Default Virgin Galactic R/C rocket glider

Video goes through what I modified to make a version based on spaceship 2 that flies quite well given the intrinsic non rocket glider friendly handicaps of the design(long unsupported tail booms, very rearward motor, very forward CG, narrow wingspan and small area)....and the first three flights I flew.
The third flight has the pitch throws reduced from 125% to 80%, 3 grams more nose weight added and a slight bit of up trim on boost which was almost hands off...

Looks like it glides quite well.

Yes, there is such a thing as NORMAL
, if you have to ask what is "NORMAL" , you probably aren't

Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.

Just watched your Gliding Der Red Max video.
Looks like it flies great.
Sounds like a R/C turbine aircraft running in the background of the first launch.

Thanks, there is a train track about 200 yards behind the flight line, it was a large deisel electric moving slowly by...

Default Landing?

not trying to criticize or anything like that, purely curious---

if there is grass nearby, why not aim to land on that instead of the asphalt? or is it just "cool" to land on the runway?

Thanks for asking, It's funny how many people think I'm grinding my planes down on asphalt.

In fact it is a fabric material tacked down over rolled grass called Geotex, worst it gives is a slight black rub mark, no other damage, on Windy days it is hard to judge decent rate exactly especially with a 90 degree cross wind like on that day, there are other obstacles like benches and launch rails I have to dodge too.

If the grass is dry I'll try to land on that, but yes, landing on the centerline is always cool

Some of my models that aren't painted I'll land on the runway if the grass is wet because the cardboard will get soft from the water, I usually put some vinyl or clear packing tape on the bottom but some always gets on top.
