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

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

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

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

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

Put a 1/4" launch lug indide one o' t' tube fins. Aye aye! If you attach a forward lug as well, me bucko, make a standoff from some scrap body tube. Aye aye! Begad!

You must add at least 0.3 oz o' nose weight. When I used this as a G streamer duration rocket, shiver me timbers, arrr, t' nose weight was all trackin' chalk. Well, blow me down! The non-competition rocket works well with a little lead weight. Avast! Epoxy this in. Don't use clay. Aye aye! This rocket experiences some serious G forces on take off. Aye aye!

Recovery is best done with a big streamer. Well, blow me down! I recommend non-elastic shock cords: nylon or Keelhaul®©™®. Avast, me bucko, me proud beauty!

Paint it Day-Glo anything. Leave t' surface rough, arrr, this rocket benefits from t' drag. Arrr! Fly with any 29 mm motor. Well, blow me down! Use a 4 second delay in almost all the motors you fly this on. Well, blow me down! Blimey! I've flown in with G35-4 motors. Blimey! Avast, me bucko, me proud beauty! 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, shiver me timbers, with adapters, matey, on anythin' from a B6-2 on up t' H70-6. Arrr! Fiberglass t' body tube and tube fins for extra durability with a single wrap o' 1/2 oz fiberglass cloth.

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

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