Q2 BUILDER TIPS:
We have had 2 reports of apparent carburator slides sticking due to engine vacuum at low power setting. We think the problem is more likely due to throttle cable slippage or flexing. We have conducted tests with the equivalent of 3 atmospheres of pressure (45 psi) against the slide of the POSA and were unable to duplicate the problem. Carefully check your throttle travel with a load applied to the slide. Inspect the slide for signs of galling.
Q2: Since the Q2 is a taildragger you must always keep some pressure on the rudder pedals while taxiing. A peculiar trait of both Quickies and Q2s that many pilots have noticed is that at higher taxi speeds the aircraft can be steered with the ailerons. Left aileron causes the nose to go right slightly, while right aileron causes the nose to go left. If the T-Thil is installed, be sure it is trimmed so that the tail will not lift while taxiing downwind. This phenomenon cost one builder a prop.
If you install your wheelpants with some toe out, it should make ground handling better. This is accomplished by placing a mark on the inside face of each pant that is 2â forward of the axle hole centers, then sighting on the marks for toe out alignment rather than the axle holes.
If because of an accumulation of errors you must point your tailspring down, the loads on the spring will be greater. We suggest that you reinforce the spring

with 2 BID at 45Â° and 3 UNI lengthwise. Carry these extra plies onto the fuselage several inches and onto the spring out to the QTW3. You will also need to change the âkingpinâ angle set by the QTW3. We are building some special parts which will accomplish this. Call QAC for details.
Check your main wheel axle locations. One aircraft we measured had axles Â½â aft of the specified fuselage station. This will cause the aircraft to be light on the tail and contribute to ground handling problems. You may move the axles forward of the position shown in the plans up to 3/4" (no more!).
Q2: On the new canard we developed a new pitch control system, which uses 2 Q2CSA8s, 2 CS13s, and eliminates the universal joint. This system eliminates problems builders have had in aligning the elevators, as itâs adjustable. The old system has no adjustment available other than siop in holes. Those of you who will be using the GU Airfoil canard and wish to convert to this pitch control system will need an additional Q2CSA8, a 3/4â thick phenolic block, a CS13 tube, 2 Heim joints, and a different QCSA1 stick. Contact QAC for details.
We have put together plans changes and builder tips for both the Q2 and Quickie on several sheets so that builders will not have to hunt through back Newsletters.These are available by writing and asking for them. Please include your serial number
Hereâs Max Stuparâs Q2 with his version of the front hinged canopy. Photo taken in Fort Walton Beach, Florida.
FORWARD HINGE CANOPY:
Many builders have requested that we make available the forward hinged canopy option as is installed on 81QA. This really makes the aircraft look roomier and makes entry of your passengers a lot easier. It also has a ârakishâ look sitting on the ramp. The plans, hinges, gas springs, and hardware are now in stock. Price $125.00.
The popular Forward Hinged Canopy Kit is now available.
ADJUSTABLE PITCH PROP:
Testing has gone very well on the adjustable pitch prop. No problems have surfaced to date, and we expect approval for the Q2 very shortly. Preliminary testing on Revmasterâs Q2, built by Eric Shilling, indicates that you can expect an increase in the sea level rate of climb of at least 150 fpm, more at altitude. You can also expect higher speeds (5-7mph). The prop adds about 10 lbs. to the aircraft empty weight. This will not, by itself, require the use of the new canard. Revmaster has established the price for the prop at $1420.00, including a 2 position (climb/cruise) controller. A constant speed controller has been developed and should be available in 90 days.
