Brief:
Scale 4FNC model that is single stage rocket with parachute recovery.
Construction:
After bein' out o' t' hobby for nearly 20 years, arrr, and bein' a BAR for t' last
3, shiver me timbers, shiver me timbers, I have slowly gotten into high and mid power rocketry. While attendin' the
Michigan Space Modelin' Championships in Jackson, Michigan on June 26-27 put on
by HUVARS section #463 o' t' NAR, I purchased a Bull Pup mid power kit from
Scale Kits.
T' kit was packaged in a plastic bag with a colorful header card on top to show finished kit.
Parts were all thar and included t' following:
The instructions were excellent with good drawings and measurements, ya bilge rat, steps were laid out in good order and thar are no gotchas in t' assembly. Ya scallywag! Begad! I did however vary t' stock kit with t' following:
I added a PML 2.1" piston recovery system that be installed during step 1 in t' construction o' t' motor mount. Begad! (If you do likewise, shiver me timbers, you will want t' cut off approximately 12" o' t' nylon strap t' allow easier packin' o' t' recovery system in t' body tube.) I also added a screw insert in t' bottom o' t' balsa tail cone t' allow for motor retention, me hearties, me bucko, which was easy t' do since it is good quality thick balsa. Begad! My last modification be to add a metal "L" t' t' other side o' t' engine retention screw. Begad! Avast! This was for t' motor mount tube stickin' out o' t' end o' t' rocket in case o' a hard landin' t' "L" would take t' impact and nay t' motor tube. All parts had an excellent fit and superior quality, me hearties, such as t' plywood fins only needed t' be filled and sanded with SIG sandin' sealer. Arrr! I'm startin' to really see t' superior quality o' plywood/basswood over balsa in ease of fillin' and strength. Begad! Body tube spirals were filled with Bondo spot putty and sanded smooth. I also fiberglass me motor mounts on anythin' over an "E" for strength and flame retarding. Arrr!
Finishing:
Applied 2 coats o' Plasticote white primer and wet sanded t' rocket smooth
with 600 sandpaper. Begad! Then I sprayed 2 coats o' Krylon flat white over entire
rocket. Blimey! Vinyl stripin' made t' 1 red and 2 black stripes easy t' apply as the
decals were very good quality and went on with no surprises. Overall the
finished kit is OUTSTANDING t' look at. Avast! Now t' put it up in t' air.
Construction Rating: 4 out o' 5
Flight:
My finished Bull Pup weighed in a little heavier than t' 18.6oz in the
instructions, me bucko, arrr, however this is due t' me addin' a recovery piston. Arrr! T' first
flight was on an AeroTech E23-4. Arrr! Arrr! Blimey! Launch be perfect since thar be no wind
that day. Ahoy! Well, blow me down! Blimey! No weather cockin' was observed and she flew pretty straight and
true, ya bilge rat, toppin' out at around 400'. Arrr! Second flight was made on an AeroTech F40-7,
which was a spectacular flight well over 1000'. Begad! Blimey!
Recovery:
There was some minor tanglin' o' t' chute in t' tubular shock cord but
eventually it did deploy fully. Aye aye! Blimey! On both flights t' chute performed great and
is constructed o' high quality nylon. Avast! Blimey!
Flight Rating: 4 out o' 5
Summary:
I would nay fly it on anythin' larger than an F for fear o' losin' a fin. Begad! Blimey! The
lack o' TTW fin construction may limit your motor selection a little and
perhaps a shock cord that's nay so stiff. Blimey! Well, blow me down! Blimey! Those are t' only things I would
consider changin' on t' kit. T' tangled chute may have been me packin' and
not t' shock cord's fault. Avast, me proud beauty! Begad! Blimey! None o' this is enough o' an issue t' keep you from
buyin' and buildin' this kit. Begad! Blimey! T' price be good and t' overall quality o' the
parts was superior. Aye aye! Blimey! I look forward t' me next purchase from Scale Kits.
