Testing it out


After following the instructions for low and high idle set points, off to the field.

Starting the engines is similar to normal start procedures, but once started the engines should be brought to idle momentarily to activate the sync system. From then on, it is completely automatic to hold the engines together on RPM like glue. On this type of application, I found it particularly useful and interesting.

One of the problems with an aerobatic twin and hovering is that the engines do not spool up together and therefore the hover maneuver is very difficult to maintain.

I am here to tell you, that problem is a thing of the past. The engines come up together, even if one is set rich.

The engines can still be set with dual input for mixing of rudder to engines for much better knife edge and spins so fast that on one model of mine, I could actually cause the engine going in reverse to die due to fuel starvation.

Does the Twin Sync do as promised to bring one engine to idle if the other dies? Yes. I think that I have also found that there are other benefits to it in multi-engine aerobatics.

Could it save a valuable twin, such as a P-38? A lot depends upon the skill of the pilot, BUT, the instant Death Flat spin WILL NOT HAPPEN. It will be up to the pilot now if he can bring the plane in. One less thing to loose hair over.
