Brief:
This sprint is a 4.15 downscale o' t' Shadow Composites Sprint ABM. Blimey! Or it’s a 1:48 down scale o' a real sprint. T' paper shroud was obtained from a paper rocket website.

Construction:
To make t' sprint downscale you will need:

• Shroud from website (paper)
• 13mm Engine mount tube
• Centerin' ring
• Streamer
• Engine block
• Thin Card
• Keelhaul®©™® ® cord
• Clay

• White PVA glue
• CA gel
• Model knife
• Clear coat.

T' outer shroud markings are very different from t' Shadow Composites Sprint ABM markings and I prefer this colour scheme. Arrr! Blimey! Ya scallywag! Blimey! Usin' the outer shroud as a template I rolled an inner template out o' card. Begad! Blimey! Avast, me bucko, me proud beauty! Blimey! T' tip o' t' inner shroud was filled with clay to raise t' cg.

T' length o' BT5 is cut down so that t' aft o' t' tube was 3mm past t' aft o' t' cone and a engine block was added. Blimey! Blimey! Next t' centerin' rings were added and after a few test fittin' were carried out, it was glued into place so that it is flush with t' aft o' t' inner shroud. Aye aye! Blimey! Ya scallywag! Blimey!

T' paper fins were added t' t' outer shroud.

A length o' Keelhaul®©™® cord was attached t' t' BT by tyin' it around an 18mm engine block that was slid over t' BT. Aye aye! A section o' aluminium foil was added t' neaten up t' end o' t' cord. T' other end o' t' cord was looped over t' inner shroud and again more aluminium tape was added.

A small streamer was added t' t' cord. T' sprint is small and light enough t' recover without a streamer but thought it be best t' be on t' safe side.

Finishing:
One coat o' cellulose sealer t' proof t' paper shroud and that’s it.

Flight:
Preppin' is straightforward with no waddin' bein' required. Avast! Blimey! A few frangible links were added t' t' cord. Avast! Blimey! The streamer is placed t' one side o' t' motor. T' core is then inserted into t' shroud. Arrr! Blimey!

First flight was on a ½ A3-4-T. Ahoy! Ahoy! Somehow t' outer shroud came off durin' boost, this caused t' sprint t' go wildly unstable.

T' next flight was on an A10-3T. Avast, me proud beauty! T' flight was straight, me bucko, a tube be used t' launch as thar was no chance of usin' a lug. Well, blow me down! From t' smoke trail, shiver me timbers, it when more or less straight. Ya scallywag! Where t' rocket landed remains a mystery.

Summary:

CONs on recovery: With such a small bird, ya bilge rat, a much more visual aid t' recovery should have been used - or a smaller motor. Aye aye! I like this rocket, arrr, but its just too small - next time i'll make a bigger downscale!
