About this Plan

Trishette. Radio control sport model.

Quote: "RM Plan Feature. A no-fuss sports/trainer for electric or IC. Trishette, by Adrian Britton.

I expect many of you will already know the 'Trisha' design by now, and I have built and flown the model in many guises and sizes, from 36 in span to 90 in, with camera and toffees. However, Trishette seemed to be about the right size for the more popular small power plants available, and is easily transportable - I hope you enjoy building and flying her!

Format. Power under 1 cc and electric up to 3 channels, use mini servos and L/W flight pack 225mah. 1 cc and up - up to 4 mini servos or two standard, still use small flight pack.

Electric power formula. MFA Mini Olympus unit, 8 x 6 Taipan prop; BEC speed controller and Overlander 1000mah 7.2 or 8.4 v Panasonic pack with mini connectors. Maximum flying weight 28 oz. Lighten the tail framework and use tissue/Litespan or similar.

Prototype formula. PAW '100' diesel with carb, standard receiver, 3 mini (133) servos and 225 mah pack. Fibafilm (blue) Litespan (White). Finished up at 23 oz with some fuel! More power than needed with scintillating aerobatics (for rudder/elevator)! Pottered around on about 4000 rpm (for about 1/2 hour!).

Wings. The wings are best built first. Produce 22 ribs (and a 1/16 in ply template) which are perfect, and use a couple of these to line up the 3/16 in sq med/hard lower spar, the packed up LE and the prepared and slotted TE (do these as a pair). Pin these down and add all the ribs. The wing tips can be prepared and fitted, angled-up as shown. Triangular gussets go in next.

The top 3/8 x 1/8 in spruce spar will fit now, having chamfered the end to meet the wing tip. Remember to angle the root rib slightly to allow for dihedral when joining the wings. When dry, use a sharp blade to cut away the first two ribs at the rear of the spars by 1/16 in to accommodate the 1/16 ply dihedral brace when it's time to join the wings.

The 1/16 in sheet vertical grained webs are then added and glued to the front of the top spar in the first three hays only. Small strips of scrap 1/8in balsa are added to the gaps between them and the lower spar when the wing is removed from the plan..."
