Futaba Flight Condition question
I tried a search but couldnt find an answer. Ive got conditions set up on a jet and I would like to slow down the speed at which a servo moves from one condition to the next.
I have up elevator programmed upon flap deployment. My flaps are slowed down so I would like my pre selected elevator position to slowly move and stop at the same time my flaps do as to not upset the airframe so much during the transition.
I can do it on a p mix by slowing down the in and out speed on the elevator servo, but cant figure out how to do it when switching conditions. BTW this is on a 12FGA. Thanks

I don't use conditions on my 12FGA but another RCU user helped me out when trying to work
out gear door sequencing.
You can actually slow the speed of the SWITCH (in this case the flap switch) rather than individual servos.
Maybe you could try that & see if it works in both conditions? - John.

You need to use a facility called 'condition delay'. This will achieve exactly what you require.
I can't help you on how to do it on a 12fg as i have never owned that radio( only used a 14 and 18).

Joe you will find in your condition menu a delay setting, set your elevator and flap delay there. Once you have your first condition setup, there is a copy function that allow you to copy the settings to additional "conditions". The 12FGA has incredible programming capabilities.
I hope Futaba releases something similar to fill the gap between the 18mz and the 14sg.

This is how it works on the 14/18mz not sure if your programming is the same.

Bob_B you nailed it man thanks a bunch. My flaps were slowed via the AFR not on the end point page. But the delay in the condition select menu accomplished exactly what I was trying to do. Thanks again, It makes me love this radio
more and more every time I fly with it.

Glad I could help.

Before you try this i suggest you copy your model to memory and experiment with the copy.
Gyro menu settings for your initial flights. This setup features an off position.
photo 1 shows the settings for the off position
photo 2 shows the settings for low gain
photo 3 shows the settings for high gain
for this setup select a switch OTHER than your condition don't worry it is easy to reassign the switch later

These photos show an advanced setup with three rates on your condition switch and the highest gain changing to bank two. You need to change from group to single
Photo 1 is low gain
photo 2 is mid gain
photo 3 is high gain switched to bank two this was by changing the type to AVCS

This is the best advice Bob has given me over the years, especially with the 12FG which is a great Tx. Always make a copy of your model, tweak your settings and if you get your desired result keep it. If not, start over but you still have your original programming.

I noticed when you slow the independent trims (elevator usually), there seems to be a bug with the T18 which actually slows down the speed of your elevator servo, rather than just reaching the required offset slowly.
This scared me and made me opt out of using this function: the danger is whenever you change your flaps deployment state, you basically won't have reactive elevator control for these 2 or 3 seconds while the sequence completes.
Did anyone else notice this?

Servo slow on the flaps from the channels screen, condition slow on the condition screen (don't recall the exact names, but should be more or less like this).
While the condition offset is being reached, the elevator servo becomes very slow, and goes back to normal right after it ends. I set both the condition slow and servo slow to the same amount, so the responsiveness comes back right after flaps stop moving.

It's a software issue and futaba could address it with updates (and maybe they did, I did not update my T18 since I bought it soon after it was released to market).
Anyone with an up-to-date firmware care to test it for us please?
Thanks!

I noticed the same issue with my 12fg when I was setting it up. Mine is not set that slow I think 18 was the number I went with.
it takes about a second for the elevator to move to the set position. I put a few flights on my bobcat setting it up I never noticed any issue at all. But I agree with you I wouldn't go too slow.
