3.3-Meter Competition F3J Sailplane
The 3.3M Sharp Wind is an all molded competition class thermal sailplane, designed for F3J soaring. This plane is very large, very stiff, and very strong. Able to take 2-man hand towing on the strongest mono line with ease.
The construction quality is amazing, with lots of innovative and well thought-out details that really set it above most of the other products in our fleet.
The full flying cross tail comes completely done right out of the box. The rudder is hung and gap sealed, the full flying horiz. stabs are simple to set up or take apart in the field with custom machined aluminum hardware, and the nose canopy allows generous access to your radio gear.
The fuse is pre-setup for the monster carbon wing joiner, wiring harness, and locator pins (pre-installed in the wing roots), and has lots of carbon tow down the length of it for maximum strength on winch or towed launches. The huge two piece wing is your typical glass, balsa, fiberglass skin construction, with full span carbon main and trailing edge spars, and the exterior finish is a gorgeous high gloss paint, in a variety of schemes. We never know what we are going to get, so ask before you order if you are particular.
The flap servos are uniquely mounted on the flap cover, which is then securely screwed into the wing. Very stable, slop-free connections are easy to accomplish with this setup, and control horn adjustments are a breeze with full access to the servo horn. We wish all our planes were this easy!
We recommend using a 4 cell 2500 mAh NiMh or larger battery pack, HS-5245 servos for the tail group (or similar), HS-5125 flat wing digital servos for the ailerons, and servos no larger than HS-85MG's for the flaps. Our preference is the Volz MicroMaxx or JR 368's for the flaps, but HS-5125's work also.
