I wrote about the braking issue a couple weeks back, well, my braking did not get better with the time, so I contacted Erwin from Airtech last night explainig him my problem, his reply was that O-Ring brakes dont work well with proportional brake valves, I'm usisng the JetTronics that comes with the LG Set, so I will have to change it to just On Off bracking as he suggested, in case someone else is using the same there is the answer to the braking problems.... Will try that next weekend....
Hey that looks cool. I like it. you can see it good.
I like the BVM proportional the best but I using the up3 this time because I had one a new in the box laying around for another jet.
I had a lot of issues with brakes on my first one till I figured out the air was leaking at the wheels. You can test it by hooking directly to the wheel. What I found was to make sure the backing plate (the part with the Oring) is seated all the way in to the rim. It appears to be slightly beveled. I had to use a spacer on the hubcap side to up the axle bolt slack out of it. I guess you could shorten the bolt or thread the gear all the way thru to prevent the bolt from bottoming out.
If you find you have to do that you will notice the hub cab will not seat without rubbing the head of the axle bolt. The easy fix for that is put a Oring where the hubcap screws in so it will stop before touching the bolt. The Oring will keep the hub cap from backing off. Ask me how I know
Mine has good braking now. I know I on my first one I could lock them using the BVM. It did seem to get better over time because the Orings will flatten out from use and make better contact.
