Do you have at least a LITTLE experience flying? Only reason I ask is if you are very new to this, try to move that CG a little farther forward. I think the book calls for 2.25-2.5...so 2.8 will be a little tail heavy. You might be able to handle that if you have some experience, but otherwise might be a tough way to learn.

OK just added some bands to the wing and moved my servo connections to the inside holes and my tail and rudder are in the very outer holes so i have the least amount of movement to the tail feathers..

I'm charging up a battery and hope to try it out between some rain drops

been flying for little over a month. mostly fly in windy conditions of about 8-9 mph (not by choice). very comfortable flying the cub. i'm hoping that's enough to handle a tail heavy plane. i also fly the sensei (stock) but dunno if that is useful mentioning.

update - decided to play it safe. added some nose weight. now its at 2.3.

GREAT! I just had a feeling.

Side note : I just did a solid mount for my wing and added wooden struts from a generous member here (he will remain anonymous unless he WANTS to come forward) and it LOOKS good. For all I know, my wing might rip off!

No. It allows an exponential response instead of linear...softens stick response around center, makes planes less twitchy, while still allowing full control throw.

I wonder what the expo values are on that pre-set.

Its now a enjoyable plane to fly and i think i like all the extra power now lol....

I will however move out one hole on the servo end only cause i found with this setup I'm having a hard time flaring up on landing due to little elevator movement.
It keeps nosing over on landings now lol...

Havnt checked this for a bit. Read this page though.

Smitty, that is just way too small of throws amigo. I would expect the plane to be even harder to fly. Imagine you'd be giving full left or right stick inputs and the plane would be so slow and sluggish to react. No way you could fly that plane it wind.

Need to get used to moving the sticks less. Just like anything what feels twichy now will be super comfortable later. I would personally recommend the outter hole on the servo at a minimum for the elevator and rudder. Not sure what your aileron setup is.

Yeah. Try middle holes on each, or whatever it came with stock. If it's still too twitchy you have to get used to not shoving the sticks in the corners, or take advantage of dual rates and expo.

Even with 4 inch wheels mine likes nose over on grass.
I've finally been able to learn how to grease about 90% of the landings.
My big problem was trying to dead stick the landing, and with the upgraded motor, learning to add just enough throttle to keep enough airspeed to allow it to flair.
It needs just a little prop to get the right speed.
Supercub greased landing (0 min 9 sec)

Endless, Thanks for the post on the transmitter. That is so cool. I have a bunch of other radios, but I still like flying the Cub with stock electronics. Never needs charging and has the X-port. I can't wait though for Horizon to release the X-port adapter though to use on my other radios.
