As usual we used stable tubular carbon spars, precisely lasercut wood parts, a very simple construction (Hoellein-3D-puzzle), easy and forgiving take off-, flight- and landing characteristics, large speed range due to the modified AG35 section, ecxellent handling and thermal characteristics. Easy purchase of single spare parts and assemblies. Made in Germany!
New: 2860mm wingspan, 920g flying weight, three-part wing with multiple dihedral and attached wingtips, lightweight rudder and elevator constructed in a solid interlocking framework, removable elevator (optional) mounted in front of the rudder, 90° deflectable landing flaps enabling you flying vertical descents, integrated wing connectors in the main spar, innovative (tool- and tape-free) fixation of the outer wings. Vertical descents with deflected landing flaps (90°) and landings avoiding the vortex zone on steep slopes are now possible without any problems.
The recommended drive - containing the BL-outrunner Hacker A20-22L Evo, a 3-cell LiPo with a capacity of 1300mAh and the CamCarbon 11x6 prop - allows a many many climbs to thermal country. Due to the light weight, a motor run time of 5 to 10 seconds per climb is sufficient.
Main feature of the model is the tubular carbon spar, onto which the lasercut ribs are kind of "threaded". Stylish wingtips ensure an elegant appearance. Our Introduction F5J has the most beautiful and elegant fuselage of all of our Gruener kits so far and it is consistently designed for the use of small brushless outrunners. The flying weight starts at 920g. Considering a wing with nearly 3 meters wingspan and a wing area of 65dm² (wing loading approx. 14g/dm²) you might imagine the thermal abilities of this design. Due to the long fuselage and the multiple dihedral in combination with the wingtips, the INTRODUCTION F5J has excellent flight characteristics.
The fuselage made of balsa is reinforced with light plywood in the front section. A precisely shaped milled part is already prepared to fix the motor Hacker A20-22L Evo. The kit contains, besides of the lasercut parts, CRP-spars, GRP-leading edges, all the small parts and linkages needed to complete the model. All the kits of the Gruener-CNC-line include a multicolored construction plan scaled 1:1 and a fully illustrated German construction manual.
Glue, covering film, power- and RC-components are NOT included in the kit. As covering film we recommend ORACOVER or ORALIGHT iron-on film.
