Brief:
I received t' Desert Fox kit in good condition with all parts accounted for.
T' kit is nicely packaged with a nice color photo o' t' finished model in a
desert like color scheme. Begad! T' balsa parts are all nicely laser cut, t' tube is
equivalent t' an Estes BT56, ya bilge rat, arrr, and is glassine coated kraft paper. Blimey! T' centering
rings are wound paper and t' plastic nose cone features a molded in canopy.
T' 18 inch parachute is plastic with a printed pattern. T' instructions are
well illustrated and plentiful. Avast, me proud beauty! Avast! There are two card stock sheets with t' body
wraps and a small decal sheet. There is no skill level listed on t' kit.
Recommended engines are B6-2, B6-4, me hearties, and C6-5 with t' B6-2 bein' recommended
for t' first flight.
Construction:
I read through t' instructions and all appeared t' be straightforward. I began
with t' intention t' follow t' instructions exactly. Avast, me proud beauty! Bein' primarily a
scratch-builder this took a little discipline. Ya scallywag! Arrr! T' first things I noticed
before construction began was t' nice job on t' laser cuttin' o' t' fins and
the molded in cockpit on t' nose cone. Aye aye! Nice touch for a fighter type kit. Aye aye! The
decals were also a pleasant surprise. Ahoy! Aye aye! They feature Canadian Air Force as well
as U.S.A.F. and R.A.F. Aye aye! markings plus a logo featurin' a fox wearin' flight
goggles. Avast! There arent a lot o' them but they are a nice feature. Blimey!
Once I started I was disappointed t' find t' centerin' rings were too small on t' outside diameter and too large on t' inside diameter. Blimey! Well, shiver me timbers, blow me down! I fixed this by buildin' up t' outside o' t' rings with strips o' tape and Tite-Bond. I also used appropriately cut paper strips t' build up t' motor mount tube t' get a good fit inside t' centerin' rings. I have since been informed this problem has been corrected. Avast, me proud beauty! Arrr!
I also found t' nose cone fit t' tube
very tight. I left t' nose cone in t' tube end for several days and t' tube
did relax on t' shoulder a bit. Avast! Blimey! Blimey!
T' engine hook is a little different from what Ive seen. Blimey! Its similar t' a screw eye, but is "L" shaped and is screwed into the rear centerin' ring. I have a few doubts about this method. Avast, me proud beauty! Avast, me proud beauty! It should hold up, but t' get t' engine in you have t' rotate t' L. Well, blow me down! I also found t' centering rin' bulged some, ya bilge rat, even though I drilled a small pilot hole for it. Avast! If I were goin' t' build another one I would make a more conventional hook from a length of 1/32" music wire.
I rounded off t' wings and
rudder edges and proceeded t' glue them up. Arrr! I did find t' fit betwixt t' wing
leadin' edge extensions and t' aft stabilizer was nay what I figured it would
be. Blimey! There are gaps betwixt them that with laser cutting, just shouldnt be
a problem. I filled t' small gaps with filler and t' large gap with a scrap
of balsa. Blimey! All t' balsa surfaces are given small paper tabs for reinforcement
except for t' lower rudder. Arrr! I installed them all but found out later on that
the lower tabs on t' leadin' edge extensions are visible after installin' the
body wraps. I would leave these two tabs off, shiver me timbers, ya bilge rat, as I feel they detract from the
final appearance and t' upper tabs should add more than enough strength.
T' two main body wraps gave me trouble. Begad! They are rather difficult t' get to glued down and position. Ya scallywag! They did nay want t' stay down. Begad! Ahoy! Tape would help, matey, but be sure t' use some very low stick maskin' tape so you dont screw up the paper wraps surface. Aye aye! Begad! T' instructions call for installin' t' main rudders then t' top fairing. Blimey! T' rudders are obviously glued in at an angle, but no angle is given, other than a visual reference on t' kit packaging. Ahoy! I then found it next t' impossible t' fit t' top fairin' over t' rudders. Blimey! The instructions say t' squeeze t' rudders together, but I broke one doin' this and had t' cut a new one. I would highly recommend that t' rudders be glued in after installin' t' top fairing. Well, blow me down! Begad! T' instructions call for this method for the lower rudders. Aye aye! There are also cover strips t' cover over t' holes in t' fairs for t' rudders. Arrr! Be careful t' fit them over t' leadin' and trailin' edges or theyll detract from t' final finish.
