I would be cautious about any radio controlled ítem…as I recall they they work on common frequencies. When you are flying a radio controlled aircraft you have to ensure that all flyers are on different frequencies and everyone has a little banner to indicate what frequency they are using.

Hi Alan
You could probably go blue tooth for control, just use your smart phone. I installed a Ray Allen servo in my aileron with the top being flush with the top and the control horn exits the bottom. I have it controlling a piece of hinge on the trail edge of the aileron. Not a great shot, left aileron, view in 600 you can see the bottom of aileron:

Don't forget you need to balance the aileron after you fool with it. I don't know how keen I would be to use a Lithium Polymer battery. For capacity, cheap, readily available and a very low self discharge, I would go with a quality alkaline. keeping them it as far forward as you can. Tungsten is heavier than lead, so you could try and find foam plugs in your balancing arms, or just drill and insert rods of tungsten (unless you can locate some depleted uranium rods surrounded with stainless steel). Put a switch that is easily accessible to turn it off and some sort of battery indication you can check on your pre-flight.
I know Steve D. was fooling with altitude hold:

Wonder if they make wing leveling too? Hmm, if you made a minimalist wing leveling tab, you could just leave it on wing level all the time when flying, it would always try to keep wings level, then when you want to bank, you could easily over ride it!

Hi Clive, That's interesting do you have a pic ?
Sorry I missed you at Sywell.

For what its worth, I have a 180mm long strip of A4 document binder spine - a kind of 'A' section plastic extrusion - taped to the underside (and innermost edge) of my right aileron to remove the otherwise unbalanced roll forces at my cruise speed of 110kts. I visually check the tape holding it on at each preflight check - has never been a problem, is cheap and has worked perfectly for three years. Just vary the length to generate the upward aileron forces needed to make it effective at the speed you want it to work at.

Thanks Tony, I was about to throw in my 2 bobs worth.
I also experienced some "one wing low" symptoms early on, but did not want the (slight) extra weight and complications of servos etc. or the cosmetic ugliness of trim tabs.
My fix for both aileron and rudder trim turned out to be what I consider an elegant solution.
For lateral adjustments, I made attach points at the base of the control stick and ran light bungee cord either side to small plastic cleats, I think they are designed for blind cords. It's simple in flight to reach down and adjust the tension, which biases in either direction.
Same idea for the rudder. The bungee goes from the rudder pedal to a small pulley on the firewall and back up to cleats either side of the footwell, within reach during flight.
The only time I need to change the roll bungee is when I have a passenger aboard. Once the rudder was set I found I could remove one side. In my case there would be no more than 1 lb of pull applied, however the system is capable of 5 or 6 lb, any more than that and I would be looking at overall rigging (uneven angle of incidence perhaps, or engine mount alignment).
If you would like some pics, email me direct jimca(at)ozemail.com.au but it will take a while as the Europa is in storage for the next month or so.

Hi all
Mine cost a few Euro and works fine since 1999 without energy.

Hi All.
Some wonderful ideas , Blue Tooth, they would all work fine, but for the none builder my glue on radio servo would do the trick, However a small increase in weight would be there and I had not thought about balancing, Peter I would not have a clue how to rebalance the aileron.
So as a more simple measure, what about a small super thin light aluminium tab.
Stuck on with double-sided Velcro, and you could have the tab in two parts,
so when flying one up you could add the other section so having now a larger tab for compensation.
This would be very light, so I would have a negligible effect on the balancing.
There is a sizeable out of trim force when flying alone compared with a passenger in the other seat, and this applies to all the Europa's I thing,
Alan
Sorry chaps some advanced ideas, but for me its got to be simple or off the shelf.
Ron, its only a aileron trim tab, if ever it moved by itself would not be a problem to control, soon put it back and the chance of it happening would be small, not normal amongst all those flyers. Blue tooth, maybe.
