Official FMS 1400mm P-51D V8 Thread

G'day Grossman,
I can not even begin to comprehend that kind of temperature. It simply does not compute in my brain.
I am sitting here right now with the aircon on and the fan blowing cool air on me.
A cold soft drink with half a glass of ice is just in reach as well. Yes, it has been 38*C here today at 80% humidity. Very sticky and uncomfortable.
G'day Crashcanuck,
Flying of grass depends a bit on where one lives.
Our runway here is grass [I have never flown off a hard track yet] but we cut it very low and the grass is a 'running' type that covers evenly and helps smooth things out even better. You would know the shortness of a golf green, well that is us.
It also helps that we have done a lot of work on our strip by professional leveling, a sand base to aid with no surface water even after the heaviest of rain we can fly within minutes of the rain stopping, and a heavy rolling from a road roller. [cost over 100k all up after bovine vandals had gone to town on our strip]
Add to the fact that we have several hundred tonnes of clean fertile topsoil over the sand base and you can imagine how nice our grass strip is.
This is not just our lot either as us Australians cut our grass really low compared to the way grass is cut in the USA.
Your grass will put more strain on the gear as the US tends to call short about 25 millimetres or so. The grass does not even come over the tyres on the tail wheels of my 1400mm FSM Mustangs.
If you guys in the States would cut your grass lower you would not have as many problems! [please tongue firmly in cheek there, mate]
I used to sell ride on lawn mowers and I know the difference between the cutting height of the US machines and the Australian machines. It is about 3/4 of an inch between the lowest heights. And we scalp the worms!

On New Years Eve, I finally got to put flight two hundred on my Shangri La and adding that to the other two machines [Duchess Arlene and BBD] having well over the hundred and fifty mark each, it is not too bad of going I think. Plus fifty each on my other fourteen models in the hanger. Plus family commitments and work and ....
It should be also noted that the only repairs on this machine have been swap outs. The side frames for the landing gear were swapped out at flight number fifty for the metal units and the 540kv motor was swapped out for a 580 and latter for a 650. Other then that, I have not replaced any item due to crash damage or failure......oh, hang on, I did replace the bearings in the 580 motor after five flights, and I kicked the outer gear door once and broke it, but that was my stupid fault for not looking where I was going.
I also had some bronze phosphorus bearings made for the wheel axles to prevent the e clip from cutting into to the wheels. I did this for all my models.
I then coated them with teflon and now I have trouble stopping the models on the runway. But the take off run meets very little resistance from friction.

All in all, I have a ball with this hobby and I have made some life long friends from it. And this bunch of model flying lunatics has to be one of the best groups of people going around.
So with that, I wish you all a HAPPY NEW YEAR and a safe, worry free 2018.

Regards and respect
Daryl R Woolfe

Lucky Guy! We have a foot of snow and minus 8 freaking degrees F here!!
I'd recommend the CNC Smallparts metal retract sides if you're going to do some gear work, well worth the price.

Well I removed my broken retracts today and replaced them. I found that the broken retract did have a bent connecting pin. So I must have hit something on the runway. I think it was an ant pile. Anyway, in all fairness to FMS the retract was not at fault.
Also, whoever at Motion was responsible for getting those retracts to me ASAP is to be commended! <Salute> The 580 motor won't be here till Tuesday. But that's ok. I can fly now.

Hoping to fly Petie this weekend but the temps here are falling fast.

Grass is generally going to be a little harder on landing gear over the long haul compared to asphalt. Our runway is built on an old garbage dump site and one part in the middle continues to sink. So there is a good size dip you have to try and account for.
I won one of the Rochobby hopped up Corsair's at a flying event last summer. On the third landing which was pretty normal the right side main gear collapsed. I noticed the lights were going on and off as i walked up to it. Turns out something overheated in the retract and fried the wire in the wing, but it also melted the wire for the flap, aileron and wingtip light into a total mess so I know what you mean about quality of products. I'm lucky the whole plane didn't burn up.

