My concern is derived from my CMP P-40 (50) experience. I understand the big birds fly great, but nobody has had any success with the 50 except some guy in Norway that did an electric conversion. No offense to electric guys, but [:'(]. I think I'll do the wait and see thing with the Messerschmitt......although, I do like the way it looks. Then again the CMP P-40 (50) I had was the best looking plane I had. All the way into the ground......

The only real reason ppl had so much problems with the CMP P-40 50 size was due to the CG being printed wrong in the manual. It was for the 140 size which obviously made the 50 size very tail heavy and virutally unflyable. I have the CMP Corsair and it looks decent. The parts seem strong, the fiberglass seems decent with no cracks in it.
I'll definitely get the CMP ME-109.

Alex...is there a way to pre-order the CMP ME-109? I want one from the first batch and want it at my door as soon as possible.

I agree, Alex at AK is the way to go for these planes.

His customer service is very good and responds rather quickly.

I wish I could say the same about another place that I've frequently complained about but that Very Quickly just degraded into finger pointing.

It's good to know we now have a starting point for pricing... i'll try and get onto the Aust distributors again this week and see if they have any more info, but i'm sure AK-models is at the sharp end of the story

I too was a bit annoyed with the poor rendition of the Fw-190 hence the kit bash, but this 109 looks pretty close to me so far without being able to "hold" it.

If nothing else it should be a good starting point for bashing.

Thanks

The guy in Norway did a conversion on the 73" size , the small P40 is a very good flyer but 100% a real warbird, not at all like a H9P40 , it needs speed and 25% CG from your maximum cord .
The 70 and above new releases starting with the P40 are some of the best on the market , looks like this new plane has raised the bar once again

I showed the pictures to my wife of the CMP ME-109. She seemed pretty excited too. She marveled at the amount of detail on it. We both like the German planes from WWII, but she doesnt fly............YET!!!!

Mate your a lucky man.... my wife reckons they all look the same to her!! she does try. for my birthday she bought me a plastic model of a corsair because she had heard me say that name recently and a wildcat model because she liked the name i do still build plastic models, so it was a nice of her.

I'm starting to loook into color schemes, because i am thinking of flying her in standard trim a few times before she comes into the shop for the bash!

Thanks

Mine will probably get slightly overhauled as well regarding paint scheme. I'll see when I get it, but am thinking of Hartmann's winter white version with the tulip nose

KentuckyColonel

Mine would:
One: Not look at it
Two: If she did accidentally see it, roll her eyes
Three: Say, "WHAT?!?! ANOTHER ONE?!?!?"
Four: Kill me
All would be worth the risk if this one is a sweet flyer!

I am really, really considering doing this one as an electric. Buddy of mine with a H9 P-51 1.50 size put a power 160 in his plane running on 12s and an 18x12 prop. Even though he limited it to 75% throttle, it still ran rings around my H9 1.50 P-51 with a saito 220 in it. I mean it really moved out and was capable of absolute vertical climb while also doing rolls.

So, instead of buying 2 new 5000mah 5s or 6s batteries for which i cant use in anything else, Im considering using 8 x 3s 2200's set up in the following manner:
8 x 3s 2200's
making:
4 sets of 2 x 3s 2200's in parallel to produce:
4 sets of 3s 4400 capacity

Then, 2 x 2 sets of 3s 4400 serieled together to produce:
2 sets of 6s 4400 capacity
which would then be serieled together to form:
1 x 12s 8800 capacity
================================

There are a few problems I have with this though:
1) can only fly the plane once per day unless I sit there for several hours charging 8 - 2200 3s batteries
2) I have 6 - 3s 2200's now, so would have to buy 2 more for a cost of about $190 (assuming thunderpower since the 6 I have are that brand)
3) Cost of electric motor is $63 and the speed control is $109 (from hobbycity.com)
4) so total cost of the electric setup would be $362. Buying say a saito 180 would be the same price and would allow mutiple flights...except cost of fuel
5) I did an electric setup in my Kyosho Corsair running a 6s 4400 setup(4 x 2200 3s batts). I only got 5 mins of flight time, however, I had the timing a little advanced for a lot of power. Lowering the timing would provide maybe an extra 30secs to 1min of flight time and lower the watts from about 1100 to about 975. With double the capacity(as shown above...Id get a flight time of 10 mins. But, the motor for this CMP Me-109 would be larger then the one used in the Corsair. That one was a 1200 watt motor and the one I have in mind for the ME-109 is a 1900 watt motor.

I do have a saito 125 available right now I can use in this plane, just not so sure if that can pull the overall weight of the plane. The website says 13 pound flying weight, but Im going to assume a 14-15 pound weight if using electric.

So...what to do? Cost of nitro fuel is going way up apparently because the china factories arent making it right now for a couple reasons...polution and I think the Olympics.

Another simplier option is this:
Using 3s serial deans(meaning you serial 3 batteries together):
2 x 3s serial
each 3s serial includes:
1 x 3s 2200
1 x 3s 2200
1 x 4s 2200
total: 10s 2200
parallel two of those together for:
10s 4400 capcity.
This requires no further battery purchase as I have enough 3s 2200's and a few 4s 2200's to do it, but, the capacity is a lot less and also the voltage is considerably less at 10s instead of 12s.
If I did this, then Id be back to the 5 min flying time estimate and still only flying once per day....not really what Id want.
At least with the first setup(12s 8800 using 8 2200's...I could also plug in 8 x 2100 pro-lites for 8400 capacity for a 2nd flight(but would have to add weight since pro-lites are lighter then the TP extremes used in the 2200 setup).
So, this is the amp capability of the 2200 setup....each batt can do 50+ amp continuous(with a 100 amp burst)....so it would actually work out to a 200 amp output capability.....the motor itself would be pulling about 70-75 amps so each battery would only be required to push about 20-25 amps(half of its ability)
On the 2100 pro-lite setup.....those can do 30 amp continuous(but get hot if doing so) and thus would provide a 160 amp output capability using 8 in the 12s serial setup outlined. Each batt would be pushing 12-15 amps in this case and thats about right for keeping pro-lites somewhat cool and happy.

