Large Avro Arrow RC Rocket glider
Decided to share here as well as FB in case anyone actually reads the glider topics, I am doing a kit of this that is 34" long with 2" tubing and 6mm depron wings, but I decided based on the CG and flight performance it might work as a 1.5x upscale using single ply 9mm depron, 3" tubing from Estes along with their lightweight cone, and just come in light enough to fly on the G-12 32mm reload, this will boost up to about 28 oz, this came in at 27.4 rtf with motor. Elevon control, 48" length, 37.5" wingspan, details added with sharpie pen, and hand cut vinyl for color except for the black on the nose. The roundels and lettering/numbers from stickershock. Intakes on the sides are just profile plates to give the look but be lightweight. It's about 1/17 scale, of course there are concssions to scale to make it work with the tubing/cone etc, but it looks the part.
Launches off a rail as per usual for me. Should boost to round 600', has a wing loading of 6.5 oz/sq foot after burnout which is pretty good at this size. Two servos, single 500mah 1s battery running them and the rx directly, very lightweight. CG shift covered by a glide trim setting only, no fancy balast adjustment. The cone came in at 2.4 oz after cutting off the base to allow mountng the battery, and only 2.5 oz was required for CG. Frank |

VERY cool! Love the Avro Arrow - would have been an awesome jet in operational service! Beautiful work!

Wow, what can I say, that is an amazing version of our legendary (and too short lived) CF-105!! My Canuckian heart practically skipped a beat just reading the thread title; and the description details and picture brought me close to cardiac arrest. Wonderful job!

Have you ever done a twin engine bird? It would add a little weight and complexity, but you need a little more challenge with your skill level!
The Avro reminds me of an F-5 Vigilante. I don't know why...maybe because of the single vertical stab when everything these days has two. The F-5 already has quite a bit of wing area, especially the reconnaissance version, so you wouldn't have to enlarge it too much to get a usable glide. It's not a delta, though. Aviation buffs can tell me for sure, but I think the Vigilante had the first flying vertical stab (all moving like horizontal stabs that were already in use). I'm sure it used the same J-79's as the F-4 because those were the beasts of the late 50's and the Vigilante was a pretty good size plane.

a "little weight" is an understement. In a tail mounted model like this for example, if you were to do two G-12's you add another 4.5 ounces in the tail which means at least 2.5 to 3 ounnces in the nose to balance, your CG shift will be even bigger now at burnout. Adding more than half a pound starts to kill glide, then you risk lighting two and not having one light....I like to keep it simple.
I've modeled the Vigilante before, I think the Arrow looks pretty close to the Rapier F-108 prototype which is also North American. For these bigger ones to fly in the G-12 long burn motor, weight is critical and it's a very fine line in cg placement, length, control placement etc to get it to work, a little mistake here and there and you add 4 ounces in a flash and then it's dead.
