Hey I have a question about the F27Q stryker 180. For those of you using the DX7s, is there any connections in the plane that need to be switched to be able to fly this plane like the DX6i, or is it all in the radio?

no wiring needs to be messed with. Simply select Elevon type in you Dx7s, set your dual rates/expo and you're off!

Oh okay cool thanks! Do you have any expo/dual rate settings you recommend for the stryker?

Thanks for the recommendations on props! My lhs ordered me some but they are orange. . I think I will call and cancel so I can get black ones from gwsprops!

Did he get you the 4040's? I could never find black ones. It seems all the 4040's are orange. It doesn't look too bad on the Stryker! I hate those things on my regular planes, though.

Gwsprops shows they are black so I ordered some. My lhs could only get orange. I suppose a black sharpie would work good enough...

I used a Dx18 for the following but this setup can also be transferred into a Dx6i or above. If using a dx6i, simply use the dual rates given and use one of the several mixes given:

First, below is my personal setup:

-Timer is set to 5:00
-CG in recommended location
-Travel setting for FLP and RRU are set to 70%, all other channels are set at 100%
-GWS4040 prop used
-Everything else stock

High rates:

Aileron: 100% rates, 20% expo
Elevator: 100% rates, 15% expo
Rudder: 100% rates, 5% expo

Middle rates

Aileron: 75% rates, 10% expo
Elevator: 75% rates, 10% expo
Rudder: 5% rates, 100% expo

(This rudder dual rate is set up on the same switch as the speed brakes are on. This is to protect the servos on the rudder when speed brakes are deployed)

Low rates:

Aileron: 60% rates, 10% expo
Elevator: 60% rates, 10% expo
Rudder: 5% rates, 100% expo

(This rudder dual rate is set up on the same switch as the speed brakes are on. This is to protect the servos on the rudder when speed brakes are deployed)

Mixes:

For greater agility/roll rate: I adjusted these mixes specifically as to not overdrive the servos, but to give much greater pitch/roll responsiveness.
Mix 1: AIL>RAL
Rate: 34% 20%
Offset: 0%
Trim: Inh
Switch: (Select desired switch)

Mix 2: ELE>LAL
Rate: 34% 20%
Offset: 0%
Trim: Inh
Switch: (Select desired switch)

For speed brakes, here are the following mixes: NOTE, in order to create speed brakes, disconnect the rudder y-harness from the brick and plug the rudders in their own port. "Dual rudders" must be selected in wing type as well.

Mix 3: RUD>FLP
Rate: 100% 100%
Offset: 0%
Trim: Inh
Switch: On

Mix 4: FLP>RRD
Rate: -100% -100%
Offset: 0%
Trim: Inh
Switch: On

Flap system:
Pos 0: 0% 0%
Pos 1: -90% -10%
Pos 2: 90% -10%
Switch: (Select desired switch)
Speed: 1.4s

For a better hand launch, use the following mix as it gives a little up elevator before you throw the aircraft:

Mix 5: -A->LAL
Rate: 0% 15%
Offset: 0%
Trim: Inh
Switch: (Select desired switch)

For reduced torque effect when throttle is applied use the following mix. This mix was done on a curve mix with 7 evenly spaced out points and was done with the DX18: This mix can be tweaked for your aircraft.

Mix 6: THR>RAL
1: 0%
2: -3%
3: -4%
4: -5%
5: -6%
6: -7%
7: -8%
Expo: Act
Trim: Inh
Switch: On

The following section contains experimental mixes that reduce coupling in knife edge. They can be tweaked for maximimum effect. Note that mixes 7, 8, and 9 should not be used at the same time as 10 and 11.

This first set of mixes lowers the amount of inboard rudder deflection:

Mix 7: RUD>RRU
Rate: -10% 0%
Offset: 0%
Trim: Inh
Switch: (Select desired switch)

Mix 8: RUD>LRU
Rate: 10% 0%
Offset: 0%
Trim: Inh
Switch: (Select desired switch)

Mix 9: RUD>FLP
Rate: 0% 30%
Offset: 0%
Trim: Inh
Switch: (Select desired switch)

The following mixes allow deflection of only the outboard rudder;

Mix 10: RUD>RRU
Rate: -100% 0%
Offset: 0%
Trim: Inh
Switch: (Select desired switch)

Mix 11: RUD>FLP
Rate: 0% -100%
Offset: 0%
Trim: Inh
Switch: (Select desired switch)

The following mixes mix in a little bit of down delection of an aileron when rudder is applied. i.e left rudder input is given, left aileron deflects downwards:

Mix 12: RUD>LAL
Rate: -8% -8%
Offset: 0%
Trim: Inh
Switch: (Select desired switch)

Mix 13: RUD>RAL
Rate: -8% -8%
Offset: 0%
Trim: Inh
Switch: (Select desired switch)



Hopefully all of this helps somebody out. Who says you can't put thirteen mixes into a tiny stryker

WOW!!!! Thats a lot of settings!!!! Obviously, I have some questions now.

1. Are speed brakes necessary? What do you use them for?

2. With Mix 5, do you turn it off right after hand launching?

3. What is coupling in knife edge?

4. What are outboard and inboard rudders?

Sorry if those questions are sort of stupid...first time flying a wing (thats what a stryker is right?).

No worries! Glad to help

Q1: Speed brakes aren't necessary by any means. It's used to slow down the plane. Basically what it does is move both rudders out or in.

Q2: Yes; I turn it off after I regain control of the plane.

Q3: When the plane is sideways, and I give it rudder to maintain altitude, it doesn't fly as straight as it should. It gives roll input when I just want up and down movement from using the rudders (while sideways). That is coupling.

Q4: When I give left ruder, the leftmost rudder is the outboard rudder and the rightmost rudder is the inboard rudder. When I give right rudder, the rightmost rudder is the outboard rudder and the leftmost rudder is the inboard rudder.

Hope that helps
