Ciao, sono possessore di un P47 Alfa model distrutto completamente al primo volo a causa del longherone delle ali probabilmente diffettoso! Vorrei sapere ora che l'ho riparato/ricostruito dov'è il centro di gravita (cm dal bordo entrata dell'ala). Grazie. |

Se tra i pezzi che hai potuto avere la fortuna di recuperare ci fosse la parte in plastica sottile che riveste la parte inferiore dell'ala ci dovrebbero essere due bugnette (con la B non con la P ![]()

| Tutti gli Alfa hanno due piccoli rigonfiamenti (poco più grandi di un chicco di riso) sotto entrambe le ali , vicino alla sede che nel vero aereo ospita i carrelli, e sono il riferimento per il centraggio. In alternativa opta per il sistema classico, e come suggerisci, lasciandolo leggermente picchiato...

EDIT: come non detto, non è in PDF ma semplice testo: P47 THUNDERBOLT 0201 ![]() Congratulations on purchasing this scale model, depicting the Republic P-47D Thunderbolt, a WW 2 fighter.The actual aeroplane was created according to the specification issued by the USAAC technical command, using the lessons learned during the first period of the WW 2. The semi-finished XP-44 lightly armed, lightly armoured interceptor project was soon completely rebuilt to the XP-47B. The new machine, powered by the eighteen-cylinder double row Pratt & Whitney R-2800 radial, with a turbo-supercharger, had, despite its weight around 6 tonne, became an excellent, yet heaviest single-engine fighter of the WW 2. Its prototype took to air for the first time on May 6th, 1941. It joined the combat over Europe in spring 1943. It was the first US-built fighter that provided USAAF with a degree of superiority over the enemy fighters. It bore the brunt of the most difficult period of air offensive against Nazi Germany and imperial Japan. Its significant feature was the measure of protection it provided to its pilots. It was apparently the safest fighter of the period. Due to its aerodynamic finesse, weight and sturdiness the P-47 could follow enemy into any dive he could muster, or, vice versa, use its superior diving speed to evade enemy attack. Besides that it provided an extreme measure of protection in dangerous strafing attacks as well as in an eventual crash landing. The P-47 Thunderbolts were series-produced in the B to N versions. The D-25 was its first variant with a full-vision bubble canopy. The M version was the "sprint" T'bolt with max. speed over 700 km/h, the N had a new wing of greater span and more fuel for the distances of the Pacific. Altogether 15 329 of P-47's were built, 12 600 of that number of the D variant. Their pilots flew 546 000 missions, destroying over 7 000 aircraft, 9 000 steam engines and 6 000 vehicles. The most successful P-47 Thunderbolt unit was the 56th Fighter Group of the 8th Air Force, USAAF, that destroyed 1006 aircraft with 128 losses to their own numbers. The Thunderbolts served, besides the USA, in Bolivia, Brazil, Chile, China, Cuba, Dominican Republic, Ecuador, France, Guatemala, Iran, Italy, Mexico, Peru, Turkey, UK and the USSR. Catalogue No.0201 The supplied set of decals enables you to build one of the three versions of markings:
Catalogue No.0209 The decal set enables you to choose from two camouflage and marking schemes of the 405th Fighter Group. The model is not suited for complete beginners, but its control with ailerons and elevator would not bring problems to any modeller experienced enough with elevator/rudder control models, e.g. slow-flyers. The flight qualities and performance of this scale model of the P-47D Thunderbolt are close to that of much larger models, i.e. they are more docile, and provide fine as well as colourful experience in the air. The model kit you have bought has several noteworthy features:
Finishing the model It is a simple task, yet we ask you to read and follow the subsequent text carefully. When opening the cockpit canopy, use the following procedure:
The model is sprayed with colours making up its basic camouflage scheme. The codes and markings are on the waterslide decals. Their primary advantage is the negligible weight and a minimum risk of damaging the model during application. They require, however, an attention and care. Therefore we recommend you to follow the subsequent tips:
The general layout of the electrical connection is on the diagram. We strongly recommend you to assemble and connect the RC equipment outside the model and check its function. Observe the recommendations of manufacturers as listed in the directions for use for the respective components. Check the compatibility of the receiver with the crystal used - the over-the-land range test of the transmitter, albeit it may seem unnecessary nowadays, may save you so much more than it would cost ![]() (motors with MPJet gearbox or MPJet outrunner 28/7 )
The aileron servo should be powerful enough to overcome the friction in the control circuit - we recommend to utilise a servo of more than the 15 Ncm minimum torque. You can minimise the friction in the control cables by removing them from the tubes and lubricating them lightly with thin oil, e.g. the WD-40.
For the elevator control a servo of the minimum 7 Ncm torque is required. Both moving surfaces are interconnected by a glued-in coupler. If one of the elevator halves deflects excessively (outside of the recommended angles), the coupler may become loose and the deflections (especially the maximum ones), may differ substantially. Restore their stiffness by gluing (Epoxy) a "U"-shaped connector made of steel wire of 1,5 mm diameter.
To facilitate the transport and storage, the wing of the model is detachable. The fuselage and wing are joined by the screw 16 - tighten with care. If you wish to fit the pilot into the cockpit, remove the cockpit canopy carefully (it is tack glued), install the glued and painted pilot bust and re-glue it back. The other possibility is to insert and glue the pilot into the cockpit from below, after opening up an appropriate hole in the fuselage decking. Note: If you manage to get some plastic shavings/sawdust under the canopy, rest assured that its removal shall not be possible without removing the canopy itself. Catalogue No.0201 If you have decided to build the M version (colour scheme II and III) glue the fin strake to the fuselage top decking. It is advisable to sand the edges to come into contact with the fuselage from inside of the strake to ensure that the strake would fit to the fuselage and fin without unsightly gap. E) Flying the model Balance the complete assembled model by shifting the position of battery pack along the base plate . The prescribed position of the CG is marked on the fuselage bottom cover surface by transverse lines (fig. E). When balancing the model, support it with your fingers. The well-balanced model stays level or slightly nose-down. Mark the correct position of battery pack on the base plate - it is best done at home; also check the RC equipment - i.e. the sense and magnitude of deflection (throw) of the ailerons and elevator and the function of the controller. First, glide-launch the model over taller grass to cushion its landings and check its reaction to controls. If you can, set the non-linearity on the transmitter to 50 % both for the ailerons and the elevator. The powered flight will differ according to the power unit - the "280" will make the start just a bit more lively than with a slow-flyer, the AC motor will try to jerk the model from your hand- be ready for a pronounced torque from the propeller in slow flight when the controls are less effective. Once trimmed in powered flight, try the marginal regimes - especially the slow flight and stall behaviour of the model. Once you become accustomed to the model, you may return the ailerons to normal zero setting. The model of the P-47D Thunderbolt, compared to other WW II fighter aircraft, has excellent flight properties and would stand a lot of abuse. But it is no slow-flyer/fun-fly machine or an aerobatic special and you have to adjust the piloting to this fact. You could be surprised by the reactions to the excess movement of the elevator, so please try these figures at higher flight altitudes. Once the Thunderbolt passed the test-flying period, you need not to wait for a calm weather. Thanks to the wide band of available speeds and to the very good controllability it will be soon your decision when to go flying outdoors. We wish you many happy landings Alfa Model. Ltd.

Grazie a tutti ragazzi!!! Il mio problema è sorto dopo aver letto proprio quel manuale... e nel non avere sulle mie ali quei riferimenti!!! Il mio P47 si è letteralmente disintegrato: tipo un X-Wing in volo e tipo un cartoccio di carta alla raccolta pezzi!!! |
