I am sure it is a Vandal. Many thanks Richard, John and Ian. Apologies for not replying sooner. I can't find much about Masterline or the Vandal online. Presume Masterline disappeared a long time ago? Everyone kept telling me it was a Maricardo so I bought the plans from Sarik Hobbies only to discover that it was a completely different plane! I converted it from elastic bands holding on the wings to a big bolt. It came second hand with an OS46 AX Max fitted for £50. This is what it looked like after a crash but it is almost repaired.
