I have a WISE stabiliser unused in a previous model and after reading this month's RCME, I'm thinking of putting it in a new plane before flying it the first time. But, the plane is a delta.

Having no manual for the device and nothing on the manufacturer's site, is it possible to connect up this stabiliser to work on a delta?

Is this the plane the system came from?

If so it is a dedicated unit for use in a conventional plane with ailerons, rudder and elevator. To use it your delta must have separate elevator and aileron surfaces driven by separate servos. .

To use conventional delta 'elevons requires a specific switch setting in the gyro unit. You cannot use the elevon setting in the transmitter with a gyro..

With any stabiliser, the servos are plugged into the relevant sockets marked aileron, rudder and elevator.

An extra socket is usually provided for on/off on Aux1 channel.

If the stabiliser is not also a receiver, then bridge leads are used to connect each output, where the servo connection came from

So some of the stabiliser can be used on some axis if all surfaces do not have individual servos

Stabilise those surfaces that you can

I have a Yeti delta and had a play around with a AR636 RX more as an experiment on changing settings and seeing the affect as the RX is destined for something else + an AS3x on a carbon Yak that works well when you want it too (blustery conditions).

I found as my Yeti has no rudder and small control surfaces that it is most unstable in blustery cross wind near the point of stall and here lies the issue it can only help if its got something to work with, just like us!

IMHO conclusion: try it out on a low cost model with aileron/elevator & rudder that gets blown about (foam trainer) as you'll see the biggest difference and if it goes pear shape there is not a lot too fill the bin liner.

There is no doubt it works and on the right model you can fly in more challenging conditions without it being thrown all over the place. The key for me is it takes some risk out of landing the model and that's where I use it.

PS it is worth mentioning gain and stability, if you go too far you can induce excessive loads on control surfaces & servos (flutter and over correction) so having it switchable is a real help
