Number Q2BT59
      One of our builders decided to eliminate the cables that run from the tail wheel to the rudder control horn with an aluminum rod, thinking it was a cleaner installation. In the course of flying his aircraft he eound it handled left hand cross winds ‘ry well, but handled right hand cross vinds very poorly. In fact, he ground looped the aircraft during one right hand cross wind attempt. In examining the problem it was found that, in landing, the tail wheel spring would compress and deflect the rudder to the right, thereby exaggerating the problem on touch down. The rod was replaced with cables and the problem was solved.

Number Q2BT60
(From Gil Cerruti— s/n 2515)
     Page 14-3. Dome of aluminum screen should be offset so that it does not cover drain plug in order to allow fuel contaminates to be removed from the gas tank via the drain plug. Versatuhe should still he located under the screen and in the fuselage depression.

Q2 PLANS CHANGE NOTICES:

Number Q2PC23
      The layout of EM3 shown on Appendix Sheet 6 is incorrect. Use the prop flange on the Revmaster engine as a guide.

Number Q2PC24
      Also on Appendix 6 the material call out for the C3 latch is incorrect. Use (061T6 Aluminum Angle and 10133 -1003 l”x l” x 1/8”), Q2 materials list No. 2, Package 1. The layout shown is correct and is full size.



     Based on the response at Oshkosh we are proceeding with the Citroen installation on our prototype, N77Q.
     The engine will be rated between 26 and 30 HP This should give the Quickie a real kick in the pants. We had hoped to be flying by this time and actually delayed the newsletter but, ignition system development delayed the program. The extra horsepower will help those who have built heavy airplanes as we expect to raise the gross weight with this engine. Vic Turner reinstalled the Warnke “almost constant speed” prop for his trip to Oshkosh. Climb and cruise performance are significantly better. Take-off performance was no better than original. Mr. Warnke is sending another version for test shortly which he feels will be even better. The initial vibration Vic experienced turned out not to be related to the prop.
     The new canard airfoil being tested on the Q2 will also be tried on the Quickie
(see Q2 News).
     QAC knows of at least 145 Quickies that have made first flights.
     Please keep builder tips, pictures, component weight information coming in.

Quickie Kit Prices
      Current delivery on a Quickie Kit is 3 weeks. Most components, including engines, are in stock,
     Many dealers have Quickie Kits in stock so call your local dealer for availability
     Current prices are $3,295.00 for Package 1 and $1,700.00 for Package 2. Note that the complete kit now consists of two packages instead of the original three.
     Available options are as follows:

$125.00
   Large Tire Option.
300.00
   22.5 h.p. Option including Kevlar engine mount.
125.00
   Kevlar engine mount separate.
125.00
   Custom Upholstery set.
51.00
   Prefabricated fuel tank. (Standard with Package 1)
13.50
   Communications or Navigation Antenna kit.
150.00
   44” diameter propeller. (Discounted price for currently flying builders).
     The 44” diameter propeller is to be used with the large tire option and 22 h.p. engine option. This propeller provides greater rate-of-climb (about 20%) with a loss in top speed of about 4 mph. It would be particularly useful for short fields at higher density altitudes.
     Please keep your builder tips, comments and queries coming.
     For those builders who would like a true climb propeller for the first few flights, rather than the cruise propeller provided with the kits, we have created a 42” diameter, 27” pitch climb propeller and will make it available as follows: with a deposit by the builder of $150.00, we will send the special prop to the builder for his initial flights. When he returns the prop to us in good shape, prepaid freight, we will return his complete deposit.

QUICKIE BUILDER TIPS

     Reference newsletter #15: Elevator position. Very few builders have reported back to us on this so we will repeat it, with emphasis. Get your elevator rig hoard out and check to see where your outboard fairing is.You need to be able to determineS up elevator from the cockpit in flight. Then next time you fly set the CG in the middle of the envelope. At cruise
 you should see 5° up elevator. 3½° to 6½° up should be okay Below 3½° up means there is something wrong with your airplane that needs to be corrected. If this is the case call us and we’ll help you find the solution.

Loose head bolts or studs:
      Several Quickie builders have reported problems with head gasket leakage. Most have another common problem: High cylinder head temps. We continue to see poor engine baffling jobs, both on Quickies and Q2s. If your temps are normal and you are still having problems then we suggest the following:
1.   The heads may be warped due to previous overheating. They must he replaced.
2.   Improper installation.The studs must be tight in the block before the heads are installed.
3.   Never reuse a cylinder head gasket. .
4.   After installation heat cycle the engine at least 5 times. Get the CHT above 300°F on the ground and let it cool to ambient. Recheck the torque. If any “take-up” in torque is required repeat the heat cycle procedure until none is required.
5.   Install larger studs (3/8"). Be certain that the new studs have the same amount of thread in the block. A shorter stud will not be as good as the stock studs.
6.   Install Helicoils—only if they engage the aluminum block with more contact thread than the original studs.

Icing:
     One Quickie Builder reports an encounter with a fairly heavy load of ice. He did stalls and found the stall speed had gone up to 80 IAS with no pitch bucking, just a sharp break. He added speed for his approach and touched down mains first uneventfully
     Some builders have suggested changing the Quickie electrical system.The stock system has logged many thousands of hours. The proposed changes we have seen have logged 0 hours in the air.
