MG800 Round Two !


MG800 round two (12 min 0 sec)


This was originally supposed to be sub 250 , and it was ! Butt .....

The CG was too far back ( 70mm ) and the ESC was faulty , cutting the motor as soon as you went over 3A current draw .

This flight C of G was around 60mm and the battery was a Nanotech 1000mAh 2s ..
Flying weight from MEM was around 268 grams .
New ESC is a 10A Turnigy ..

It has taken a long , long time to get back to this model . I think I can forget about Sub 250 with this one .
The CG would most likely want to come forward a little , maybe start around 50mm from the LE for more stability .
Roll axis stability still bites , and trying to fly straight and level is a little challenging .
The MG800 wants to roll left or right when trying to fly straight . I may need to pull out some expo for faster response time to help tame the roll .
@ 60mm CG , the elevator is still sensitive , I am still @ 100% rates . So maybe lowering the rates to 80% and jacking up the expo a little ?

Flight time with the 1000 mAh battery was around 15 minutes @ 50% throttle , cell voltage was 3.79v when I got home . I ended the flight when I noticed some battery sag ( power sag ) .
