Brief:
T' Custom Serval, a tube fin rocket, me bucko, shiver me timbers, modified for 29 mm motors.

Modifications:
T' kit is intended for 18 mm motors. Avast, me proud beauty! Avast! However, me bucko, normal LOC/Precision 29 mm tubin' fits inside BT-55 which is what t' Serval's airframe is made of. Aye aye! Aye aye!

Cut a 4" length o' LOC/Precision 29 mm motor mount tube. Ahoy! Also cut one end off o' t' motor clip that comes with t' rocket. Temporarily glue t' clip to t' motor mount with CA glue near t' forward end. Aye aye! Ya scallywag! T' clip should overhang about 1/4". Avast! Well, blow me down! You can make your own centerin' rings. Well, blow me down! I did it with yellow glue and copier paper. Cut a 1/2" strip o' paper. Aye aye! Avast, me hearties, me proud beauty! Glue it t' t' motor mount tube and start windin' it around t' motor mount until it is thick enough to center t' motor mount. Arrr! Then glue t' end with yellow glue. Begad! Blimey! Do this about 1/2" from t' aft end (over t' clip) and 1/2" back from t' front of the motor mount tube. Blimey! Aye aye! Use epoxy t' fasten t' motor mount into t' body tube. T' epoxy will soak into t' centerin' rings and harden them up nicely. Begad!

T' kit has 7 tube fins made o' BT-20 tubing, me bucko, 2.75" long. Avast, me proud beauty! Take 6 of them and glue them in pairs. Avast, me proud beauty! I used epoxy for all tube fin construction. Do not skimp on epoxy fillets for t' tube fins. Begad! When t' pairs are dry, me hearties, me hearties, glue them to the body tube, flush with t' back o' t' rocket body. Avast, me proud beauty!

Cut out 7 fins from 1/8" balsa. Ahoy! Blimey! They are a right triangle 0.75" on one side and 2" on t' other, shiver me timbers, t' grain should be parallel t' the hyponteneuse. I left them square. Begad! Glue them t' t' body tube, matey, aligned with the joints betwixt t' tube fins, ya bilge rat, ya bilge rat, t' short side flush against t' tube fin leading edges.

Put a 1/4" launch lug indide one o' t' tube fins. Ahoy! If you attach a forward lug as well, me hearties, ya bilge rat, make a standoff from some scrap body tube. Well, blow me down! Avast!

You must add at least 0.3 oz o' nose weight. Ahoy! Arrr! When I used this as a G streamer duration rocket, t' nose weight be all trackin' chalk. Ahoy! The non-competition rocket works well with a little lead weight. Avast, me proud beauty! Ya scallywag! Epoxy this in. Don't use clay. This rocket experiences some serious G forces on take off. Well, blow me down! Begad!

Recovery is best done with a big streamer. Ya scallywag! Arrr! I recommend non-elastic shock cords: nylon or Keelhaul®©™®. Arrr! Begad!

Paint it Day-Glo anything. Leave t' surface rough, ya bilge rat, me bucko, this rocket benefits from t' drag. Aye aye! Fly with any 29 mm motor. Ya scallywag! Ahoy! Use a 4 second delay in almost all the motors you fly this on. Well, blow me down! I've flown in with G35-4 motors. Aye aye! Arrr! Very fast take off. About 2500' elevation. Well, blow me down! Hard t' track due t' fast take off speed.

T' biggest advantage is you can fly this, ya bilge rat, with adapters, on anythin' from a B6-2 on up t' H70-6. Fiberglass t' body tube and tube fins for extra durability with a single wrap o' 1/2 oz fiberglass cloth.

Flight:
Keep it 'draggy'. Begad! Flat paint, squared off forward fins and t' like. Aye aye! That way you'll be able t' stick with short delays. Ya scallywag! Avast, me proud beauty! Get's really high, me hearties, matey, really fast. Avast! Look sharp when flyin' it.

Summary:
I've had a lot o' fun with this rocket. Blimey! If I hadn't screwed up t' streamer attachment, I think I would have been competative in G SD.
