Ion 1950's Futuristic Flying Wing - Pt15: Test Glides: Setting the Trim - By O.F.W. (Peter) Fisher

The Ion Mk 20 is a great looking flying wing from 1957, designed by O.F.W. Fisher and English designer and owner of Performance Kits. He was often known as Peter Fisher. The Ion has a 33" wingspan and was originally a free flight model powered by a Frog 80 diesel engine, however in this build it will be converted to 2 channel RC. The original design had elevons, used to give some reflex to the wing and they could be used to adjust the trim. In this build series these elevons will be servor controlled.
The plans for this build are available from Derick Scott at www.model-plans.co.uk/perform...
The link will takes you directly to where the plan listed, but you need to email the owner of the website, see details on the homepage, to get the plan. He provides a very good service.

Looks great Mark. From the first test glide you could tell it’s going to be a winner!

build light and fly better! Well done!

Thanks very much 😀

Brilliant test glide. I watch a lot RC videos where the inevitable crash could have been avoided with a gentle toss into some tall weeds before applying full power. That being said, you demonstrated real bravery hurling that thing the way you did. In my experience, launches like that usually end in a stall and nose-dive from 10 feet.
I will be looking for the maiden flight video!

[@EleanorPeterson]

Sweeeeeeeet! 🙂

[@MarkRobinson555]

Thanks, pleased you like it

[@asafgl4281]

Well Don, but why didn't you fire up the engine? It could be a good test flight

[@MarkRobinson555]

Thanks for the comment, pleased you enjoyed the video. I went to that site for the long grass and softer landing, but its not a site I can fly from.

[@racnc1]

Did you test the glides with a full tank of fuel?

[@MarkRobinson555]

No, should always trim and CG with an empty tank

[@NormanLedoyen]

Just fly the damn thing Mark. It is perfect and you are being to cautious and nit picking. 5555555
