(Built from Clancy Aviation kit)

This model was originally built with interchangeable motor pods (see Review Article for more details). However, the Speed 400 version was soon abandoned.

 

After 13 years and nearly 400 flights the Lazy Bee was looking a little tatty so it was time to bring it into the brushless age - see last column of figures below.
