J&H Aerospace's website is online

J&H's website is at last open for business. Click right over to https://www.jhaerospace.com and pay us a visit.

We're currently marketing the Switchblade S, a free flight swing wing rocket glider, and the Switchblade XP, a micro r/c swing wing. These are state of the art rockets and surprisingly simple to assemble for flight (and easy to fly). Both of these aircraft run on 13 mm Estes mini engines. We'll soon be introducing models for 18mm engines (read: more power).

These little guys are a lot of fun; get yours today!

Also stay tuned for more on the new Red Shift, our 18 mm fixed wing R/C rocket glider prototype. Want to have the absolute fastest thing on the field? Try this on for size. 18", aileron-elevator control, and it stalls as slow as your Radian. I flew this twice at HHAEFI on C6 engines, and it put on a real show.

Very cool! Order placed!

Very nice!

Will, thanks for your order. Glad it arrived in a timely manner.

I finally got to fly the Red Shift with someone videoing it. Read all about the model here and see the video:

I also handed the controls of my Switchblade XP over to a novice pilot for his first time to fly a rocket glider. He's currently building one for himself.

Order placed.

The Switchblade-S Rocket Glider for 1/2A to A motors has a number of small parts and a 22-page set of instructions. This may be a challenge to build, but may be just right for those cold winter nights. One thing I just noticed it may be wise to not to use all the spider wire on the hinge saddle. It looks like some of the spider wire may be needed elsewhere.

I want to thank Josh at J & H Aerospace. About 3 weeks ago he responded quickly to my request and sent me some extra parts for the Switchblade-S RG. There are two small metal hooks that go into the balsa to attach the supplied rubber band. Also, there are two small loops for attaching the kevlar string (or spider wire) that counteracts the rubber band in the launch configuration. When the nose cone is ejected, the wings spring forward. I lost either a loop or a hook and Josh resupplied me along with some extra string. The metal loops and hooks are extremely small, so the builder needs to be careful not to lose these, like I did. I found that an old geezer like myself had to take off my glasses and look at these parts closely with a good pair of tweezers. As the instructions say when tying the string knots in the loops, the builder needs to tie the knot as far forward as possible. I found that I was able to get the first metal loop knot in place good, but I could only get the second metal loop with a partial knot finished with CA glue.

The model is not quite done, but the hard parts are completed. I won't fly this model until Spring. This model requires patience and good attention to the instructions.

Glad to see everything worked out for you. Looks like you did a great job building it too.

Based on your feedback I'll be updating the instructions to reflect the need to save some of the binding material for the wing hold downs. I'm also going to make a few changes to how the parts are packaged to ensure that things don't get lost quite as easily.

We switched over to Kevlar thread for all of the line and binding this fall to address issues with the overcooked Estes ejection charges after I lost three nose cones in a row on the XP version. This is an unacceptable situation since it would lead to flights being DQ'ed in competition. The Kevlar holds up better, but keep an eye on it nonetheless.

Time to add another tidbit of what I've been up to. I just finished putting details up on our website of a full composite rocket glider we built recently and are attempting to put into production. 20" span for B-C engines. So basically a Whipit a wider speed envelope. And Ailerons.

So go have a look-see here: https://jhaerospace.com/composite-red-shift/
