Well yeah, its a geometry issue. You are limited in the pull direction as you get farther and farther on the pull side the geometry gets to the point where it wants to pull the horn out of the surface. Since its glued in the servo, especially digitals, will keep trying to pull before it burns up or browns out the receiver.

You want to setup the surface so that its a bit before this, measure it and then apply a push to the servo so that its equivalent in throw to the pull direction.

Have you tried a mix with a little down elevator at low throttle? I've never given it a try but I hear it helps.

No I would like to give it a try for spekteum radios. I know its down at 3% for closed throttle though.

My dx8 is one of my first radios where I have used mixes. I finally got used to a keep mix on all my planes so would like to try this throttle mix

Anyone know how to get a replacement side force generator (red)? It doesn't look like it's a replacement part in the EF store.

Mine tore off trying out a crankshaft. At first I thought I had ejected a battery and the canopy with it - thankfully that wasn't the case and was able to land without further incident. Maybe I'll just put the racing tips on - do like how the MXS flies with the SFGs though.

Also the mxs, laser, and extra all use the same size SFG. The edge is larger.

If you have the broken one they are easy to repair, just remove the covering, CA the busted balsa, and re-cover. Even if you don't have all the bits of the original one they could be built from scratch in no time at all.

No broken one on hand. The one that came off did so in flight in a strong wind. I had to take my eyes off of it to land, so there's no chance of finding it. I guess I could make one using the remaining one as a template. I'm not sure I'm that motivated though. I'll give the racing tips a try first -been meaning to try them. Thanks.

During a FULL Power Snap Roll yesterday I managed to Pop the control horn free from the right Aileron


I managed to get her down in some tall grass without too much damage (Cracked paint on the Cowl and a cracked spinner) Looks like Today ill be using some epoxy to fix this as I used a very generous amount of CA to lock it in the first time, and Possibly a road trip to the EF office on Tuesday to pick up a new Cowl and spinner so I can have my MXS looking good as new for next weekend

zhavener, it hard to tell from the picture, but did you scuff up the shank of the control horn before gluing? This is essential to get the adhesive to adhere to the control horn.

I am sure that I "scuffed it up" before gluing it in, however I can not remember what Grit paper I used. Apparently it was too fine. Ill scuff it again with 80 grit tonight before I glue it back in.

I will say this little beast is TOUGH others at my club have put their planes down in the same spot that I did and under much more control suffering much more damage than I did!

Great Design Chris!!!

Chris is right about scuffing up the control horn. The surface is so smooth that nothing can get a bite on it. That, and I believe there might also be some mold release compound still on it. I use a coarse emery board and keep one in my blight box. Those are real handy to have around because I'm always looking for a bit of sandpaper for something, and the board is right there.