Dude you lost me at "I am going electric " not that I dont think that is a great option and the 73" P40 was done to perfection as an e-bird by the guy in Norway , but for some of us dummys- the conversions , packs , combos ect ect ect is why we dont go big in e-flight - I defer to your expertese , figure it out for the few closet dummys (me)and let me know the best results
so I hope you publish the results

Or you can make a 12s2p A123 pack to fly this bird. Then split the pack to two 6s2p A123 packs via a shunt switch. Get two lead acid batteries in series(24 volts) with 14ft of 18 gauge wire to drop the charging current to 20amps, and you will charge the pack in less then 15 minutes, and not have to wait an hour for li-po's.
You could also leave the A123's in the plane while charging.
You don't have to wait for the batteries to cool down either.

I should be more into my electric models too but i do love the sound of a glow/gas motor up front..... if only those sound modules would come down in price

No i don't have any experience with the A123 cells but for a 12s2p pack would set you back 24 A123 @ $17 USD =$408 add the motor/ESC @ $172 give you a total cost of $580 for the electric setup.

On the horizon website they have the Saito 180 for $400 so although the electric set-up is a little more sto start with, it's not all that much more, and if you could spin an almost scale sized prop you would beat the gas/glow setup any day of the week!!

Might be worth looking into considering that i don't have a engine for the 109 yet.

Thnks

The Saito 180 is typcially $349 in good hobby shops . I think you also have to consider weight , is the glow version lighter and by how much .
I like the eflight option because you miss that long process of engine break-in and I like the ease of field start up vs glow

$349?????[X(] You guy's are spoilt!! that engine in Australian hobby shops is over the $700 mark my O.S. 1.20 fs Pumper retails for around the $650mark here.

Thanks

I would agree with you that the cost of going electric at first seems astronomical, but you see I use these two 6s2p a123 packs in over 15 planes, some with the single 6s2p setup, and some with the two 6s2p in series to make 12s2p setup, which in reality has brought the cost down if you do the math. The motor for this plane will cost you no more than $50.00, the ESC(speed controller) will vary in price, but if I go to Hobby city I can get a 12s ESC for around $100.00 or less.
So in reality, I would only spend $150.00 for an electric power plant if I were to go with this plane.
Oh, I only spent $10.00 a cell for my A123's. I know the price has gone up a bit since, but I still think it has some advantages over Li-Pos, especially the less than 15minute charge time, and then fly again.
No cost for glow, or gas, and the Go-Green people will love you, if thats your thing.
Today I flew my Sportsman Aviation Corsair on a 6s2p A123 pack, flew about 7 times, charged it while I talked with the other members, then went up to sortie again, with lots of maneuvers flew for 8 minutes and had plenty to spare for any go arounds.
There are plenty of guys using this, I'm not going against anyone using Li-Pos or glow or gas. I'm just saying the other option is there.

I agree that e-flight is a great option , I was eyeing the new H9 B25 and if purchased I will be going electric . As far as hobby city have you found your batterys to be consistant ?

Corsair 29

I Haven't purchased my batteries from Hobby city, just the motors and ESC's. I get the A123 cells from Ebay, Dewalt DC 9360 battery module which has 10 A123 cells in it. Then I split the batteries into the configuration that I want, and attach a balancing connector. After three or four cycles of the new cells balance out too 3.6v per cell.


I tried to post the link for the motor and ESC from Hobby City but it didn't work.

Anyways the ESC part # is TR_S100A-HV (Turnigy Sentelion 100A HV 2s - 12s)

The Motor is a TP5330-8T (Tower Pro 5330-8T)

I have used the above setup on 5 different planes with great results.

If you really want to add the real engine sound ( Daimler-Benz V12)then you could go with this, from Aero Sound:[link=http://www.aerosoundrc.com/products.htm]Aero Sound[/link]
Comes with machine gun sound too

AK Models

I will offer pre-sale on this kit just as I do now with other planes that are coming in ~10 days.
Once container near destination port I can estimate that it would be at our place in a week-10 days.
I have 80 kits coming and I do not think they will sell in few days, if they do it would be best selling plane I ever had!

KentuckyColonel

Quick question. What are the stats on this baby again. I can't locate them, although I know I saw it somewhere before.

kahloq

I got that same esc on the way, but the motor I have is an HXT 63-64 A 230kv motor(basically a turnigy).

I'd really like toi find some place that can put tyhose a123 packs together for me

What will the price of this ARF be?

Vintauri

My Feedback: (25)

Do you have a Batteries Plus in your area? They might be willing to do it as they make custom packs at most the shops. Otherwise just do some reading up. It was not that difficult for me to make my 8s packs and add balance plugs.

Typically the CMP list at $4000 each , then thanks for excellant marketing we get 500% discount and it ends up at $279 intro , then depending on the amount or flow in the market we end up at $219 thru $249 on new CMP planes , at leaste that was the story with the P40
