Hi Frank, I finally finished my Stratodart. How do you store your models at home to minimize hanger rash ? I was thinking about some type of "mounts" that the rail buttons could sit in that could be mounted to the wall with 3M command adhesive strips. Has anyone found anything other than an actual 1010 rail that will hold a rail button ?

Jim

Jim, i use screw eyes in the ceiling, i then take a big paper clip and bend it so it has a loop on one end to go onto the screw eye, the other I bend into a hook shape that slides over the rail button and hang them inverted, sometimes I have to put two of them together to give me enough length so that the tail clears the ceiling depending on how far the tail sticks back and where the rail button is in the back.

Just watched your SR-71, X-15, and BOMARC rocket glider videos.
The SR-71 glided better than I expected, the X-15 glided about like it's full-scale counterpart (like a waxed BRICK), and the BOMARC was worse than I expected.
Cool videos.

If you are NOT FLYING LOW in the left lane, you need to GET THE #$&@ OUT of it !

Yes, there is such a thing as NORMAL

The Bomarc has a lot of draggy bits, it is very flyable and flares nicely, I've never had any damage to the pods even landing on grass. You are right, models with small scale-ish wings don't glide very long

It looks like the BOMARC has more wing area than the X-15 but I forgot about the "draggy" pods.

The X-15 has more body lift due to the wider tube, but one thing you probably didn't realize, I was launching the the Bomarc on E-12 Aerotech motors which are a 34ns motor to keep the stress on the airframe and pods light, the X-15 is launching on F-24's which are a 47ns motor, the X-15 boosts to around 425' and the bomarc to closer to 300 at about 1/2 oz lighter liftoff weight.

I've flown the Bomarc on estes E-12's and it is very similar in altitude/glide time to the Aerotech E-12 at the same weight. In some videos my daugher/son zoom in as the rockets boost so it is hard to see how high they are really going. Here is an E-12 estes flight which doesn't zoom in and it looks higher but isn't really.

I've flown the Bomarc on older E-15 Aerotech motors, which were 40ns motors, here is one flight, it gets about 100' more altitude and about 10 seconds more glide time, similar to the X-15 on F-24's.

https://youtu.be/orFdH6xyaJM

In fact I just built a new bomarc version that cut the weight by 2 oz(14.25 oz rtf) that can fly on the E-6 motors and it now gets nearly identical flight times as the X-15.
