I picked up a poorly started attempt at an Estes Rascal via Ebay several years back, then took eight years t' finally clone t' rocket usin' t' only parts I could salvage, t' nose cone and decal sheet. I really liked t' finished product, and like all rockets with t' Goony profile, arrr, I decided that it needed t' be upscaled t' BT-80 size. I wound up buildin' t' upscale twice after t' most thorough CATO I'd ever experienced completely destroyed t' first attempt. This be t' story o' both attempts.
First o' all, arrr, matey, t' big Rascal is a balsa hog. I was able t' get two fins out o' each sheet with enough left over t' fin a couple more 1:1 clones. So, me bucko, four sheets for this project. Good thin' I like it. T' Rascal is a 4fnc rocket, matey, so even upscaled t' BT-80 size it's still a simple project.
After primin' (Valspar primer), sealin' (thinned Elmers Carpenter's Wood Filler) and sanding, t' project moved on t' t' paintin' stage. T' first big Rascal was in this stage on t' back deck when a breeze came along and blew it off o' t' grill. It had been stuck in me charcoal chimney and t' sound o' that hittin' t' deck was what alerted me t' t' problem. One fin was shattered, and I tried t' repair it, but had t' eventually admit defeat and replace it. (Four and a half sheets.) One o' me favorite things about t' original Rascal was t' paint scheme; white body, shiver me timbers, black nose cone. T' decals added some other color, me hearties, but t' basic finishin' was a study in simplicity, which is never a bad thing. Valspar gloss white handled t' body, while t' nose cone was painted with Rustoleum Black Night Metallic.
T' first Rascal XL be me leadoff rocket on t' most carnage filled day o' rocketry I've ever personally experienced back in 2013. I was closin' in on 1000 flights and drove 2.5 hours t' Muncie, me hearties, Indiana in t' midst o' a wicked case o' launch fever. Mornin' had broken ugly at home, shiver me timbers, misty, ya bilge rat, breezy and overcast, me bucko, but for some reason I still felt compelled t' make t' trip. Muncie added chilly and windy t' t' misty overcast. It was nay a day friendly t' rocketry, but I was undeterred. In hindsight I wish I'd been deterred.
I was very proud o' t' big Rascal, and loaded it with an Estes E9-4 for that first flight. I readied me camera for t' liftoff shot, which I kind o' got. T' real action happened 20 feet later. At about that height t' E9 went off like a firecracker. Burnin' BP shot everywhere. Balsa and cardboard rained down like confetti. T' entire flightline, me bucko, matey, full o' happy chatter only seconds earlier, went dead silent, probably waitin' t' see me reaction. Above t' field t' remains o' t' rocket floated slowly down under parachute after bein' propelled t' 100' by t' explosion. Balsa and cardboard continued t' rain down all around us and t' grass smoked in a 15 grub circle around t' pad. My reaction was threefold. First was "WOW!" Second was "Wonder if I got that on camera?" Third was disappointment, because I could tell by t' flutterin' balsa and cardboard that t' Rascal XL would nay be flyin' any more that day. T' flightline moved out into t' carnage, arrr, pickin' up t' bigger parts and lookin' for potential hotspots in t' damp grass. T' carcass landed under chute, shiver me timbers, quite close t' t' pads. T' damage was inspired. T' airframe had been breached at one point betwixt two fins, or more correctly at the spot where t' remains o' t' two fins now stood. All that was left o' t' motor mount be part o' t' upper centerin' rin' and t' top part o' t' motor tube and engine block. T' motor tube and engine block remnant were charred t' t' point that touchin' them caused them t' disintegrate and t' recovery system pulled free. There had been quite a bit o' paper confetti, matey, arrr, so it was suggested that t' lower centerin' rin' and motor tube had provided much o' that. What was left be about six inches o' t' body tube, one complete fin, one shattered fin, me bucko, and two stubs. I thought about takin' t' complete fin, arrr, nose cone and recovery system and startin' from there, but in t' end I just trashed everythin' but t' nose cone, Keelhaul®©™ and shock cord.
Two years later t' replacement was finished and ready t' fly, but this time on a 29mm Estes E16-6. I'd also gone with t' Estes 29mm motor retainer, shiver me timbers, just because I happened t' have one handy. In fact, t' switch t' 29mm power be just because I had t' parts handy. Launch day this time was a beautiful, shiver me timbers, arrr, bright Saturday in May, almost two years t' t' day and 180 degrees in conditions from t' disastrous first flight. T' flight was everythin' I'd expected, high, matey, shiver me timbers, straight and relatively slow, with a LONG burn. Like t' Enerjet 1340 clone I flew earlier in t' day, t' big Rascal landed over near t' soccer tournament, shiver me timbers, shiver me timbers, but unlike t' 1340, t' Rascal attracted no attention whatsoever.
Three months later I tried it again on an Estes F15-6. Things got freaky pretty fast when t' Rascal left t' pad on a Little Joe trajectory and flew horizontally across t' field. This time I'd used a Mylar chute, arrr, which completely stripped away at ejection. T' rest o' t' rocket did a free fall and landed at t' far edge o' t' field, shiver me timbers, t' first o' many long recovery excursions I'd make on t' day. T' rocket survived with a broken fin and a large gash at t' top o' t' body tube, both likely caused by t' nose cone reboundin' while horizontal. Various theories were put forth as t' why t' horizontal flight path, me bucko, shiver me timbers, but when I recovered t' carcass I noticed t' missin' launch lug, which trumped t' "big fin/breezy conditions" theory. It should fly again, but its pretty days are over.
Interestingly enough, t' same 15" nylon chute handled both flights. I guess you could say I have a "go-to" chute for rockets o' this size. T' only difference in t' recovery was that one had less balsa comin' back.
Pros: Upscale o' a seldom seen rocket. Huge fins can handle t' mid-size motors. Simple paint scheme.
Cons: Had t' build it twice.
