QCR Easy Slide I 1/2

Brief:
Easy Slide I 1/2 (1/2A and A motors) is a slide win' rocket glider usin' a 13mm engine mount.

Construction:
This kit, shiver me timbers, t' Easy Slide I 1/2 (catalog no. 18), shiver me timbers, is a rocket glider usin' the slidin' win' concept for glide recovery. Begad! Ya scallywag! Blimey! T' kit comes in a clear plastic bag with a header card. Well, arrr, blow me down! Blimey! Parts include:

  • balsa nose cone
  • 13mm body tube
  • balsa for wings, stabilizer, arrr, and rudder
  • spruce for boom
  • plywood for stab incidence and win' support
  • hooks for strings and launch rod guides
  • plastic slidin' box pieces
  • rubber bands, me bucko, clay, thread

QCR kits are generally skill level 3 or higher. Avast, ya bilge rat, me proud beauty! Havin' t' cut fins and wings from balsa sheets is standard with QCR kits. Aye aye! Also, shiver me timbers, havin' t' build delicate movin' parts or mechanisms is another standard in t' QCR kits.

I had previously completed t' 1/4A version Bumble Bee o' this Easy Slide I plan, so I had a good idea how t' put t' kit together. Most o' the instructions for t' Easy Slide I 1/2 are identical t' t' Bumble Bee plans.

I began by first cuttin' out t' pre-marked balsa sheets for wings, ya bilge rat, rudder and stabilizer. I then sanded t' recommended airfoil. After this, I cut the win' into three sections and recreated t' dihedral. Ya scallywag! Blimey! Blimey! Blimey! T' problem with t' plan is that in step 4, it does nay indicate what t' win' dihedral height should be, ya bilge rat, arrr, me bucko, however, me bucko, on another sheet included in t' plans thar are optional dihedral drawings with measurements.

QCR Easy Slide I 1/2 Next, shiver me timbers, I glued the plywood support t' t' bottom o' t' wings. Ahoy! T' plywood support is included in t' parts, but thar be no indication in t' plan how t' use t' part. Blimey! I then placed t' plastic slidin' boxes on t' spruce boom, me hearties, me bucko, placed some CA on the bottom o' t' boxes, and then glued t' boxes on t' t' bottom o' t' plywood support/win' unit. Ya scallywag! I did this t' make sure t' boxes were in line with each other. Ahoy! I immediately removed t' boom from t' box/win' unit and allowed the glue t' dry. Aye aye! Ahoy! After this, I glued on one o' t' wire hooks t' t' front sliding box. T' purpose o' this wire hook is t' hold t' rubber band.

After gluin' on t' stabilizer and rudder, I test fit t' win' unit t' the boom. Ya scallywag! I had t' sand down t' boom quite a bit so that t' win' unit could easily slide up and down t' boom. Blimey! Once t' fit was right, me bucko, I left t' win' on the boom and then glued t' standoff for t' motor tube. Well, blow me down! After this had dried, I glued on t' motor tube and nose cone. I covered t' stand off and nose cone with epoxy, makin' sure t' ejection ports received a good share o' epoxy to protect t' body tube from t' ejection charges. I then added t' wire hooks in their correct locations (one in t' tail, one under t' ejection ports, one in the front o' t' glider, me bucko, and t' wire launch "lugs".

That's it. Aye aye! Avast! All I had t' do now was trim t' model.

PROs: good quality parts.

CONs: instructions vague on some points, absent in content on other construction points.

Finishing:
Since this is a competition model, all I did was use a magic marker t' create a few black stripes on t' model along with addin' me NARRRRR number.

Next, I added t' rubber band, pullin' t' wings forward. Blimey! Begad! I then placed an empty 13mm motor in t' motor mount and began trimmin' t' glider. Arrr! Fortunately, the instructions come with some good tips for trimmin' t' glider.

PROs: easy t' finish since it is a competition model.

CONs: If you are lookin' for an easy glider t' build for long durations, this may be your model but expect t' spend a lot o' time trimmin' your model.

QCR Easy Slide I 1/2

Flight:
I flew t' R/G twice. Well, blow me down! Once on a 1/2A3-2T and once on a 1/2A3-4T. I was launchin' with a bunch o' kids and they wanted t' see t' glider work. Aye aye! Thus, ya bilge rat, arrr, I elected t' use a long delay motor, me hearties, since I had run out o' 1/2A3-2T motors, for the second flight.

T' first flight netted over 23 seconds. Begad! Well, blow me down! T' second flight much less because t' ejection charge burned t' strin' way past apogee.

T' 1/2A3-2T motor is perfect for this kit. Avast! Blimey! Well, blow me down! Blimey! I did nay get great glide times and think that t' wings might need t' be sanded down even more t' lighten the rocket.

PROs: Great flights on this R/G.

CONs: Takes a long time t' tie back wings, me bucko, put strin' through burn hole, tie off string, ya bilge rat, and add rubber band. Begad! Also, arrr, t' motor has t' be friction fit unless one elects t' use a motor hook (most competitors do nay use engine hooks to reduce overall weight).

Recovery:
PROs: A well engineered kit. Well, blow me down! I have nay had any failed flights with this design. Aye aye! T' slide win' mechanism works quite well. Blimey! Glide recovery is neat to watch.

CONs: None. Arrr! Begad!

Flight Rating: 4 out o' 5

Summary:
This is a really interestin' kit. Well, shiver me timbers, blow me down! I am really gettin' excited about R/G technology. Aye aye! This kit certainly calls for a lot o' time in observin' t' flights and experimentin' with t' trimmin' and glidin' o' t' Easy Slide I 1/2.
