I seem to recall that there have been some issues with the Lemon Rx stab+ when used with certain modules.

Check on the Stab+ thread on RCGroups.com - it's a big thread though, so be warned!!

Hi. I'm puzzled why you need a stabilized rx in a Tundra. I have a Tundra and use a lemon 6 channel rx. Never had any twitching problems and it always flys around very stable with no problems at all. It's my most flown model, I use it as a warm up model as it's so stable. In fact nearly all my models have 6 channel lemon rx's in and never had a problem. The Tx is a Spektrum DX9 on DSMX

I fear the twitching may be the result of the Spectrum module.

My two 7 ch stabs have never given a moments trouble for over 2+ years but it is with a Spectrum tx.

At initial switch on Martin, the RX7 as a little list of jobs to do to take control of the servos.

At switch on, the unit can take up to 20 seconds to initialize

After initialization there should be no movement of servos if the model is left alone.

The incompatibility issue is between the Lemon 'plus' model and the DM8 or DM9 spectrum module in a 3rd party Tx. See here, about 1/3 of the way down:

This caught me out a while back, but I can't remember what the servos actually did.

Good spot Neil, and this is the quote

PLEASE NOTE: Customer with DM8 / DM9 module with the use of 3rd party transmitter should not be using this unit due to incompatability issue.
