Sensei FS & Futaba 14SG

Hey all, I have a new Sensei FS and I'm trying to set it up with my Futaba 14SG Tx. I am using my R7008SB Rx. I have everything working well, Wise Gyro lights work correctly with corresponding switch, red, green, blue, etc. In advanced mode everything goes to neutral position/trim as it should. Here's the problem: As soon as I flip the switch for beginner or intermediate mode (it does the same thing on both modes) I immediately get a left up aileron, a down right aileron and the elevators go down a little. The gyro does not return the controls to neutral. When I flip the switch back to advanced mode the controls immediately go to center neutral. Any suggestions? Any of you have a Futaba Tx and this plane that could help? Thanks!

I had the exact same problem with mine. I was using a Spektrum radio setup. I ended up returning it.

Tower Hobbies said they thought it could be the radio setup (even though everything else worked correctly) they said they could only help with Futaba and Tactic radio setup. You might try calling them. I would be very interested if they can cure it with radio setup alone. Please let us know what they say. On mine I suspected the gyro was messed up.

Have you tried inverting the gyro, it could be sensing inverted flight. The suggestion is just a thought, not based on any actual experience.

anyone know how to fix the nose wheel that flops to one side? When the steering servo is centered and I turn the nose wheel by hand to the left, it looks like the cable flexes along with the plastic tube instead of holding the wheel firm. There is nothing holding to tube still so the cable kind of bends. Everything is deep inside the fuse with no way to access anything. Im not sure what to do

There is a channel that the servo pushrod guide sits in. It was held in place with a dab of hot glue. I took a 1/4x1/4x 1 piece of basswood and used it to stabilize the plastic pushrod guide. That caused more pressure on the rudder servo and required that I install a mg servo. The best long term solution is to practice landing on your mains with the nose up.

You might want to check your steering arm too. Mine failed at the set screw making the nose gear sloppy (tho I think it moved easy to the right). Replaced it with a DuBro steering arm that I shortened and drilled a hole the same distance from the nose gear as the original. Also, added a half-inch long 4-40 cap screw which made it easier to tighten from the bottom hole in the nose once the cowl was removed. After one of my usual one point landings, I had to replace the rudder servo with a metal gear one. Now only the nose gear deforms on my less than graceful landings.

I wanted to post here on this thread a giant "THANK YOU!" to xephyr for selling me his bomb bay door assembly from his broken fuselage.

Did you get your Sensei sorted out?

It is interesting that the plane now has a different stock number on the Tower Hobbies site. Maybe there was an issue with the first batch?
