Suitable planes for Cox 049 power

Thanks Kari, will go and have s look see...

Any others gents ?

I used to fly a 1/2 A sport stealth on a Black Widow. It was a very fun plane. I think the kit was by House of Balsa.

It is an HoB kit, got one sometime back when Hobby Shack (became Hobby People, now forever gone) was still open and had the kit in stock, for my bucket list of do's.

Black Widow is more than adequate. Plans and photos show a Cox .049 Dragonfly R/C exhaust throttle engine, mainly an aileron-elevator fun plane.

I think if the OP would narrow down to exactly what type of half-A aircraft he is looking for, could make it easier for us to suggest some. (Pylon? Pattern Stunt? Speed? Single channel? Scale? Ease of building? Powered glider? Warbird? What war era? etc.)

For a quick build project you can convert a foam arf.

I came close to buying that little Rare Bear foamy ARF.. but the shipping was more than the model..

what is the wingspan and weight of your rare bear and where did you purchase it? Thanks

I like to save time so converting a foam model to be powered by a Cox engine is a good way to build quickly without worrying about electronic components. I prefer balsa wood but I am sure that foam is a good choice And certainly less. Expensive and certainly less time consuming than building the complete set with balsa wood, I had good results with models powered by a brushless 250 motor. It is with this model that I had one of the most beautiful results I added elerons and a Cox sure start rc engine

Check out Willie Nillies.
They have a bunch of 1/2A R/C Kits.

Looks like a simple and robust little plane, strong enough to carry the old NiCd battery pack, should fly pretty good with a modern setup

The example model has a Tee Dee, but such a small and light plane should fly well with a strong reedie too.

      Hello KariFS
                            I built the live wire trainer about 30 years ago with a cox TD.049/Tarno carb combo. I flew it many times with my kids. The only advice I have is to use two dowels in front to hold the wing inline with the thrustline because if you go on a fast dive the wing will pop off with the single dowel angled like in the plans. Here are pics.

Nice photo of your sons, Juan. I bet they had a total blast flying with you and watching the Livewire fly. Regarding the two dowel approach replacing the designed single, I did this with Sterling Minnie Mambo too. There, they doubled up the dowels through the top front of the cockpit. It just looked dorky to me, so I changed it to standard.

You make a good point as there are also other R/C half-A and A planes that used this single front dowel. They'd fail similarly, too. I wonder how many watched the wing flutter down as the fuselage lawn darted into the terra firma.

Hello Gallopinghosler
                               I had let a friend fly the plane and he took it up high so I went into a shallow dive and as the plane gained speed the wing peeled off it was still high so I hit full up elevator and full right rudder and the elevator also peeled off as it was held on with rubber bands also. Then I watched it do a one point landing and broke the prop. I have a bigger one that I built for an K&B.09 but have not finished. My boys now are 40 and 44 years old. They enjoyed going to the flying field and I taught them to fly Radio control.here is a pic.

Juan, failed to see the 30 years ago part. I did the same with my kids, then my daughter was 7 and my son 12, took them to the north side of Gallup, NM, flew my half-A planes at the National Guard Armory in a vacant field next to them, late 1990's. Did model rocket firings in the canyon between mountain ridges just north of there. They enjoyed watching the planes and gave them hands on in firing model rockets. This was before moving to Clovis.

My son's just a year younger than your youngest one, brought the grandkids some Guillow rubber band powered all balsa flyers and gliders. Oldest son starts 7th grade this year.

I've got the junior kit to your Livewire, the smallest, the 34 inch span DeMECo (DeBolt Model Engineering Company) Livewire Kitten. May be once settled, build and join @Kim and have a ball flying single channel half-A with throttle. May be go wild with an exhaust throttled Medallion .049 engine.

That's an nice looking little RC plane , fitted with 3 channels would bee a blast even in small fields ? Most of my RC s are big with large fuses and WS 56" and more I need a lot of room fling and a smallish plane I think would help out .

You can make it 3 channels, but it is only one - rudder. In 1953, only a single channel tube receiver could fit, with two or 3 photo-flash batteries (22.5 Volts each, same snap battery connector and form factor as today's 9 Volt transistor battery but about 0.25 inches longer) as the tube amp's B+ supply and 2 AA dry cells as the tube filament A supply and 2 AA as the escapement electro-magnet supply) was the flight battery pack.

Mind you, these were standard lower capacity zinc-carbon batteries, they didn't have alkalines or higher powered batteries then. I'd think one got maybe a dozen flights max out of the pack. Probably had some fly-aways as well, due to weak batteries.

The super-regenerative circuits were not very selective. Nearby frequency transmissions could interfere with the receiver. But, this was flying. It wasn't until companies like Ace R/C made miniature single channel Superheterodyne circuits using transistors, that then one had better reliability and sensitivity for good R/C control. I bought one of those systems in 1972 for $70.00 from a hobby shop in Virginia Beach, VA. (Due to inflation, cost today would be $526.74, the price of an economy say 60 inch (1675 mm) LCD TV.)

If you haven't flown pure single channel, it is a total blast. It is amazing how one can maintain control with only 1 channel. I did that without throttle then. Nowadays, I'd include throttle, which expands single channel flying abilities.

Back to Hal DeBolt's Kitten, it's trim is set up for single channel rudder only flying. This includes the decalage (angle of attack) of the wing and stabilizer. An oddity, it has a lifting tail with the modified Clark-Y flat bottom elevator.

For true 3 channel flying, one would be better off selecting a half-A plane designed and trimmed for 3 channels. My Q-Tee was such a plane.

Thanks George , didn't think about all the changes needed to make it fly right , I had a single channel long time ago and when it did get in the air ran into the school over the front door overhang LOL friend went up and got it , wasn't damaged then, took home while charging the battery's they blew up and out the side ! Big hole The end ))

Thanks for the tip! I don’t really understand the one dowel thing, two is so much better. I have a Blue Phoenix (a 2m glider, kit by Hobbyträ in Sweden, quite similar to Gentle Lady by SIG), its wing is split in the middle and it has one dowel in the front, another in the back. The rubber band sometimes tries to work its way in between the wing halves. I used tape to keep that from happening. Kind of a hassle.

If I were to build the Little Live Wire, I would probably mount the stabilizer permanently, and go 3 channels too.

Hello
              I Built a plane similar to this model using Ace foam wings but they are not available anymore. Manzano lazer works sells a balsawood copy of the wings that can be built either straight or tapered that can be used to build The 1/2A SST designed by Vince Micchia that was sold by Hobby Shack . the plans are in Outerzone. Here is a photo from outerzone that shows the model. The plane is flown using ailerons and elevators and throttle can be added.
The plane I built it was a hoot to fly  without landing gear.
