Default No more retracts

I ran into a continuing string of problems with my factory retracts and my rougher-than-normal grass field. After the second set failed, I retrofit my Mustang for fixed gear. It was a bit of an engineering challenge to mount everything and get the stance right, but I am happy I made the change. No real difference in flying characteristics, but I sure miss the "cool" sight of the retracts doing their thing. I don't miss the sight of my gear folding up on landing!

Chris,

That's too bad as this model is certainly a looker without the gear hanging out while in flight. I would have purchased some stronger retracts "metal" perhaps that pretty much drops in and I would seek a set within Tower Hobby or HobbyPartz and other USA distributors.

I bought a set of RC Lander metal housed retracts for $25 from Electric Jet Factory. Take a look at these.

I have installed and flown the E-Flite .10 electric retracts and can report that they work great. Always work and sturdy. They also have a nice slow extend/retract cycle (not too slow) and they operate independently so that also adds to an increased scale like appearance.

Carlos,
You are a trouble maker.
I've recently discovered your new mustang and have GOT to have one. I'll remove all of my gear from my wrecked WM model and install it in the Airfield model. Everything should work out great. The "kit" version is very reasonable at $99 from Nitro and from what I've been reading on the RCG thread, it's a great flyer.

BTW: I recently finished building the Windrider Dauntless SBD and it's a real looker. I detailed the cockpit with pilot and gunner figures, added some paint for detailing, and installed "ammo" in the twin .30 cal.s . I haven't flown it yet but, that may happen today if the winds are right.

Default Thursday (12-26-2013) Morning RC Flying

I had not flown my Beloved TWM Mustang for over one solid year and you can see for yourselves that on Thursday, (12-26-2013), she came with me to the RC Club and flew majestically and most especially graceful. My model is super LIGHT using the E-Flite 480 (1020Kv) and 3-Cell, 2200mAH, Lithium Polymers with the Hitec Receiver (FM) and my JR XP-7202 FM transmitter.

Here are a few pictures of my model Post Flight from this past Thursday!

Yes, it has been almost 13 years but, I still have my beloved World Models P-51D Mustang!

Okay guys.....

After some additional tinkering around with the mechanical retracts, I gave up and decided on E-Flite 15-25 size E-Flite Retracts. The E-Flite Retracts were bought from eBay a few years ago and finally took the initiative to change them out on this World Models P-51D 40 Mustang.

A few things to keep in mind and items you will need for this modification:

1. Dust mask and Safety Glasses, no kidding please wear a pair.
2. You will need heavy duty wire cutters.to cut the ends of stock slightly bent wire struts.
3. Dremel tool on the lowest speed setting, in case your Dremel accidently touches the covering.
4. Using Dremel - sand away both sides of stock attaching mechanical retract plywood rails and square off opening of retract cavity.
5. Fit check the E-Flite 15-25 retracts and repeat step 4 as required.
6. Feed in a 6-inch or 12-inch servo extension and connect to E-Flite 15-25 retract.
7. Once the E-Flite 15-25 retract stays flush on the wing opening cavity, check for function and see if retract wire enters the cavity.
8. If not, repeat Step 4 as required.
9. Use a drill with the appropriate size (depending size wood screw) and drill holes for securing E-Flite 15-25 retracts.
10. Repeat Step 7 before screwing in anything yet.
11. Using Dremel tool, dermal a FLAT Spot on the stock strut wire so, it will not rotate and provide a secure fit when tightening set-screw.
12. Once you are sure all is functioning okay, use appropriate screws and using a small screw driver, screw in the wood screws slowly.
13. Clean area as required with a clean dust rage or clean paper towel.

In Step 6, I used a typical 12-inch servo cord extension and worked really well when using a dental floss tied at the male end with a tiny nut and using gravity the nut goes in the mid-section of wing and goes down the ribs until it reaches the Servo Cavity.

Again, Please use eye protection and dust mask as this modification has induced hazards from flying (ballistic metal) when cutting stock strut wire end and use a dust mask when sanding plywood with high speed Dremel tool. Please stay safe!

Video Showing Post Modifications Flight and model got new wheels / Tires and had to slightly bend stock strut wire where wheel is inserted to avoid tire from rubbing on the vertical strut wire.

Here's the Video:

Very nice flying Stang. The retracts are a great idea Carlos.

Thank you Don!

It is perhaps one of the best RC Airplane Models that I have in my fleet. The closest second is the Hangar9 P-51D Progressive Training Series (PTS) converted over to Electric as both of these models share a common positive trait and that is Low Wing Loading which provides ZERO bad habits for the RC flyer.

You see the model in a different light and at times in amazement with the appreciation of the design in mind for light wing loading to really make it shine up in the air.

Oh, I ordered the Stock Strut Covers and a brand new Cowling to give it that extra appreciation factor! LOL!

Guys,

I can't believe that I purchased this model so long ago! (November 12th, 2008)
https://www.wattflyer.com/forums/sho...52&postcount=1

What I posted back then, still rings true today and that was:

I actually did not purchase this model because of it's scale detail but, rather it's Light construction and strong assembly up front where it counts unlike some E-Flite models that have honeycomb Frontal Fire walls. This Mustang has a solid Plywood mount with screw retainer inserts already drilled in for the World Models recommended Plastic Mount for their Outrunner Brushless motor.

Guys,

A few have PMed me about the actual weight of my model and have just completed a Weigh-In session and here is the results!

Total Flight Ready weight: 2.922 lbs.

Just amazing for a 49 inch wing span Mustang!

No wonder it slows down super slow and of course it didn't need any flaps in the design from factory.

Therefore, the E-Flite 15-25 size servo-less retracts didn't add any weight beyond the already weight of the stock mechanicals and HS-81MG servo in comparison.

Okay guys,

Decal Sheet and Air Scoop was ordered as well to keep this model in top Eye Candy looks!

1. Previous order on 10-7-2021 the Cowling was ordered because on the Maiden flight back in November 2008 the model had a hard landing.

2. Air Scoop for today's order is because the present Air Scoop sustained Textile Runway black marks because Stock Mechanical Retracts didn't hold on a recent flight (Before the Servo-Less Retract Modification) and nothing I use can take off these marks so, a new one was ordered.

3. Decal sheet was ordered because want to dress up the new Cowling.

4. Landing Gear Covers - self explanatory!

Guys,

I almost ordered from Callie Graphics as I had thought that Airborne-Models didn't have the decal sheet and behold they did.

I found this following Video from Captain Ryan very useful and entertaining and wanted to share with all of you in case you need to figure out the scale of your model.

North American P-51D Mustang had a 37 Foot wing span which equates to 444 inches.

My model in this thread has 49 inches of wing span thereby,

444" / 49" = 9.06 "or" 1:9 ratio "or" 1/9th scale

Sunday morning at the RC Club field allowed two (2) wonderful flights back to back of my World Models P-51D 40 EP Mustang.

There was a slight breeze but, it was steady and no gusty winds.

Was able to record two (2) Flight Videos of the model and the first landing was a complete stall from perhaps 2 feet off the deck and very pleased of these E-Flite 15-25 size retracts being able to take the punishment and of course the low bounce rubber scale tires. If these were the stock mechanical retracts I would be replacing the mechanical servo as it would have stripped by now.

In any case, here's the videos:

Thank you, Don.

I got to keep in mind that even though this model is pretty light, I have to keep some airspeed on landing. The wing Airfoil is not that forgiving if you slow it too much, especially applying UP elevator on final.
