Nice pic!

I run both my FMS P-51's on a 650 kv as CB recommends and the wings are still on:).
If I recall correctly, the upgrade to V8 had more to do with the landing gear retracts didn't it?
At any rate, they're great airplanes. As for 6s, CB and I both have our FMS P-40B's converted to 6s motors and ESC's from the 1500 mm FMD Razorback P-47 and they perform incredibly! I can't see why the P-51's would be any different.

Welcome to the thread comininhot, I agree with the boys, best 4s option is the 650kv.

Just my two cents, I've run the 6s conversion in all three of my mustangs going back now over 3 years - and I've never had the prop come off or anything. I only recently upgraded to the metal backplate, if it's a concern for anyone (cause some people have had prop explosions but it's way in the minority), buy the metal backplate posted above and you'll have no issues on 6s.

Ah ok i understand now! i didnt see the link in it the first time. Yes the billet prop is the one i was talking about. Earlier in this thread there was a link to it and i clicked on it and it was no longer open but i will have to contact that guy now thank you! Thats exactly the kind of help i was looking for. How can i figure out what version plane i have??

Thanks OV10, big help already.

Look on the RCG P-51 link I had in post #978 and search for the version comparisons/differences.
Am pretty sure someone took the time to document them.

[Comin_in_Hot]

Haha no worries!! im new but i do know the difference there. lol

[mburton47]

Sorry guys, my bad. I thought this was the old gunfighter that they made around 2009. It's a belly lander. Please disregard what I said in my post #968. :Silly:

Yea ive read lots of the props coming off, but the first post under my original post the guy said "use of a 4s batt has been known to rip the wings off"... I was considering doing a 6S if that company will make more prop hubs or i could find one used maybe? Im not sure of the age of the plane thats why i was in question of it. Has anyone done speed check with GPS or radar on one stock then modded??? Ive only seen one guy said his was clocked at 7X MPH?? Im a racer of full scale cars so... i guess i like to waste money to go fast for no reason. Haha

This is because he mistakenly believed your plane was the Parkzone which I further discovered it wasn't and had to make a retraction on post#972.
You've got to do your homework and determine which version of the FMS 1400 Mustang you have cause we can't tell from that picture.
I can tell you though that you aren't gonna rip the wings off even with 6S power, that is unless you plow it through a tree of something.
What company?? making hubs. The prop hubs for the 1400 Mustang are made by FMS and are still available but just not in the Gunslinger green/yellow livery.
If you want a hub that will hold up to 6S you probably want to follow what is going on with Gary @ CustomRCParts.
Here's a link to one of his latest posts on the RCG FMS 1450 P-51 thread.

I can't remember reading about an inherent problem of ripping wings off :Thinking:
Are you maybe :Confused:about the 6S power upgrades blowing the prop blades off the spinner.

[Comin_in_Hot]

Hahah Thanks guys! Sadly/thankfully, i already read almost all of the posts here. My main question was air frame modifications, someone said the wings will rip off at a certain speed? I understand that they discontinued the older version in favor of the V8 models correct?? What were the flaws in the earlier models? is the wing problem something that can be solved with wing spars?

[OV10]

To Comin_In_Hot,
So now that I know that it IS the discontinued FMS Gunfighter Stang and not he Parkzone as eluded by mburton47, here is a synopsis of a power upgrade without reading the years of postings both here and on RCG about giving these FMS Stangs a kick in the pants.
The simplest and most efficient 4S powered conversion is the use of the 650kV motor used on the FMS P-040B Warhawk.
You'll need this prop adapter from the FMS Olmypus motor to keep the spinner/cowl spacing appropriate.
You'll also need to upgrade the ESC to 80A.
Good luck and welcome to the Squawk.
Best regards,

That definitely appears to be the FMS 1400 to me. Look at the size compared to the screwdriver in the photo. Plus the drop tanks with the characteristic FMS vertical seam line, the 4 blade prop/spinner, different exhausts. It gets confusing since it is the same paint scheme as the old PZ model.

[OV10]

Actually I have to eat my words after looking even closer with my spectacles on, it is an FMS :Not-Talking:

[TiredIronGRB]

Actually TI, the main problem is that it is the Parkzone P-51 and isn't even in the same class as the FMS 1400 Stang.
It is a 3S bird with 39" span and Comin_in_Hot actually should have posted this in it's own separate thread.

Oh my...I thought it was one of the 847 versions of the 1400mm FMS:Silly:

[OV10]

The main problem with using a 6S system will be the prop, it won't hold up.

Hello there gents, new to the forum, and pretty new to the hobby. Just picked this one up second hand, previous owner used it a lot and its pretty well worn so its due for a whole new make over! Still nailing down the exact power plant for it and battery supply, id like to stick with 4S because i already have a fair amount of those but not sure if they will deliver the power im shooting for, may have to step up to 6S.

Also, anyone have experience or seen any do air frame modifications to these???? Clipped wings...ect.

Welcome to the forum "comin_n_hot" This P-51 you have is a fairly old plane. Using a 6s batt is pretty much out of the question and the use of a 4s batt has been known to rip the wings off. I have this plane and it is a fantastic flyer but would not suggest it for a beginner. Go to this address and you will find out everything you want to know about this plane. Good luck and happy landings.
