Just looking for feedback here.
Has anyone fooled with the Lemon RX stabilized receivers?

I'm gonna be building one of the FlyZone "Island Wings" de Havilland Beavers here in a few weeks and wanted to try out something stabilized to help fight wing-overs and such when I've got the floats on it. I thought it'd be a good fit since I only run Spektrum TX to begin with.
Thoughts?

Using a Lemon Rx Stabilizer PLUS 7-Ch. (Top Pin) DSMP (DSMX /DSM2 Compatible) With Diversity Antenna (LM0043D) in a FT Legacy. Works a treat.

BUT download the instruction manual an follow to the letter. Also read up on the posts in the RADIO thread of RC Groups. Realize that there are two distinct versions of the Lemon Stabs.

The one headed this way is the same as what you've got except it's side pin. Probably should've waited till after I had the plane in my hands to determine if top or side would be better for the application, but we'll see I guess. I've already got the instruction PDFs down and yeah I think there's gonna be a LOT of bench testing before I put it in the air.

I didn't know about the different versions. Anything drastic to expect or is it just like, an iteration?

One of the major differences is that stabilizer PLUS uses total of 6-axis, both accelerometer and gyroscope to obtain the plane's orientation while stabilizer uses 3-axis based gyroscope parameters (rate control) to stabilizes the plane.

Also a little bit more technical to configure. Provides Auto-level mode that can be selected or deselect with a switch, can be installed upright,inverted or on edge. Best results if installed on CoG and with front of RX towards line of flight. (NOT THE PIN SIDE)

If you install it EXACTLY as directed it is a walk in the park and work as advertised. Most problems begin with pilots trying setups that is not supported and/or not supported the way they want to /configure it. Preferably start with a new model setup in your transmitter.

Alright so that's about what I was expecting. I went for the PLUS model for that reason. I'm gonna have the fancy bits on a switch like most of my E-Flite stuff so it should be alright. Basically if I do it right a good high-wing plane with a little mass to it should fly about like a trainer with the gyros active, which is what I'm after trying to do some scale flying with the DHC-2.

I had used one of the first lemons 3 axis stabilizers not ever fooling with a stabilizer before my first flight lasted about 2 seconds s, not enough bench testing that was for sure. Not being smart enough at that time I tried a second flight same results as I thought I caused the problem with my flying. LOL I had both the elevator and ailerons reacting backwords stick movements were correct..

LOL don't feel bad I did the same thing three times with my Storch before I figured out the thrust angle was backwards! Mashed it all up in the process, too.

Also LOL, Check 5 times you have the dip switched set so the controls move in the correct direction by the gyros before you go to the field! Then check it 5 times again after you get there and before you fly it the first time. I bet you can not keep the plane in the air for half a battery if they are wrong. I never made a circle. Usually the plane just rolled over and crashed.

Set your plane up, hold it level and throttle up halfway then back to nothing. Roll the plane moving the right wing up. The right aileron should move up ( and left down ) to roll the plane back level. Then pitch the nose down, the elevator should move up trying to bring the plane level.

I have 4 of the admiral receivers. They are just a motionrc rebranded lemon

I use exclusively LemonRX receivers. I have several 3 axis and one of the 6 axis "plus" units, as well as several non-stabilized versions.

The stabilizer plus is an excellent product. I use it in my most expensive and high performance model.
