You got that dialled in really quickly. With catapult gliders I always seem to struggle with extreme control sensitivity in the high speed launch. Nice work!
Holy cats, Batman! I have to re-watch this...is it making a complete 360 to the right before taking off downwind and slowly turning left? What an amazing glider!
Hermosicimo modelo, yo hice uno con poliestireno y me quedo muy bien, solo que nunca logre encontrar su centro de grabedad y no pude kastrarlo adecuadamente, por lo que no vola a bjen. Me encantaria volver a hacerlo.¿ por fabor, podria indicarme como lo lastto, cuantos vramos uso de lastre y donde se lo puso al modelo?

Thanks - I balanced the model using a few grams of clay at the tail. The balance point is shown on the plan available here: outerzone.co.uk/plan_details.asp?ID=3416
Excellent - my that one flies well. I have a pair built many years ago when my children were tiny. I now use them to indoctrinate my Grandchildren! Thanks for sharing 🙂
Beautifully built, flown, and filmed. Really fun to watch. How did you make trim adjustments on this model? Always curious to know with catapult gliders.
Thanks Oliver! On this one I used surface deflection on the rudder (tweaked the bottom of the fin to the left) to induce transition after launch, shims in the fuselage slot to reduce reflex at the TE to tame the loop, bent the elevons by rolling them over a glue stick container to reduce reflex and set aileron trim, used tip weight on the right wing to tame a left spiral in glide, and used tail weight to get the cg in a workable place. There was a lot of iteration of tail and tip weight to get flights like the last two in the video. I think there's a bit more launch height to be had using 1/4" rubber (the second day's flights were all on a loop of 3/16" rubber) and trimming a bit more loop out of the top of the launch. It's been a fun and educational model to trim.
I just cropped the canopy, lettering and tail insignia from this profile: 1000aircraftphotos.com/Contributions/Visschedijk/Additions/EFW_N-20.2_Arbalete_side-view.htm. Hope yours flies well!

@@michaelkelly7338 ah, thank you. I already finished it but I might add it on. The files didn’t work for tissue printing so I airbrushed on decals, turned out great.
Me and my sister made these in the 1960s and the 70s and flew them and lost some in my parents large field on the estate great fun.
Great little flyer!
Really nice! Thanks for sharing ❤

That was impressive
Great set up job Mike. Nice looking jet.
Has good looking L/D and covers a lot of ground quickly.
Nice job on that model! Liked watching the progress. Thanks for sharing.
Awesome Love cat gliders wish i had a big field like that all i have is a base ball field lol
Fantastic!
Very nice.
Love it!

What would it do with a really long ground attached catapult?

Where is the cg on this beauty?
Hi Dohrm - I'm currently flying it with cg 2-3/8" aft of the leading edge, measured at the wing root.

Hi Michael
How was he able to eliminate the looping effect when launching it with a catapult. Cheers
I reduced the reflex on the aft edge of the wing to tame the loop. It's still there, just not as pronounced.
@@michaelkelly7338 thanks !!!
Hi, I’m building this and almost finished, do you have a pdf of where you got the tissue print? It would be easier rather than airbrush
I just cropped the canopy, lettering and tail insignia from this profile: 1000aircraftphotos.com/Contributions/Visschedijk/Additions/EFW_N-20.2_Arbalete_side-view.htm. Hope yours flies well!
@@michaelkelly7338 thank you!
@@michaelkelly7338 where did you get the outline for the main landing gear? I’ve looked at dozens of 3 views and can’t find any.
