Official FlightLine F4U-1A Corsair 1600mm (63") Wingspan

[xviper]

I am curious about the top end of this Corsair. Is it comparable to the 1600mm Spitfire?

What do you think if I used a FMS 17 inch 4 blade or the Spitfire's 16 inch 4 blade on the Corsair? What performance differences would I expect to see?

My first corsair (which I still have) is the 2nd edition Parkzone Corsair. Overtime, I put in a e-flite P25 motor and a 4 blade prop. It keeps up with most gassers and still retained its flight characteristics. I've been a corsair fan ever since. MRC, it looks as though you put everything I've wanted to see put into a corsair foamy since I started modifying my Parkzone! Wonderful!

I have your 1600 Spitfire. I'm very impressed with this plane. Looks great, great comments from the club, Impressive vertical power and so on. I do, however find myself trying to add more power. I add more throttle for more "go" and notice that my stick is at it's maximum. This is why I'm asking about top end on this model. I'm assuming that I already know the answer. I think that I wish that the plane's top end was more comparable to other 60 size warbirds.

When I purchase this corsair, I'm thinking about a later version Blue and white "Orlathe" version, which uses a 4 blade propeller, so that's why my first question.

Lastly, do you have any plans for a more realistic dummy engine? If not, I may have to spend a bit more time modifying.... :)

Thanks for in advance to your reply

As for whether this Corsair is comparable to the Spitfire, just look at the specs. Both have the same flying weight but the Spit has a 50kv faster motor, so one would estimate that the Spit would be marginally faster BUT, even if you had both of these planes, a difference of 50kv may not "look" any different in the air. The difference may show up dependent upon the aerodynamic differences between the two and even that may be hard to visualize. You'd have to put instruments on board to measure it. It's sort of like drag racers talking in the bar after the race. "I blew your doors off", when in reality, the difference was 1/2 a car length.

Xv, Acknowledged and Agreed, I might add that there is also an aerodynamic difference in these to airframes. It's an old question whether one wants a scale flight appearance of a particular airframe or a performance comparison or expectation to what one might be used to flying. I'll take the former as long as the aircraft is stable in a panic situation. Best, LB

The Corsair manual states that the top speed of the model in level flight is 125 kph or 75 mph. :Cool: FlightLine RC F4U-1A/D Corsair 1600mm Instruction Manual

After checking the Spitfire manual, it states the same performance specs as the Corsair. 125 kph or 75 mph in level flight with the 5000 6s battery...

I am surprised that FW/FL would put such statements in their manual. This could open up a big can of worms. Take the auto industry, for example. Car manufacturers would never open themselves up for scrutiny (or possible legal action) if they stated a product can do xxx mph top speed. Mind you, car junkies can be real nutbags (I'm one). They'll sue you if the car does only 149mph when the manual states it'll do 150.
In any case, when I get this plane, I'll fly it first and see how I feel about it. If it's too slow, there are ways to make it go faster. But I think 75mph will be quite adequate for this plane. I've got other ones if I want warp speed.

[fhhuber]

Studebaker used to advertise their cars could go as fast as the speedometer reads. In HS a friend's father rebuilt a Lark and the speedometer read to 150.

I think the Corsair's listed 75 mph is rated top speed (VNE). Which you rarely (almost never) see listed for a model. Its easy to modify for more power to make it faster... but with that notation, I wouldn't even try.

Or maybe not...............just wanted to remind ya that the Spit is turning a 16x10x4 versus the Corsair has the 18x12x3.
I know you understand the exponential power equations regarding props and motor Kv's loading.;)

Don't make me pull out my slide rule. LOL Nevermind, I can't find it or my trig tables. :Silly:

[downwindleg]

I have to throw this into the mix. At 75mph in 1/8 scale......that's 600mph!! :Scared:To fly at "scale" speed you really wouldn't want to go over 50mph which wood equal the real plane's top speed. Just sayin'.;)

What's the "real" top end of the full size plane? I always thought 600mph was within reach. I've heard of a P-51 almost breaking the sound barrier in a dive once.

Dodge has listed top speeds on their website,I cant remember if it is on my paperwork but the official Dodge website states my Challenger is "electronically limited to 185mph".:Cool:

440 mph, give or take a few.... :arrow:

Mercedes and BMW do that, too. Being “limited” to a stated speed doesn’t necessarily mean that’s it’s top speed. They are confident that it will go faster than that. They just don’t let it. So limiting it is pretty safe.
with respect to stating a car will go as fast as the speedo goes up to is also somewhat safe since we’ve all seen the kinds of speedo errors some cars have. In 2015, VW Golfs had a built in error of up to 10%.

[paladin]

if your scale speed will not provide enough energy to do a 7g turn (80-82 degree bank) level turn for 360 degrees, its not scale speed.

G is a factor of speed and turning radius... Scale turning radius and scale speed may or may not give the G force imposed on the full scale at its max G performance.

Scale speed is a false target though. For many models, they wouldn't even achieve minimum speed for sustained flight at scale speed.

We calculated the G forces on Pattern Aerobatics models and came up with in excess of 45 G for some maneuvers.
Dynamic Soaring models have pegged out installed G meters that read to 100 G... long before they achieved maximum speed.

Its likely this Corsair will exceed 25G with ease.
Note.. our turning radius is far tighter than scale.

I need to find a job, I want the Birdcage version so bad , anybody want to buy me one

New to Squawk. Lots of great info here. Pertaining to the new FlightLine F4-U 1600mm (Bubble Top) Corsair...… As you know Motion has it as a "pre-sale" and they expect availability late January BUT those knot heads charge your card immediately which is against most CC companies T&Cs. Once a merchant charges your card they are required to ship the merchandise within 24 - 48 "business" hours.
The good news I found this bird immediately available directly from Freewing at $382 landed at your front door. They ship in 3 to 5 business days from China and you should get it in 7- 10 days. I have a email into them now for more details and to confirm pricing and if all is correct I plan to buy directly from them. I'm tired of Motion being the only game in town and their pricing sucks but hey that's just me.. :)

There a scam and DONT buy from them

I think you can kiss your $382.00 Bye-bye or you'll have to fight with your CC company to get your money back.
"Knot heads", huh? What a nice way to ingratiate yourself onto the forum. :Silly: Nobody is putting a gun to anyone's head to do the pre-order under those conditions. It's clearly stated that's what happens and those who don't like it, don't have to do it.

grover-fifty-four, If $17.00USD and a couple weeks of downtime is worth the potential ire of MotionRC and probably some here, it's your money and your time. Perhaps being "new" to the Squawk you might not realize this forum is sponsored pretty much by Motion for their customer base and I believe they graciously open it to all. The advice here comes from those who enjoy this as a hobby and directly from those who design, build, distribute, fly, and upgrade these amazing aircraft. Your end-around tactic if successful will no doubt save you a little money and a little time and might net you an aircraft before those who "Pre-Order" through Motion, but at what cost to your credibility as a contributor to this forum if that matters to you? Respectfully, Elbee
