Seems to adhere just fine. I first started with the "Testors" style model paints, thinning it a little with water. I found it was difficult to obtain the right consistency though. Either too much water and the air brush just got the foam wet, or not enough water and it comes out all clumpy and stuff. So I moved to the air brush paints which are already mixed for the proper consistency of air brush work. But other than that, I haven't had any problems.
BTW, I've gotten "supposed" delivery attempts also while I'm at home. No knock on the door, no ring of the doorbell.
Ain't the mail system great?!?!
Oh, I've got my servos. Futaba S3108's. Tomorrow I get the plane, motor, and receiver. And tuesday I'll be getting the lipo pack. Waiting on the esc, which is on backorder at the moment. But should be back in stock by the weekend. I'll try not to clog up your thread with stuff about my extra though.
Once I start working on it, I'll make a build thread for mine.
