R.T.F Hakuna Matata mk2, designed and built for Open combat by Mel Lyne. An all foam R.T.F version is also availabe

 

Open Diesel Combat

Unlike our Vintage event, in open combat there are no restrictions on the model design or methods of construction. This allows a wide variety of foam and wood models into the event. Most flyers may choose to build and fly foam models but the all wood vintage models can still be used and remain competitive.  

Engine size has been increased to .21 cu.in. with no restriction on the type of diesel engine used. There are no prop restrictions so any size or make is allowed. Of course those pilots using glass props will be at a disadvantage in a dork as opposed to those using the durable Taipan, Kavan or Grish nylon props.

For those flyers who want to go faster the maximum speed limit has been increased to a whopping 70 mph towing a streamer.
