Lockeed Constellation
 
Anyone know of a kit or Arf of a Lockheed Constellation available in the US

crxmanpat 05-13-2014 07:40 PM

I've not seen one, and I've looked hard. The closest we had was a laser cut balsa/ply kit that was at one time being offered by Manzano Laser, it was a Philip Noel design. But they no longer carry it.

If you find one, please let us know.

It's big!

Unfortunately, none of our suggestions are ARFs. :(

thepiper92 05-14-2014 03:35 AM

Wow that is one beautiful plane. I gather it wouldn't be an easy find for arf, or even kit, as it isn't a plane as well known as such other planes like a B17, B29, and so on, but still, it would be a nice model to have. Maybe you could ask Charlie about it, may have it floating around somewhere.

I think Phoenix models makes one and it may be sold through a distributor in Oklahoma
It's huge. Gotta love the Connie. I'll check. Btw, welcome to WF !

EDIT:

http://phoenixmodel.com/phoenixmodel...?ProductId=327

zigirc.com is their US distributor. I have a 40 size Tucano EMB-312 I bought from Tower for $118.00 shipped and it was the best ARF I ever ought bar none. Phoenix is very "old school" Great sheeting. Solid construction abound.



The Super Connie is way beyond my budget, patience and skill. But, there is one available.

Hawk,

Did you see the Connie on the Zigi site? I can't find it. What price did you see?

dahawk 05-15-2014 02:27 AM

Pat,
Don't think they are offering the model even thought they are a Distributor. Probably due to sheer size and weight. She's a hoss !

fhhuber 05-15-2014 02:33 AM

Their B-25 ARF (slightly smaller using a pair of 50cc engines) was about $2500 when it was available. I expect the Connie would be a bit more.

buzzltyr 05-15-2014 11:48 AM

Easytiger Models supposedly has one. They don't have the best reputation for customer service, but they list it on their website. $4995. 150" wingspan. He had the fuselage at NEAT last September.

I am aware of those models you have listed, but this being an electric powered forum, I was hoping for suggestions for a project using electrons not gas

CHELLIE 05-15-2014 08:15 PM

The Constellation is not a widely modelled RC aircraft, but it should be, because it such a beautiful aircraft, unless a person wants to spend the $2500 to $5000 for a arf, a person will have to scratch build one, and that would be a undertaking, just about any gas rc aircraft, can be fitted with E Power, Take care, Chellie

fhhuber 05-15-2014 10:49 PM

E-Flite Power 160's or equiv would easily replace 30CC gas.

We could put e-power in just about anything including the Hempel Fokker Dr1.
All it takes is money...

Yeah
When you get into giant scale models, IMHO, it's a good idea to use name brand quality equipment in your power system. Per the attached portion of that chart referred to below, that DLE 30 gasser is about 85% of the horsepower or watts output than the E-Flite Power 160, or the Hacker A60-16M motors. Something to keep in mind. Big electric motors swing big propellers. Make certain that your model has ground clearance and prop to fuse clearance with big diameter props. My Hacker A60 can run props on the order of 19 or 20 inches in diameter. I ran into that with a giant Cessna model. Had to extend the nose and main landing gear two inches higher.

Electric is going to be much more expensive than gasser, but for a model of this size, my club members have indicated loosing an engine on a model like this will very often result in total loss of the model. If you go up to an electric conversion of a 50 cc gasser, the electric price skyrockets.

Here is my thread on this subject, where I went through a real stack of RC magazines, looking up various glow/gas engines, along with electric power, and put their power capability into three different charts.

Yep... long props can be an issue. When I stuck a 22 inch prop (12S and a supposedly 5000 watt rated motor... that melted the glue holding the magnets out at 120F) on a plane designed for a 1.20 glow it was a bit entertaining figuring out what to do for ground clearance.

Can't just stretch the gear legs on a scale model. But that's why they make 3 and 4 blade props

Holy crap. :eek: 5KW on a model designed for a 1.2 Glow engine? Hand launching must be easy, just point it straight up and let go :D :D :D

fhhuber 05-16-2014 01:10 AM

It was impressive... motor was RATED 5000 watts... I was pulling about 3700 peak. 13 lb 2 meter long 75 inch span Pattern plane (I could make the 11 lb limit with a 10 cell pack set)

It got in a couple of flights before the magnets shifted. I could take off at 20% throttle, point the nose straight up and hammer throttle and accelerate like a rocket ship. In danger of going out of sight high in 5 seconds.

The replacement motor spit the bell prop and spinner when I hammered the throttle from a standing start.

One of my club members went to a local pattern contest last summer. Out of 14 pilots, only one was glow powered. All of the rest were electric, 2KW or more.

One thing that worked for me to secure magnets in a build it your self brushless motor was the old baking soda/real thin CA trick. That stuff was put between the magnets. Heat from a hot air gun has little effect on that stuff. You need a metal file to remove it.

Trying to re-glue magnets in a big motor, what with the crud from the previous adhesive (????) along without having a magnet alignment tool would likely be a lesson in frustration.

fhhuber 05-16-2014 01:37 AM

That's why I haven't ever put the magnets back in. Can't get the all of the hot melt glue out.

Gluing in magnets for a little 150 watt motor was really frustrating without a non-magnetic fixture type device to hold the magnets in place. I had to machine one out aluminum. Doing that for a 5KW motor would be impossible without some sort of fixture. Even with a clean bell housing. Those north-south-north-south poles attract each other, and they all wind up in the same place.

thepiper92 05-16-2014 02:54 AM

I reglued a magnet once with ca and baking soda. It worked somewhat, not perfect. Motor works still and smooth at high throttle ranges, notched sounding otherwise. It's a bad quality motor anyway, so it works well enough.
