Congratulations on your maiden flight! I am Japanese modeler who loves RC flying wings. I hope I can see the next flight soon. Again, congratulations!!
Whew! Talk about Mr Toad's Wild Ride! There was a time I could take on little hot rods like this, 1/2A and such. In fact, I still have a Cox TD 020 that's never been fired. But not so much anymore. I look forward to your next debrief, Mark. Cheers!
Great to follow your build and flight. I built an Ion for free flight in 1976, only to have it crash into a barbwire fence at the end of its first flight. I vowed then to rebuild it RC some day. I have a second kit and you have been an inspiration showing it can be converted. I will give it a go with a brushless outrunner this coming winter. I'm guessing you are using very limited throws on the elevon setup. It did not look twitchy up there and the glide was superb as always with this model.
Thank you for the comment, greatly appreciated. As you thought, it wasn't at all twitchy, I think the 3 fins give in an inherent stability. The throws are 8mm up and the same down, but think I will probably increase them. Looking forward to getting it back in the sky.
Hi Cliff, thanks for the comment, no didn't change the engine it is still the PAW .55cc which is very similar in power to the Frog 80 on the plans. Looking forward to getting it adjusted and back in the air! Didn't look good in the air? 🤣
Nice video, mark, one thing I would say is that the fuel tank problem might be solved by attaching a tube to the exhaust for back pressure to push the fuel in the engine so you could move the fuel tank inside the fuselage
Unfortunately this does not work well with Diesel engines. Part of the exhaust gases is water, which mix well with methanol, but not with diesel. The water will collect in the lower part of the tank causing the engine to cut off.
Nice and stable. I wonder if reducing the reflex would help. As the original was F/F, it would have been designed to climb under power and transition to flat glide. Maybe you could mix this in using two flight modes on a switch. I use this on some of my hand-launch models that torque left on launch. Usually, its a bit of right rudder and a tad of up. As soon as its away I hit the switch which neutralises the trims. Best of luck.
Thank you very much, really appreciate your comment and suggestion. I do have a mix like you suggested on one of my flying wings, and it may well end up having one as well, even if its only for the initial launch. Can't wait to get it flying again 😀
Swept wings produce very little lift in the midsection, cause airflow is going outwards. The engine delivers air with high angle of attack to the midsection, thus significantly increasing lift in the middle of the wing (forward of CG) as long as the engine runs. I doubt that more downthrust will help. To the contrary, I would set engine downthrust to zero or even plus 1°, and make another extended glide with little revs and just a few seconds run time. With zero downthrust the airflow around the midsection is more or less the same with engine on or off.

Hi Mark, nice one. Maidens always makes me a little bit nervous, you handled it well. Always something to sort out 🙃
Thanks very much, really appreciated 😀

Glad you enjoyed it! I am looking forward to making some adjustments and getting it back in the air, great fun! 😜

Rodger that.
Once sorted out you will have a good model there. She has more than enough power. Brilliant.
Hi Terry, thanks for the comment, looking forward to getting it back in the air soon 😜
Flying wings are always tricky. Cant wait for the next flight :)
Thanks very much for the comment, be flying it again soon 😀
I hope you have recovered from that heart attack there Mark. Close one with the distance. Nice job.
Thanks Norm, looking forward to getting it back in the air soon

Surprisingly powerful climb out, did you fit a bigger motor ... thinking of the downthrust here? But didn't look good in the air 👍

That's a bit spirited 😂

Looks reminiscent of sci-fi aircraft from old comic books.

think it was ok back in the '50s to go up on power (just like freeflight models) - good recovery though ;-)
Thanks for the comment, its appreciated
