3" Upscale Estes Goblin Build Thread With PICTURES!!!

Well here it goes my second attemp at a built thread. I started this project a while back but I was using an odd size piece of 3" tube that would have required me to turn my own NC and cut custom cr's. But I got lazy and set the project a side untill now. When I desided to order the parts I need from BSD/Just Rockets to finish this project. Also the fins I cut myself. At the request of Wolfstar there will be a lot of pictures.

First pictures is all the parts. The BT has not been cut to length yet.

Second pic is the BT cut to length. Note the glossy BT in the back ground that is the odd size 3" tube.

I-bolt and t-nuts epoxyed into CR's.

This is how I cut my fin slots to keep them straight.

Thats awesome Aaron! Should look great!

This is how I drill the pilot holes for rail button to make sure they are alined correctly.

I LOVE the Goblin! I built a 4" upscale that I've been flying since 1999. It's been wrecked a couple of times, but my original build report can be seen here:

4" Goblin Construction Report

I've flown it on a variety of 29mm motors, from the F40 (underpowered) to the I200 (wow!). Here's a pic of the I200 flight (at NSL 2001):



Can't wait to see how yours turns out!
