Ion 1950's Futuristic Flying Wing - Pt9: Manifold fitting & Custom Exhaust- By O.F.W. (Peter) Fisher

The Ion Mk 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-plan...
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.

Good morning Mark. Yet another enjoyable video. I was quite surprised that the exhaust manifold made no difference to the running of the engine. Brilliant. Love the little anvil.

Good morning Terry, really appreciate the comment. Hope you are enjoying the warm weather, will you be visiting Old Warden flying next week?

Unfortunately at this moment travelling is a little awkward for us as my wife is waiting for a major operation.

@@terryblackman6217 oh dear, so sorry to hear that, hope it all goes well and soon, all the best

Thank you.

Morning Mark. Wonderful build series you producing. Relatively recently discovered your content. I truely loved the Tomboy senior build - plus your flying wing crash re-build. Fantastic attention to detail. As a British modeller of pretty much similar age to you - its nice to keep learning new tricks and tips. This week I acquired lots of square steel metal blocks - after watching you use them. Not sure how I've built model planes this long with them. 👍

[@MarkRobinson555]

Thanks for the comment, really appreciated, so pleased you enjoyed them. Yes, the blocks are so useful, I couldn't build without them 😀

[@ravebrave8866]

wow great muffler.. but if you could use a small can in place of the pipe the sound would have been reduced... to tell you I just love the engine... it can never be replaced with electric motor..

[@MarkRobinson555]

Thanks for the comment, pleased you enjoyed the video. 😀

The Kingcat Deluxe diesel came with a similar exhaust pipe. I have run mine with and without it, noticing precious little difference in sound level or performance, but it certainly gives a different look. Unfortunately it does just go straight back, so still sends oil over the model. A later exhaust variant included an expansion chamber that is more effective in reducing noise.

[@MarkRobinson555]

Hi David, thanks for the comment. The Kingcat does look great with that exhaust, but as you say going straight back is not the most helpful. Never seen the exhaust with the expansion chamber, I will have to look it up. 😀

Another cracking video Mark - thank you for taking the time to produce them.
Does fitting the silencer make starting more difficult as I assume you can’t prime it through the port. Do you just choke it or squirt fuel down the venturi instead?

[@MarkRobinson555]

Hi there, thanks for the kind comment, greatly appreciated, the engine starts just fine with a choke, the muffler doesn't seem too make any difference to the power or starting

Nice work, looks really nice 🙂

[@MarkRobinson555]

Thank you! 😊

Perhaps I have missed it, but when using beam mountings for an IC engine, if a small angle of side thrust is called for, how to you mark and drill the bearers to an accuracy of less than 1 degree?

[@MarkRobinson555]

I would drill the holes in the beam slightly bigger than the mounting bolts so the engine can be moved side to side a little and adjust as required

[@davidpoll1042]

Thanks
