RE: DL-50 engine
They are some of the best wood ARFs made, well built, light weight, great flyers. I've had several over the years and still have a 50cc Yak and 100cc Extra that I love to fly regularly. Their only draw back is the seeminglynever ending ownership and brand name drama that hascaused a support parts nightmare for many that have needed them, it's supposed to be improving though.
