Official FMS 1400mm F4U Corsair V3 Thread

[Cactus Bobby]

I've had the flight line f 8f Bearcat for about 6 years. This plane flies like it is on rails. Pulling it down from the ceiling and wanted to fit it with bombs and Rockets. Does anybody know where I can find something for this bird. I think it would look really cool. Thanks

Is the 650kv motor from the T28 a drop in fit for the Corsair or do you need any.mods to make it fit? I'm currently running mine with the 580kv motor, bigger esc and on 5s. I have the T28 and also running it on 5s with a bigger esc and it's very fast. I would like to get the same performance out of the Corsair

Awesome!

All you need to do is cut some balsa sticks to fit on the underside for both, so the speaker doesn't protrude out of the plane then add some color matched cloth over the hole. That would be awesome!

That's exactly the plan... :)

Found these from Dayton Audio:


She sounds like a warbird again!
The speaker on the canopy lid will be made more "invisible" during the coming long flyless winter days :)

Thanks guys!

The "old school" speakers he's refering to....are the old "2 inch SPL" speakers.....available at Dayton Audio

Interesting........wasn't aware of those buggars, thanx ;)

Hello Kristof and welcome to the Squawk,
I got my V4 MrRCSound around the same time that Pilot Ryan did that vid and mine came with a the transducers.
I believe the"old school" speakers(approx 2-1/2" x 4" size) you are referring to were the ones that came with the Merlin sound upgrade option on the Freewing mustang which has been discontinued.

Hello, Kristof from Belgium here.

Since I really absolutely love my FMS 1400mm P-51 V8 Petie 2nd with the ESS Air sound module in it (upgraded with the TT-25 transducers), I fitted my FMS 1400mm F4U V3 Corsair with the same configuration...
But, as good as the P-51 sounds, that bad does the Corsair sound. I tried several positions for the transducers:
- on both sides of the fuselage above the wing near the CG
- on both sides of the fuselage behind the cockpit (cut out a section on the bottom of the fuselage, where the venting holes are)
- on the canopy lid for battery access and on the bottom on the wing
None of these gave a good sound. I think it is due to the fact that the foam on this plane is very thick, thus eliminating the effect of the transducers.

As I was browsing the internet for a solution, I found a video from our friends at MotionRc with the old MrRCSound V4 with the "old school" speakers instead of the transducers. Now this sounds like it is supposed to.
https://www.youtube.com/watch?v=okcVdJybRQw

But the problem is, that these speakers are nowhere to be found anymore (Googled a lot!)...

Can anyone here help me out?
Because a warbird without a sound module in it, just doesn't do it for me... And I absolutely love flying my P-51 because of it.
The Corsair is even more beautiful in the air to me, but without the sound of the Double Wasp, it is just not complete...

Thanks in advance for any Info,
Kristof

How are you liking the battery that high up in the fuse? I love my corsair but it has it quirks from the factory. It flies amazing in fact better than the p51 but its just anemic and I hate the lack of retract tail wheel. On some models its not a big deal but on the f4u it looks odd. I think its the tear drop rear end.

It doesn't affect it because it is only about 1/2 higher than the average height of the normal angle battery slot. Allows the CG to be more correctly set with adjustable battery position.
I agree on the anemic stock power system. I had transplanted a 580 into and that still wasn't getting it. It now has the 650 from the P-40B when I put the 460 from the 1500 Razor into the Warhawk.
That tail wheel is getting replaced with the retract for the FMS 1400 BF-109F.

Since this is now the official thread am linking two important topics to it regarding the 1400 v3 Corsair.

Oleo Struts mod:

[AkumaZeto]

Flies better than the v8 p51 but meh its just ok. It is grossly under powered and the angle of the battery makes any cg adjustments a major PIA. Lack of retractable tail wheel also make this model not all it could be. Oh and the Korean war variant is not my favorite at all. I know they were trying to shoot for the show plane version that is on the circuit. I know the original pilot died on a crash and his son took over?

[Aros]

Who's flying the V3? What do you think?

I bet it will look pretty good, I'm waiting on the motor mount to come
since my mount for the 4250 doesn't line up so that's why I was asking
did you figure out if your corsair was the one that didn't need any mods
and the mount for the new motor lined up with it or was one of your
other ones? I am crossing my fingers and holding my breath waiting for
my new X mount, let me know if you don't mind. Thanks CT.

Yeah, it actually doesnt look half bad on the
Corsair. Whats surprising is one would think it needs aft weight
to counter, but the CG is pretty much right on with a 3300 6s

Re: fms 1400mm f4u corsair motor upgrade

I ordered one and was surprised to find it is the same length and MOTOR MOUNT BOLT PATTERN as the stock. I used the esc, motor mount, prop., and spinner spec'd for this motor and was able to bolt right on. <quote author="CT">

Thanks CT for the info, since your post was in the Corsair forum I'm hoping that the that this is the one that you said matched up without any mods. Did you mean bolt pattern from the new motors X mount matched the firewall bolt pattern of the Corsair If so I am in business?Thanks in advance CT!!

Re: fms 1400mm f4u corsair motor upgrade

Greetings,
I have retrofitted all my 1400 birds to this new power package, and all fly much better and needless to say faster w/ almost unlimited vertical. I am currently traveling and do not recall which ones required the specific mod for this upgrade. One of the birds required absolutely no mods as the 6s motor fit in the same firewall and had the identical screw pattern. You will likely need to modify the existing firewall/motor mount with 1/4" ply glued to the backside of the existing plastic mount. Due to the size of the opening, you need to cut the new oval shaped ply into 2 pieces in order to place both behind the existing and cement in place. This way the new firewall will not pull out under the increased pull of the 6s motor. I use 1 1/4" course thread deck screws to anchor the motor plate to the firewall. You will need to ream out the new metal motor mount to accept the larger deck screws.
The system will cause an approx. 5mm larger gap between the spinner and front of cowl. In order to keep the same original gap one would have to remove the existing plastic firewall/mount, a major mod I found not necessary but this is a personal preference. Also I found the new 2 blade high speed propellor will work with a 70a esc, but I use an 80a for a cushion. Be aware by using the original 4 blade prop set up will cause an increase in load and will pull in excess of 80a, also will not yield the same speed as the 2 blade speed prop.
Obviously this mod will not yield an authentic or original look due to the increase in gap as well as the 2 blade prop., but I use it primarily for increase in performance. Unfortunately once you fly this mod. you will never go back, its a kick. I found the power package is well tuned as the lipo pack, esc, and motor all stay well within temperature limits even on wot flights. One more item I added was an extra cooling scoop either on top or below the front fuse which directs air to the lipo pack and/or ESC. I used the plastic wing servo covers I collected over the years which make a very good looking air scoop. Hope this helps.
