RE: Pay it forward (Was freebie and fee engine)
RCKen, was just wondering how the covering has been going. I saw the pictures of the wing but haven't seen any pictures of the finished product. You guys still making headway on the build or just really busy with other stuff?
The build thread is really awesome though, nice work!!!

Just been busy. I'm hoping to get back to the write up this afternoon. I actually get to work out of the house today, so as soon as I can get some other stuff wrapped up I can get to work on the build thread.

RE: Pay it forward (Was freebie and fee engine)
Hey guys, this thing you're doing sounds great. If I wasn't a poor college student and actually had stuff lying around, this would be the first place I'd go.
This is more of a request, because I could seriously use some information/advice.
I'm an ARO (aerospace engineering) majoring freshman at Cal Poly Pomona and on a whim decided to join a Design-Build-Fly club at my school where we :ahem: design, then build, and then fly a plane in a competition hosted by the AAIA. Since it turned out that I had the most experience with electric motors (from my experience with ground-hugging vehicles) the whole matter of propulsion for our plane has dropped into my lap. This includes what electric motor to use, which batteries and yes, prop choice.
This year's competition requires a huge, heavy plane to be powered by a max of 3lbs of batteries and by a motor that is limited by a 40amp fuse. :O
The most difficult mission we're going to fly requires us to load two 4.4lb water bottles, fly around a short 2000ft course, land, load another water bottle, fly a lap. land, load another bottle and so on to 5 water bottles for max points. That’s 22 lbs of water. We figure our design (a high-wing dual boom looking thing, looks exactly like the plane from Flight of the Phoenix) is going to weight about 8 lbs. Add water to that and you get 30lbs max. The design currently has a 9.5 ft wingspan.
We can't use LiPoly's either.
I'm seriously not sure what motor, batteries or prop i should go with. Since were not caring at all about speed, I guess a huge propeller would be good, The fuselage’s diameter is going to be about a foot n a half. With landing gear figured in, we should have clearance for one monster of a prop.
With something that large, using an electric motor would probably require gear reduction? Maybe? Is it possible to create about 7lbs of thrust (what the seniors say we'll need) with a 40 amp limit and around a 26 volt limit? (I get 26 volts from being limited to 3lbs of batteries, which means a max of 24-26 Sc cells).
I'm sorry I don't have an actual straight foreword question, I'm just digging for any information. Any ideas and or suggestions would be greatly appreciated. Basically, I'm looking for somewhere to start at, to start experimenting with.
Thanks a lot!

I think you might have have better luck posting this in the electrics forum. It sounds to me like your question is how to provide enough power to fly this thing using an electric motor with the limitations you stated. The guys that are heavy into electrics will know better how to create the kind of thust to weight ratio you're looking for. Good luck with your project.

I'm still thinking on how I'm going to pack it up and ship it to him. I'm working on getting that worked out. Hopefully you've noticed that I'm back to writing up the build thread on that project.
I'll keep you posted

Mark,
You bet. I've been a bit slowed down for the last 2 days. I've had a "twinge" in my back (was bending down to pick up a pencil
) and between that and the pain meds I haven't got too much done really. I'll let you know as soon as the other thing is on it's way out of here.

No problem, I know all about the meds, been in slow-mow myself for awhile now.[8D]
By the way, don't you ever sleep? Do you know what time it is in OK right now? GO TO BED!!
Get some sleep.[sm=sleeping.gif]

Sleep?? What the heck is that??? Actually, I've got a Thermacare heat wrap on my back, and because of the heat I had trouble getting to sleep. So I decided to get up and get some work done instead of laying in bed sweating!!

I don't know if anyone here knows me all too well since I'm in the car forums more than the airplane forums (hey, I'm still a avid airplane guy), but what happened to this program? It seems like people gave and recieved and they all disappeared. I haven't visited this thread in a while, and noticed its not a Sticky at the top of the forum anymore; why is that? Also, http://www.rc-pif.com cannot be opened because it no longer exists on the hosting server.

I was able to open www.rc-pif.com with no problems. But yes, you are right in the fact that this has slacked up a bit. Thinks have been a bit crazy for Bill (Bubbagates) in the past few months. But I reckon as the flying season gets back into full swing we'll see the PIF pick back up.

Hmm...well, I tried http://www.rc-pif.com/ in Mozilla Firefox, Netscape 8.0, Internet Explorer, and Opera, but none of them could find the site. I also checked my Internet connection, and it seems to be working with no problems.

Bump--
If someone notices that the thread has slowed or briefly stopped, that simply means that person needs to dig deep and offer something!
It is not Bubba's or RCKen's job to keep it going it is ALL OF OURS!
Let's get that momentum back folks---

Anyone?
Bueller?
Anyone?
Okay- I have a few standard servos and an RX battery if someone needs it... Let me know, I also still have the magic-3D Airframe (Used but workable) maybe there is someone in the San Diego area for the airframe?
I also instruct for free in the San Diego area if anyone needs it-
Have a great night all!

Bump-
I was a benefactor of this site a while back and due to some major personal changes I have been unable to finish my plane. I hope to get back to it in the next few months. I hate to see so much inactivity in the pay-it-forward. I know there are tons of good people out there, y'all just need to speak up!!!
Until next time.....

RE: Pay it forward (Was freebie and fee engine)
One reason for the slow-down IMO is that the thread lost it's sticky status so it doesn't take long for it to drop off the front page. This was unavoidable and not Bubba's fault. If people will continue to keep making posts of ANY type (hopefully beneficial) it will keep the thread on the front page and visable. I doubt it will ever get returned to "sticky" though. Due to management policy and the simple fact that there is only just so much space on each page. I am not faulting management in this statement, decisions must be made.

RE: Pay it forward (Was freebie and fee engine)
This weekend I rekitted my plane due to a windgust. I will not be able to purchase a new plane in the near future. I was wandering if any of you guys who have stored your flight simulator in a shelve collecting dust would be willing to donate it so I can continue to practice while I can put another plane together? I hate to ask but I need it. Thanks!

ok,
i have a club, a have a plane (sig EP-42) and the motor is going to burn up soon.since i am youngish i need help with the new motor. the stock one is a super 400. im kinda tight on money since i had been saving for about 2 yeaqrs to buy the plane and a futaba radio and the whole nine yards extra everything just about. so...i was told by some one to go here and to see if there were any electric motors. can anyone help.
