Antonov An-2 (oz8961)

About this Plan

Antonov An-2 Colt. Radio control sport-scale model Russian biplane, with 'Utterly Butterly' paint scheme. For 19 to 30 engines and four functions.

Quote: "1995 saw the introduction into the air display scene of an ANTONOV AN2 (code name COLT) aircraft. Bought and flown over from Nyiracasa, Hungary by display pilot. Vic Norman, HA-MEP was sponsored by St Ivel and teamed up with a Fournier RF4, it promoted the then new product 'Utterly Butterly'.

The AN2 is a 1947, 59 ft 8 in span workhorse biplane with slow flying ability, Vic described it as: A big ugly, but oh so beautiful biplane that hovers like a big cloud. Peter March described it as 'Utterly Uggerly', but with a character all its own. It could never be described as graceful.

Love it or hate it, it does make a good model subject. If one keeps the all up weight around the 13-14 oz / sq ft mark it can be made to fly quite slowly without the need of the enormous 'flappery' of its real counterpart. At a tad over the scale of 1/14th, the wingspan is 50-1/2 in, suitable for 0.19 - 0.25 engines.

CONSTRUCTION: Always on the look-out for something 'different' (apart from design) I have evaluated blue foam board as a building aid for the 'curvy bits', although a traditional balsa/ply basher, I have been surprised how easy it was to integrate foam with balsa (so, OK, I'm behind the times!) Apart from weight saving I found subsequent finishing was easy without
recourse to epoxy skinning or equivalent. Another novel feature is the engine cowl, but more about that later.

Build two fuselage sides identical (except for L and R handed former D), making sure the ply is on the outside. When the second side is dry and while still pinned to the building board, fit and glue formers B and C ensuring snug fit and square, fit and glue second side on top, again checking squareness and alignment. When dry remove from board, fit and glue former A and being tail posts together, a fuselage jig will ensure alignment.

Fit 3/16 cross braces and bracing strips behind former A. Glue 1/4 in rails for top wing support between formers B and C, fit 3/32 hard sheet fuel tank floor, infill sides with 1/16 sheet back to former C..."

Note the misspelled title block on this plan says: "Antanov An-2".
