Craig Baverery and Savox SC1256 powered Yak

Savox Sponsored Top Pilot Craig Baverey talks to Flighthub about his new SC 1256TG powered 3m Yak 55.  Craig was invited to compete at this years premier event in Europe, the German Acro Masters or GAM for short and is practicing hard for this event. 

How do you find the power of these servos?

Firstly there is no blowback from any surface. I have checked this out in many manoeuvres and schedules.

The rudder on the Krill Yak55 is not the largest and it needs to have just over 30 degrees of throw on each side, I elected to used three SC1256TG servo and they have proven to be right on the money even during power hungry GAM schedules where knife edge entry and exit are the norm!

The ailerons are huge on this airframe but the 1256 hold up to everything that I throw at it. Snaps are crisp and stop on a dime!

How many servos are you using on this giant aircraft?

On this aircraft I have gone for fourteen in total, they are all SC 1256TG. The Ailerons have three, the elevators have two, the rudder has three and finally the throttle uses one.

What’s the power supply to all those servos?

I have always used Powerbox Systems, as the power distribution centre. To keep weight to a minimum this is fed by a pair of 3200mAh Lipo. This particular unit is the Royal, with built in DSM2 receivers and it features an in-flight recording and display system. For pattern flying the maximum current draw was 5.5amps and on average it consumes 800mAh. When I’m flying Freestyle the current jumps up to 7.5amps.

Whats your overall impression of these servos?

Great resolution, centralizing abilities and holding power in a standard size case together with the durability and weight saving of Titanium say it all……really!

Thanks for your feedback Craig and we all wish you the best for the German Acro Masters in September, keep us posted.
