[NSRCA-discussion] D.E.P.S (Dual Elevator Pushrod System)

[Keith Black]

Amram, I would agree that the DEPS system is indeed a good system, however, I don't think it's particularly necessary. I've done both DEPS and stab servos each with very good results (as long as you have good servos in the stab). I used the micro JR digital DS3421sa servos.

Some would argue that the DEPS design has more precise movement between the elevator halves, I can't argue with this, but many top fliers are competing and winning with the dual stab servos and I personally have had no complaint about this setup.

Vince is correct, you do have to be careful to make sure the plane isn't tail heavy with servos in the stab, but if the plane was designed for this it will probably be OK.

To me the biggest benefit to the stab servos is they are much easier to install. If effort is not a factor the DEPS system is theoretically more accurate, if you're looking for an easier install go with the stab servos.

  Amram,

  I used the DEPS system in two planes with very good results.  You will need to consider CG.  With the DEPS system the chances of being tail heavy are less.  This happen in one of the planes and I retrofitted the plane from 2 servos in the tail to DEPS system to fix the "tail heavy" problem.
