JAS-39 R/C ✈️ Pushing the Thrust Vectored Gripen!

Great R/C model aircraft of the JAS-39 Gripen performing aggressive aerobatic flights and making use of a thrust vectoring nozzle upgrade!

I hadn't uploaded new Gripen videos in a while... apologies ! ! ! :D

After some crashes and complications for the past year, the Freewing Gripen is finally back in the air and here go a few cool clips of the most recent flights after finally solving the issues that were causing me to suffer so many accidents :)

On the downside, the plane is now way too nose heavy for my likings (which you can notice from the ridiculous amounts of elevon deflections used to perform turns and maneuvers) but I'll eventually fix that. The important thing is that she's back and she's rocking again! ^^

Shameless plug: if you want to contribute to my work, please consider having a look at some of my merch! ;)

The jet is powered with an upgraded 8S 80mm Jetfan EDF with a 1865kv HET motor. I had to cover the cheater hole with a mosquito net to protect my expensive investment from an otherwise inevitable FOD considering the conditions of my gravel-dirt runway so the jet isn't even displaying it's full thrust potential. This obviously has an effect on performance and current draw. Sadly this setup is too amp hungry and can only get two and a half to three minute flights with throttle management and 3Ah packs. The batteries also struggle to deliver the amps, despite being Panther packs that are pretty heavy/capable. Overall the Jetfan is indeed an improvement in performance over stock setup, but the short resulting flight time kinda defeats the purpose, need to go to higher capacity batteries, and using lower-C packs to keep the weight in check.
