The Smile F3K is a great discus launched glider from AJ Aeromodels. Like the Snipe it has very high aspect ratio wing, giving it a high launch and a great glide angle. The design shows a strong Snipe influence, employing similar pylon mounted tailplane. Like the Snipe the model flies very well, with high launches and a good speed range.

The wing and tail are beautifully molded from ultra-light spread carbon over a Rohacell 31 foam core. This makes the wing light, accurate, and comparatively tough and repairable if necessary. The lightweight tailplane (horizontal stabiliser) is mounted on a molded carbon pylon, which can be mounted above or below the boom, to the modeller's preference. The fuselage is a very rigid spread carbon molding, with a good sized canopy hatch, aiding the RC installation. The tailboom has an oval cross section to increase stiffness and improve the launch height.

The model is supplied with horns, pushrods, pull cable, torque springs, servo mounting plate and a very nice offset throwing blade. The wings are supplied in thin foam bags but fit nicely in our DLG F3K Wing Bags and the tails in our DLG F3K Tail Bags for greater protection. No build manual is available but there is some useful info in this RCGroups Smile thread, and some construction photos on Facebook here.

Although the completeness of the kit and the quality of construction and detail design is excellent there are a few small paint and surface finish blemishes, hence the reduced price. But do not let that put you off, these are still beautiful models and a fantastic bargain.

Hi I bought a smile Dlg from hyperflight it arrived very quickly and extremely well packed I used Mks Ds6100 servos and a lemon Rx with a 1 cell lipo the kit is very nice to build your have to think about your servo fitment but got all four on the servo tray supplied I cut the tray in half and took a little of each end then fitted the aileron servo first then rudder and elevator .went out with it on Saturday and had some great flights very smooth little glider launches great and flies great all good very pleased

This is my first cabin dlg ,Good glider , nice carbon for the price. Went together well , I would say would benefit from a servo tray to make the job easier and taking a lot of the guess work out. Havenít flown yet but will be getting out for madian flight soon.
Package very well and delivered very quickly good job hyper flight.
