Building a Renger "Ringer"
« on: January 22, 2010, 03:06:25 PM »
I have just started building a 1/2 A size plane a la Larry Rengers scale downs of larger CL planes. My project is a 60% scale down of the Fancy Pants. But the project is a "ringer" plane BECAUSE:

1. Is wasnt built by Larry
2. It goes around a ring just like Larrys planes BUT:
3. It uses an outrunner electric motor
4. It uses a Baby Clown kit wing panel as a starting point.
5. It will use RC control of both throttle and flaps/elevator ( I just cant spin around fast enough anymore).
I have just completed the wing and flaps, here are the pics of the original Fancy Pants and my completed wing.

Sounds interesting.  What power system are you using?

I have posted the power system for my Baby Clown on the electric forum. This will use the same:
BP Hobbies (Suppo) 2212-13 outrunner motor (kv=1000)
APC 8x8 prop
BP Hobbies (Suppo) 20 amp helicopter speed control in governor mode
3S 850mah Hyperion battery - will be inside the fuse.
Timer replaced by rc throttle control

So it's a Tether plane? Fxed pole in the circle?

I tried a center tether plane once.  It takes some real getting used to.  Start as slow and low as you can until you get used to the quickly reversing directions.  Bob Davis, of Davis Diesel proposed this system years ago, diesel powered, of course.  There is a bunch of agitation going on in scale and carrier to allow the use of r/c controls now that sub-miniature 2.4 GH equipment is readily available.

Not intending to go off on a tangent discussion but, RSM Dist. sells a manually controlled tethered system whereas you sit outside the circle and fly the plane normally with a handle/ wires going to the tether pole. Micro R/C would be another way.

Nobody should have to give up this hobby due to age or inner ear problems (balance).

I agree with all my heart but...

In this case I feel that Jim is Not wanting to fly R/C but trying his best to continue participating in a hobby that he loves by using what he knows to do the best he can with what he has and continue to fly and not hang up his wings just yet.

I may be in the same boat soon due to physical limitations.

I "cut the string" 10 years ago when I gave up on CL. But I have missed it ever since. Three years ago  I reattached the string and started doing RC/CL and I really enjoy it. I like it more than "free fight" RC.

I like to promote it because it is a  possible way to attract more RC pilots into CL. And finally with electrics I can do it all day in my back yard if it isnt too windy! #^ #^ #^

Click on this image and you wil see a short video of the RC/CL that I fly. Its 90% Cl and only 10% RC.

Just watched the video and I liked it.  It would be great for those that can't get past the dizzyness or have balance control.  With the new radios it is a great idea as it could get Cunningham flying again as well as a few others.  Of course high or gusty winds might be a problem.  So it is not true control line it is still flying.  R%%%%

Heck I flew "round the pole" electrics in the 70's with a big old train transformer driving power down about 8 foot of copper wire to a radio shack motor.    It wasnt quite  control line either but it was still fun... and something that could be done in the park department meeting room we used in the winter.    Now we are all too busy BSing here to do silly things like that.

Renger "Ringer" - Partially Completed!
« Reply #11 on: February 18, 2010, 10:44:10 AM »
The pictures below show the top and bottom views of the partially completed fuselage and tail feathers. They also show the layout for the electric flight system. The electric components are described on the Amped up page, List Your Setup, as the Baby Clown system.  The battery is blue and the governor esc yellow. I included a tag in the bottom picture showing where the timer would be. Hopefully this plane will come out lighter than the Baby Clown which weighs 10.5 oz. The sides of fuse are 1/16 balsa, top and bottom will be 1/32 balsa. Reinforcement of 1/64 ply. I am now waiting for a canopy.

Larry

I am in the middle of finishing the fuse. The front deck and canopy are installed but the curved-top rear fuse part stumped me. Finally I decided on styrofoam formers covered with plain paper. 1/32" sheeet just wouldn't take the sharp bend required. This construction is a little unusual but was the best solution I could come up with. I hope to show pics of the completed fuse soon.

I have used styrofoam with ladies nylon stocking material laid over it with white glue.  Pretty tough and light!  Dead stockings easy to come by if you are married (or gay?)

Renger "Ringer" almost done
« Reply #16 on: May 02, 2010, 08:23:15 AM »
Here is a pic of the almost completed fuse. The hard part of its construction was the canopy and the after deck. The canopy is a cut down Sig/Brodak SC005. The front part of the aft deck is ink-jet paper over 3 Styrofoam formers and all Styrofoam at the rear. When the plane is completed I will start a new thread on the final covering and assembly.

Jim, 1/32" soft balsa sheet, thoroughly watersoaked, would take that afterdeck curve.

Thanks for the info. Having no experience with such tight bends I opted for the paper. I dont consider myself an experienced builder.