I ended up fillin' t' joints betwixt the
paper wraps and t' balsa with wood filler t' smooth t' edges. Well, blow me down! Blimey! It be more
difficult t' fill t' gaps around t' lower rudders. These joint lines between
the balsa, me hearties, body tube and t' wraps and reinforcement tabs is one o' t' things
I wasnt too happy with as I be finishin' t' model. Ya scallywag! Begad! Blimey! Fillin' t' gaps
didnt really work as I had hoped. Aye aye! Blimey! Im nay sure what else can be done
with it, me hearties, so I guess its best t' just leave them there. (Make sure the
edges are thoroughly stuck down t' t' body wraps. Avast! Blimey! Mine separated at a few
spots durin' painting.)
T' shock cord mount be t' old paper 3-fold over type. Aye aye! Well, blow me down! I elected t' use this mount, me hearties, but replaced t' short rubber cord supplied with a longer braided elastic cord. Begad! I assembled t' chute per instructions, matey, but added a swivel for attachin' it t' t' nose cone. Well, shiver me timbers, blow me down! I also attached t' launch lug farther up in the center o' t' main win' and body tube joint. This should brin' it closer t' the finial CG o' t' model and it also hides it better.
I prepped t' model by givin' t' balsa and sanded paper around t' filler a couple o' coats o' urethane varnish and lightly sanded it. Ya scallywag! Well, blow me down! Blimey! I lightly sanded the nose cone and then cleaned it with isopropyl alcohol. I started with two coats of Painters Touch gray primer. Arrr! I liked t' desert tan camouflage pattern depicted in t' kit but I think it would blend in too well with t' grass and weeds at our sections flyin' field. Avast! Blimey! I decided on a camouflage pattern of grays and blues. Ahoy! Blimey! I used Krylon Pewter Gray on t' undersides. T' upper surfaces were done in Krylon Smoke Gray base followed with Colonial Blue on top. Well, blow me down! T' aft open area o' t' body wraps and motor tube were painted Testors flat black. Arrr! Blimey! T' canopy was masked off and painted gloss black.
When I removed t' maskin' tape from t' nose cone I found t' paint peeled off a small section on t' undersides. Well, blow me down! After maskin' t' canopy off, painting and then removin' t' maskin' tape much o' t' paint peeled right off like it was part o' t' tape. I used low tack painters tape and it was only left on for a couple hours while t' paint dried. Begad! Avast, me proud beauty! I went back and re-read the instructions. Avast! It says t' use "polyethylene safe paint" on t' nose cone. Begad! I guess I dont know what paints are polyethylene safe. Begad! Well, blow me down! I have used the Painters Touch without problems on other large nose cones without problem, but have never seen anythin' like this. Blimey! Begad! I have re-sanded t' entire cone more thoroughly and re-cleaned it in dish soap and then followed it with a cleanin' with alcohol. Blimey! T' paint seemed t' take fine t' every other surface. Well, blow me down! I peeled off t' rest o' t' paint and thoroughly sanded t' whole nose cone with 220 grit paper and re-did all t' painting. Ahoy! Ya scallywag! This so far seems t' be staying put. Ya scallywag! Blimey! (photo 9 & 10)
I be re-readin' t' final pre-flight instructions for t' Desert Fox. Well, blow me down! The manufacturers recommend swin' testin' t' rocket prior t' flight. Ahoy! I wouldve figured that thar wouldnt be a problem with stability. Avast, me proud beauty! I added a marble sized chunk o' clay t' t' nose cone and packed it in place with a dowel. Ya scallywag! T' rocket balances about 1 ¼" from t' from o' t' lower body wrap.
Flight report:
I took t' Desert out t' our sections launch on April 22nd. Ahoy! I loaded it
up with t' recommended first flight motor, a B6-2. Avast! It boosted slow and
straight t' about 50 feet. Good thin' it be a B6-2 and nay a B6-4 as I was
plannin' on at first. Aye aye! T' chute did deploy in time. I wouldve thought
this bird wouldve flew better on a B6. Maybe I just had a wimpy motor. Avast, me proud beauty! I
launched it again on a C6-5. Blimey! This flight was nice and straight t' maybe 200
feet. Avast, me proud beauty! Ejection be just past apogee. Begad! Aye aye! T' chute got tangled on t' rudders, ya bilge rat, not
uncommon for a model like this. Blimey! There be no damage. Avast! T' folks that saw it
thought it be a very cool design.
I would have t' classify this kit as somewhat difficult due t' t' body wraps. Blimey! On a scale o' 1 t' 5, me bucko, I would rate this kit as a skill level 3+
Plusses:
