CMP BF109F BUILDING THREAD
 

UPS notified me that the CMP BF109F will be delivered tomorrow. This feels just like xmas eve, except that Santa doesn't arrive till late afternoon.
My plans for the bird are as follows.
Engine: OS 1.60 2 stroke inverted with onboard glow, and from the look at the aussie's pics, cut slots in the spinner for a 3 bladed
MS prop.
Radio: Futaba 14MZ
Gear: Robostrut Mains, Robart 85 degree throw, with retractable tail wheel. The 14 allows for a retract time from end to end of
25 seconds.
Pilot: Blue Box Desert pilot.
Details: There is a website that has a plethara of pics of the 109, plus I have the book about "Assi" Hahn and the several
airplanes he flew.
So who is going to get the ball rolling?

No Way!!!
I can't believe that plane is finally on the market... I'll be following your thread as closeley as my addiction to this "hobby". Keep us informed at every move.
:D

RE: CMP BF109F BUILDING THREAD
 

Just got mine today. I ordered it a month ago. Seems like I`ve been waiting for this thing for over a year now but it was worth it!. The box it comes in is huge! When I opened it I found that everything was very well packed. I unpacked everything and found that all the parts are perfect and the covering is nice and straight.This plane is huge! I think CMP really out did themselves on this one. The paint finish is very flat and the markings look pretty good. Not 100% correct but those can be reworked. The split flaps are cool and have a rounded front edge where they tuck into the wing.

All in all it`s a nice kit that will be fun to build and to add all kinds of scale details!

RE: CMP BF109F BUILDING THREAD
 

Dude, please post some pics...i can't wait to see it!

RE: CMP BF109F BUILDING THREAD
 

Spent the day researching the plane. The closest I could come to the CMP version was ship #5 Werke Nr.5749 that Hauptmann"Assi"Hahn flew when he was Gruppenkommandeur of III Gruppe, Jagdeschwader 2 "Richtofen" St. Pol, Northern France.
This is detailed in Profile Publications #184, and the book by Jerry Crandall, titled, Major Hans "Assi" Hahn The man and His Machines.
The major differences are the yellow cowl and rudder color, the white and RLM 70 Black-Green spinner,unit badge and personal emblems, fuel type, swastika,and 31 victory markings on the rudder.

RE: CMP BF109F BUILDING THREAD
 

Mine will be arriving on Monday the 11th. It will be an electric conversion using a 1900 watt turnigy 6364-230 outrunner on 10s 4800mah lipo with probably a 20x11 prop.
I already have an Eric Hartmann Dragon/Blue Box 1/6th figure that will be the pilot.

RE: CMP BF109F BUILDING THREAD
 

I think i'll have a 35 or 45 cc gasser in mine~ [8D]

RE: CMP BF109F BUILDING THREAD
 

geebeezracer,

Please post pics and any other feedback, such as distance from firewall to prop hub, and cowling dinensions so we can figure out what engines will fit.
Thanks! [8D]

RE: CMP BF109F BUILDING THREAD
 

how are the retract mounts put in? are they close to the skin on the fuse end and set into the wing on the wing tip and to allow for the angle of the strut in a me109?

what are you guys planing to use for retravts? are you going to attempt to get the scale oleo angle?

RE: CMP BF109F BUILDING THREAD
 

I got mine yesterday. There was some damage on the wing saddle on one side and its not minor

RE: CMP BF109F BUILDING THREAD
 

Not minor, meaning the damage was bad ? was it packed poorly or the shipper ?
Hope you can fix it with not tto much effort.

RE: CMP BF109F BUILDING THREAD
 

DANG![:@][:@][:@][:@][:@][:@]

RE: CMP BF109F BUILDING THREAD
 

I`ll try and get some photos up soon. Been busy with a P-51. The more I look at the BF-109 the more I like it. It has a few issues like the trailing edge thickness. The size of the underwing radiators are a bit small. I plan on getting a detailed cockpit from dbalsa and modifying this plane quite a bit but overall I`d say it`s a good start. Not sure about what retracts to use. The way CMP has it set up the gears would not be at the correct angle so for those wanting the right look it will take some work. As for the engine I plan on useing a RCV but it seems like the front of the plane is big enough for just about any engine to fit inside. The spinner is huge. It`s like half a soft ball!

RE: CMP BF109F BUILDING THREAD
 

a year of waiting and then that! DANG...

I sorry for you man

But as I know you it WILL be ready for the WBOR


Happy landings

RE: CMP BF109F BUILDING THREAD
 

The damage is bad enough that it also has internal damage on the wood support along the inside of the fuse. There are a total of 5 cracks on this side of the plane and the wing saddle one is the worst. There was no external box damage so probably damaged when packed into the box
Can I fix it? Well, depends on your level of visual acceptance. Sure i could patch it from the inside, but the cracks themselves would still be visible on the outside, especially with some of the paint chipped off.

I have contacted Nitroplanes about it and they requested pictures. So I took some and emailed them to the email address they provided on the phone. I also posted on the nitroplanes support forums under the ARF or RTF sub forum. I have not gotten a response back yet.
I am debating on whether to buy another plane all together from the other distributor ( Ak-models) just so I can get the plane ready for WOTR in late Sept. The manual makes it look like it should be a somewhat easy build, just kinda complex in a few areas(the split oil coolers flap/spoileron). If I did this, I could make the damaged fuse into a glow plane and basically repaint it into another scheme and just simply not detail it as much. I like this idea some, but not too kean on having to purchase another $299 plane just to get ONE ready for warbirds over the rockies. I dunno how fast nitroplanes will(if) service this issue.
I dont exactly have a glow motor lying around to use either. That would entail yet another expense unless I used the saito 125 from the german spitfire I have. This plane also needs to be at WOTR...so if I did that, Id have to get another motor for it or convert the Spit to electric. I have a speed control I can use if I did this, and would only need like a Power 90 or 110 to accomplish this. However, thats half the cost of a glow motor already so again Id have to order a motor from hobbycity to make this work as well(about 2 weeks to get it and would cost about $80 with shipping).
Not sure what to do at the moment.

RE: CMP BF109F BUILDING THREAD
 

Man, That stinkc...I sure hope they take care of you on that.
i've already requested to order another spinner for this, but my plane hasn't arrived yet so i hope they answer e-mails at nitroplanes.
can you please post more pics of the rest of the plane while you have your camera oput ?
Thanks!

:D

RE: CMP BF109F BUILDING THREAD
 

I have had some luck in my dealings with Nitroplanes, and hope you do too. Bottom line, the damage is just not acceptable! Keep us informed on how they treat you. I am VERY satisfied with my recent dealings with A-K Models.

RE: CMP BF109F BUILDING THREAD
 

I got mine in today, as scheduled. The box was a little munched at one end, but I got lucky and there didn't seem to be any damage anywhere. Also, all parts seem to be present, but I haven't done a thorough inventory yet.

I hope you have luck with getting the parts you need. I have CMP's 140-sized P-51, also purchased from Nitroplanes, and it came with the wrong flaps....after a quick phone call and an email follow-up I had the replacement flaps in about four days with no further problems. Good luck.

The exhaust stacks are cool, but I wish the wing was fully sheeted.

Tim

RE: CMP BF109F BUILDING THREAD
 

Holy Smack!!!
I'm sooo excited ~:D
I can't wait for mine to arrive!!!!!

