List of my Model Aircraft

First Re-creation

This was a much loved classic model in need of re-creation. The original Electric Serenade was designed for a 540 motor powered by 6 cells. In this model a brushless motor powered by a 3 cell Lipo was used. Two wing fixing nuts were used inplace of elastic bands. Flaps and Ailerons were added to the new wing. The model crashed on 8th March 2011. The wing was irreparably damaged.

Second Re-creation

A new wing was built without flaps and ailerons. The plan of the wing was followed and the wing cross section incorporated under camber, similar to "Cmelda". This model initially flew well but crashed on 15th April 2015, in a very similar way to the earlier re-creation. The wing survived but the tail broke off. On close investigation the radio/crystal seemed doubtful. It was suprisingly difficult to get a replacement Futaba R136F , but one was obtained from France. The tail was refitted, using extra pieces of ply , to the fuselage and lead was added to the nose to rebalance the extra wood. After a few false starts The model flew beautifully on September 8th 2015.
