Robart pin hinges are what I have used, a good upgrade.

The best decals in my experience are from flightlinegraphics.com
Nigel does a complete set at 1/5 for the FW190. I always use him as his prices are good and service excellent.

http://www.callie-graphics.com/ will make anything you want. Give her a pic and tell her the size and bam....and shes reasonable on price too. She does mostly vinyl self adhesive I believe. Not sure about dry transfers.

Phil has great products. I own some of his goodies. The decals he sells are from Tailormade.

Thanks Mike, I used a XYZ 53cc twin mounted inverted with homemade exhausts. Great little engine and fits the small cowl (just!).

Hi Everyone

I see that some hobby stores are now selling the scale spinner for this aircraft from ESM. Has anybody seen one and if so could you please post a picture of it. I am quite keen to see if the scale profile of the spinner is correct.

I wish ESM would release the relevant spinners for the aircraft when they come onto the market. I have a 50cc P40 and finding a spinner for this aircraft has been a major problem as well.

Kind Regards

James

Hi guys, I have practically read through all the thread and 2 thumbs up for everyone who contributed, really. Great info and many, many good tips.



I my self am an "electro" guy and would like to make this bird electric, so anyone already done it here, or is there a different thread? I am just starting my ESM PC-21 project and as all the necessary gear is already in (appart from the scale prop) not bad to start thinking already about the next project .



Reading that the front weight is a bonus I am considering going with the AXI 5345 (still undecided if 10S would be enough or will have to go 12S) and the Benedini sound system. So theoretically speaking I can have some 2,6-2,9kg of gear at the front which should be OK.



For my PC-21 I will use AXI 5330 F3A on 10S because I do not expect it to go over 8,5kg and that should be more than enough but this bird will end up closer to 11kg so a bigger motor is a must, at least that is how I see it.



There is also a new version of ESM E-tracts for this bird which should be up/down in 10s, so definitively worth considering.



My friend Mirce has put this WW2 bug in my head, probably some of you already know him and the birds he is making, great stuff.

Velco,

I am just finishing an EP conversion on this ship.   Going to fly on 12 cells (two six cell 5000mah packs)     Using the Rimfire 50cc  equivalent turning a 22x10 APC prop.  Castle 160 AMP ESC.  I have used Sierra Air retracts.
CG is looking very close with the two big batteries placed in the area directly behind the firewall  (not under the gun hood) Cutting a hatch into the fuselage was a precise job but worked out very well.  So far the project looks like it should be a winner from a power and wing loading standpoint.
I will post a report after we get some flying weather.

Regards,

Doug Andre

Andre, would you mind showing your electric setup? I'm slowly getting into large scale electrics and I'm kinda jumping right in. I recently bought the 50cc rotomax but have yet to purchase anything else for my second ESM 50cc BF109. I almost didnt go this route due to electrics costing soo much just to get a few flights in but my feet are wet now! Any information would be much appreciated!

Extended to everyone! thanks

Ram,

Glad you are considering going electric!  I have been all electric for two years now and have not looked back. 
For me scale and EP go together.   The lack of vibration and simplicity of install first attracted me.  Digital sound has now arrived and all my needs are being met.     Cost is still higher for EP but that is slowly changing.

I will post some photos of my conversion  ASAP.

Regards,

Doug Andre

Andre great info! Looking forward to your mods, especially the battery hatch! Please also post your flying weight.



That motor looks mean, and kV is really good. I do not have any experience with Rimfire motors and generally I stick to AXI for bigger motors. I was looking even at Hacker A80 but it is heavy and expensive. AXI 5345 looks OK and for me the cost would be only marginally higher from a 50CC Rimfire. Looking forward to your flight reports with that motor, it looks to be an interesting option.



My AXI 5330 235 kV on 10S was spinning a 20x12 Turnigy Light Eletric prop at 6.900 revs and 75A which was very good. Turnigy LE are very good, just slightly less powerfull than APC but some 8-10% less Amps demanding.



