Focke-Wulf Ta 154-A1 Moskito (oz5926)
About this Plan
Focke-Wulf Ta-154-A1 Moskito. Radio control scale twin for 2x .40 engines. RCM plan # 642.
Quote: -"The Rare Ta 154 Moskito Night Fighter is an Excellent Scale Twin Engine RC Aircraft for two .40's. By Franz Meier.
Twin engine scale model has been on my building agenda for a long time. I was looking at various types such as the Grumman Tigercat, the Martin Marauder, and the Me-262. I had already finished a plan of the Tigercat when I saw an article about the FW Ta 154. Full of enthusiasm about this plane, I hung the Tigercat to the famous nail on the wall and began the design and subsequent construction of a scale version of the FW Ta 154. The simple and clean lines of this plane fascinated me and everything seemed perfectly set up for an R/C scale model.
According to the new rules for scale R/C aircraft, this design would have to be classified as semi-scale. However, this fact should not dampen your enthusiasm for this. The sound of two engines at high rpm's can even be felt in your fingertips much like a trumpet solo by Louis Armstrong. And you will find, upon completing your model and making the first test flights, that scale regulations just aren't important any more as you make a high speed pass two feet off the deck with your Ta-154, or gaining velocity to execute a perfect loop.
Built-up mainly from balsa, plywood and hardwood, the construction materials are almost identical to what was used on the full size aircraft. Two main balsa longitudinal sides are reinforced with plywood where
necessary and are the basis of the fuselage structure. The formers are glued in segments to this basic structure. This is then covered with 1/8 balsa sheet to obtain a light, but rigid, and torsionally stiff fuselage.
I exercised a lot of care in the design and construction of the wing. The airfoil at the wing root is an NACA 2417. The wing section remains identical out to the engine location and tapers from there by about 3%. The angle of attack of the center section is two degrees which is reduced to 0 degrees at the wing tips. The tolerances on the wing have to be kept to a minimum since they all have an influence on the performance, especaily due to variations in the engine thrust angles!
From my early experiences with the Orion (oz927) designed years ago by Ed Kazakirski, I remembered the problems I encountered building a perfect wing with the landing gear mounts. Therefore, I looked for a Way to mount the engine mounts only after completing the wing. This can he done by cutting the wing sheeting in the area of the motor mounts and to bolt and glue the formers each to the lower portion of the wing spar. These formers are the basis for the engine mounts and the cowls which cover the cut-out in the wing sheeting when cornplated. This design provides a rigid attachment of the engines to the wing, which is of absolute importance due to the relatively long motor mounts. We also have to consider that this construction is not only the basis for holding the engines, but also for the landing gear and the throttle servo as well as the cowl.
I was studying the installation of a retractable landing gear, however, I decided to use a rigid, but scale, version of the original gear. The main reason for this decision was the fact that I was not satisfied with the reliability of the available retractable gears for heavy scale models. The experience with the unique scale landing gear, even on rough ground, proved to be exceptionally good.
For the engine exhaust, an ideal solution could easily be found simply by modifying the mufflers and installing a flexible rubber hose so that the exhaust gas can be fed directly into the flame tube on the muffler side. The aesthetics of the model are not disturbed by this modification and there is a high degree of protection for the. model against exhaust residue. The accessability of the mufflers and tanks is good due to a bolted-on cover..."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

ScaleType: This (oz5926) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.
If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.
ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Focke-Wulf_Ta_154
Wikipedia page addresses may well change over time.
For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

User commentsHi Steve, Mr Meier is from Switzerland. His first name is not Frank but Franz. The German Mosquito plan is one of his Best... Great for electric power conversion... Regards,

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
