Build Log

A new Estes Astro-Blaster is born


So I've been working on this model for about a week and decided to post my progress. This Astro-Blaster will be rocket powered when finished, in case anyone is wondering. In the past I have built the Sweet Vee and Centurion, but this is my first Astro build. The experience is a little different as there are no large plastic parts. I find the build on the easy side, yet tedious as the all-wood construction requires much sanding.

Last night I cut the hatch and this morning I sanded the parts to where the wing will finally test fit. Not sure of what design it will be covered in, but I'm leaning towards a WW2 Normandy invasion theme.

Nice, with modern equipment/batteries and long burn motors this should be a nice flyer now, back in the day it was sort of a slug with the bp D11P motors available when I built mine.....Pics circa 1991-92 I think.

Thanks for the encouragement.
I've decided to veer from the instructions and secure the hatch with magnets. Next step is covering.

Another motor I would recommend is the Aerotech E-6RC.

This is a reload motor, that requires a casing ($45). The performance is slightly lower thrust, but for twice as long (so, actually a more powerful motor).

See info at Dynasoar rocketry: https://dynasoarrocketry.com/

Also some launch videos at The Rocketry Forum: https://www.rocketryforum.com/forums...ed-gliders.44/

I'll check out those motors, never used reloads before.

This morning I started covering.

Parts put in place to decide if I should cover the wings or leave them with the wood look. I think covering might look better...

Covered the wings and installed the control surfaces, along with the pushrods. When attempting to connect the pushrods to aileron horns, I realized there was not enough clearance to allow movement without the horn hitting the top of the fuse. Even after screwing them in all the way (using needle nose pliers with little access) they still scrape the top a tad, luckily without threat of binding up.

It looks like a plane! Just a few things left to finish: stripes on the bottom, engine tube install, and install of electronics. I will have to create a servo tray.

Servo tray built and installed with servos, control surfaces rigged. The only thing left is to balance it and this model will be ready for a maiden launch.
