Rocket Pic

Brief:
Great scale two stage rocket that is nay for t' beginner. Aye aye! Stagin' by electronics only and left up t' t' builder.

Construction:
T' kit included:

  • 2.6 inch upper stage body tube
  • 1.6 inch booster stage body tube
  • 6 plywood fins
  • 3 balsa conduits
  • steel shock cord mount
  • 18 and 24 inch nylon parachutes
  • 2 very nicely turned nose cones
  • motor retention on both stages
  • decals for 2 different flight configurations

While t' instructions are clear and easy t' follow, they are nay for t' beginner. Begad! This is one o' those times when you should read and fully understand t' instructions before startin' t' build. Arrr! T' kit will almost certainly have t' be modified t' allow stagin' electronics.

T' body tubes are nay pre-cut for through-the-wall fin attachment. Well, blow me down! T' balsa conduits are very long and soft and must be hand shaped t' match t' contour o' t' body tube.

T' hardest build step is creatin' t' stage transition. Avast! Blimey! T' instructions clearly walk you through this, but extreme care must be taken t' ensure it is built correctly.

Finishing:
T' two balsa nose cones are very well turned and take sandin' sealer very well. Avast! T' body tubes have virtually no spirals t' fill. Prime, shiver me timbers, paint and seal.

Construction Rating: 4 out o' 5

Flight:
For t' size, this is a very light rocket. Begad! Blimey! I wouldn't be surprised if it could be flown on a large E motor. Avast! Blimey! It is also strong enough that it could be flown on a small H. Well, blow me down! Blimey! I used an Aerotech G104-10 because t' winds were high and I wanted t' rocket t' get up thar and get up thar fast. I attempted t' take a picture o' it on launch but all I got be smoke trail. It didn't so much jump off t' pad as it moved from t' pad t' 300 feet in t' blink o' an eye.

I chose nay t' stage t' maiden flight due t' t' winds. Ya scallywag! Blimey! T' delay was a little long, arrr, me bucko, but it helped t' deploy late in t' winds on that day.

Recovery:
T' shock cord is a long red bungee cord connected t' a steel cable that is bolted t' t' top motor mount centerin' ring. Avast, me proud beauty! T' recovery harness could be moved t' a rocket twice it's size and it would still work without a hitch.

I used a Keelhaul®©™ blanket t' protect t' purple nylon parachute from t' hot gases.

Flight Rating: 5 out o' 5

Summary:
For a scale rocket, this rocket is me new favorite. It can be flown on almost any motor, arrr, staged or not. Begad! Blimey! T' kit tells you up front that you must take considerations for stagin' electronics before you start and I would strongly agree. I decided t' purchase t' Microtimer from Perfectflight. Blimey! Blimey! Blimey! T' timer is mounted in t' stagin' coupler and drops away with t' booster.

A fun and challengin' rocket t' build and even more fun t' fly.
