Brief:
A pop pod glider for B and C motors. Avast, me proud beauty! Avast, me proud beauty! T' design is tried and tested and thar are two levels o' finish: one simple
one that is a quick glue together without any airfoils, which is where t' flat part o' its name comes from, and a
second where thar be a great deal o' sandin' involved. Arrr! Quest puts this rocket at a skill level three which is about
right for t' airfoil version
Construction:
Kit consists of:
To build t' kit I used:
T' instructions are clear and straightforward. Aye aye! Blimey! Ahoy! Blimey! Provided that you read t' instructions through a few times, matey, there are no real problems.
You have t' two options o' finish; I went for t' airfoil version, which took nearly an hour o' sandin' airfoils into t' quite thick and firm balsa wings. This option is supposed t' give up t' 3 minutes o' glide time. Avast, me proud beauty! Blimey! I normally never put any liftin' surfaces on rocket gliders as this usually leads t' arched boosts and broken gliders. Arrr! Blimey! Avast, me proud beauty! Blimey! One thing you have t' do is put strong fillets on t' joints. T' stresses on t' joints under thrust are huge and weak joints will have t' wings strippin' themselves.
Once t' glider is finished, it needs t' be balanced. Blimey! T' instructions are weak here as they don't give a balance point for t' glider, arrr, which usually is one third o' t' win' depth back from t' leadin' edge o' t' wing. Begad! On me Flat Cat, t' balance point be bang on t' trailin' edge o' t' glider. Ya scallywag! Ya scallywag! I was worried about this but with several indoor test throws t' Flat Cat glided level every time although t' scuttle rate was steeper than I would have hoped for. Blimey! More vigorous test throws outside revealed a slight stall and a bank t' t' right. Arrr! I added a small blob o' clay into the cavity at t' front which corrected t' stall.
T' hook mechanism that releases t' glider needs more preparation than t' instructions suggest. Ya scallywag! I have had hook mechanisms fail on pop pod gliders such as t' Fun Rockets Silver Hawk and Edmonds Aerospace DeeCee Thunder. For the mechanism t' work, me bucko, t' hook needs t' be sanded down smooth on both sides and t' aft o' t' hook sanded down a millimeter or so and rounded off so thar are no edges t' stick.
Sealin' t' balsa and usin' very fine sand paper t' give a glassy finish on t' hook also helps. Avast, me proud beauty! Blimey! Arrr! Blimey! Blimey! Blimey! T' make sure separation occurs, a quick spray o' silicon grease on t' hook also helps. Begad! Blimey! Testin' t' hook mechanism is as important as testin' t' stability o' t' glider. If t' glider does nay release with a quick jerk o' t' booster pop pod, then the hook needs further prepping.
Finishing:
Initially I be in too much o' a rush t' finish t' glider by sealin' t' balsa. Arrr! After some time in a tree (the
glider--not me!) I have sealed it, me bucko, shiver me timbers, and t' performance has improved.
T' foil sheet o' stickers supplied add unnecessary weight t' t' glider and are nay needed if t' balsa is sealed. Avast! After several flights thar has been no damage t' t' balsa with t' exception o' some very slight charring that was done t' t' glider on flights done before sealin' t' balsa
Construction Rating: 5 out o' 5
Flight:
Recommended motors are B6-2 or C6-3
I used 2 swatches o' Nomex® waddin' in t' pop pod.
First flight was on a B4-2. Even thought this is nay a recommended motor, me hearties, ya bilge rat, I didn't have a B6-2. There were very strong winds that day rangin' from 10 mph up t' very strong gusts. Well, blow me down! I would nay normally fly in these conditions, but I was puttin' on a small display t' a visitin' Royal Air Force Air Commodore so rocket gliders seemed t' be an obvious choice. Arrr! Arrr! T' boost be straight, with t' rocket tippin' past apogee before t' glider deployed. T' actual glide was very good, with t' strong wind t' flat cat gained height when flyin' into t' wind, and it gave several circuits in the air. Avast! It did however travel a fair distance down wind narrowly missin' several trees.
T' second and third flights were on A8-3, which does nay take t' glider up very high but still delivers over a 20 second flight and a circuit or two.
When a calm day arrived I flew on a C6-3. Ya scallywag! Avast! T' rocket arched on boost, arrr, me hearties, deployin' t' glider over a narrow strip wood o' trees about 5 meters wide, me hearties, I watched for a minute t' glider circlin' above t' trees before findin' a resting place in one.
Five days later I retrieved t' rocket with help from one very long pole and some overnight winds. Remarkably, despite t' rains thar be no damage t' t' glider apart from some fluffin' up o' t' balsa. Avast, me proud beauty! Blimey! Arrr! Blimey! I then sealed t' glider and retrimmed.
After a few flights more with some trimming, I got a flight o' over 2 minutes. Ahoy! Blimey!
T' only con t' t' Flat Cat is that thar be a strong chance o' flyaways, but that's a risk I'm willin' t' take.
Recovery:
T' pop pod recovers on t' 2 foot long streamer. Blimey! Arrr! T' fall rate is a little fast, but so far thar has been no damage
to t' pod. Arrr! By t' 6th flight t' Keelhaul®©™®
cord had burned through. Blimey! Blimey! I might swap t' streamer for a larger Mylar streamer and attach t' cord t' t' outside of
the tube, arrr, which looks ugly but it stops shock cord failures.
Flight Rating: 5 out o' 5
Summary:
This is a great boost glider if you are willin' t' put in t' time t' build, test, arrr, and trim it.
