braking action and of course, reduce power slower.

Of course, moving the CG forward will also help reduce or cover up the symptom but an overall CG (fore, aft, high, low) along with best prop choice and power application will pay the biggest dividends.

BTW I have found a small amount of up thrust in high thrust line airframes is also a benefit but anything over 1 degree is probably to much for this Edge.

Anyway, good luck and blue skies to you.

That was some great additional info.It sounds like you've had some experience with the Edge.As of right now I'm very happy with the flight characteristics but I may try to tweak it a little more.

I am just a 'no name' unlimited flier but heres the technique I use to set up my models for precision flight.
The order you do things is very important, you need to follow the sequence logically........

Just chucking mixes in is masking a problem not fixing it. I have never had to use a downline mix..........

Anyway heres how I do it.
