Hi Dave,

I'm using the PhaseIV version of the CompactUniBrakes available from here: http://www.compactunibrake.com/ .

I bought mine from Don's Hobby Shop ( www.donshobbyshop.com ) but called them directly to make sure it was the PhaseIV style. Don had them to me in a couple of days. Very nice folks to deal with. Reason I went with this vesion is that I could bolt them right on the 3/16" strut and they took up minimal space when used with the 3" Robart wheels. The Robart tires are a little soft for a 17+ pound airplane so as suggested earlier I did get the tire inserts and installed them inside the tire. Made a world of difference and anticipate no problems with them. Keep in mind that you'll still have to order an additional air tank, tee fitting and plumbing to go along with the brake set. If your were gutsy I guess you could use the same tank as your retracts, but I didn't want to take a chance with a leaky valve or line connection and have it deplete my air for getting the gear down. Hadn't got it installed yet but when I do I'll post pictures for everyone. You'll also will have to get a brake valve and will require an additional servo to operate it. Makes for some interesting engineering work to get it all installed, but I've solved that too. Minor deviation from Bruce's setup but it's all good. I got my brake valve from www.dreamworksrc.com. Give me a day or two and I'll have some pictures for you. Just about wrapping up my Monokote work. It took longer then I had anticipated but the finished look is worth it...

Cheers,
