Default DX7 Throttle Programming

Is there any way of programming the throttle stick on my DX7 to apply only a certain percentage of power during takeoff and then after takeoff, change to 100 percent?

You need to be more detailed about what you are trying to do and what type of model it is.Acro or Heli? Also to confirm DX7(original) or new DX7s?

If your radio has dual rates on the throttle channel you could program a lower rate for takeoff, but this sounds like a recipe for a crash.
For normal flying you'd be better off just learning to use the full range of the throttle

It's a DX7. I've got a 15X8 prop on a Turnigy C46 motor and when I used a 13X8, it appeared underpowered, but the 15X8 seems to torque it over to the left tremendously right at the end of the takeoff run. This is a trainer aircraft that I converted from glow to electric. Not even sure what the aircraft started out as originally, I think it's a fuselage of an old aircraft and a wing from another (but it's fun to play with).

Simple - don't use the throttle stick as a switch! Advance the power only to the point you need to take off. Don't just jam it to the firewall.

There's a reason that these channels are "proportional". Like the previous poster suggested, don't just nail full throttle, ease it in. Also, if it's torquing to the left, use right rudder to keep it straight.

Wake up your left hand!

Yes, activate a mix with a switch. Mix a added percent of throttle to throttle when you move a switch. It is possible, whether other people want you to do it or not.

Back when -I was helping some of the older guys learn to fly and found that the old Mode 1 flyers -always jammed the throttle wide open on take off
Why?
because it was the only why they had learned how to operate ailerons- they simply never learned to do this unless the stick was against the stops.
Not all Mode 1 flyers - just a select bunch who all flew together . They were originally, reed flyers .
One of em tho was different - and he taught me a lot - he could fly any mode and never trimmed the model -he just flew whatever correction required.
He also was heli/multi/ single engine rated.