For a 11kg bird on 12S and 230kV my guess is that 21x12 might be better solution or even 20WEx12.






@ Ram



My suggestion to you if you are just starting with the electrics would be to go with HK batteries (6S Rhino 4.900mAh 25C), HK 100A ESC and a high quality motor (my favorite is AXI or Hacker) around 1000g and kV 190-230, XOAR props seem to be a good choice. If you have any doubt I will be glad to answer.






This is the sound system I was talking about http://www.benedini.de/Home_E/Products_E/products_e.html



and they have FW sounds in their library!

Velco,

The AXI 5345 is a beast of an engine, I have one for my BT Spitfire. One thing to consider with the use of the Benedini sound system is that you need to have area's for the sound to exit. Planes with wing radiators work great like the spit or the 109, but the FW doesn't really have any of these types of area's...what have you come up with? Here is my Benedini sound system in my Fliteskin 109F. I've one speaker under the chin in the oil cooler, and the second I put into the wing and put porting out to the radiators.

Dont get my wrong, I think sound systems are great, but for the cost you need to be able to hear it!

Mirce seems like a great guy to have around....bet he's alot of fun.

Hi Casey,



you really got the point about the sound system. Currently I am considering couple of options but the one that might be a possible solution is 2x40W amp with one speaker at the firewall behind the motor. For the 2nd speaker that nice fuse would have to be cut at the underbelly but masked with some adequately painted net. At least that is the idea right now.



Theoretically both 4" speakers can be fitted on the firewall and powered with a 2x40W amp or, a 50W mono amp powered via main bats and one 6" speaker at the firewall, that should make enough noise I hope.



Unfortunately there is not many other solutions without cutting the fuse. I dont like it either but ...



Yes Mirce is loads of fun and he is the "guilty" person for me jumping on the warbird train. So far it was IMAC and F3A but the time has come.



Actually before deciding going down this road with Dora I have asked Mirce to help me with the build because he is really an experienced builder.

Mirce will try to organize this year a local Top Gun. We are a small but growing RC community .

sounds like you have a good plan...I am trying to keep the scale lines on mine so that was not an option for me(cutting the bottom of fuse and covering) I hope mine puts out enough sound, but as it is, it will be what it will be lol...

its a good thing Mirce has corrupted you in such a way....warbirds are soo much fun, I'm sure this wont be the last for you!

Hey guys, is this topic about Dora or Mirce
I'm just kidding...

I'm very happy to have one more "warbird victim".
As Veljko told, our warbird community, here in Serbia, grow every day, so this model on electric power and sound system will be something new for us here.
Cant wait to see it live...

All the best

Mirce

Played a bit with ecalc and my conclusion is that for an 11kg WW2 warbird a motor of around 1000g, kV 190-200, 12S bat and 21x13 give optimum performance. My criteria for this conclusion were:



1) Static thrust 50% higher than the flying weight



2) Max speed not less than 85mph or 135kmh



3) Max Amps preferably below 100A in order to get some reasonable flight times as I consider 5000mAh as a common bat capacity



So my choice would be an AXI 5345/18 HD on 12S Rhinos 4.900mAh and Xoar 21x13 F3A prop. This combo should make some 100A, 16kg static thrust and 145kmh/90mph with plenty of reserve thrust for any maneuver from cruising speed.



I have some 5 years of experience with the electrics and have really learned how to obtain a reliable maximum necessary for almost any type of plane.

Thanks Doug!

I can see that you have made some additional holes in the firewall Ipresume for battery and electronics cooling. Where did you put the air exaust?

Velco,

Several holes were added to the firewall for wiring and cooling.    Some air may escape around the tail wheel opening.  I intend to cut a cooling exit in the bottom of the fuselage just behind the wing.   I will test fly first and judge how large the hole needs to be. The Motor and ESC will have good air flow under  the cowl flaps per old glow practice.   I hope the battery will not get too hot!
