Discovered that the local indoor electric group is flying 18" x 18" PBFs in Springfield, Mo. and doing combat some.
I Don't fly with 'em do to a condition of "Chronic Employment" but I had to smile about the PBF proliferation

Hi Dave!
I know what you mean about "chronic employment" interfering with having fun.

One of these days I'll get around to trying an electric PBF.

Hey guys,

A club member let me fly his at a winter fly a few weeks back and I fell in love with it. The more I thought about it the more I wanted one. This last Sunday at work I found the sign in the dumpster so I took it and built one in two days with extras that I had laying around in my shop. So it didn’t cost me a dime. Was going to fly it tonight after work but had to work late. Oh well maybe tomorrow. I'll post som picks whin i find out how.

Hmmmm, I know that club member[8D][8D]. Seriously, charlesp did a great job of flying my PBF and he also did a great job building his. It looks great! I can't wait to hear the flight report. We are supposed to have high 30's today and low winds. Also looking forward to when we can fly them together.



(Can you tell that I'm just a little excited to have another PBF in my club)

Congratulations Charlesp!

Flying a PBF is fun. [8D]

But flying a PBF with your buddy who also flys a PBF is LOTS more fun!

Congratulations to Goingstraightup on spreading the PBF Virus up there! [sm=thumbs_up.gif]

(hmmmm.....I wonder what ever happened to that old "PBF Virus" thread?)

Had about 8 flights today. The motor died 1 time and i thought it was done. It went straight down into the snow. lol i looked at it, nothing broke. I filled it up and went back up. I broke a prop on the next flight but that was it. By the time i was done i wes gettint about 10 feet frome me with it, and did my first Hairier. No way i would try that with one of my other planes!!! Ill have to order some new props as im using a 10x6.

my set up is OS LA40 (getting some 9x4 props soon)
rudder Hitec Hs 325
alerons Hitec HS425x2
and a micro servo for the thr.

Congratulations on your first harrier pass!

I'd also suggest swapping out that 10x6 for a Master Airscrew 10x4 or 11x4. The 9x4 is really too small for a 40LA.

Both the 10 and 11 will hover equally well.

The 11 has a slower and smoother feeling on the throttle, which makes the PBF feel more stable.

The 10 has a quick and crisp throttle response feeling, which will be more and more desirable as you get better and better at making sudden directional changes with the PBF.

CharlesP and me flew our PBF's for 3 1/2 hours today!! We had 31 degrees, light snow and ZERO wind. What a total blast flying in an old pasture behind CharlesP's house. We were tree trimming, tail tapping a shed - lots of typical PBF Fun. I also flew my Mojo 25 and I flew my PBF until my RX batt was dead. Did a nice spiral into the snow when the RX batt died. He loves the 10-4 prop. What a great day!!

Well, I had all the materials, servos, ect lying around as well as an OS40FP that is basically new, so I built a PBF. Its 24 wide by 23.5 long weighs 2lbs 7oz and is now my new favorite plane!! The first two flights were in insane wind of 15-20kts and it flew, but it was a huge hand full. Today I put in 3 more flights and already am comfortable enough to be trying to drag the tail on the ground in a hover. I love this thing. Super durable also as I got it into a mind boggling spin from 40ft up that I couldnt seem to recover from causing a nose straight down crash onto concrete. The only damage was a broken prop and spinner. Does anyone know how to recover from a crazy spin like that?

Never mind, I just did a search and read the spin recovery section on the website. I will try them the next time out.

Hi Dave: bet you never thought the PBF would last this long. My first one way back then and had an OS 25FP on it and you couldn't kill that thing. Still flying an electric one with a Blue Wonder and HXT servos from HK. Can even get it to do the Death Spiral if I nurse it into it. Hope you other guys realize it but Dave was the originator of the PBF. Much to be thankfull for.

Flypaper 2, thanks for the kind words! You're right, I never would have dreamed that the PBF thread I started about 8 years ago would still be active.

Even after 8 years, I still enjoy flying a PBF. For those who haven't flown a PBF before, here's a video to give you an idea of the fun you've been missing.

Default RE: PBF Pic. 2

Dear Dave McDonald,



I built my first PBF about 8 years ago.

http://www.rcuniverse.com/forum/m_19.../tm.htm#191796

I was very very very! happy when I flew it for the first time and I think it was one of the best days in my life. I am now very glad to see your replies here and every time I read them I feel happy . You are very kind and helpful. I am now about 45 years old but every time I fly my PBF I feel I am as young as my 12 yo son who is very interested in model airplanes too. PBF flying really makes me happy.

Bless your heart !

I am very sorry I can't describe my feeling well in English and sorry for any misspelled and grammatical mistakes.


Thank you so so so much!!!

mjse

mjse,
Thank you for letting me know how much you've enjoyed your PBF for the past 8 years! And I'm really glad to hear that your son is now interested in flying RC planes too!

Your english is very good! It's even much better than some people who were born and live here in the USA. So you have no reason to apologize for your writing skills!

Dave,
Another PBF that joined the Global Pizza Box fleet.See pic of my electric one (35" x 35"), It is elegantly simple in design and I was amazed at how well it flew.
Keep up the good work!

Cheers

Default RE: Flying Pepsi logo

Hi Mike,
This is a loooooong shot in the dark as your message I'm referring was posted in 2002. On that "round Pepsi" PBF, where did you put the CG?
I was building something similar when I came accross your posting with the Pepsi flying disk.

Regards


Johann

ORIGINAL: YLF

Here is a pic of my new flying Pepsi logo. Built just like a PBF but is 28.5" diameter. It doesn't fly as well as my PBF, not as good of elevon responsiveness and a bit less stable, but looks good in the air.

Mike

Bundubasher, nice looking electric PBF!

I'm not Mike, but the round wing planes I've made flew best with the CG at the 25% mark.

Dave, Thanks for the info. I saw in that 2002 posting that the disc was a little hard to fly - a possible solution on making the ele-vons/vators more slanted ason the attached pic ofthe Arup - but extend it all the way from the centre to where the aileron ends. It increases the area and distance fromcentre. Will let you knowhow it goes - oh, anotherPBF is under constuction,this one will be scaled to take a 46 Irvine - I just love these planes, they fly different but it is such fun. Has anybody tried to slope soar with a profiled one?

Cheers
