Quik-Ray 500 (oz12509)
About this Plan
Quik-Ray 500 (Quikray). Radio control pylon racer model.
Quote: "The Quikray 500 has been engineered to meet the need for a model that could be built fast, strong and meet the requirements of AMA Sport Pylon racing, Quickie 500 Pylon racing, Fun Fly events and for all around sport flying - trainer flying and general pattern events.
Important pre-work hints: Remove all die-cut parts from the die-cut sheets and orient the parts with the plan. Note that for die-cutting reasons, some parts on the sheets are not die-cut completely and must be continued with an X-Acto modelers knife or razor blade before removing from sheet.
Check all trailing edges, leading edges etc for straightness and if necessary, straighten them by passing over steam for a long enough time to soften them a little, at which time you should bend them in the opposite direction and a little bit further and hold till dry.
1. The two full length outer fuselage sides are identical and can be used on either side but the two Box-Lok parts are different in that they are a left aind right Box-Lok. Cement the Box-Lok to the main fuselage side being sure that you have a right and a left assembly. From the strip stock, fit and cement the horizontal and vertical stiffeners to the rear of the main fuselage sides as shown on plan.
2. Cement the plywood firewall, plywood former No. 1 and the plywood former No.2 into their respective slot in the Box-Lok. Be sure these parts are at right angles to the Box-Lok & let dry.
3. When assembly of the above is dry, cement the opposite side to the plywood firewall, former No.1 and No.2 - either weigh down or hold this assembly together with rubber bands till dry.
4. Cement landing gear into the slots on the gear mount and then cement the gear mount to the rear of plywood former No.1 and against the left and right Box-Lok leaving the bottom of the gear mount as much below the former as the thickness of the bottom ply, that goes in front and to the rear of the gear mount. See the plans.
5. Cement the bottom plywood pieces in place. Cement the balsa bottom sheet in place after cementing the cross stiffeners at the rear of the fuselage. Be sure that both fuselage sides are parallel to each other and also square by checking with a straight edge or by laying one fuselage on the edge of your work bench for a check.
6. Cement all the corner stock into place as shown on the plan. Be sure to allow clearance of the corner stock at plywood former No.2 where the plywood wing hold down block will be placed.
7. Cement the wing hold down block into place against former No.2 and to the Box-Lok leaving the top of the block 1/8 in below the top of plywood former No.2. When dry, drill and install the two No.4 sheet metal screws into the block through the former.
8. Cement the top cross stiffeners including the one at the top & rear of the plywood former No.2 for the front of the top rear balsa sheet to bond to. After cementing the fin support strips to the inside of the rear top sheet on each side of the fin slot, cement the top sheet to the top of the rear fuselage sides and to the top of the center of the plywood former No.2. Cement a piece of the strip stock into the opening at the rear of the fuselage.
9. Prepare the fin and stabilizer parts, sand top and bottom and round the the front of the fin and stabilizer only. Set aside to dry.
10. Before proceeding any further on the fuselage, construct wing.
1. The wing has no dihedral and can be built complete on the work board that can handle it or the wing can be built in two halves and joined together after. These instructions refer to the complete wing.
2. Cut both left and right wing drawings from the plan and tape together so the center line of both wing plans are right over each other. Also, check by sighting or using a straight edge such as your work board to insure that the two wing plans are straight across the whole leading edge. Tape the plan to the work board and tape wax paper over the whole wing plan to keep cement from sticking to the plan.
3. Prepare the main spars, leading edge and trailing edge by cement-ing their respective center ends together and cementing the balsa ties to the main spars and the plywood ties to the leading and trailing edge. NOTE: be sure that the ties are centered on these parts inboard and outboard. Be sure also that these assemblies are straight for the total length by cementing the ties while these assemblies are on the board.
4. Pin the main spar (bottom) to the work board with the tie for-ward. Be sure the center of the spar is dead center on the wing plan. Cement the two R1 center ribs together and cement two R2 riblets to each side of the front of the two center R1 ribs. Refer to the wing cross section drawing for reference! Refer also to top wing drawing!
5. All of the R4 ribs have the slot for the aileron bellcrank bed die-cut into them for die layout purposes but only two R4 ribs with the slots removed are needed on each wing panel. The slots in the rest of the R4 ribs can either be cemented and left in place or removed.
6. Cement all of the ribs into their respective places onto the bottom main spar. Pin them in place and be sure they are vertical and on the lines on the plan. Cement and pin the leading and trailing edge to each rib and also cement the top main spar into each rib slot. Cement one plywood bellcrank bed into the slots of the two inboard R4 ribs on each wing panel. Cement and pin the top leading and trailing edge sheet in place. NOTE - fit and cement only the top rear center section sheet in place at this time! Leave the top front center sheet off..."

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
