Bit of a long post ... apologies ...
I'm looking for some advice on beginner's pitch curves. I'm flying a Trex 550e fbl with one of the new Scorpion 50V ESCs (the one with a good governor, apparently, unlike the previous Scorpion LV ESCs) and the stock Align motor.
The machine is set up with +12/-12 degrees of pitch (per the mini vbar set-up process), and I'm looking for some pitch curves to tame things down. I'm flying with the governor switched on.
A very capable friend has set up my Tx with straightline (excluding point 1 which is 0%) throttle curves of 70% in normal mode, 75% in Idle 1 and 80% in Idle 2 (although I'm only using Normal mode just now). My pitch curve across all three modes is 23,39,60,78,95, which equates to -6½ ,-2½ , +2½, +6½, +11 degrees of pitch.
I've been learning to hover tail in with that pitch curve, and doing OK, but I feel that the -6½ is too much for me at the moment. I've bounced a few landings, but the boom and everything else is still intact ... so far! Certainly even just spooling up, the carbon rods on my training gear are being pretty bent with the negative pitch.
I'll check with my friend, but I understood his thinking was along the lines of "its best for learning to keep a linear pitch curve across the range of stick movement (hence these points, and also the recommendation not to use expo), and to use a curve as close as to what I would use as I progress in the hobby". I think, however, that he might have thought my mechanical set-up was giving me -10/+10 degrees of pitch, which would equate to a bit more reasonable -5½, -2, +2, +5½, +9 degrees of pitch.
Anyway, a long story to ask the following questions ....
- Is 70% governed throttle a good Normal level? Seems fine to me when hovering, but what would I know!
- Because I'm running governed head speed, I don't need to be switching flight modes when I start in forward flight, right?
- Throttle percent increases across the flight modes – that is increasing headspeed, right? That makes it more agile? I've read a faster motor is more efficient, but I presume it willstill reduce flight times if I up the head speed? I'm currently getting a wonderful 8½ minutes on my 30C Turnigy 5Ah batteries
- Would it be a better option to use a gentler pitch curve in Normal mode, say -2 or -3 degrees at low stick for my hovering, and then switch to something more like my existing curve in Idle 1 which I could switch to when doing forward flight?
All thoughts and suggested Newbie pitch curves that will stand me in good stead as I progress would be much appreciated.
Many thanks.

What you are trying to do is make it as nice below centre stick so you dont ram it into the ground . You could always just get it so its pitch range is -2 to say the full +12 ... the choice is yours .. Looks like its the pitch range below centre stick thats giving you problems .. Just alter it until it feels comfy ....As for the not using expo... its there for a reason and TBH I still use it and so do alot of other pilots 
.. Try putting -20 if futaba and + 20 if spekky and try that
