Funtana 100 knife edge

[rruhter]

I have trouble holding a knife edge as the plane goes toward the landing gear. Need help with programing my DX 7 to help out. Can anyone offer help or what their set up is to make the plane track straight with programing?
Thanks

Set up a Pmix if you have any left for a little up elevator, start with 5 percent or so with rudder in either direction. I haven't tried it with that radio yet, if you had a 9C I could walk you through it step by step.

At what speed are you trying at. Sometimes a plane won't track stright ar really high speeds.

It doesn't matter about his speed, either way he will have coupling. A plane won't track straight if you thrust line is off.






I have a DX7 and I'll see if I can guide you through it, for I have had to do the same on my funtana. It wasn't that much, like what BarracudaHockey mentioned, mine was less than 5%.

It's just something I've tried that worked for me.

What do you mean? You have tried different thrust lines?

Dont get all technical with this a funtana flys a crappy knife edge like barracuda said just set up a mix it will need more in a left then right knife edge i dont think there is a plane out there that flys knife edge exactly perfect DO NOT change your thrust angles

[flynbye]

the plane does fly crappy ke . i can hold mine for alittle bit but it just not good. my pluse flew great ke. you can try the sfg but i never flew with mine so i cant tell you you how it will work out (i think that why h9 put them with that plane though ) if you need help with the dx7 let me know

My funtana 100 flies a great knife edge. High alpha or high speed and no sfgs. But it is set up a toward the front of the cg so it won't flat spin worth a crap. If I move the cg back the flat spins really flatten out but now it has terrible ke coupling. So I just leave it a little heavy on the nose and have fun.

ok i see said the blind man
i can flat spin really good but can't knife edge for long but i can do a ke loop

what servo is on that rudder?

pull pull or push pull?

crappy does that mean its pulling toward the landing gear only, no rolling?

what motor?

what prop?

[flynbye]

my servo is a jr ds 821 stock setup on the servo (3 in the back) and i running a saito 125 on cool maters 30% heli on a apc 16x4 wide prop. so far the setup is good pull is slow but it's there. i was thinkin about a 17x4 wide o and crappy meaning just not good. i have to get alot of speed i can hold like half the feild but as the speed dies so does the knife edge. the tuna can do the ke but with all the other moves it can do i really just dont care about the knife edge. i just need to get my rolling harriers down
