I bought these grip hoping i could figure out a way to make them work on my Jumper TX16 Pro. The match is perfect, But the 3 pronges (what ever they're called, lol) are not long enough to reach the holes on the back of the radio. They fill so good when i hold them on the radio, but cant figure out a way to attach them. Oh well, it was worth trying. They fill so much better than the stock Jumper grips. I thank you anyways for a good product, maybe i will come up with a way to do it.
