Official Black Horse 2280mm F4U Corsair thread

TwistedGrin how do you feel about the weathered covering? I've heard both ends. Cheesy to very cool.

Storage challenges.....PVC balance rack. Uses the wing spar tube as a balance catch, spinner resting on high density foam block. 1inch PVC with easy acces.....a wooden dowel goes through the wing tube and held captive in the PVC frame with a small wire nail. The frame is only meant to hold the model balanced while resting on the propnut. This is NOT for transport.

Ya - I followed your lead and measurement for a base line to confirm .....I too will fly about 6-7min per flight. Let the batteries, ESC and motor cool down between flights

Had to triple check my numbers to cut the motor mount extensions right....after moving the cowling forward as desired....then find the blasted bolts with enought threads to work correctly. Lots of process there for a minimal task - LOL

Looks good and proper.....now

Thanks again for posting up !!

Your cowl appears to be spaced about like mine. My gas radial does not get hot at all. Granted, I don't fly 15 minute flights, I tend to fly 5 or 6 minutes maximum.

[TwistedGrin]

OK ...measure 10times at midnight and 10times again at 10:00am then drill....then go find new bolts with long enough threads and new blind nuts to match the bolts.

Thank goodness for the local farm implement hardware feed store...both Lowes and HomeDepot failed me....had to change out from metric to SAE and from fine thread to corse thread.....but I got it done without chewing up the internal plastic cowl mounts.

I don't have enough motor clearance to have the prop very far out from the cowling face as this 60cc electric motor will grind on the faux motor backside.... the new cowling spacing is matched again with the motor prop offset.

I do like the space that is now open to pull some airflow.....good as can be for the Texas triple digit dawg days of summer now

I chose to fill in the original cowl mounting holes with flathead screws backed with popcicle stick wood on the inside to help hold them in.

All that I need now is for the prop nut to arrive and then triple check the CG.....wondering if I will see any difference with the motor forward about an inch

10:4 Thanks for these photos and measurments RCCN44......

I removed my prop...pulled the cowling forward .23mm/.9inch and I like the gap spacing much better...looks like some air can now pass through. Your prop clearance is very close to what mine will be if I move everything forward. I am making plans to make this adjustment. Hate to drill new holes in the cowling...but can probably hide the original holes with filler and paint.

I feel a little "short" for not realizing this during my initial set up....would rather fly cool than not...so the adjustment is justified.

Thanks again sir!

My cowl is an inch from the hatch and my prop has about 3/4 of an inch clearance between it and the cowl.
Corsairs always seem to have a lot of prop to cowl clearance.

[TwistedGrin]

I just discovered that I have my motor or Prop set up a little shorter to most photos I see. The GP60-180KV motor is pretty long....too long for the motor and the larger motor box supplied with the kit.....therefore I had to use the shorter motor box mount and cut my own motor mount extensions.....I could have made my motor mount extensions a little longer perhaps. My cowling is dead even with the front of the forward hatch line....so I figure I am set back a little shorter most perhaps!

Looks like I can go about 1.96inches further out perphaps by cuttting some longer motor mount extensions

Not sure if this will affect flight performance or not

Updtate on my F4U-Corsair prop hub....True Turn (Wendy) knew exactly what I had...even double checked that the XOAR PJN prop for electric is smaller diameter than the standard "Gas" XOAR prop. She stated the 4-bolt E-Flite Power 360 prop hub is same as DLE/DA 4bolt prop spacing and pattern. She is handing my order to the shop to crank one out today maybe....that's called expertise, knowledge and true customer suport!!

I have used Tru-Turn several times for custom hubs and they are fantastic. Worth the price. Wendy is excellent.

TwistedGrin Here is a link to the spinner I used on the 60cc electric set-up on the Gilmore. It should be the same colt pattern as the Admiral GP60. It should look right for the Corsair. It's as good as the Tru-turn IMHO.

Wow 10:4 and thanks Twowingtj....this aluminum set up should be much lighter than the TrueTurn......I can use the TrueTurn as a back up plan or sell it to the other fellas in our club who have the Corsair's

Have to say...if was a gasser that set up would be my choice 100%. Nice sound, great flight and nifty 3point landing.

I am having difficulty finding the correct True-Turn prop hub for the Electric motor set up I have for this Corsair. The Admiral GP-60 is identical to the E-flight Power 360 with the 4bolt prop face....I "think" it the same pattern as a DLE motor? So I am looking for the Corsair type prop hub that would fit over the 4bolts and large prop washer I guess.

Thanks, I get lucky ever now and again on landings.

[Aros]

Now THAT is a beautiful sound! And nice landing too!

I don't know if this link will work or not but it is the only video I have of the plane so far. The video was taken with a cell phone looking down at the ground most of the time so I cut all that out. That is why the video jumps around so much. My Corsair is a very nice flying plane but you can tell I was having problems with the electric retracts. It takes a while to get all up at the same time. I have Robart 148s now and they work very well.

RCCN44 - You are in a class of your own with that motor and prop....all business. That must be a real treat for everyone to in flight. EXCELLENT

I am at 1100 feet above sealevel. The flaps slow it down nicely, just keep a little power on and fly it all the way to to ground. It lands easier than most warbird type planes. No tendency to nose over at all. Yours is lighter than mine, so it may want to float a little on you.
The prop is a 22 x 12 Biela scale-ish propeller. They do look good on the front of the Corsair.

It is 26.5 lbs. I have no ballest weight. I moved the two 5500 mah lipo batteries around to get the cg I wanted.

Roger that.....I seldom wind up within the manufacture overall weight ....good to know you are flying this bird. If same bird in your profile that 3Blade prop provides a good look for the F4U.

I may try a 3 Blade after I get some flight time on it via 2Blade.first.

At 25-26lbs I can assume it's NOT a floater

The fitment of the wings is pretty good....tail fins look straight....no twist in the frame.....if anything needs adjustment it will only be the motor offset and CG tweaks on my bird.
