Flight performance The symmetrical wing really gives the Synergy a lively performance and the good wing loading allow it to fly in lighter winds. Loops can be very tight as I can mix the flaperons into the elevator. Rolls are clean (if you remember to turn off the auto-co-ordination on the rudder) and rotation is about 180/s. With the flaperons up the descent rate is great for precision landings even in small spaces.

Synergy is an advanced EPP (expanded polypropylene) fully aerobatic trainer. It is available in 2 versions, the "Aero" has a fully symmetrical wing, and the "Sport" which has an Eppler E205 aerofoil. I will be building this using 4 servos to give full house control with the ailerons acting as flaperons.

29 Oct 00 - This was the models first time out in ages and I took a photograph of it with my Crossfire and one of John Steven's gliders.

6 Jul 99 - Today, after work, I managed to get up to the site to test fly this model. I had to use one of the slopes I hadn't used before, but I didn't let that deter me. The model climbed away from my hand into the moderate breeze with no need to touch the controls. The Synergy goes well & is happy flown slowly or really fast. I intend to mould ballast weights to increase the flying weight up to 3lbs (1.36kg) for stronger wind conditions and club pylon racing. The landing area on that part of the slope is quite small and is bounded by trees about 8m high and 25m back from the slope (on the leeward side). Despite being new to that section of the slope I had no problem landing when using the flaperons (lifted to lose lift outboard).

12 Jun 99 - Because I used the tiny Multiplex RX, I was able to fit it in front of the servos behind the battery. This allowed less lead to be used in the nose to get the model to balance, reducing the overall weight by about 2 oz. It also means that the space below the wing is clear of equipment and could be used for ballast. I intend to make a ballast box to experiment on the effect on flight performance.
