Bringing this thread back to life to ask for some assistance...................
I recently purchased this Freewing 90mm Yak 130 ARF+. I installed the 8s Freewing 12-bl. fan with 4075 1390Kv Inrunner Motor, coupled with the FMS 120A HV ESC (which I already had). I've flown this plane several times now and it has become my favorite jet. Till now, the Freewing L-39 was my fave. It's got enough grunt to make this plane what it should have been all along. The old 6s Yak 90mm that my friend had years ago was a real pig - underpowered, overweight, too draggy. The 8s system more than compensates for the weight and dragginess. It blasts down the runway with authority and lifts off without touching the sticks after a fairly short roll. And those landing lights ......................... man, are they BRIGHT! Everyone commented on them. With a HobbyEagle A3-L and Assan steering gyro, this thing tracks like an arrow and is so locked in. Landing with full flaps has been picture perfect each and every time. It'll do a large loop from level flight without a problem, unlike the old 6s, that needed a good diving start for a loop and even then, it was likely to fall out before getting to the top.
Now to my actual topic ................................... Because it's an ARF, the top airbrake is sealed and I have no idea how to make it operational. I don't want to slice it open and pry it up in case that's the wrong approach. There seems to be a hatch just forward of the top light that has a seam around it. I could open that up to see what's in there that might give me a clue as to how the thing works. The airbrake probably doesn't do much, but like my SU-30, it looks real cool and I'd like to make it work. Does anyone have this Yak with a working airbrake? Can you tell me what the mechanism (servo/actuator/rod) looks like? A picture of the airbrake open and looking into the cavity would be helpful. Thanks.