Mustang formation yesterday. My stock bird and another smaller one in formation. From my flying buddy's channel

Nice to have a neighbor (neighbour) like that!

That aluminum spinner is a nice looking piece and will likely be in my future plans. Funny thing is my neighbour could probably build me one if he had the time. He has a lathe and milling machine in his garage and scratch builds some beautiful works of art planes. Some of the aluminum landing gear he has made just blow me away. I will have to have a talk with him about that, could probably just measure up the stock plastic one and go from there.

I'm already setup pretty well with 6s packs from either other planes or helis and would like to stick with what I have. So will that spinner work with the stock 4 bladed prop setup or is it meant for a 2 blade?

It is designed to be a drop in replacement to work with the stock blades.

[Grossman56]

Good advice! If you want to go with the best 4s system, you can put the FMS 650kv from the P-40 in with a 85A ESC, with or without the prop mod. My P-51B is flying with that and its great!
Great info on the spinner as well guys, I'll bookmark that one. I've got the P-40 all rigged up with the FMS P-47 6s motor and ESC, I've seen Charlie's fly, simply amazing!!

Welcome to Hobby Squawk Crash! I doubt the 1450mm prop assembly will hold up long on 6S...don't ask me how I know:Bomb:

Ditto. Get the aluminum backplate from customrcparts if you want to run 6S: http://www.customrcparts.com/index.p...roducts_id=217. Definitely worth the money to avoid a spinner explosion.

Hey guys, I'm new to Hobby Squawk, first time posting. I just bought my second Mustang the other day, this one is the 1450mm Shangrila ver. My first was the 1700mm red tail version which sadly crashed beyond repair a couple of summers ago. I plan on putting the 85amp ESC out of the 1700 and the 4258-550kv motor in the new stang and run it on 6S. I read that I should not do the prop mod with this setup, is that correct.
I'm looking forward to the build and mods over the winter. I picked up some skiis today for the Beaver for our Jan.1 frosty fly as there will definitely be snow on the ground this year and calling for -10C temps.

Big Beautiful Doll!
Sorry, I've always used that for her, didn't think anything of it.
Speaking of which, she's about to get an upgrade from her 580kv to a 650 kv that came out of the P-40 because I've gone 6s on the P-40. Got the motor and ESC from Pilot Ryan's P-47 that got totaled at Nefi. (BTW, guys, the easiest motor conversion I've done to date)
To mount the 650 takes a bit of drilling as the motor mount has a different bolt pattern, but not a big deal, I've done it on my FW P-51D, Flightline Bearcat and the FMS P-51B, helps quite a bit.
Here's how she looks, did some cockpit mods aw well. Believe it or not, the first RC plane I ever bought....

She's a sweetheart!!

It took me 45 pages of reading to figure out what the heck BBD was!@#$

Yessir bone stock. Gonna take Petie (aka Ole Blue Nose) out today for some more test flights with the boys. I'll report back. Yesterday we had a gale blowing. Hopefully today the wind will die down a little.

[Grossman56]

Looks great Seaviper, are you running the stock 540 kv?

[Shirty]

It just happens, I can't help it ;)

[boomer108]

You just couldn't resist could you Shirty.:)

[Shirty]

of course it does, it's a blue nose! Lol, grats mate

Maidened my FMS P-51 today, Christmas day. The weather was indeed frightful...for a maiden anyway. Constant wind at 10-15kts and temps around 40F. My wife gave me the P-51 for Christmas and went with me to take photos.

Flight 1: easy takeoff with a howling crosswind. But I soon realized the bird was acting tail heavy. Got her under control and landed. It turns out that I had forgot to re-adjust the tail linkage after doing the Z-bend mod and gluing in the pushrod guide tubes. Pilot error....

Flight 2. same battery, no recharge, elevator properly aligned to stab. She flew and handled the wind with no problem. Stock power, Admiral 4s 3600.

I am sure I will put many hours of flight time on this bird. What surprises me most about the P-51 is how well she penetrates the wind. Landings and takeoffs are really easy even under pretty good crosswind conditions. Good ship.
