Official Black Horse 2280mm F4U Corsair thread

Check with TruTurn ! I had to purchase after market shafts for all my larger epower models, depending on the brand of motor selected.
There is a lot of talk on electric motors on all of these new planes, however I don't think one video exist ( even from the staff ) at motion.
Plenty of video on gas power, would love to see the actual model in use with 12s, and get some real world numbers.

Love the progress Bandit. Someone needs to come up with a replacement prop shaft for that motor that is longer to allow the dummy radial to sit further back in a more scale position. Or do any of the larger electric motor manufacturers provide motors with extended shafts? I'm sure it would put more load on the shaft bearings but even just another 1/2 or 3/4 inch would make a huge difference. That too forward dummy motor has always been a problem with radial engines looking right. Another option would be to slide the dummy engine back a bit to get the right distance from the front of the cowl and disguise the front of the electric motor as the gear case behind the prop. Just thinking out loud.

Man this is a awesome looking model!!

[bandit]

So i got my Ramoser prop in and it looks fantastic. This is a 18.6 diameter that i have pitched to give me 90A full throttle.

[Aros]

I had Ramoser varios on a balsa Stuka a few years back and my oh my, worth every penny.

[OV10]

bandit You're not weak...……. that's the scale freak in ya coming out
PS.....you can see a 3 blade when it spins or you aren't staring hard enough
I've got a ESM Tigercat which meant I had to swallow twice as hard for the Ramosers but DAMN does it look good

[bandit]

You can only tell when the motor stops spinning. Having said that, i checked out the Ramoser props and they look amazing. I ordered one to play around with. I'm so weak.

[Aros]

Yeah I figured the 2 blade would be able to give you best performance with lower amps...I went with a 4 blade for my ESM 85" Corsair though because, well, I couldn't help myself, lol. Looks over performance, that's my stupid motto of the day!

[bandit]

I have considered a 3 blade, but to get the same performance as this 2 blade setup, i would need a larger motor and the current draw would go way up. As it is here, i pull 80 amps. The plane weighs 23lbs and i have 22lbs of thrust giving me almost unlimited vertical, with a static prop speed of 70mph. Flight time with throttle management is about 8 min.

[OV10]

Nice work there bandit ! Great job with that cowl space...Would you ever consider a scale 3 or 4-blade prop for her?

Was gonna ask the same considering the freakin awesome printed radial only to stick a 2 blade in front of it. Definitely worth the invest into a Ramoser for this

[Aros]

So i finished the build. I was worried about the CG going electric and with good reason. I had to put every available thing in front of the firewall to get the CG to come out right. That includes both the retract battery and the receiver battery & ESC. i went with the biggest receiver battery i could fit just because i needed the weight. I also 3D printed the radial dummy engine and that added some weight as well. Have not flown it yet due to the current virus situation. Some pictures below.

I decided to mount the dummy radial to the motor mount ring instead of the cowl. This way it stays with the plane when the cowl is removed.

I love how you did the radial. Looks really nice and I can't wait to see her in the air if you will be able to get some video. Great work!

It might be difficult to beat Hangar 9 when they don't have the plane available!

F4U-1D Corsair 2280mm (89.7") Wingspan from Black Horse - Balsa Wood ARF - BHM1000-001

It's finally here, the largest fully sheeted balsa Corsair from Black Horse with a new design, new features, and new covering! The Corsair was designed and operated as a carrier-based aircraft, and entered service in large numbers with the U.S. Navy in late 1944 and early 1945. It quickly became one of the most capable carrier-based fighter-bombers of World War II. Some Japanese pilots regarded it as the most formidable American fighter of World War II and its naval aviators achieved an 11:1 kill ratio.

The model is scaled to approximately 1:5 and attention was paid to a true to original appearance and best flight characteristics. The model can be operated using an electric power system or with an internal combustion engine about 60cc displacement.

Factory Weathered Printing The printing on this model has a realistic weathering complete with rivet and panel line detail that elevates the model to a whole new level of scale appeal. Black Horse really takes it to the next level with their weathered covering. It serves as an acceptable flight-ready finish out of the box, and also provides a good base to help fast-track further DIY paint customizations to suit your preferences.

Full Retractable Landing Gear Aluminum suspension struts on the landing gear absorb rough landings on grass surfaces. The tail landing gear is fully retractable also, replicating the scale articulation. The tail wheel's mechanism hinges and extends just like the real Corsair!

Gas or Electric Power You can choose between gas or electric to power your model depending on your preference. We prefer gas for a model this large, but there's cavernous space for an electric power system on 12s.

High Scale Fidelity Operate one of the largest and most realistic Corsairs on the market. Black Horse updated a variety of aspects of their previous smaller Corsair's design, then upscaled it to this giant!

Large Wingspan The Corsair has an impressive 89.7" wingspan for impressive presence both in the air and on the ground.

Removable Main Wing Easy assembly and intuitive design allows for the main wing to be removed for transport. Durable nylon pin-hinges are used for all flying surfaces, instead of CA hinges.

Scale Flaps The three-stage flaps are iconic and fully functional, with rounded leading edges.

FEATURES:

• All new design
• High level of prefabrication right out of the box
• Lightweight, strong, laser cut balsa and plywood construction
• Rotary 90 degree electric retract gear and CNC suspension metal struts
• Panel lines and details printed directly onto the pre-applied, high quality covering
• Model officially licensed by Northrop Grumman
• Airfoiled tail surfaces
• Pre-drilled hinge mounting holes
• Heavy-duty pin hinges on all control surfaces
• Large easy access fuel tank/battery/servo access hatches with sprung loaded latches
• Painted and detailed cockpit, pilot and interior included
• Fiberglass control horns with ball link connector
• comprehensive control and fitting accessories included
• Two-piece, plug-in wings simplify transportation and assembly
• Fiberglass cowl and glass reinforced landing gear covers/pants
• Mounts for both electric and gas power options included

I shall enjoy watching you bury hanger nine ..... your customer service will pay off

[bandit]

I will, It will take a few days to get the pictures

[Joehockey]

When you have a moment , could you please post pics of your build ?

[Joehockey]

The weight is very encouraging!
The wing loading would be very light at 19lbs

[bandit]

So my curiosity got the best of me and i weighed all of the pieces and came up exactly 19.5 Lbs not counting flight batteries. This includes a 2cell 3000 lipo for the retracts and a 3cell 3300 with 20A BEC for the receiver and servos. With 2 6250 roaring top 6cells, the flying weight is 23 lbs. Two pounds lighter than the topflite corsair with the same power system.

[bandit]

Also, the current draw on that setup is 79A which with throttle management give me 7 min flying time.
