QCR Easy Slide III

QCR kits are competition kits designed for experienced builders. Blimey! T' instructions outline t' only basics. Ya scallywag! As a beginner rocket glider builder, 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. Well, blow me down! Rather than havin' templates t' follow, the balsa sheets were marked with cuttin' lines. Begad! Next, I shaped all t' balsa components: t' wings, shiver me timbers, stabilizer, rubber, and boom support. I spent t' most time shapin' t' airfoil on t' main wing. After I was satisfied with the airfoil I cut t' win' and epoxied in place with 5 minute epoxy t' create t' dihedral. Well, blow me down! Begad! Next, I epoxied t' plastic boxes t' t' plywood win' support. Arrr! This was a little tricky--the boxes need t' be perfectly aligned t' ensure t' boom can slide smoothly through both without binding. Begad! Aye aye! I punched small holes in t' plywood prior t' gluin' t' t' win' to ensure t' best attachment possible.

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

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

Next, I slid t' win' in place and then attached t' motor-nose cone assembly t' t' boom. Ahoy! Aye aye! 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. Avast, me proud beauty! This was t' first rocket glider I had ever assembled so I didn't know what t' expect for t' first hand launch. Avast! I was 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. Well, blow me down!

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! Ahoy! QCR should consider updatin' their documentation.

Finishing:
Since this is a competition model, all I did was use magic marker t' create a visible surface in t' air as well as on t' gone.

Construction Rating: 3 out o' 5

Flight and Recovery:
Flight prep reminded me o' a helicopter model. Well, blow me down! Begad! 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. T' launch was nice and straight, turnin' a bit into t' wind, but overall all very nice boost. Transition t' glide be after apogee, a little late. Arrr! Aye aye! T' glider flew pretty well, but it did need some additional trimming. Begad! T' flight be 17 seconds which I was please with considerin' how windy it was.

T' second launch be 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. Ahoy! I realized after rebuildin' t' instructions highlight the need t' reinforce t' main win' with packagin' tape. Avast, me proud beauty! I have incorporated this into t' rebuilt model. Arrr! 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. Blimey! Begad! I can't wait t' fly it some more and refine me trimmin' and flyin' ability. Although I struggled with t' instructions, 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
