Have you found the front landing gear of the Elfi to be less than secure? The design has the assembly easily shearing loose or off of the two small screws holding the landing gear wire. I modified the one on Elfi #2 to hold on a little better. I changed out the front landing gear on Elfi #1 completely, using a control horn for a 1/2A size model and a small wheel. Looks a little odd but it is working.
