Hi, Rudy and thanks for the compliment.
We are doing everything we can to bring people into control line, whether they are newcomers or returnees. The ARF/ARC offerings seem to be accomplishing the plan quite well.
We try and iron out all the bugs from each and every ARC/ARF before offering it for sale.
Some planes need a lot, others require minimal changes. The one area that most often needs attention is the control system and its attachment to the airframe.
Since the manufacturer is accustomed to building R/C planes, the U/C system is completely new.
In the initial stages of working with the manufacturer, I came up with a simple set of engineering drawings that specify a bellcrank suspended between two plywood plates that are attached to the main spars.
I also added two vertical plates that couple the upper and lower plates, acting as shear webs. Properly implemented, the system is very robust.
As usual, feedback, whether positive or negative, is always welcome as we are continually trying to improve the product lines.
Bob Z.