RE: CMP BF109F BUILDING THREAD
 

Well...I figured 24 hours was enough for them to respond and they didnt. So, I called them back up.....they didnt answer the first time I tried today....but they may have simply been away from the phone.
Anyhow...spoke with someone and they checked to see if they had received the photos I had emailed. I was put on hold and then he reported back they did and had looked at them.
After being put on hold twice again, the guy did say they would send out a replacement fuse. Good. Now....lets hope it doesnt take them forever to get around to it. This is a problem when a company develops a less then good customer service rap, no one expects they'll jump right on it and fix the problem right away. Now, hopefully they will, and if they do, I will happily make note of that. If they dont, well, it wont help their image any, thats for sure.
I dont like being negative about a company I've done minimal business with. I have ordered small stuff before(like a couple 1/6th pilots) and did receive them, but it seemed like it took 3 weeks.

Now....we'll see what happens, but since they didnt ask me to return the box I can at least get started on the wings and get them finished. Hell, I might install some wing tip lights since I'll probably be waiting at least a week to 2 weeks for the replacement fuse to arrive(and thats if I dont have to REMIND THEM). <Man sux to have a perceived poor reputation for customer service doesnt it? Ppl kinda just hammer "you".

RE: CMP BF109F BUILDING THREAD
 

Hey mate,

i believe the me-109 never had a retractable tail wheel....

thanks

dave

RE: CMP BF109F BUILDING THREAD
 

Hey Dave,

I thought I had the same problem you had with a missing rudder, but I found it in the cardboard insert that was over the tail. Maybe yours was taped in there like mine was.

I too am looking up tailwheel configurations trying to figure out how the tailwheel will work (the F's had a partially retracting tailwheel). Hurry up and finish that F-16 already and start the 109 so the rest of us can just copy what you do and buy your mod parts.

Tim

RE: CMP BF109F BUILDING THREAD
 

Want to watch this one

RE: CMP BF109F BUILDING THREAD
 

I have to give props to Nitroplanes. I just checked my email and there is already a msg from UPS stating that Nitroplanes has given them a package and provided me with a tracking number. Delivery is scheduled for the 15th. I just spoke with Nitroplanes earlier today obviously, and at about 4pm MST. Now I have to call that good customer service.

RE: CMP BF109F BUILDING THREAD
 

G'day All,
I seem to be in the same boat as several others....My 109 arrived several weeks ago..but too many projects on the go already and I want to dedicate some serious time to this bird when I start!!! The worst thing is I have a Saito FG36 gasser sittin here waitin ta go in!! Man I want to hear this thing run:) Can someone confirm which retracts will fit this plane? (don't feel like spending just as much on the retracts...then have to do some major surgery to get em ta fit[:o])

Cheers, Paul.

RE: CMP BF109F BUILDING THREAD
 

Well I just got the notification from UPS, the package should arrive on the 18, cant wait. i hope I'm lucky, and there is no damage on mine, will let you guys know.

Yogi,

RE: CMP BF109F BUILDING THREAD
 

I searched the net yesterday and found two retracts that might be exceptable.The first was robarts 701, 85 degrees, 18 Lb capacity, the second was spring air 551,74 degrees,15Lb capacity. Spring air also has a set with that includes a retractable tail wheel. I'm not sure, but the 74 degree pair might be more scale. Does anyone know what the approximate retract angle is?

RE: CMP BF109F BUILDING THREAD
 

To the best of my knowledge, the 109 tail wheel retract raised vertically via it's shaft only a little bit, but didn't rotate up, nor was there an enclosed area (clear of the fuse slipstream) that the wheel was ever even partly concealed in. like the fw190. By having the wheel slightly raise, it eliminated a small degree of drag, but very little.

RE: CMP BF109F BUILDING THREAD
 

RE: CMP BF109F BUILDING THREAD
 

My computer crashed and I lost my thread in Flickr to thousands of pictures of the bf109 and all its variants. It had the words honor, glory in the title and had 1 group of pics called details of the bf109e. Any clue as to the name of the thread?

RE: CMP BF109F BUILDING THREAD
 

So far I've heard 1.60 Nitro, FG36 & G38 engines may be installed in this bird. Anyone else out there have big plans to put a gasser in one of these?
This plane is probably similar in size to the nitroplanes Texan (I think) i'll have to look and see what people are flying that plane with.

