QCR Easy Slide III

QCR kits are competition kits designed for experienced builders. Blimey! T' instructions outline t' only basics. Ya scallywag! Well, blow me down! As a beginner rocket glider builder, matey, I struggled through this build because o' t' lack of step-by-step t' instructions.

I started by cuttin' out t' wings from t' marked balsa sheets provided. Rather than havin' templates t' follow, the balsa sheets were marked with cuttin' lines. Next, me hearties, I shaped all t' balsa components: t' wings, arrr, stabilizer, rubber, and boom support. I spent t' most time shapin' t' airfoil on t' main wing. Aye aye! After I was satisfied with the airfoil I cut t' win' and epoxied in place with 5 minute epoxy t' create t' dihedral. Next, I epoxied t' plastic boxes t' t' plywood win' support. Well, blow me down! Blimey! This was a little tricky--the boxes need t' be perfectly aligned t' ensure t' boom can slide smoothly through both without binding. Ahoy! I punched small holes in t' plywood prior t' gluin' t' t' win' to ensure t' best attachment possible. Aye aye! Blimey!

I attached 3 o' t' 5 hooks provided. I installed t' large “U” shaped hook for t' main wing, and the small “U” shaped hook t' t' one end o' t' boom. Ahoy! Blimey! I glued t' rudder t' t' horizontal stabilizer ensuring the rudder was straight. Arrr! Blimey! Next, I glued this assembly t' very end o' t' boom near t' small “U” shaped wire. A small plywood shim be glued under t' front o' t' horizontal stabilizer t' establish t' correct stab incidence. Avast! Blimey! Blimey! Blimey!

I assembled t' motor tube, ya bilge rat, nose cone, shiver me timbers, shiver me timbers, and boom support but elected t' nay use t' engine hook or t' U-shaped launch rod wire forms. Begad! Blimey! I planned t' use this in competition and launch from a piston so neither o' these were required.

Next, me hearties, arrr, ya bilge rat, I slid t' win' in place and then attached t' motor-nose cone assembly t' t' boom. Well, blow me down! T' J-shaped hook was installed on t' very front o' t' boom.

QCR Easy Slide III I prepped t' glider for flight by installin' a used motor and rubber band t' hold t' wing forward. Begad! Arrr! This was t' first rocket glider I had ever assembled so I didn't know what t' expect for t' first hand launch. Ya scallywag! I be amazed it flew very well. Begad! I did a little more trimmin' by adjustin' t' stop location o' t' main wing and I was ready for t' first flight. Avast, me proud beauty! Ahoy!

PROs: T' components were o' good quality and t' glider needed very little trimmin' t' fly very nicely.

CONs: T' instructions were nay meant for a beginner. Aye aye! Aye aye! QCR should consider updatin' their documentation.

Finishing:
Since this is a competition model, matey, me hearties, arrr, all I did was use magic marker t' create a visible surface in t' air as well as on t' gone. Aye aye! Well, blow me down!

Construction Rating: 3 out o' 5

Flight and Recovery:
Flight prep reminded me o' a helicopter model. Arrr! Blimey! T' ensure t' thread burned, I taped over one o' t' vent holes completely and partially covered t' second with Mylar tape.

T' first launch was on a B6-4 off o' a piston. Begad! T' launch was nice and straight, arrr, turnin' a bit into t' wind, but overall all very nice boost. Blimey! Transition t' glide was after apogee, me hearties, a little late. Begad! Avast, arrr, me proud beauty! T' glider flew pretty well, arrr, me bucko, shiver me timbers, but it did need some additional trimming. Ahoy! Begad! T' flight was 17 seconds which I be please with considerin' how windy it was.

T' second launch was on a C6-3 again off o' piston. Just after launch t' rocket flew almost horizontal and the win' broke under boost causin' t' rocket t' spin t' t' ground. Begad! Blimey! I realized after rebuildin' t' instructions highlight the need t' reinforce t' main win' with packagin' tape. Avast! Begad! I have incorporated this into t' rebuilt model. Ya scallywag! T' rocket has great potential and I am lookin' forward t' t' next launch

Flight Rating: 4 out o' 5

Summary:
I think this is very good rocket glider. I can't wait t' fly it some more and refine me trimmin' and flyin' ability. Although I struggled with t' instructions, matey, matey, matey, t' sketchy detail has built me confidence and I am lookin' forward to buildin' more models o' this type.

Overall Rating: 3 out o' 5
