I built this for myself and liked it so much I decided to offer it as a kit, which flies standalone on D2.3 or C3.4 18mm reloads. It comes with a lightweight(14 grams) pointed cone but you can substitute a mini-bertha/mini-fat boy/bertha cone or print one using a thingverse design by Jack Hydrazines... I'd offer it with the bertha cone but no-one sells that cone separately.
I built it two ways, with servos mounted on the bottom which I think looks better, or with servos mounted on the top of the wing recessed into the body tube for people that may want to use it as a non powered parasite glider on an upscale(2.33x) Orbital Transport booster and are worried about the bottom mounted servos catching on the mounting on the booster. First one shows with stickershock markings, second I did hand cut vinyl using some 1/4" and 1/2" cut vinyl letters I picked up at Hobby Lobby and some of my company decals I cut up for logos...
It's 19" long, 15" wingspan, BT-60 based and right at 5 oz ready to fly(142 grams) with d2.3 motor. It flies very nicely. If you were going to build it as a parasite only you would need to move the receiver and battery back to mid body and cut an access hatch to keep CG which would need to be 1/2" further forward than the boosted version to keep the glide CG and up elevon settings needed to match the settings on the original free flight model.
The Prototype used HS-55 servos which weigh 8 grams each and I used 2.5 gram servo extensions to attach to the receiver, but I found I needed to push the receiver back into the fuselage a bit for CG.
On the second I used hs-65 servos which weigh 10 grams and used no servo extensions and removed the receiver case which saved 8 grams, and I needed 4 grams of nose weight, result was they were within 2 grams of each other ready to fly.
Here is a pre-decal flight video, flies very nicely.
