Downwindleg, ran out of space on my DX6i and bought a DX8G2 over the summer, noticed the same thing and had the same awakening. Depending on wind speed and direction, a couple clicks on throttle trim and bingo. Great stuff.

Hi Dan, I'm assuming you've already programmed flaps to move? I don't fly Spektrum so I can't help you with your specific radio from direct experience. I Googled the instruction manual for the Spektrum DX18, and page 25 covers Mixing. Go to the Mixing menu, select Flaps and Elevator as the two channels to be mixed, then adjust the relationship between them by changing the percentage field. A Positive or Negative value will invert the relationship. Visually observe your elevator moving (up or down depending on the value) in relation to the flap being moved by your control. Adjust that value accordingly until the elevator moves the direction and degree you want for the given flap degree of movement.

I've read different opinions on the direction of the elevator when flaps drop. Some say up (I can't understand the logic here), some say down. Down will help prevent the balloon effect. Pipe in yall....:dodgy:

Down.

Just installed the upgrade struts from Freewing. Very cool, glad I did. I filmed it so anyone interested be looking out for the vid.

Neat! I'd like to see them in action! We worked hard on those little buggers.

Starting point per the manual is 4mm up.
Take off flaps 1.5 mm down elevator mixed in.
Landing flaps 3MM down elevator mixed in.
Page 14 in the manual. I started with those numbers and adjusted according to my preferences.

Here's one of my flights with the strut/wheel upgrade.

Nice flight Lon. Man, that baby really hauls in the tailwinds!

[Grossman56]

Thanks Sky Wolf!! It does have plenty of power....BUT, one of my winter projects is to not only to put a new paint job on her, but also install the sport upgrade motors. Installed the new 880 motors last night!! :)

They are the smoothest rolling wheels/retracts i've had on a plane.

Thanks guys for the flap mix help. Actually I figured out my problem shortly after I posted. Originally I had not set up the plane with the flap system. I had slowed the flaps down in the servo setup menu. So when I went back and set up flaps in the system menu then tried to mix flaps and elevator the two setups were fighting each other. I got rid of the flap speed setting in servo setup and the flap/elevator mix works fine. Thanks again for the help.

The 18 is great radio. Just keep playing with it.

I used the entire retract system with the strut upgrade for my scratch p39 build. I had to cut down some of the springs to make them workable for my lighter plane, but they are awesome all around and when I get this plane for FPV, I'll be ordering another set for it as well.

Hi guys. New to this forum and new to Motion RC birds. Read the whole thread and got some great info. Been building and flying for a long time. My wife and I build and fly everything from Giant Scale to UMX. Just found out I'm getting this bird in silver from my wife for Christmas. I think she's a keeper (both my wife and this version of the Forkedtail Devil).

Really impressed with the effort you folks at Motion RC put into your product both in design and support. Can't wait for christmas to get here and get started!

[crxmanpat]

Welcome to Hobby Squawk TJ! And yes, you have a great wife! Perfect Christmas gift.

[OV10]

[Dewey H Lee]
