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