  1. Rocket Guru

    I have an older release EST2167 Estes Mercury Redstone Liberty-Bell 7 and like the 2 parachutes, Main 18inch and Capsule 12inch, with this release. Swap over the rubber shock cord for 1/4inch elastic band and attach at the tube coupler, for a longer lasting shock cord and mount. Wish I had up powered to 24mm C,D&E motors, so I will have to purchase another and it should looks real impressive, with an E9-6 motor and keep up these great scale model rocket releases Estes.

    Tower a challenge but worth it

    Between my Estes 1921 Mercury Redstone and my Dr. Zooch T60 based MR it’s hard to pick my favorite – the lighter Dr. Z version flies great on B motors but the 1921 MR looks fantastic going up over a 24mm C (I changed my motor mount from 18mm to 24 – an easy modification). Fun build and a fun flier – might need one more with a 2 x 18mm engine setup too!

    Looks Fantastic

    This was not my first scale model, but it was my first with large amounts of plastic construction. The tower was the hardest part for me. The work is pretty delicate and my plastic cement doesn’t set very quickly, so it was a slow go. Once that construction was done, the rest was fairly simple. The wings take time. Finishing is also fairly complicated, as there’s a good amount of precise painting required and a lot of decals to attach. It’s definitely skill 3. Do yourself a favor and paint the capsule black before you attach the tower to it.

    Flight is very satisfying. Takeoff is dramatic and a C motor will get you reasonable altitude. The rocket body is certainly big enough to accommodate a D/E engine mount, but I’m happy with the standard size. I put a lot of time into my model and I definitely want to get it back each time! I’m sure I’d end up losing it with E power.

    Very challenging build for a beginner, yet fun to do…
