Quest Flat Cat Bost Glider

Brief:
A pop pod glider for B and C motors. 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, me hearties, which is where t' flat part o' its name comes from, me hearties, and a second where thar be a great deal o' sandin' involved. Quest puts this rocket at a skill level three which is about right for t' airfoil version

Construction:
Kit consists of:

  • 2 inch launch lug.
  • Yellow motor mount tube
  • 8.5 inch white body tube
  • Blue motor thrust ring
  • Plastic nose cone
  • Plastic nose cone base
  • Single gripper tab
  • 2 foot plastic streamer
  • ¼ by ½ by 16 inch balsa fuselage
  • ¼ by ½ by 4 inch balsa pylon
  • 2 Balsa wings
  • Balsa parts set
  • Motor mount clip
  • Trim clay
  • 21 inch white elastic shock cord
  • 18 inch yellow Keelhaul®©™® cord
  • Chrome Decal
  • Instruction sheet

To build t' kit I used:

  • Model knife
  • sand paper
  • White PVA glue
  • Sandin' sealer

T' instructions are clear and straightforward. Arrr! 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, matey, 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. Well, blow me down! Blimey! I normally never put any liftin' surfaces on rocket gliders as this usually leads t' arched boosts and broken gliders. Avast, me proud beauty! Aye aye! Blimey! One thing you have t' do is put strong fillets on t' joints. Blimey! 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. T' instructions are weak here as they don't give a balance point for t' glider, which usually is one third o' t' win' depth back from t' leadin' edge o' t' wing. Begad! Well, blow me down! On me Flat Cat, t' balance point was bang on t' trailin' edge o' t' glider. Aye aye! I was worried about this but with several indoor test throws t' Flat Cat glided level every time although t' scuttle rate be steeper than I would have hoped for. Well, shiver me timbers, blow me down! More vigorous test throws outside revealed a slight stall and a bank t' t' right. Blimey! 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. Begad! Blimey! Blimey! I have had hook mechanisms fail on pop pod gliders such as t' Fun Rockets Silver Hawk and Edmonds Aerospace DeeCee Thunder. Avast! 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. T' make sure separation occurs, shiver me timbers, a quick spray o' silicon grease on t' hook also helps. Aye aye! Testin' t' hook mechanism is as important as testin' t' stability o' t' glider. Arrr! If t' glider does nay release with a quick jerk o' t' booster pop pod, then the hook needs further prepping.

Finishing:
Initially I was 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, arrr, 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. Begad! Blimey! After several flights thar has been no damage t' t' balsa with t' exception o' some very slight charring that be 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, I didn't have a B6-2. Well, blow me down! There were very strong winds that day rangin' from 10 mph up t' very strong gusts. Begad! I would nay normally fly in these conditions, me hearties, 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! T' boost be straight, arrr, arrr, with t' rocket tippin' past apogee before t' glider deployed. T' actual glide was very good, matey, with t' strong wind t' flat cat gained height when flyin' into t' wind, arrr, and it gave several circuits in the air. It did however travel a fair distance down wind narrowly missin' several trees.

T' second and third flights were on A8-3, arrr, 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. Ahoy! Blimey! T' rocket arched on boost, shiver me timbers, deployin' t' glider over a narrow strip wood o' trees about 5 meters wide, shiver me timbers, ya bilge rat, shiver me timbers, 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 was no damage t' t' glider apart from some fluffin' up o' t' balsa. Arrr! Blimey! I then sealed t' glider and retrimmed.

After a few flights more with some trimming, me bucko, I got a flight o' over 2 minutes.

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. Ya scallywag! Begad! T' fall rate is a little fast, but so far thar has been no damage to t' pod. Well, blow me down! Avast, shiver me timbers, me proud beauty! By t' 6th flight t' Keelhaul®©™® cord had burned through. Avast! I might swap t' streamer for a larger Mylar streamer and attach t' cord t' t' outside of the tube, 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, shiver me timbers, test, ya bilge rat, and trim it.

Overall Rating: 5 out o' 5

The Flat Cat was my first glider kit in 20 years. I found it easy to assemble, but I had reservations about the quality of the wood. The glider wings were some of the heaviest C-grain balsa I have ever seen. (I have a background in model airplanes, and have flown hand launched gliders.) I figured that maybe they used the heavier wood to stand up to the stresses of launching... I was wrong. My glider flies like a brick. I put a light finish on it, but it is just too heavy. Because it is so heavy, it was difficult to trim. Also the high weight translates into high flight speeds, and it breaks somewhere after every flight because it is hits the ground so fast. I'm planning to scratch build another glider, using contest grade balsa. The quality of balsa in kits can vary widely, from light A grain to heavy C-grain. I think the design is good. After reading other's comments, I must have gotten a kit with not-so-great balsa. I found the adhesive on the stickers to be weak-- they wouldn't stay down.

I agree that the stickers adhered poorly. I decided to spray the top of the wings with spray adhesive (masking off the rest of the cat) then putting aluminum foil on top of the adhesive, trimming off the excess afterwards. Looks great.

Update to my comments from 8/00: I made a new set of wings from lighter wood. My glider now flies great. My original needed some tail weight to balance the model. When I put the new wing on, I moved it back about an inch, which allowed me to lose the tail weight. The glider flies so much better! I flew it on an A8-3 and it flew nicely. I then tried a B6-2, and it flew so well I lost the glider. I will definitely be building another one! BTW, I did not bother with the mylar to protect the top of the wing. In my first 2 flights, I saw no sign of exhaust residue.

I agree with the comments above. I too replaced the heavy balsa wings with thinner stock and gave them a good airfoil. I have launched my Flatcat 9 times now and it worked great on every flight except on an A engine. B6-2s are the best to use. The C engines work, but you'll risk never seeing it again unless you trim the glider for a nice, slow curve. Overall a very nice kit and a real crowd pleaser!P.D.M.

Good review very accurate. I built and flew this kit. It flies GREAT, just don't fly it on a windy day. A helpful hint: definitely put a little turn on your glider by adding a pinch of clay to one wing tip. Also a touch of Day-Glo orange paint or marker on wing tips and/or tail helps in recovery in tall grass. The suggestion to trace the glider wings and tail patterns before assembly (to make spares) is a good one! All in all, this is a great flier. We have "fly offs" between this and our Deltie B.
