Hey fellas, I was wondering if I could get some help. My Legend Models P-38 arrives this week and I'm anxious to find where I could get scale struts/wheels for it. I want it to look as scale as possible not unlike many of your YA and Ziroli P-38's do (someday!). The struts and tires that are offered are bland and definitely not scale. Any help is greatly appreciated!

The Legend P-38 is a re-entry for the old VQ 83" airframe. Spring Air made a Kit with 100 degree mains and steerable nosewheel, but you will have to come up with custom length struts and wheels for a true scale appearance.

Welcome to the brotherhood!
Xoar has those, links to Graves

Bella's got some in the Scimitar series, can look at Aircraft international, or TBM
Lets see some pictures!

I too like Spring Air's products, and would highly recommend giving them a call
On my 90" NP model, I used a 105 degree nose and 90 degree mains. They are Robart 635 series from a Topflite B-25, and you can find them pretty cheap! I used longer Robart 1/2 struts on the mains, 3/8 on the nose, 4.5" Hangar 9 mains with decal hubcaps, Robart 3.5 nose wheel. The wheel on the hangar 9 wheel was too big compared to full scale, so I had Callie print the black ring in the picture, and it looks fine. On the VQ, I think these may be too big, and I would look for something a little more narrow, maybe Dave Brown? Here a couple wheel "hubcap" pictures
I did a bit of surgery to get the retract pivot point up high, close to where full size is, and added wedge shims to get the struts to rake fwd. Not really scale, but overall a big improvement.
This was my low buck approach, and they are different planes, but hopefully info is helpful

Pretty clever use of decals! The gear looks way better that way you have it set up. Not sure why the Legend P-38 design went with such a bland gear arrangement on the model, after seeing the internal airframe photos on RCG I think the same can be done for it too.

Look what UPS dropped off yesterday evening for my 1/4 scale P-38
.
A pair of DA100 in line, one reversed.
18 new Futaba S-Bus servos, I am using the BLS172SV (514oz -.11sec) on all the flight controls, 2-elev, 2-rudder, 2-aileron and 4-flaps. I have standard S-bus on the engines and gear. The nose gear steering is a Car steering servo.
I have the canopy ready to pull some parts and will arrange that in the next week or so.

I feel like a little kid at Christmas! Tomorrow at the AMA expo I get my P-38,,, Cannot wait!!! The only thing better would be to win the drawing for the ride in a P-51!
Also check out Century Jet for retracts. They are making new 100 degree nose retracts and they are either air or electric. I have a set from an Art Johnson P38 and they were pretty sturdy,

Hi to all P-38 lovers. Hope I can be included in the brotherhood. This last summer I was able to buy two Royal P-38 kits from a friend in our club for 75 dollars. He had found them at a garage sale and when he offered to sell them to me, I jumped at the chance. The gentleman that had them before had started some of the wing and booms, so that's where I will pick up the task. This will be a little longer term projects since I've found this Royal kits are definitley " builders" kits. With all the info on this site I will probably be asking for some advice real soon. Thanks to you all in advance. John

Pull up
I forgot about Fiala props. I tried ordering direct with no luck, but Espirt is starting to stock them now. They have three blade pusher props, and a big selection of sizes and pitches
» Coming Soon Custom Wood Propellers from Fiala CZ
» Coming Soon 4-Stroke Gasoline Engines from Valach Motors CZ

Just back from the AMA show with the JB P-38. It was well packed and no damage. I like the silver finish more than the olive, but that is a personal preference. Great panel lines and it looks like it will be a fairly easy build if you have some experience. It is going to look good stock, but an individual builder can easily add additional detail. I have to wait a bit to start because of other projects (repairs!) on the bench, and the landing gear is in the next shipment which should arrive any day. James at JB was great to deal with and took a lot of time talking to me even though he had a LOT of people at his booth.

Thanks Mike, appreciate it! AI is in the middle of a move, really hoping that Biela does a scale pusher version!
I picked up a Silver JB P-38 at AMA and it looks really good. Biggest difference I see is that the new covering is printed film rather than the 'shelf-paper' style covering on the VQ. Should be much lighter airplane.
I also picked up an un-built Yellow P-38 Kit at AMA too, but it is missing instructions. Realize that it's 60+ pages, but if someone could scan and PM to me I would be forever in your debt!
Thank you P-38 Brotherhood!

Unfortunately 90% of the AMA show floor was UAV's and Drones. The planes I picked up were pre-arranged deals. There were some beautiful scale builds on tables around the perimeter, including 2 P-38's - a Yellow with a nice weathered silver finish (pictured) and a 120" Ziroli was for sale at $4500.
The Yellow had counter rotating props, but they were on the wrong sides...left engine ran anti-clockwise on the full-scale version.
Thanks for the Manuals Mike, If you ever get out to NorCal, I'll buy you dinner!

This is one area where it is probably prudent to deviate from scale. With the props rotating outboard as they do on the full size you have two critical engines in the event of an engine out. With the props rotating inboard, as they do on nearly every other airplane with counter rotating engines, the "live" motor is trying to lift the dead wing rather than forcing it down.

Chad,
True, The P-38 is somewhat unique in its engine rotation setup. Both engines are more critical than standard counter rotation setups, but both are still equally critical.
Short version from my Gleim MEL training books below. Historical note, Charles Lindbergh, during flight testing, actually came up with reversing the original rotation to improve gunnery and reduce loss of elevator control due to compressibility issues in high speed dives. Kram is absolutely correct that it doesn't really matter on our model aircraft anyway, but scale is scale! Small point but part of what makes the P-38 so friggin' cool!!
"The critical engine of a multi-engine, fixed-wing aircraft is the one whose failure would result in the most adverse effects on the aircraft's handling and performance. On propeller aircraft, there is a difference in the remaining yawing moments after failure of the left or the right (outboard) engine when all propellers rotate in the same direction due to the P-factor, Torque Variation to centerline, Asymetric Slipstream, and effect on Vmc.
Most aircraft which have counter-rotating propellers do not have a critical engine defined by the above mechanism, because the two propellers are made to rotate inward from the top of the arc; both engines are equally critical. However, some aircraft, such as the Lockheed P-38 Lightning had propeller rotation purposely reversed to reduce downwash on the central horizontal stabilizer, to make for better gunnery. These engines were both also equally critical, but more critical than inward rotating propellers.[SUP][6]"[/SUP]
