Hey all, wanted to post a pre-initial flight update :).
I’ve finished the non-cosmetic portions of this build. I’ve done the wing box modification, as well as the battery tray and nose gear reinforcement plate from Thingiverse. The two upgrades I placed the most thought in were the power system and how to get this jet to stop, so I went two routes on that: adding thrust reverse and magnetic brakes. I’m really underwhelmed by the effectiveness of the thrust reverse, but it’s a means of adding some resistance with no weight penalty, so I could see why some might opt only for that. The magnetic brake setup is really effective for the small weight penalty. Given these wheels are only a few ounces heavier than the stock wheels and very near the CG, I wouldn’t go any other way. Here’s a video to show what can be done; it’s easy to see that spooling up the throttle with the brakes on is a great way to use as little runway as possible. And to see that I’m able to accelerate to roughly 30-35ish MPH and stop in such a short distance is really encouraging. These are the 65mm magnetic braking wheels from JB Hobbies, I got them from Efflux RC.
There is a slight uneven braking which is happening, but that should just be accepted. I purchase an Assan AG63 pro as a possible means to solve this but quickly found it to be unreliable and pulled it out. I may end up with something fancier in the future, but for now I think this will work fine and if necessary I may just add a nose-wheel gyro.
Enjoy! And if anyone has experience programming the JR 28x please LMK, I’m stuck with inhibiting flaps while wings are swept.
