Title: Joker-Plank wing Post by: rahulroy31 on July 04, 2022, 10:56:50 AM A 1m span plank wing which I named Joker :)
Dimensions and details :- Span = 1000 mm Root Cord = 265 mm Tip cord = 175 mm Sweep = -25 mm (slight forward sweep) Wing area = 220000 mm^ or 22 dm^ Airfoil = Phoenix mod (85% thickness) Elevon = 25 mm cord Full span elevons Vertical tail = 136 sq cm Electronics Motor = 2206 200KV Prop = 7x4 Bty = 2S 1000 mah CG - 30 mm from the LE at root cord / 55 mm from LE at the wing tips... AUW = 310g, Wing area = 220000 sq mm, Wing Loading - 4.65 oz/sq ft, Wing cubic loading - 3 The wing is hotwired from EPS (Thermocole). It has a built-up 10mm CF tow spar and skinned with 32 gsm fiberglass at 45 degree bias. the wing tips are EPP . The fuselage is only in the front portion to house the ESC, RX, Motor and battery.. The vertical tail is stuck on a 3 mm CF rod and glued to the wing TE... I had put the silver strip on one wing thinking it will help in visibility.. it does not help much. Need to be very careful to get the correct CG, even a couple of mm difference changes the characteristics drastically. I have put 40% expo in elevator.. Once trimmed she thermals well without much inputs without much inputs.. and turns are very tight without loosing height Here is a a flight video https://www.youtube.com/watch?v=s7lBZY6r_bI Title: Re: Joker-Plank wing Post by: pmahure57 on August 27, 2022, 08:35:34 PM are you selling ?
