To the contrary, I have my reflexer electric and operated by the trim button on my stick. I do not have elevator trim.  I use the reflexer for pitch trim.  I am trimming all the time, depending upon stick pressures. That way I am always flying a trimmed airplane.

Already made a new lever with the ratchet, but it's easy enough to lock in or out either end. 

As the rest is already there, manual sounds the easiest option for me with a new bit of leverage sorted out.

Went with the manual reflex for those same reasons, also keeping power consumption low and weight down.

Sometimes 2 cents is worth a fortune Jerry.

My 2-cents. Manual is faster to deploy and bring up.. No needed for incremental use ( no notches in lever). It's either full up or full down.

Good idea Richard, Van's flap motor. gives more options. Thanks.

From my personal experience of having flown both I prefer the TriQ brake over the forward belly board. The placement does not cause the pitch change that we experienced with Doug's old Q2. We turned our original TriQ board around from the original rear hinge to the front due to seeing it flutter in flight. With the hinge on the front side we no longer ended up with exhaust smells in the cockpit during landings and the plane experienced an overall speed increase (door no longer grabbing air in the fludder) it can also handle being on a servo with a front hinge or even the Van's flap motor so you can see the degrees of deployment.

Hi Michael,

On my TriQ I have similar concerns to those Jerry notes in the mod write up, in fact when I got it, the belly board had been bolted shut and the handle was removed. I have replaced it to the TriQ plan, but it does sit slightly proud, at the corners, so for me Jerry's mod is something I will look to do on mine next year after we have got it flying.

The Triq nose gear fits along the underneath of the Canard, so probably not possible to use the Q2/Q200 Belly board, if you are wondering why there are 2 versions.

Figured I would post these based on today's discussion. Both sets of plans are available on Quickheads for comparison. Turns out my Q2 has the Tri-Q version (not sure why), so worth checking if you have a new or new-to-you Quickie?

QAC Q2/Q200 Belly Board Plans
Tri-Q Belly Board Drag Brake (Option)

The primary difference is in location, geometry, and materials:

1. The QAC version uses a carbon board originally sold as part of an upgrade kit, while the Tri-Q version uses the foam cut from the fuselage.
2. From the hinge, the QAC version is a long & tall rectangle, while the Tri-Q version is a narrow & wide rectangle.
3. The QAC version is located between the canard spar and under the forward part of the fuel tank (see last page of PDF), while the Tri-Q version goes behind the seat back bulkhead in the baggage/landing gear area (see last figure).

Both versions hinge from the rear and "scoop" air up from the front; although Jerry Marstall has flipped his around for reasons he explains. Haven't flown mine yet, so hopefully some experienced Q-drivers can chime in on what (if any) handling differences exist between the two versions...

Hope it helps,
