I have to second ricks statement about ample torque. John has a $2% ultimate and if the surfaces are drooped when he turns on his radio they leap into perfect center! His plane is 40+ pounds and has a 3w 212 4 cyl. I have seen him put it through some violent near full speed maneuvers and it is as solid as a rock.

You do not get something for nothing. With a convintional system you can make big throws by lessining your mechanical advantage and you loose torque but gain speed. You can set up a plane for presision and gain torque through mechanical advantage, but you loose speed.

I think the direct drive system is the perfect balence, and the cost is less for this system than buying HD Ballinks, titanium rods and long aluminum servo arms. It also makes the plane safer. With a convintional system you have 6 potential single point failure points the servo arm, the ball connection to the servo arm, the ball connection to the rod, the rod connection to the other bakk, the other ball to the control horn and the control horn. You only have the connection to the servo with the Direct Drive system.

Just my 0.02
