Slopeing RICOCHET DELTA, Ugly but it flies Great 

Thank You! Ha ha... Yes I've had many hours of enjoyment with it. Thanks again!

Ha ha he had a-lot of trust in me lol. I didn't know he was going to go catch it. That youngster can fly his butt off BTW. Yes I got lucky with this design, I kinda guessed at a-lot of the dimensions, it felt right but no real math went into it. A rule of thumb design that worked out. Thanks and enjoy the rest of your Labor Day.

@@robertshaver4432 Lol, at least he didn't stomp it out! It's nice when a plan comes together and works better than you think it would, more skills! I've been going to Calico dry lake on Wednesday and Saturday pretty much just flying the plane I want to try to slope... Someday that is! Lol! Thanks, cheers and enjoy!

Oops missed your comment! "Thank You Very Much" for the complement! Lets' Fly! Robert

The vertical fins are indeed ever so slightly toe in or inwardly orientated. bottom fins are to protect the bottom monocote on landings, but More importantly, they keep the craft "tracking" straight whilst sliding to a stop. If it slides and rotates sideways to the wind (it will without the bottom fins dragging it straight) "it flips over" and breaks the top fins. FYI bottom fins are lite ply and are "sacrificial"! wood grained "to break off", not out: bring glue. My top fins are 9" tall with a 6" root chord and a 4" tip chord and reside 14" out from center (28" between top fins) The Trailing edge sweeps about 2" rearward to even with the Elevons T.E. whilst mounted 3" forward of the Elevons T.E. Have tried "many" fin sizes/positions this one fights the adverse yaw best "hands down"; will add 1/4" chord) Here's some numbers: Finished size 24" root chord at 3-1/16" thick @ 25% chord. Fully Symetrical, I literally cut two right wings and flip one over. Polystyrene foam light to med density; hot wired. Tip chord 10" at 1-1/2" thick @ it's thickest point (@25% chord) Each wing panel spans 32" which = a 64" span + I have 2-1/4 inch solid balsa wing tips (shaped like a river rock) Elevons are full length and 2" chord The trailing edge is "straight" (all sweep is LE sweep) Dihedral is that the top of the wing is "flat" and bottom of the wing shows all of the dihedral (which is little). CG is 15" forward of T.E. taken anywhere along the T.E span (no T.E sweep)This a "mines at" measurement. CG @ 15-1/2 to 16" forward of T.E. at first! The nose is 13" long from the L.E. "point" (L.E. root) and balances with "some" nose weight My next one will be 14". fuse is lite ply which tapers to the CG point on the bottom; the top goes nearly all the way back to the Elevons to conceal servos/ pushrods, (battery in nose) and is 2" wide it's top hatch is nearly from L.E. to T.E.; screwed on. Control throws: you will need a-lot of up trim 3/16" Elevons up (more than 1/8th of an inch !!!) Max your control throws whereas full up and left almost brings the left elevon to vertical; prob 75 to 80 degrees. down will likely be slightly less because of the up-trim but get all you can is the idea! Whew, that should it, if you make one I'd sure like to hear of your successes. Robert

Robert - have you drawn up a plan for this yet

sorry for the late reply. No plans are really needed but I do intend to do a build video someday. It's hot wire cut from polystyrene foam using the above dimensions. I sheet the leading edge with 1/16th balsa back to about 4" at the root and or tapering down to 2 1/2" at the tips. The trailing edge is sheeted same but only 2" all the way across, I do put trailing edge wood on for the hinges to attach to and the sheeting goes over it, same on the leading edge but it's for the sheeting to adhere to and to harden the leading edge and then add another "true" leading edge piece after I've sheeted it to round it properly, I then put effectively what is 1/2" cap strips (1/16" thick sheeting cap strips) from the leading edge sheeting to the trailing edge sheeting (looks like I've cap striped "ribs" but it's on the solid core foam wings). after joining the wing halves I put 4" wide 1/16" sheeting across both wing panels roots to further join them; note the grain runs towards the wing tips to provide stiffness. The Dihedral is flat enough that you can bend it around the bottom dihedral peaks so to speak and the top is easy in that there is no apparent dihedral across the top of the wing (flat). until I find time to make a build video that's about all that I can offer in script. again sorry for the super late response the hobby keeps me busy with "other" doings. Robert

Insanely light, everybody does it there own way ( I like oz per Sq. inch so, 0.047 oz per sq inch): Derive your way via: 3 1/4 lbs at 1,108 square inches of wing.

My other videos' "Script" has all the dims one would need to Scratch Build it! BTW

Monterey Ca. is the Pennunsula 5 mi. on the left and Santa Cruz is way across the bay on the right. This is Marina which is on the north end of the "very" flyable Dunes that extend South from there to about Seaside. Much to do here, World Class Aquarium on Cannery Row... Yep Steinbeck Country; A wife happy destination Guaranteed.
