Lipo Man Posted October 20, 2023 Share Posted October 20, 2023 I built the Tony Nijhuis Hunter from his balsa kit. I was (and am) delighted with it - it looks great and cruises along pretty well, but loops aren’t brilliant and it can get “squirelly” in a turn. I also built an own design 64mm jet made out of insulation foam from B&Q. It also cruises along well, but isn‘t great looping and can get wired in a turn unless you keep quite a lot of throttle on. It uses a wing that is basically a flat plate - not unlike the TN design (only more so). Anyway - I experimented adding a more curved upper surface to the wing on my foam jet. Long story short - it had a very significant positive effect. It seems a flat plate wing at a high angle of attack (such as looping or in a turn) generates A LOT of drag, and with a more conventional section my jet keeps up momentum MUCH better. Short video of the experiment here: So - now I’m really tempted to do the same thing on my Hunter. Sharing for the interest of any like minded souls with TN 50mm jets who may also be interested to give it a shot! 2 1 Quote Link to comment Share on other sites More sharing options...
