Thats is really a very nice looking airplane, Nice job Crashalott, Keep up the great work, Chellie

Who needs a midget... I thought you were tagging along for the maiden flight? We could put some velcro on your ass and you should be good to go! Watch out for those low, high speed, inverted passes I like to do though!

Then I bend the 3mm Elmers foamboard around a 1 1/4 in pvc pipe to give it a shape of a "U" and use it to "skin" the formers. Here's some pics of the progress. The stiffeners are 100 for one dollar bamboo skewers. I create the former images using a graphics editor (Paint Shop Pro) then stick them to the foamboard with a glue stick. The former is cut out with a razor blade, the center hole is punched and the marks are transferred to the edges using a pen. Paper is then removed from front and back of the cut out former.
Plane is complete and test flights are done. Trim required just a little down elevator. Used a feebay chinese motor, 9x7.5 prop and this sweetie "gets little" real quick! AUW is 16oz with the commonsense 3s 1650ma lipo. Haven't decorated yet, but looking at calling it "Rocket 88"

Well if u haven't seen it at other posts heres my scratch built Spirit B 2 slope soarer. It's my 4th prototype of a model B 2 if u count the non-flying plastic testors model i built for scale references.Anyway it has yet to be thrown off a hill i only have to balance proper C G (33% of main rib cord i'm thinking) and it will be go for glide testing.Should it be controllable with out winglets or split rudderons for yaw controll I'll consider powering it up.It's made of 4 layers of polystyrene insulation foam laminated with elmers wood glue with a 1/8 th inch plywood (with lightening holes )main and outer ribs hot wire cutting templates.The upper airfoil i shaped by what looked good to me.The under side of the main body is shaped as a keel that follows the shape of the full sized acrft.It has the bird beak like leading edge.The outer wing panels are dow blucor 1 1/2 inch hot wired to the rib and tip ply.they are removable. THe outer panels are reinforced with nylon drywall tape and diluted white glue.This is a very light and strong method of reinforcing by the way .Cheap too.The model spans 92 " and the main rib cord is 36".The outer panels have a 9 " cord. The plane weighs 4 lbs 3 ozs. but if i have to add 5 ozs of nose weight it will come in at around 7 ozs. per sq. ft. wing loading.It has 2 hitec HS 81 servos operating the elevons which are located on the main body as in the full scale acrft.Its fuse is 1/2 " polystyrene hot gluded around bulkhead formers.The cockpit and engine nachells are shaped from some kinda light soft foam like florists would use i got dumpster diving for foam scraps.It's painted with rustoleum dark grey latex , the trim on the leading edge is radar absorbing black electrical tape.The foam was sealed with diluted white glue.I have about 20 hours work in it and only about 20 $ cost.Looks cool huh.

thanks crash I added 6 ozs nose weight which only moved C G 3 inches forward its now 41% of cord but the leading edge angle is very sharp at about 115 degrees so there is a lotta lifting surface behind C G maybe 80 % or more.So in my mind i see all that air pressure compensating for a rear ward C G.LOL.I'm laughing at my non technical engineering i feel like the german model designer in the movie Flight Of the Pheonix.Wheres my slide ruler.One of my all time favorite movies .Anyway i fixed a angle of attack prob. with the left outer wing panel .it had a few degrees more angle of attack than the right .enough to see by eye. So i filled and redrilled the trailing positioning dowel hole.Its veterans day, the sun is shining ,my son ,the assistant launcher is off school .we are go for test flight #1 I'll post the debriefing later T C Al

this thing will fly and it did .1st tried pulling it with a kite string at a run no go .8 or 9 mph not enough air speed. it did break ground surface tension once when i yanked the string felt less drag.So we climbed 20 yards up a 45 degree slope put a little up trim on elevator and i launched it 15 yards into some bushes.Everything looked good.Next had my son try to launch .Thunk into the dirt he cant throw it at flying speed.Ok a little more up elevator trim hand him the tx .5 more yards up the hill take out a d sized battery in the nose.I decide to throw at the bushes again with umph.3 running steps 15 degree attitude above the horizon ungawawh heave.off it climbs for 15 yards ,air speed bleeding off rapidly over the bushes and starts dropping nose down level wing., i yell up elevator to my son but with lack of air speed all the elevator in the world wont level it out.thunk it hits the park turf 50 yards out in front of us at a -45 degree angle of atttack basicly unhurt small crack in wing rib glue joint no prob.My son and I look at each other knowing i cant throw 5 lbs 50 yards and yell IT FLIES . I think the Wrights only made 100 ft. their 1st effort .lol.Anyway stay tuned more to come

Good grief!

They are making it sound like other vendors are steeling thier copyrights!!!

What a joke!

They are the ones doing all the copyright infringement!

Typical tactics for them and many other oriental vendors - steel everything you can and forget ethics.

Not to go off topic but... How exactly is HobbyCity infringing on anybodys copyrights?
While there are Chinese companies that do I'm not sure how THEY do it.
What is interesting about them is how they sell inexpensive motors that look, and have stickers, just like some other companies sell but they always seem to claim "it's the same series but custom wound for us" (:

Sorry but it chaps my nads that these motors are sold for sometimes twice as much money THEN people bash the ones sold by UH.
