FYI the Full Scale Spit flaps come down about 80 Degrees. So nearly straight down. They are pneumatic so they are either up or down. Try more flap for a slower landing

Hey AZ thud keep me posted on how your CG works out
H9 is doing such a great job on these warbirds and as an electric flyer I love that some of the warbirds are setup for us

just loving my H9 30cc P-47 electric converion totally bummed they stop making it.... such a great plane not sure why it went away
Digging this spit and it may end up in my fleet

What prop do you think you will run and how many watts are you pulling on your 12s power 160?

thanks

+1 on the 12S Power160 setup. This motor has really good value/power ratio in my opinion

AZThud

I am using some large batteries, 5000 6 cells, they fit in the compartment but it is tight, the batteries extend well back into the hatch and end at just about the c of g. The net of this being I had to add a considerable amount of weight to balance the plane. With the wheels down it took about 8 ounces. I know this is wrong but I did not weigh what I put in with the wheels up, I would say about double. This has the C of G at or close to 4.75 inches. Then I ran into another glitch, my spinner shook like mad, so I pulled it off and tried the spinner from my LA-7 its just over an eighth of an inch smaller in diameter and lighter, that has it smooth as glass with a 16X10 doing about 10,000 rpm. I will be looking at the balance again tonight as I really want to get her flying this weekend. Will let you know.

Cheers

Predman,

Do you have any picture of your setup? I went with the DLE and I was wondering what you did for the choke and throttle set up. Also, how bad is chin scoop cut up? It looks as though the exhaust from the DLE exits right at the beginning of the chin scoop. Any pics would really help.

Thanks

I am going to try and snap those pics for you, I got some video from todays flight. trying to edit so that may take some time. I didn't put a choke set up, I use my starter w a silicone cup so it doesn't eat away the spinner paint, starts right up. Afet the first start I can flip it. The exhaust is before the chin scoop so I didn't have to cut any of that. I did however, put a heat shield above the muffler and below the carb to cancel out any heat issues. gathering pictures now.

Someone in my thread at rcgroups used the throttle servo in the stock place and used a flex cable and wrapped around to location.see http://www.rcgroups.com/forums/showt...2121941&page=2

Maiden Flight Report.

Got mine in the air, put on two flights and both went well. This is the setup:

12S 5000 mah 65C Thunder Power batteries, 80 amp Castle HV ICE running an E-Flite P160 Static Amperage just over 60 amps and 44 volts with a 16X10 prop.
I have the batteries all the way up in the battery compartment and added another pound or more of lead to the cowl and on the motor box, I also have a 2100 mah 3 cell LiFE battery under the cowl this brought the all up weight to 20 pounds even. With this set up I am getting over 100 watts/pound and there is nothing wrong with the vertical or the speed. The C of G is at 4.75 inches and with the gear up, when flying inverted very little forward stick is needed for level inverted flight. My controls were set neutral and I need a small amount of down elevator and some aileron trim for hands off flight. With the gear down the weight does shift forward, as a result some back pressure is needed to keep her level. I have my flaps set to about 80 degrees and with these down and 4% down elevator mixed in the plane balances out again and flew nice and slow and was easy to control. I set all my "normal" control throws to the max settings in the manual and never felt the need to reduce the rates.

Takeoff was easy to control as the long fuselage really smooths out the rudder, you will need a good dose of right rudder to maintain a straight track, but as the speed builds you can come off the rudder. This thing fly's beautifully big loops are easy, rolls smooth and don't need much if any elevator input. I did one stall and it was a none event, having said that it took 3 try's to get her slowed down enough to land, even with the flaps down loosing speed is a gradual process, so if you fly off of pavement expect to use a fair bit of it to get it down and stopped. On my second flight there was a bit of a cross wind and it wanted to turn into the wind, as the speed bled off, I was a bit heavy on the rudder and it over corrected, with the narrow gear the scraping sound of the wing tip was soon heard. Overall the first two flights were nice, 8 minutes on the first flight had me adding 3000 mah to the packs before the next flight. The second flight was the same duration and there was plenty of power in reserve.

Overall we have a winner!

Cheers

Quick question. Is that 80 degrees of flaps accurate or is that a typo?

Mine just rolled in today.

33GX powered.

BobH

My Feedback: (2)

It's accurate. Flaps are nearly straight down when deployed.

Good Job AZ and congrats on the maiden, thanks for the report
sounds like she doesn't need much power to fly well

BarracudaHockey

My Feedback: (11)

Ok thanks! Sounded like glider flaps, I've found most powered planes don't get that much throw but that will definitely help in my tight field.

I had found a Spitfire maintenance video from the 1940's that showed the flap selector. It had an 85 degree marking.

flynfish67

Good picture showing the degree of flaps on the full scale. Thought it might help the discussion.

AZThud

Actually its a bit less than scale, 85 degrees is what they left the plant with, essentially they are brakes, I don't think there was any aerodynamic lift at all, Also there is only one setting on the full scale, well I guess two, up and 85 degrees. I put two more flights on today and again I had to go around each time as I was going to fast, slowing the plane down needs to have less power than I am used to, this thing will really float, and float and.... well float :-)

Ron as far a power is concerned it has lots, over 1 to 1 so scale flight is easy, half power works well and full throttle gets it somewhere in the 85 mph range. I have a 12 pitch prop I can put on and that had my LA-7 clocked at 104 or so, but that was too fast for the LA to look right and the speed on mine is just fine.

Cool.

I've owned Mustangs and Corsiars, but this is my first Spitfire and I'm excited.

The E-Flite retracts look very VERY stout. I'm sure I will have it on my stand just cycling the gear cuz they are cool

AZThud

Hi One of our club members took a video for the club of the Spit, it was a bit breezy and based on the takeoff you can guess which way it was blowing. (That is my excuse for such a lousy TO ) I might have mentioned it likes to float if you come in too fast.... Oh and the interview at the end was not my idea!

Great flight.... power 160 on 12s sounds great, nice prop rip
you weren't kidding about coming in hot and floating... that baby was going for days.

I've used crow on my jets, never on a warbird I wonder if it would help or make it want to nose over to much

might just need a long flat approach
thanks for sharing I love it

AZThud

Thanks guys, Typically I approach with as much drag as possible and keep the power on until after the wheels touch, With this one I am using to much power and need to reduce it a bit more and do so sooner. My next flight will be exploring the slow flight characteristics of the plane, at altitude, and based on that I will also change my approaches. This weekend I will be flying my Jug, unlike the spit, it slows down pretty fast :-)

Cheers

Guys the locally model shop have got some in and I am really tempted. I was thinking of the Saito FG 30 as the power plant, anyone used one in a warbird. I really like the sound of four strokes and was thinking of going glow but some one suggested this engine which is petrol. I have read various reviews but just wondered if anyone on here has used it. ?

I'd put the 33GX petrol in it.

I'm shooting for this coming weekend, or even better, i like to do my review test flight during the week w/o the peanut gallery, so maybe Friday

azthud thanks for sharing. That is the first EP video I have seen of this plane. Looks great.
