Thanks for the kind comments gang.....now if I can just get Brad to drop in to the cedar mill one day, and scrounge me up a couple three more "blanks " we can do some more props..like for a certain D V11 that's gonna be flying again soon :-)..and my EV needs one too.... and so will the next "secret" project...spent three hours today...with numerous timeouts for coffee, smoke, lunch etc....prop is carved totally...pics in the morning with a running commentary. oh..balanced too...and this time no power tools..all by hand..I tried it out already.......it's just the right size to spank the grand kids with :-) works good...hope it works as well as a propellor :-)

I'm eagerly awaiting pictures of the prop.

Just curious, you said it is cedar, any idea what the real props were made with? Were they cedar as well? I'm sure different countries used a couple of different woods depending on what they had and what they could get.

I am humbled by all the master craftsmen on this forum.
I need to learn how to fly my planes with paper bags over them.;-)

79 CJ... I actually said it's YELLOW cedar ( cypress to some of you) but I think they used whatever was straight grained, and knot free...... material type likely wasn't that important......remember the average life span of a plane wasn't very long :{
So any way in the first picture you can see the bench leg that I was convinced a 28 X 14 prop was hiding inside of. next two pictures you can see the layout that comes from the couple of simple calculations I described earlier...now in the next one, we have rounded up all the necessary tools,a steel rule, a square, a set of dividers, a spoke shave, and some sand paper...time to make some wood chips ;) next is a picture of the stuff that doesn't look like a 28 X 14 prop..then finally I found it..the prop that was hiding in the table leg :D now all I need do is stain it, put it on the model and see if it works as well as a propellor, as it does to club fish :p> the whole process by hand took about 3 hours...if you have a disc sander( angle sander angle grinder) with a flexible sandpaper disc mounted on it this whole thing can be carved likely in about 15 minutes, but I wanted to do it without that luxury just to prove you don't need any special tools to make a prop.. a ruler, a spoke shave or a knife and some sand paper..just as an experiment this morning I carved a 10" prop with a razor knife in about 15 minutes...guess who's not going to be buying many props from now on ? :eek:
db..I usually fly mine with a grbage bag 'inside" them...then..that way I have something to put all the pieces in when I crash

Thats why I fly foam planes, they break into larger pieces than balsa planes when I land. I can not tell the differance between my landings and a crash. They say any landing you can walk away from is a good landing, I walk from all my landings so they must be good.

dbcisco 01-22-2010 06:47 PM

Any landing that a mouse in the cockpit would have survived is a good RC landing. Fortunately mice are quite resilient.

Ron 01-22-2010 07:17 PM

any landing you could walk away from or that keeps the plane in one piece is a good one...any landing that leaves the model so that you can actually fly it again (without fixing it) is a perfect one :-)

Ryan Flyer 01-22-2010 08:33 PM

How 'bout any landing you dont need to walk TO is a good landing.????:ws:

Does that include the one that hit my wife?

Ryan Flyer 01-23-2010 01:17 PM

If she walked away then thats where you use "any landing you can walk a way from....":D

degreen60 01-23-2010 02:52 PM

She walked but I run.

Ryan Flyer 01-23-2010 03:08 PM

Ok That must be a bad landing if the pilot ran;)

Ron 01-23-2010 09:28 PM

Well today was bench test try out time for the DR1....I programmed the speed control, and installed the prop..hooked up the battery and tied the model to my digital scale so that I could check amps, pull, and RPM.....

the amps was about 40 I think when I aborted the test....I did find out though, that the wing tip skids work :rolleyes: at about half throttle, the model rolled to the port side and the wing tip skid was on the ground..then both wheels came off the ground...didn't have the moxy to check the pull or the RPM...before I killed the throttle, :red: but from the looks of it there 's gonna be lotsa power::o I have never before witnessed a model's wheels coming off the ground while it's tail is tied to a post...SHEESH ! ::o :ws:..first time for everything eh?
Now we're finally ready for test frights :Q

Great link! Some cool pictures on there and a lot I have never seen before.

Ryan Flyer 01-26-2010 01:27 PM

Hay everyone, I am really exited this morning, I finished building and taxied my first WW1 airplane! still a few things to do before the maiden but it is mostly complete. I is a Avro 504k That I built for foam using plan from Debreen. Thank you De!
Anyway I think it will fly nicely if I can get the CG righrt so wish me luck on the maiden!

Congrats! Post up some pics for us to enjoy :)

Ron 01-26-2010 05:14 PM

Patrick good luck on the maiden...how about a picture or two??

Did you just use the printed plane as an outline to cut the foam or did you attach the printed paper to the foam so you did not have to paint the plane?

Ryan Flyer 01-26-2010 08:02 PM

I painted it because the copy machine I used to enlarge the plans would only do BW. I need to ask K Close to help me with the pictures, I dont know how to do it yet. But it will be soon.
Thanks a lot,
Patrick

I aways make a BW first on my printer even if I am going to use a color print for the plane. I only have a BW laser so I use it to make sure I have everything correct before I have son print me the color copy. A couple of my planes were made using BW copy then covered with color print. I just made some emblems to go on a plane using my BW printer then colored them using marking pens. You can use BW to get panel lines and such then color with pens and the lines will show through. Are you and Kclose going to have WW1 dog fights? Looking forward to seeing the pictures.

So I took the Avro out this evening. I had been windy all day but it was finelly calm so I threw it. I had had a hard time getting the cg right and had to add a lot of clay to the nose. Anyway It flew! It was still tall heavy so it was hard to controle and because I had the add somuch clay to the nose it did not climb well and I thought it might not make it over the trees so I chopped the throttel but this was a mistake and it did not glid and hit the ground at about a 45 degree angel. It was not to badly hurt so I just need to get the cg right and it should fly good.

Thanks for all the help every one,
Patrick

Nice thing about WW1 foam planes they fly slow and bounce when hitting things(including my wife). They break into large pieces and easy to fix. I always try to mount everything as close to the fire wall as possable. I use pull-pull string for control to keep the tail light.

Ryan Flyer 01-27-2010 10:58 PM

The avro did not really brake the wings just came off and the prop broke.
Pull pull would be a good idea but it is harder the build. I made lighter push rods but I still think I am going to have to do more to get the CG right. Anyway it is almost fixed so I will have more updates soon.

Patrick

K CLOSE 01-28-2010 04:43 AM

Pat, you should have called me, I would have tossed her for you ( I'm off today-yea) I'll call tomorrow and see if I can't help with the cg and get your parts order.
Cheers, K
PS. Riley's Camel is comeing along well.
