Your first mistake was changing the thrust angle. It was perfect out of the box. Pull both washers out and re-do your CG and life will be good again. One thing I noticed after building a bunch of planes from other manufacturers is that while those ones often need tweaking like what you did here, the 3dhs birds never go to production until they are convinced it's going to be awesome without the consumer having to figure out how to make it fly right. If you had an issue that you thought was the thrust angle before you just need to go over your setup again, it's something else.

Good luck,

I went from foamies to balsa its not an easy transition but its a rewarding one. It will make you a better flyer all around

Guys, make sure you are getting as much torque out of your rudder servo as possible by maximizing the throw with your radio. End point adjustments should be maxed as well as dual rates. When I set mine up initially I did not do this and many of the kind folks who post here helped me figure it out. If you set it up without doing this you may find that your rudder is weak and you will get very poor KE performance. You should have the cables as far in on the servo arms as you can while still getting enough throw. It is much better to get more throw by making the servo move farther than to get it by using a super long servo arm. That being said, I still have a long rudder servo arm, I just don't use the outside holes. Once I changed this I got better performance all around and my confidence in KE was greatly improved as well.

Quick question for you guys, I have a CC ICE 50 (non lite version) that I have spare right now as I got a ICE 75 now in my Striker. I was wondering would the weight difference between this one & the lite one make a different enough to purchase the lite version for my soon to arrive 1.5 buck huck ?

about maximizing throws... dx6i i understand in dual rates i cant go over 100% but only travel adjustment to 125%....

No thrust angle changes needed in 3dhs planes.......any of the 15 or more I've owned. It's NOT advised to second guess the angles chosen by Stoops or AJ....If you make any changes, it'll affect other aspects of flight significantly....FOR instance...added right thrust will make inverted harrier WAY harder on the left rudder and push-up from inverted harrier will require TONS of rudder....as well as changes to KE flight with any up/down thrust you've changed.

Build and fly.....that's my favorite thing about these planes....no "trial and error" trimming required.


Here's maiden flight video from yesterday of 48edge #2... Enjoy.

+1 on what the others said. remove washers, check the elevator linkage and servo for slop.

I believe the 3dhs standard for motor angles is:
1 Degree down and 3 degrees right

They build this into the motor box so no need to add any further inducement.

Man... I had a blast flying this morning. A little chilly but no wind. I'm getting better and better every time I go out. I got my hovers right down on the deck today. Awesome! My harriers are getting better to. Almost ready to try inverted harriers.

I love this plane and I'm having a blast with this hobby. That's what it's all about right?

has anyone had a problems with servos moving a lot more on one side than another? and yes, subtrim, trim is 0 and travel adjustment is the same on both sides.....

is your servo arm centered? if you check everything else that you mentioned, the arm isnt centered or you have a stripped gear
