I finally succeeded in flying my quad.

My second quad was-is a VooDoo 280 racing brick. Although it has no redeemable aero nautical abilities it screams around the sky until an immovable object hits it. With me flying that is quite often- lots of prop changes...

I have learned to fly my wifes Syma XC5-1 rather briskly and wanted to somehow make my 280 respond in a milder fashion like the Syma. After adjusting the curves on the throttle, yaw, pitch, and roll I never felt comfortable at this point in my flying career with this ballistic machine. Not until today. I have been waiting for a 2s battery I ordered to arrive and with the installation of this I finally accomplished the task of slowing this thing down. My abilities are just not up to a 3s battery and the power it delivers into those motors (at least in line of sight flying). Yea it still is a brick, but a manageable brick now instead of a flying machine that taxes my thinking processes when things get so fast. Now I think I can develop some reactions that are natural rather than panic stricken reactions causing so many prop changes.

I think I have found a way to develop a learning curve for this thing...
 
Hi Mate well done thats one way to tame the beast, can you adjust stick travel on the FCB or transmitter this will tame it on the 3 cell battery
 
Hi you cant adjust throttle curves this must stay linear 0,25,50,75,100
Go in to servos on the transmitter then find servo travel this will be 100% ,reduce this to say 55% if it to low up to 60% ( only do this if you cant adjust stick scaling on the flight control board ) this will make the quad more tame , if you want to fly in wind your have to set up a switch so you can jump between how much travel the servos will get , if you want to do this let me know I will tell you how
 
I see what you mean, that would technically adjust the maximum throttle to the same value as lowering the actual voltage of the battery- which is what I accomplished by changing the battery to a 2s. The one thing I accomplished was to change the yaw, pitch and roll along with the throttle at the same time.
One advantage I gained this way was to install a 2200 MA battery in place of the 1300MA 3s.
 
HI Ram NO mate your missing the point, dont touch the throttle this must stay as a linear curve of 0/25/50/75/100 as the esc are set up to know zero and full throttle when you calibrate them , the FCB controls the motors rpm to fly the quad , but on a tricopter you have 3 motors and a servo to tilt motor 3 , Now the flight control board can control servos or motors , so going into the transmitter and adjusting the servo travel range what you doing it controlling the amount of signal the motor will get, so normally its 100% but to tame the quad we cut this down to say 50% half the signal range in the flight control mixing, so the quad will not have as much angle of attack this makes it more tame and not as fast , so adjust servo travel down from 100 to say 50 and try it , We normally leave transmitter alone and adjust stick scaling in the FCB ( this is the same thing stick scaling and servo travel)
 
Well this is working too well compared to previous flights so I'll just leave it as is for a while. As a side note I changed from 6" props to 5" and the quad would not lift off the ground with the 2s battery. I was trying the smaller props to see if it were even milder in response- well its too mild!
 
Hi the problem is rpm to work it out its the KV x the voltage = the rpm so 1000kv x 11.1v(3 cell) =11,100
you only get 7,400 rpm from a 2 cell to slow for lift needed
