This video is mainly composed of photographs showing the steps for the building of Hobby King Piper J3 Cub 1800mm.
The packaging of the kit is done perfectly well and the unpacking was uneventful. The numbering of the parts were lazer written on the balsa and was very easy to discriminate and detach from the laminates. I used a #11 scalpel (hobby knife) for detachment.
The plans are actually not plans as there was only one wing plan (right) and you have to use your imagination to build the left wing (just do the opposite), an issue if you are a rookie like I am. The rest were photographs to show the way.
The kit is basically planned to be an electric motor driven unit so there is no fuel tank present in the box and have to be purchased separately.
The servos planned are actually 2330 gr servos but standard servos can be installed with little modification.
The rudder and elevator servo holes are placed in the cockpit region but no pushrods for this distance are present in the box so you can make a change for the elevator servos like I did and place them at the back of the fuselage.
The cowling was white in color so I had it painted before trimming and installation.
The main landing gear are not planned to be screwed to a blind nut but just screwing into the balsa which I believe will not be resistant enough for harsh landings or take offs from harsh surfaces so you better make some modifications before the glueing of the bottom part of the plane.
The most delicate and I think most important flaw in the planning of this model is the way that the wings are to be held together on the plane during the flight as this completely relies on the struts that will be attached to the thin layers of plywood with a couple of screws so I designed and created a wing bolting system for my model and this eliminates the necessity of the attachment of the struts for flight but render their attachment to only for scale detail purpose. Nonetheless the struts are made from aluminum and add a lot of weight to the plane which is not desirable on an electric driven plane.
Finally I am using a Rimfire .60 motor for this unit with a 12x8 Master Airscrew E Propeller which will be driving a max of 63A. The system will work with a 6S 5000mAh 50C LiPo battery.
Hope you enjoy this presentation.
