Suppose it depends how you hold your transmitter, I fly Mode 1 (throttle/Aileron on right stick) and have never had issue moving sliders by mistake, thats why they are at the top and out of the way.

Best of luck with your new transmitter, which ever make it is.

Cheers. The Optic 6 is a nice set, its just spoiled for me because it doesn't work as documented in a couple of ways which happen to matter for me. I can see that Mode 1 vs 2 makes a difference - I'm Mode 2 and with primary controls on the right hand, I really want to use my left for secondary functions.

There are no secondary functions on a FunCub. You work with throttle and rudder most of the time too.

Here's a video from our recent float fly. I was chasing my buddy's T-28 around with my FC.

I'm sure you're right. I'm too lazy with the rudder. Actually by "secondary" I meant things like flaps, gear and airbrakes. All the same, taking your point I am happier letting go of the throttle/rudder stick for a second or so, but hate doing anything else with my right hand. A hang over from learning initially on two channel gliders maybe.

I have not used flaps before, so I admit my ignorance.

How do I make them move together and in two steps?

UpnDown,

First, I have to ask, how did your parents know to name you for the problem you would now be having?

The issue is that the flap servos are mounted the same way as the aileron servos, with the output shafts mirrored about the fuselage centerline. When mounting flap servos like this they will always work in opposite directions when fed a common signal. Instead you need to feed them two different signals. This is typically done by using individual channels for the two flap servos, using a reverse rotation servo on one side, or by using a y-harness that reverses one of the servos electronically. The Maxx Products Miracle-Y sells for about $20.

Here is a 3 year old video of a T28 with 11x7 APCE running 35-36C. The pack was 18C 3S 2200. The whole flight was WOT. The pack only lasted about 20 flights but I didn't care, I was having too much fun. That motor survived serveral crashes and shaft replacements. Two years of abuse. Of course, not every flight was like this. Amps were 36-38.

Yup. Everyone should have at least one really FUN plane like that. Your eyes are better than mine. I would have lost it on the first vertical.

A "Y" harness will work for #'s 1, 2, 4. (unless you want to modify the insides of a single servo - not for the feint of heart). Then, you can use the AUX channel to control the flaps. What radio you have is of no consequence. So, here are your choices:
1. (most popular) - Flip one of the servos over and cut away a little foam so it fits.
2. Get a servo reverser for one of the servos. (this was my choice).
3. Reprogram your radio (if possible) to accomodate flaps control on two different channels (i.e. AUX1, AUX2). Even though my radio will do this, I opted not to use if because if it fails in the field, it is a pain in the neck to remember how to reprogram it.
4. Reverse the leads to the servo motor. (not recommended for beginners).

I use ailerons and elevator in my right hand. All the secondary functions are handled by switches. So, I am not clear on your problem. Since I rarely use the rudder, can that meet your needs if you do the same thing?

AJ,

On that day of that flight the weather and sun were in a perfect position to keep orientation of the white T28.

Warning!:

Reversing the leads of the servo motor will make your servo run full speed to its end position and may damage your servo gears.

In order to reverse a servo, you need to swap the motor wires and the outer wires of the servo potentiometer.

This was a routine procedure 30-40 years ago
However
moving the servo cavity over is soooo much quicker n easier
and perfectly safe

Servo reversing on some of the newer types via wire swapping is made a lot more difficult as the potentiometer/motor is directly soldered to the circuit board.
