Trex 450 DFC



No buddy, haven't flashed the ESC.
Made a lot of mistakes during the initial build, which caused the issues I mentioned earlier (like heat up/wobble etc). Now, that basic mechanical set up is done, its working fine. I am getting around 8 mins of flight time and have to put back around 1600 mAH. So, surely it has potential to go higher than 8 mins.

The gain settings mentioned aren't really tuned. I even went up to 220 P gain (aileron/pitch), but I could not see the high frequency wobble as seen in the kk2 setup videos. There is another thing to look at when tuning i.e. the bounce when the quad is landing. If gain is too high, they tend to bounce more. So, I noticed at 110 there is minimal bounce, hence settled on it.

Finally DT750, I don't have anything to compare it against, but they seem very good. There is no vibrations, barely warn after 8 mins of operation and overall quad is stable.

Thanks for the review, was waiting for your comments on dt700/750s. Smiley
It seems only my dt700s were poorly built (but even my second batch of motors was bad)

Very nice quad
I am also planning to make one but.... I have a big issue
I want to get my stuff from hobbyking
so, when I tried to use my visa card... payment was denied by bank
they said you can't make any payment in china
I tried from various banks and diff types of cards but no use..
and hobbyking said they pickup western union amount after 2 weeks... it would be too late
any ideas??
 Huh?

yes buddy - all inclusive. One thing to note, at that time, customs processing and exchange rate was much better compared to now.

no 'sir' please  Smiley
