I hope you didn't misunderstand me...I use program mixes in the Tx, not external mixers on the servos.

Anyhow, good luck with the build. Are you doing the TV version or a single motor config?

I didn't misunderstand but thanks for the concern. Given my desire to add gyro stabilzation, I have to move the mixing onto the airframe.

RX >> Gyro >> Mixer >> Servos

I'm wondering if you could get the same end result with only one aileron servo and two elevator servos. I have a DX-7 and am not a fan of its 3 position flap switch. I only use flaps now on my F-14 for wing sweep. Never used my flaps that much on my old Eclipse 7 so it would save me one servo for rudder which I do use. I'll have to experiment but at the moment I don't have a bird with dual elevator servos other than the F-14 and that won't help as it has no ailerons.

Sure...I just didn't want to do it like that so I had the option to mess with flaps if I wanted to. I also have a plethora of other mixing options with one independent servo for each control surface.

I don't think this model is suited for one servo for both ailerons if you wanted to do that. Where would you put it? How would you link to the control surface?

hello everyone,
i finally mustered up the nerve to buiold one. from the initial cutting of parts i almost got frustrated due to the number of pieces, then i said to my self, i didn't have to finish it in one day.....so i took my time and finished it in a week
AUW 24 oz
power set up: grayson smj, 40 amp esc, 6x4 prop, 2000mah 25c 3s and 2 9g servos

a bit of concern arose after reading through, would elevons as the only control measure pose a problem? would i need to install ailerons too?
TIA
Carl

Ohh man she’s going to be really fast at 24 oz with the mega jet… you don’t really need ailerons elevons is just enough. Try it out with only elevons you could always add the ailerons later if you’d want to. Now how about some pictures.

Pretty much the same way Steve configures his rudder servos on the twin vertical stabilizer designs. Just behind the battery compartment and then run pushrod wire through the flexible antenna/pushrod tubing. I have plenty of aileron torque rods left over from departed GWS warbirds that work very well or I make my own out of brass rod and sheeting.

Tips and tricks are all through the thread. The assembly instructions located at 6mmfly.com are also very helpful.

Here's a link to the scratchbuild version of the Su-37 construction guide, with everything you need to know to build this bird. The manual at 6mmflyrc.com covers the kit version, which is similar to but slightly different from the scratchbuild version.
