Interesting idea Jim....Don't have any friends..I outlasted them all! Smile I think I can get my sister to launch,..she's semi interested in my planes and is ex Navy. She videoed some of my RC flights...No place flat enough to take off from the ground anyway! We'll have to sacrifice part of a hayfield to fly!

Mr. Steve,

I keep runner mats in the trunk of my car to make an impromptu runway. The same can be done with corrugated cardboard/plastic, sections of light plywood or anything else you care to haul to your flying "field."

You mentioned enlisting a family member (and training how) to hand-launch for you. Look here on the forum for the "barstool and carpet" stooge. Or maybe the guys that have them will pipe up (ISTR Roddie or Rusty?).

If you can manage the wheel-less launch, then this is yours...all yours! Just claim it and it will arrive in one piece. It was my first plane returning to the hobby in 2016. Now it can be YOURS!

The firewall is drilled out for #2 wood screws in a Babe Bee pattern. You may want to fill the holes with some Elmer's Glue to reinforce them. They haven't pulled out...yet.
Run the engine vertically to protect the needle.
The solid lead-outs are not very stiff, so you don't want to cartwheel.
It has been shown here before. Look for my post regarding the Wido Satan (plans on FlyingLines.org)
It will fly a Black Widow or Golden Bee, but it really winds up nose heavy. I bet it will float along just fine on one of your Bees. I believe I have your physical address from an earlier post, either here or on RCG.
It has crashed, and been fixed. It is still a good flyer. If you get to fly it only a few times, and then dies...well, it did exactly what it was built for!

Jim,

That was very nice of you - to donate that ready to fly airplane! Clapping

I think I gave you a Greenie, but suspect I gave it to Steve (OhBee) first, before I figured what I was doing!

Who me, read directions?

On another topic, has anyone here used Spectra lines for lead outs? I flew all of my small planes on Spectra lines, but the thought just occurred to me that it would make killer lead outs as well.

Well, Mr. Bill, I do seem to remember you gave me a spare Norvel .061 muffler for my AP-powered Scientific P-40 (Rest-in-Pieces, dear WarHawk) a few years back! And FredVon graciously popped a UKIE .35 my way after the P-40 augered in...so what comes around, goes around!

If my kids won't have any of this, I may as well share with my dizzy airplane buddies.

I'm trying, Mr. Fred! Very Happy

Mr. Bill,

I used Spectra for lead-outs on a model with an external control system. Good thing the system was not In-the-Plane.

One of the lines chafed on a poorly finished line guide hole. Had the lead-outs been solid, the hole would have been burnished smooth. Had the lead-outs been stranded, the hole would have been worn smooth.

Then the knot slipped on the replacent line. Again, good thing the system was external.

In a nutshell, no synthetic lead-outs for me! I understand that won't fix bad knots, but at least the fail point won't be in/on the aircraft.

This is an update on 944_Jims widow satan offer. I have recieved the plane! Havn't seen one of these in the flesh since 1966! Now I have something to fly!...I hope! Thank you so much again for this Jim! And thanks to everyone else also for all the tips and help offered! My attempts at building something have been put on hold due to unforseen circumstances....so now I at least can attempt to see if this is possible again! I can,t seem to make the pics work today....

I Like that! Have your Sis hand-launch.. or use the "Triple-B" (barstool/bathmat/brick) stooge-launch system! (pokes Rusty..Wink )

Hi Jim,

Thanks for the reply r.e. Spectra lead outs. Sorry, almost missed seeing your comment, thus this late reply.

I've always been careful to de-burr brass or Nylon lead out guides. Gave up on solid lead outs after their first use on an airplane of mine and have used braided steel ever since. Got tired of trying to straighten solids every time they bumped against something.

All the half-A flyers in my club have been using Spectra lines for many years, with only two reported problems. One tried to lock his knots with CA and created a stress point and/or sharp edge to cut his line. The other fellow got Castor fuel exhaust on his hands and lines before doing the knots and naturally one slipped under load.

Also gave you a well deserved Greenie, for your generous gift to OhBee. Way to go, my  friend!

OhBee,

I was worries about shipping it, and so glad it made it. Remember, if it dies after only two flights, it did what it was sent to do. Have fun with it.

It looks good from here! I would drop the prop to 5x3 since it is on a Babe Bee. Of course, if this prop is all you have, then run it!

CG 1" back...I seem to remember the Golden Bee put the CG right about on the LE...so you should have a smooth flier there. Watch the wood screws on the engine mount. If they have an unthreaded shank, then they can sink threads deeper into the nose block but leave only the shank in the plywood. They will grab only balsa (not good).

If they are threaded all the way to the head, then there will be threads in the plywood (better holding power).

You asked about mixing that dope. The stuff I sent is old school..It may not mix well with other dope wet (in liquid form), but it should be alright for patching over previously cured dope. Most of that plane was doped a few years back. The two patches closest to center on the trailing edge were done just about 10 days ago.

You did determine which of the tissues is DocSpan (exam table paper) and which is cheap gift wrap, right? The gift wrap is for patching the Wido Satan. I found the second plastic wrap here. Apparently I dropped it back out while building the box.

I hope you get to enjoy it. My kids couldn't care less, so it is in a better place now!

Thanks again Jim!..ya..I know which screws ..I actually have 2!  Will search for more!  You marked the grain direction on the "docspan"....frankly I cant see any diff one way or 'tother! Does it matter?.Which way is the "grain " supposed to run?.......and I plan on flying it WAY more than twice!  You should have seen the wrecks I repaired on my original back in the 60's!...  I think I have a 5x3 prop. What will the dfference bee?  Just more rpms isn't it?....less speed?
                  Just checked...the 5x3 I have is square tipped....no good?
