Unii dintre voi poate au urmarit acum ceva timp constructia modelului F3A Radiance aici pe RHC. Din pacate pozele de atunci s-au pierdut, fiind gazduite pe un server care nu mai este disponibil.

Dupa finalizarea constructiei si zborul primului prototip, am inceput sa ma gandesc la versiune imbunatatita, care sa o pot oferi sub forma de kit de asamblat. Folosind experienta acumulata in cursul constructiei primului prototip, am adus cateva modificari formei exterioare a modelului si am reproiectat integral structura interna pentru a reduce greutatea. De asemenea am decis sa proiectez o aripa noua in sageata pentru mai multa stabilitate, cu structura de balsa si ale carei piese sa incapa intr-o cutie de dimensiuni reduse.

Tot in aceasta perioada, am hotarat sa imi unesc fortele cu o mica firma din Africa de Sud, specializata in prelucrare cu comanda numerica , taiere cu laser si realizare de prototipuri si care se va ocupa de fabricarea kit-urilor.

Inca 2 prototipuri au fost construite si testate in zbor in Africa de Sud. Ultimul (V3) a fost acoperit integral cu folie Oracover si are o greutate totala de 4850g. Versiunea finala pe care o oferim sub forma de kit este bazata pe acesta, insa are o serie de mici imbunatatiri cum ar fi repozitionarea usoara a aripii si eleroane marite pentru un snap roll mai rapid la viteze mici.

Mai multe informatii puteti gasi pe http://www.radiance-f3a.com
Pretul oficial il puteti gasi acolo. In caz ca este cineva interesat, contactati-ma si pot obtine un discount de la producator.

In final, cateva poze cu structura modelului. Voi adauga de asemena in zilele urmatoare si poze din timpul constructiei.

O realizare deosebita .Felicitari !!!

[REAL DESIGN]

Super profi - gandire, proiectare .. tot ! Jos palaria ....
Era bine daca putea fi achizitionat in 2 variante :
- KIT ( cine stie si are si timp )
si
- ARF ( cine e dornic sa iasa la camp mai repede desi si un ARF daca vrei sa il faci ingrijit nu il termini doar
intr-o zi).

Despre nivelul de pret al kit-ului ..... ??? .... avand in vedere ca mai trebuiesc multe de luat sau de facut ( tren carbon, tevi carbon, lonjeroane, roti, si toate maruntisurile - balamale, echii , surubaraie, cabluri, balsa si folii divers colorate pentru infoliere, adezivi ... )va fi grea alegerea avand in vedere sa spunem doar modelul celor de la Extreme Flight ( http://www.extremefl...2MVanquish.html )si mai sunt si niste chinezi cu un model foarte raspandit la ei si nunumai F3A Neptuno 170 ( http://www.jetlegend...dex.php?Page=18).

Multumesc pentru aprecieri.

ARF din pacate nu il putem oferi, compania care fabrica kit-urile este f. mica iar constructia dureaza destul de mult.

In ceea ce priveste costul, trebuie avut in vedere ca acest kit va fi fabricat in serie foarte mica si prin urmare nu poate rivaliza ca pret cu modelele ARF produse in China in cantitati industriale (sute sau mii de bucati). Cunoscand lista de cheltuieli a producatorului, te asigur ca profitul este minim si abia justifica efortul pe care il presupune fabricarea. Ca un termen de comparatie, atunci cand am construit modelul meu m-a costat 200$ numai taierea laser, fara materiale.

Pentru o comparatie mai potrivita, sa luam alte 2 kit-uri de asamblat pentru modele F3A:
Harmony 2 1450$
Wingray 1500$
Nici unul nu include tren de aterizare, de tub carbon nu au nevoie fiind constructii cu aripa dintr-o singura bucata.

Exista intr-adevar si kit-uri mai ieftine cu aprox. 100$, dar pentru aripi sunt incluse doar miezurile de spuma care sunt foarte ieftin de produs in schimb ocupa mult loc si ambalajul de dimensiuni mari presupune costuri mari de transport.

Neptuno 170 este un model ARF de compozit care costa mai mult de 2000$ cu tot cu transport, asa ca nu prea se poate face comparatie.
Vanquish intr-adevar e un model ARF bun si ieftin (650$ in US). In Europa il poti gasi la Lindinger insa mult mai scump (echivalentul a 990$), iar cu transport sare cu mult de 1000$.

Iata si cateva poze cu continutul kit-ului:

Nu vreau sa poluez topicul dar ar fi pacat sa nu te felicit. Am vazut ca ai starnit interes pe forumurile de afara. Sigur nu o sa te imbogatesti dar e placut sa vezi ca munca ta e apreciata.

Bunuiesc ca succesul kitului depinde de cum zboara modelul.

[Mihai_supy]

De ce oare lucrurile frumoase sunt de regula scumpe????

[Bloodhound]

Multumesc Stiganas. De imbogatit nu poate fi vorba, dar daca clientii vor fi multumiti de calitatea kit-ului, poate fi o rampa de lansare pentru alte modele in viitor.

Iata si cateva poze cu primii pasi ai asamblarii fuselajului. Din pacate avem o restrictie de 500k pentru attachment-uri ceea ce ar insemna sa postez pozele una cate una, asa ca a trebuit sa pun pozele pe un site extern.

Nu exista planuri de aranjare a pieselor ?

[Bloodhound]

REAL DESIGN, la 22 March 2012 - 07:18 AM, a spus:

Nu exista planuri de aranjare a pieselor ?

Kitul cuprinde instructiunile de asamblare in format PDF pe CD, desene printate la scara 1:1 pentru pozitionarea nervurilor aripii si ampenajelor, desene de ansamblu si desene ce permit identificarea pieselor componente dupa codul de litere asociat fiecarei piese. Toate planurile printate sunt de asemenea incluse si pe CD.

Cateva poze din manualul de instructiuni se pot vedea aici: http://www.radiance-...ions-manual.php

In plus, toate piesele prezinta decupaje pentru asamblarea cu piesele vecine, astfel incat nu prea ai cum sa le lipesti gresit.

Pentru conul elicei, am ales sa folosim o matrita realizata pe un strung CNC, impreuna cu o scula pentru presare al carei rol este sa asigure o buna echilibrare a piesei finale. Dupa intarirea rasinii, excesul de material este de asemenea taiat pe strung.
