JP hobby elec brake question

I started out with the Xicoy LGC-15 on 2S. Since the JP retracts can only use 2S the brake power is also limited to 2S from the LGC-15. I switched to the AG-63 to allow brakes to use 3S power. For a while it worked excellent. Perfect straight steering and braking. But then the brake outputs on the AG-63 stopped working. The steering still worked. So I went back to the JP brake controller that is now toast. I've been told that the heavier jets need 3S to get the stopping power from the JP brakes. That is why I switched away from the LGC-15.
Vincent, did the SM air brakes fit on the JP gear with out a lot of fuss or machining? Where did you get the SM 1/6 F-16 brakes?

Nothing major but i had to make up a new 8mm axle and drill / tap both ends for bolts to secure. Also the SM axles were 7mm so i had to replace those wheel bearings with 8mm type. I found a used set of wheels and brakes a few months ago on rc groups and bought them. I figured eventually i would be using them as the JP set would just not cooperate.
Thanks

Several of my club members have the same JP brakes on their L39's and use the AG63 gyro. They claim the 63 puts out more voltage to the brakes than the stock JP controller and the brakes engage at higher speeds. Its worth a try if you are not able to do the conversion to air.

Depends on your project. I've used both successfully. For smaller to midsize aircraft (up to approx. 35lbs) the AG63 is fine. For larger aircraft ( above 40lbs) the LGC 15 is the way to go. This is mostly for the ability to set (increase) the resistance amperage for the heavier retracts. This will allow the gear to complete full retraction against the weight and wind resistance (including gear doors) after takeoff.

This is the solution, in my opinion. I have a 35lb Xcalibur+ that I converted to JP electric gear, and I have the same problem, no brakes at speed (same bigger wheels with the plates in the rims). This Xicoy controller allows up to 12v (3s) and has the pulse feature which is great. Hard to get though, Dreamworks is out of stock! I had to order direct from Xicoy which costs in shipping. I will let you know if it truly works when I install it soon. Shame that JP does not make their controllers to work properly with the bigger models!

So, I received the Xicoy controller and installed it in my Xcalibur+. I now get 12v to my brakes. The results are better, BUT, when the wheel speed gets above a certain point the brakes still don't work! I think its just a poor design that does not work at speed. It seems it just not possible to get enough voltage to the brakes to overcome the centrifugal force affecting the pads.

Im thinking about putting some material behind those metal pieces to keep them constantly rubbing the brakes and that way minimizing the gap between magnet. Maybe it will hold a little bit better that way.. totally useless desing as it is now.

is this the version that doesn't work? I put a 3s lipo directly to the brake no radio or controller (momentarily). With no wheel I can still turn that metal plate by hand. With the wheel on I can torn it by hand. It seem some others have the opposite issue where the brakes lock up too easily??
it's like there is not enough friction between the plate and the rubber. I'm trying to figure out what I can do to that plate to give more friction. I tried to ca some sand paper onto it but it made it slicker.
help!

So here’s my JP retract and brake controller, Well the brakes have already quit working, I was still setting plane up when they had puff of smoke come out of them ? The retracts still work fine so my question is what’s best options to get brakes working. Xicoy brake controller, or complete xicoy retact and brake controller??

Even though my JP controller is working fine right now, I have a Xicoy LG-15 controller on order. JP's quality is too questionable, especially for the expensive jets arena.