RE: CMP BF109F BUILDING THREAD
 

CMP At6 is 81" span. The 109 is the same span as the 71+-" span zero or p-51d.


The tail wheel on the 109s did retract, however many went with just locking them in the extended position.

Steve

RE: CMP BF109F BUILDING THREAD
 

Scalecraft,
Thanks for the correction, so that means that a G26 should do the trick on a plane that size?
It's just that they list the 109 as a 140 size plane, and the 70" Zero is a 120 sized plane.

RE: CMP BF109F BUILDING THREAD
 

Thanks for clearing up the question if the tailwheel retracted or not. I have seen several pictures of the BF109f with the tailwheel extended. That makes one less problem to deal with.
Has anyone done any sketching as to how the scale gear and wheel could be worked in. The mains are about 4 3/4" in diameter,
while the tailwheel is about 2 1/2 ". The gear is attached to the fuselage instead of the wing and because of the main wheel diameter
slants back quite a bit. The rails installed in the wing are not canted positive enough to position the wheel forward in front of the wing.
I plan to build a mockup of the gear area to get the mechanics working right. Anyone started a layout of the cockpit changes?
www.flickr.com/photos/farinihouseoflove/sets, has a wealth of photos to get ideas from.

RE: CMP BF109F BUILDING THREAD
 

Kinda, the tailwheels on all the Bf109's up to the F were fixed. The tailwheels on the Bf 109F were semi-retractable (the same retract system was used up to the G4 which got a redesign involving a much larger tire and wheel which lead to the tailwheel being locked down). The late model G's and early K's were semi retractable as well. Only the late K's had fully retractable tail wheels...

RE: CMP BF109F BUILDING THREAD
 

I just picked one up from nitroplanes and it looks to be most like the G2-G4 versions due to the two small side scoops added to the cowl sides forward sections.

This opens up the option of using the smaller mains with the spoke hubs or the larger mains with the flat looking hubs used on early Gs

Also, I have noticed in my many books that the latter part of the war resulted in a many modifications and attachments that would give much flexibility in what one can get away with on this airframe.

Is it me, or does the spinner shape look a bit "off". Maybe if I put the cannon detail on the spinner??

Steve

RE: CMP BF109F BUILDING THREAD
 

Hello there,

According the specs, engine size starts with 1.2 2-stroke. I happen to have a 120 AX OS. Is this a good idea, or will it be way underpowered. It turns a APC 14x10 or 15x6 according to OS specs, and delivers 3.1 HP at 9000 rpm. I just want to fly scale like (but the sound, I know). But if it's way underpowered I'll wait untill I've saved enough to buy me a bigger engine.

Thanks,

Eric Schumacher, Netherlands.

RE: CMP BF109F BUILDING THREAD
 

Seems a bit odd to be listed as having 3.1 HP and only being able to spin a 14x10 at 9000rpm's. A saito 100 4 stroke at only 1.8 HP can spin that same prop at 9000.
The specs seem more like a 4stroke since the motor's practical rpm's maxes out at 9500 when most 2 strokes run up to 14000-16000.
Of course, its not a 4stroke so Im a little confused as to why a 2 stroke 120 would not be performing any better then a 120 4stroke. OS's FS-120S III 4 stroke can spin even larger props and its only 2.1HP.
Not sure what Im missing here, but it doesnt seem right.

RE: CMP BF109F BUILDING THREAD
 

9000 RPM with a 15X6 propeller produces 12.3 pounds thrust.

The HP is 1.582

If your engine can spin a 18X6 with 9000RPM then you have 3.280 HP (I doubt it)

This engine will fly that airframe - but just fly...;) forget nice loops.

Happy landings
G-Pete

RE: CMP BF109F BUILDING THREAD
 

Just for the sake of info,, the Dave platt Bf 109G6 with a 78+- span flew very well on an OS 108 @ around 18 to 22 lbs.
