KK2.1.5 Question

[jwander92]

I'm new to quadcopters and purchased a kk2.1.5 board to use on it. I can get it to fly alright and hover pretty well using the self leveling.

However, when I try to fly forward quickly it always drifts to the left a fair amount. Is there some tuning I can do to fix this? When I fly forward slowly it doesn't happen near as much.

Thanks

Interesting...

When it drifts, does it change heading or or is it a pure side-to-side movement?

If you release the sticks in autolevel hover, does it have a tendancy to drift there In any one direction?

In fast forward flight, how high up are you on the throttle?

 

[jwander92]

When it happens, the front left motor dips lower than the front right so it turns in that direction.

When i release in autolevel, it hovers pretty close to still. Not much drifting at all.

By fast forward flight, I have the throttle just over half but I have it leaning forward (the elevator on my Tx) as far as it will go. I have the stick scaling for the elevator and aileron set on 50.

Sorry, I have to ask . . . where is the throttle when you're hovering? If Fast Forward Flight (FFF) is hard over(even at 50% scaling), but you're still only at 1/2 throttle, then I don't understand why you're not plumiting to the ground, not just dropping a boom.

I have a suspicion what's going on here, but not positive . . . I think this is a resolution issue, and the front motors have slowed to the point the board is having touble stabilizing the platform becasue it doesn't have fine enough control . . . There are ways of fixing this, but if it's not your problem, it will make it worse

that's your throttle stick scale? What motors/props are you using? Have you measurd the All-Up-Weight (AUW)?

 

[jwander92]

My throttle stick scale is 90. When I'm hovering, the throttle is probably 25% of the way up.

I'm using iPower 2217q motors with 10x4.5 props. My weight is around 2.5 lbs.
