Sukhoi is synonymous with performance.  From high performance military aircraft like

the Su-27 to the aerobatic flagship Su-31, airshow spectators all over the world have

witnessed exciting, cutting edge performance by aircraft bearing the Sukhoi name.  The

Su-26 put Sukhoi on the map for performance Russian aircraft.  Later versions such as the

Su-31 continue to awe and inspire flight hungry folks today.  But unlike its single place

counterparts, the Su-29, with its power and almost frightening roll rate is one of the few

aerobatic aircraft made for two passengers.  The longer canopy and much less curved

landing gear give the Su-29 a very unique look.  In modeling, the Su-29 is very rare

indeed.  It is not the cliche of the field.  This Sukhoi is no slouch either.  Great power to

weight ratio and a light wing loading make this ARF a true high performance 40 class

aircraft.  The Modeltech Su-29 ARF was developed for modelers, by modelers.  The fiber-

glass cowling, preformed aluminum landing gear and fully adjustable tail wheel assem-

bly are just a few examples of the high quality that will give your Sukhoi longevity that no

"plastic" ARF plane can provide.  An all wood airframe covered with iron-on polyester

covering means maintenance and repairs are now possible.  It’s built with the same quali-

ties hobbyists want in any kit they would build themselves.  From all of us at Modeltech,

please enjoy!
