Whatever you want to call it, here's a web page I created with enough info to build one of these cool flying wings for yourself.....without having to wade through literally hundreds of posts on RCU.

If you like fun fly planes, you NEED a PBF!

Please note that I'm still constructing this page, so at times it may look really screwy.

Constructive comments welcomed!

Have you looked at those Flippin' disks?? They're the ones with the pvc fuse and round disk type wing with a little airfoil worked into it...

I flew with a few from Arkansa and boy did I get my hat handed to me.... They totally outflew me.... Maybe it was just pilot... but that little plane really seamed to out manuver my pbf....

Thanks for the compliment!

I've seen the Flippin' Disk here on RCU, but not in real life. I would love to get my thumbs on one to see how it compares to the PBF!

Status: offline 		Dave,

I was wondering... I have some mini stuff, meaning Hitec 555 RX, and four HS-81 servo's. The 81's have almost as much torque as a standard servo, but are about the 1/3 the weight. Plus they are just sitting around taking up space Would these be strong enough to run the elevons plus the rudder?

Thanks,
KsFlyer

Also I was wanting to say that I don't have one of these planes..... "yet.'' But if they just tool around flying slowly then I'm quite positive that the hs-81 will work wonderfully.

Mini servos will work fine on a PBF. My first PBF used Futaba S-133 servos all around, and they are only rated at 27 oz/in of torque. The S-133 had fairly weak geartrains, but I haven't stripped one on a PBF yet.

My third generation PBF is is flying with with a TT 42GP and a MCP and uses Futaba S-132H for elevons and rudder. They're only rated at 25 oz/in of torque, but they work just fine.

I hate you. I have been doing this forever. I have built plane after plane, searching for just the right combination. Last week I found the other, longer, thread on the PBF. Do you know how long it takes to read that sucker? Now you reduce it to something that can be read in a few minutes. Of course, you did this after I completed my PBF.

I can't remember the last time I had this much fun. I am sure there will be several PBF's at the field shortly. The laughing and fun never seemed to stop. I had to put some wheels on along with a skid (we gots a paved runway surrounded by packed dirts). The thing took off in about 3 ft. The gear and skid added about 2 oz. I have an old OS 25 I stuck on it, along with a couple of $6 Cirrus servos. The thing seems wildly overpowered with the 25. How the heck do you control one with a .40 stuck on it. LOL. Never mind, that's for me to figure out next week. God, what a great plane!

Anyway, to you and FoamGuy.... Thanks

Status: offline 		I was wanting ask you Pizza box guys, how do you land. We were arguing about this last night at the field. I just assumed like any combat like plane, you would simply cut the power and coast it to the ground. However, a couple guys told me that it would fall out of the sky once power was cut. Do you guys glide them in or do you hover them in low and just let them fall.

Second question, does the heat make your coroplast get kind of saggy? After setting my PBF in the back of the truck yesterday, the sides were sagging because of the 1/2" brace in the middle.

Please advise.
