Official Black Horse 2280mm F4U Corsair thread

Comparing the original design assembly manual to the newest design assembly manual reveals extensive upgrades from 2010 of course. Robart style hing pins, retracts and gear, tailwheel is a retract now, motor boxes and no longer a Cowling ring - replaced with 4 cowling elbow mounts. Carbon fiber skin covers "ALL" wood surfaces of the fuselage, internal lattice work and motor firewall and motor boxes. The assembly manual does not have any instructions for the motor boxes. However I can assume the larger box with the offset should be the electric motor box. The motor box is pre-drilled for the Electric X Mount holes and does appear to be within a MM of perfection to the Admiral GP-60 180Kv Motor holes and the Admiral motor is within 1mm of the old Rimfire 65cc Electric motor mounts....so the cowling alinment should fit perfect with the Admiral motor. I am wondering how the blind nuts are going to seat into the carbon fiber skin without splintering everthing around them.

I am impressed with the all the components so far....although I have not tried to dry fit anything yet. The tail wheel retract is exceptional and should work great....too bad all the inner working and frame will be hidden in the tail.....which is also pretty heavy!

There does not seem to be LED's or wiring for the wing tips or fuselage beacon....so this will have to be a custom retrofit.

The landing gear retracts look nice and should hold up just fine...but I have not powered them up for a test run yet.

So far the kit looks good without any issues from the unboxing!

Digging the CF! Nice quality upgrade.

Any chance of more photos of current design.

As of 10:00pm 03-06-22 Motion remaining stock shows 10...I think this airframe is selling fast

Airframe delivered last night....was not expecting carbon fiber skin fused to the ribbing and internal support structure....the inside balsa skin is also covered in a fiberglass printed resin layer. This explains the light wing loading....super light airframe.....the covering probably makes up 80% of the weight

The Robart 148's pretty much drop right in. You have to grind a couple of notches in the mounting rails to clear some round head screws and to clear the rotating mechanism. The struts are already the correct length. You do have to grind a small notch in the wing spar but there is plenty of room to add reinforcement back. If you look closely at the photo you can see where I've added carbon strips onto the spar above the area that I notched out. The existing mounting bolts and holes also work. The gear door to strut mount will need to be modified. I used a small block of foam glued to the door with a small zip tie looped around the strut.

Looks like Blackhorse models are showing some sticker shock.....gone up quite abit on this model....gulp

Flying the Hanger 9 88inch Ki-43 Oscar is fantastic performing R/C on electric power train - exceptionally solid airframe.......in contrast reading threads regarding this light wing loaded Corsair landing gear has stopped me from moving forward on it. Looking at the BH P-40C and I can't get past the nose cowling...circlilng back to this Corsair. Does anyone have confirmation the Robart pnuematic retracts will fit this Corsair?


TwistedGrin

I will let you know shortly about the Robarts. I have a set of Robart 148 pneumatic retracts under the Christmas tree. The struts looks to be about a half inch shorter but it shouldn't be that hard to lengthen them a little bit. I can't stand the looks of a Corsair with little tiny wheels or short struts.

[Rccen44]

Has anyone installed Robart retracts to the new version of the corsair? If so, which one of the retracts did you use?

[TwistedGrin]

Passing on other ARF's availalbe from other manufactures.....still waiting on this birds shipping to the vendor. I have reports from other Pilots that remarked the Blackhorse model Corsair was an exceptional performing flyer. I am not sure how much longer I can hold this out Captain.......!!

This model doesn't seem very popular. After working on it a bit I think it lacks scale fidelity for the price. If you spend on after market gear and everything to make her more attractive than she arrives in the box, the investment is too high. However, paint is cheap and I decided to dress up the cockpit a little. I still need to make the gun sight, rudder pedals, and finish the throttle quadrant. The instrument panel looks much nicer blacked out. My canopy is a foggy piece of crap and I haven't decided what to do about that just yet.

I think the Phoenix may look better while the Blackhorse may fly better (Lighter)

I'm 3d printing some main gear doors to test fit right now along with more scale looking oil cooler grills.

Interested to know how these turned out. If they turned out well, would you be interested in selling a set?

[WrightBrosRC]

Ordered my Black Horse Corsair today. I will put the larger wheels on and fab some main gear doors. I have a very nice UMS 75cc 5 cylinder radial that should fit just fine.

I was gonna make gear doors too, but I'm just too damn lazy. The 5 cylinder will be awesome!

Thank you WrightBrosRC, that's what I needed to know.

What is the largest main wheels that anyone has put on their Black Horse Corsair? I want one of these planes but I just can't get past those tiny wheels.

I'm using 5 inch Dubro treaded inflatables. Larger diameter will hit the retract motor housing. Plenty of room in the wheel well.
