Thank you Rene!!!!!!!!!
Tonight I sprayed some grey-primer on the newly reworked wingtips, outdoors on the back-porch (deck)..
Tonight's photo has a very "blue hue" to it..
... which inspires me to spray some black paint judiciously.. and name the model "Blue on Black".. a song by the Kenny Wayne Sheppard band..
click here..
I want to give this model a theme.. but at the same time; keep it stealthy.. like a night-fighter/interceptor.

Re: P-38 Lightning-Roddie style..
I read "exhibition" which probably means static. But could also mean let 'er rip Roddie...…..it's only balsa.
Good luck in either case.

Re: P-38 Lightning-Roddie style..
anybody have any luck finding these?roddie wrote:I have voiced my opinion on the usefulness of the 1/2A spring-style wheel-retainers before. Carl Goldberg models and Sig Manufacturing "had" offered these in the past.. but now; unfortunately.. you'll need to hunt for them. Bernie (Cox International) had sourced a NOS supply of them not too long ago.. and may still have some packages.
Hear me out.. these spring-collars are designed to fit 1/16" (.062"/1.6mm) piano-wire.. and provide a lightweight/reliable friction-collar that will assist in a myriad of modelling needs.
I am using these with this P-38 model. The elevator-pushrod is 1/16" piano-wire. It utilizes two "L-bends" which must be retained. Using a series of flat-washers with a spring-retainer; a linkage can be made to work with reasonable precision.
These photos will show where I have used these spring-retainers in the control-linkage of this model.
The above photo-example shows a 1/16" piano-wire pushrod being retained in a Sig 1/2A Nylon bellcrank. Take a close look..
The spring-retainer establishes a "clearance". That's basically the beauty of using it.
Here is where I use one on the elevator horn...
I'm just a novice flyer.. but I like to build precision into my flying models. It doesn't cost much...

Hi Joe! Sorry I missed this/your inquiry. My forum attendance has been sketchy these last few months. Short answer; "NO".. I haven't been able to source them.
You "can" make them from .015" music wire. Be sure to wear safety-glasses when working with music-wire. The original spring material is between .017" and .020" depending on the supplier. (Sig and Goldberg were two suppliers of these)
I had some .015" music wire in my stock.. which I "hand-wound" around the shank of a #54 drill (.055" dia.) You could try a #53 drill (.0595" dia.) but the coil won't fit as tightly around a 1/16" dia. (.062") music-wire axle-shaft.. as the purpose-made parts do.
Here's a coil of .015" dia. music-wire which I wound in excess. You'd only need 5-6 turns to make one retainer. I would suggest making one at a time.
Remember.. Be sure to wear safety-glasses when working with music-wire.

Thanks Eric. The first link's seller has X4 packages containing X6 retainers each for $17 plus $3 S & H. Seeing that he has X100 packages, maybe he'd do a better deal if someone bought X10 or more.
Re: P-38 Lightning-Roddie style..
I would think so roddie if he still has them ? The second one has other stuff too and 2 packages of the retainers for 21.99 free ship so not bad . Hope @akjgardner will see this .
