hi,

Today I was flying my Sceadu 50 and I did really good. I did fast forward and I even did some stall turns and 540 stall turns

The weird thing is that I start adding pitch the heli wants to tilt forward. I am forced to hold him back. Is this normal when you do fast forward?

Thanks.

Out of trim...
I would venture to say you have a slight out of trim condition or a hidden mix?
Have a flying buddy look at your cyclic while you are hovering and see if you are subconsciously holding back cyclic in a hover.
Also check your balance. You many be slightly nose heavy (hard to do since the Sceadu is tail heavy to begin with)

hum
I thought it was trimmed, but I can check again.

I have no mix enabled what I know.


I'll check the balance, but I've heard it is tail heavy already.

Could there be a mechanical mix somewhere?

Thanks.

Shouldn't be...
There is no place I can think of that would cause a mechanical mix unless you are binding in the mixing arms somehow.

Check your paddle alignment. This usually solves pitching up in FFF for me every time. They don't have to be out of alignment very much to cause you problems. Get a set of paddle gauges if you don't already have one. I think my guages have been one of the most significant and inexpensive set up investments I have ever purchased. I was amazed how much better a bird could fly simply by tweaking a paddle the slightest amount. It really does make a huge difference, and you cannot see the difference without paddle gauges.


Also, try aligning the paddles to the swash plate when you make your adjustments.

Glad to hear it...
I flew today also
Bad news had my first inflight flame out.
Good news had my first successful auto.
Even worse news. Took me 3 hours of working time to find the problem.
Glad someone had a better day at the field.

Not 100% sure...
Well it wouldn't run past half throttle and was running real lean. It has been hot here so I figured the heat was making it lean out. I richened it up and same thing. Did this for the better part of an hour start re-start....
Thought it had some dirt in the carb... Nope none found.
Hole in the fuel lines...New lines same problem..
Ok rotten clunk line....Replaced (it was squishy)....and while I am at it the fuel looks kinda old...so break out the new gallon and
Wala it worked!
Best I can figure I had just done a flip (ok kind of a flop) before it flamed out so I think the soft clunk line folded (didn't look when I pulled the tank Duh!) the line and that was causing the 1/2 throttle flameouts (not enough pressure to push the fuel through the kink) and the fuel was probably not quite up to snuff since it has been in the heat a couple times this week.
So far the driveway test hover says it is fixed. I will try a test hop on Thursday.
Really bummed too. My wife had come out to the field to watch for the first time in a long time and was hoping to put on a show. She hasn't seen me do anything but hover. Figured the Sceadu acted up just before she go there. She didn't even get to see my Auto.
Oh well convinced here to go to the fun fly end of the month.
