About this Plan

Broussard MH-1521. Radio control scale model. Wingspan 220 cm, for 10 - 15 cc engine and 4 or 5 channels.

Quote (translated from the French): "THE SPECIAL OF THE MONTH: Two 'Broussards' this month - one is an original creation (1.96 m for 7.5 to 10 cc), the other is the ex-Baby Train plan (2.20 m for 10 to 15 cc). I thought it would be better to present them to you together, with nice documentation, so that you can more easily choose. Good flights for 1991, Pierre Rousselot.

Broussard MH-1521, by Roger Nieto.

You want a do-it-all plane, large enough, with very realistic flight qualities , you also want it to be a semi-model, don't hesitate, build the Broussard. Okay, there's some work, but it's worth it. Take a look at this beast, nice isn't it?

Construction: After careful examination of the plan, I made some modifications by adding a cargo hold, functional doors, and shutters. Thus we fill the hold through the doors, and the flaps provide spectacular flight qualities.

To undertake construction you should be able to count 3 or 4 models behind you. I will therefore only cite the key points.

Fuselage: Before assembling it, in two half-shells, do as I did, provide an air vein for cooling the engine, there is no shortage of space. As for the wing key system, I opted for the 2 mm dural imprisoned in the 3 mm CTP provided on pairs 4 and 5. Also provide a hatch to access the train in very flexible AG 5 which has to absorb possible shocks. If you let yourself be changed to the optional, mantel the vault and the doors.

The major concern when looking at the plan is the hood, 'damn' what a piece! Rest assured, this is easier than it seems. The assembly in two parts poses no problem; To make the rounding, make a 100/10 balsa template to which you stick an abrasive. For the deflectors, use rhoclaki. Make two fixing platforms from the inside on couple no. 2, and the result is superb.

Wings: For the wings, nothing special ; the flat profile facilitates construction, however I recommend making jacks with a slot effect. In this case, the offset hinges are 2 mm thick, and the transmissions are vela cables, a simple and effective solution.

Empennages: For the tailplanes, it will be necessary to enlarge the fin jacks which do not conform to the real ones, moreover their efficiency will be improved. In addition to transport, the removable empennage is very useful for saving access to the roulette and depth mechanics.

Engine and radio installation: All we have to do now is install the hardware before finishing. For the radio there is no shortage of space, the only difficulty lies in the transmissions, jacks, ailerons . I chose the vela cable solution which avoids extensions, numerous servers , and access hatches, installation is easy with radius option plus plastic screed.

For the engine I put one back into service 0.5. 90 FSR equipped with a pot that Pepe Bointon, our president, made for me in an oil can. The sound result is great.

As for the finish, I covered the hood with two polyester resin women's stockings, all putty and sanded, lightness and hardness guaranteed. The fuselage was covered with sole and the wing with Solartex. The aluminum, airbrushed, comes from Graupner paints; be careful, this color is not very forgiving, the surface condition must be taken care of, but the effect obtained is not 'bug-bitten'.

Flying: I admit that for the first flight, the details of the problem seemed very simple to me. Judge for yourself: 15 cm2, 5.2 kg, 86 g per dm2, easy peasy.

Finally! I still had shortness of breath and a tight throat. At present, the plane has made around thirty flights. For takeoff set the flaps to approx 12° and push the throttle gradually; as soon as the speed is sufficient, the bird flies away on its own. We took off without any problem at two-thirds throttle. Once in his element, the Broussard is very stable and the realism is striking.

The appeal of this type of aircraft lies in the precision of the controls and reactions. A treat for fans of slow planes. The zinc doesn't really detach, it sinks gently onto the nose, plus it's useless to control three axes. In terms of power, the 90 FSR is comfortable, however glider towing remains to be tested.

Finally the reward is the landing, a real spectacle, with flaps at 15°, 20°; the plane is slightly pitched up, the engine is at a third of the throttle, it is very maneuverable and you can skim the runway without being the 'ace of aces'. However, the large fuselage is completely crabbed when the wind blows from the side, it is then preferable to do without flaps and land instead with more speed.

I used the following deflections: ± 15 mm at the elevator, ± 18 mm at the ailerons; some differential would be useful, say 25 mm upwards, 15 mm downwards.

Conclusion: After this short presentation, if I have piqued your curiosity without convincing you, I will wait for you on the Ailes Rabelaisiennes grounds for further information. If your crush is already there, get out the cutters, and good luck."

Quote: "Hello Mary, and Steve too. Here is another contribution from the Netherlands. In the December 1990 issue of Modèle Réduite d'Avion (MRA) not one but two plans were published of the same airplane. I ordered the one and ...received the other.
Link to the original French article: https://mach34.fr/construction/Artic...
An English translation is attached.
Wingspan is 87 in. The early version of this plane had a short nose. Later version had the nose lengthened and the engine moved forward by 100mm. The author states he used the early version for his model. With a scale of 1:6.25 adding 16mm to the cowl makes it a later version.
The plan I ordered was the later version. Later version looks better. 100mm makes a difference. The plan shows some creases but nothing critical and as the scan was a free service I didn't dare to complain. I cleaned up the plan but perfect it is not.
Sorry for all the work I caused. And there is also a part 2 in the making; The one I didn't get."

    ScaleType: This (oz15038) 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.


    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Max_Holste_Broussard
    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.

Hello Mary, and Steve too, Thank you for the publication; it looks great!
To support my statement that the Max Holste looks way better with the extended nose (and to brag, of course), I attach a 3Dview that I drew in Inkscape. It has the same scale(1:6.25). Underlying construction was unfinished and therefore removed. Maybe one day. Meanwhile, interested modellers can do their own construction. Greetings from The Netherlands,

Notes

* 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.

Scaling

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.
