RE: CMP BF109F BUILDING THREAD
Assuming about 8500 rpms, youd see 80mph STATIC. So...maybe a tad more if the motor unloads a bit in flight, but that static number does not include drag of the airframe or prop efficiency. Best guess.....70-75mph

awesome, thats the speed I was hoping for. thanks!

Hey Guys, Hope everything is going well. I have been getting a lot of request lately for the spinner I use to carry for the CMP Me 109. Unfortunately I no longer carry the spinner due to problems with the supplier. So i just want to point ya'll in the direction of the two spinners that are available.
Dave Platt has a spinner that will work that is just a tad small. I do not have the price for that spinner Dave Platt Models Inc. 1306 Havre N.W., Palm Bay, Florida (321) 724 - 2144 http://www.daveplattmodels.com/ Fliteskin It is just a tad large 148MM and front of CMP 109 145mm $95 Jose Gutierrez 2371 Evergreen Court Pembroke Pines, FL 33026 USA http://www.fliteskin.com/ Here are pic's of both on the CMP 109. I pulled these pic's offline. Platt is beige and the Fliteskin is all aluminum. |
RE: CMP BF109F BUILDING THREAD
The dave platt spinner is $55. The backplate is aluminum and the dome is nylon/fiberglass mix or something. You can by the dome alone for $30, but its pretty stout. Its also a bolt thru the nose style so you can simulate the nose cannon.
The one from flightskin is ok too, but not bolt thru nose so no scale cannnon. Myself..Im not really a fan of tapping a spinner done to put a bunch of screws around the perimeter, but thats me. There's nothing wrong with that, I just dont have the tools to line things up right. Whichever you chose Experten, you'll make it look awesome Im sure. |
RE: CMP BF109F BUILDING THREAD
without a doubt I'll go with the Dave Platt spinner. :D I'll probably buy 2.

Hi, Friend my name is Jaime Reyes and I received one CMP Messerschmitt Bf 109F (HAHN) 120 - 73" Nitro Gas Radio Remote Control Airplane (Warbird) as gift in Christmas but until now don't open the box and every thing is Ok except I don't have manual. I call Nitroplanes but they don't have too, if you can there are any way that can I find one copy of this manual, and let me know your experience whit yours.
Thanks in advance. Jaime reyes |
RE: CMP BF109F BUILDING THREAD
I believe you can get an on-line copy of the manual at this site. You have to register to access.

Once you get the manual printed, you could burn it to keep you warm. You'll learn a lot more by reading the posts on this forum.

RE: CMP BF109F BUILDING THREAD
I need to now how the air brake work because i never has seen something like that before

In my case I set up the linkage for the "brake" to start moving more in the second part of the flap travel. My radio lets me know with a beep that I have hit the mid-point of the control (I use a rotary knob). I don't need full flaps (and full drag) when there is a head wind. Keep in mind I have an OS 1.60 with a 17X10 prop. It needs some drag to help it slow up, and the split flap/brake function gives plenty of drag, likely too much for some engine configurations. The instructions do show how to hook it up, but the length of the horns can determine when they kick in.

RE: CMP BF109F BUILDING THREAD
I never install before an rotary knob, I don't know how this work and how install
Do you have some pics . Thanks for your help Jaime |
RE: CMP BF109F BUILDING THREAD
He means rotary knob on his transmitter...he uses that to control the flap deployment....which...in the case of this plane, the stock setup for the airbrakes are controlled from the same servo as the flaps.
BUT...in my case...I set the airbrakes up on a completely different channel with separate servos from the flaps. They can be switch on or off without any involvement of the flaps. I have found the airbrakes are pretty much useless for me. While they may slow the plane down a bit when landing, I have only used them once. |
RE: CMP BF109F BUILDING THREAD
Thanks for answer , thats is the way I wan to set up my air brake, but I don't know how do to work the uper brake simultaneus whit the down one,
Could you send me some pictures of the system that nove the brake? Thanks. Jaime |
RE: CMP BF109F BUILDING THREAD
Ok guys ya'll are killing me with the term airbrake...It was a "spoiler". it was used to allow more air through and to kill the lift caused by opening up the rear of the radiator. Ok this is a model and we can use it as an airbrake... You can watch this video of a full scale one. It was open on takeoff for cooling and down for landing when full flap needed..
http://www.youtube.com/watch?v=dO9mEv5Ve54 Now back to out regularly scheduled thread........ |
RE: CMP BF109F BUILDING THREAD
Yup I know what their really called Fockewulf, but had I just said spoiler, Jaimereyes may not have understood what I was referring to.
Anyway...aside from allowing more air to escape the radiator coolers, they did act as spoliers, however, were generally temperature controlled and not usually pilot operated. I do believe there was a manual control for them, but dont remember. |

We seem to have the spoilers / brakes discussion every time we mention them. Since we use them exclusively to create some additional drag, we often call them brakes or airbrakes in this thread to reduce confusion. Since I have a high pitch prop, I use them quite often. If I did not, I would most likely lock them level with the wing surface. They are not too realistic as I use them, most would agree that the spoilers did not move above the wing surface in flight modes and would go down with the flaps in most cases depending on the engine temp.

RE: CMP BF109F BUILDING THREAD
Yes, the inner radiator flaps modulate depending on flap position and engine temp. I think the idea was to maintain the wing lift at some set amount no matter how far open/closed the two flaps were, hence you will often see the upper part somewhat above the trailing edge. The upper flap is also double skinned, the gap between the two skins providing a constant air bleed around the radiator and maintining cooling flow through the radiator independant of attitude or flap position. It was quite a tricky set-up, but only from the F model onwards, B to E was quite a bit simpler.

RE: CMP BF109F BUILDING THREAD
Thats close Pimmnz, the radiator flap moved progressively to maintain the cooling airflow to the radiator. Not for lift though.

RE: CMP BF109F BUILDING THREAD
Ahh, knew it was one or both...

RE: CMP BF109F BUILDING THREAD
Guys,
I'm planning to use the supplied fuel tank that came with the plane (CMP bf-109) with a OS 1.60 nitro two stroke. I noticed that the stopper for the tank is a reddish brown color. Does anyone know if this stopper can be used for nitro fuel? Looks like a gas fuel stopper. Also, does anyone have any other fuel tank recommendations for this plane., Thanks, Messer |
RE: CMP BF109F BUILDING THREAD
I'm using the supplied stopper and it's working fine.
