Hi,


Just a small thread which could have spare me a bad first order for my kids.

My 8 years-old son wanted a real RC car, not the analog toy kind you get in kids stores. So I bought him the Turnigy Stadium 1/18




But unfortunately this car proved to be very fragile:

- ESC DOA
- Brushless Motor broken after 3 runs
- Very bad diffs which would strip each 3 runs and cost 9$ each.
- steering link breaks at each frontal crash...

Anyway I spent more then 120$ on it and my kid is now afraid to push it.

Then I bought a more cheapy 1/18 model for my 5 years old boy, the WLTOYS A969 on banggood.

Results : GREAT! Same power as the stadium truck and a hell more solid (Remember, my 2nd one is only 5 years old)

Stadium vs A969



So I will buy another one as a replacement for the stadium.

Here the models based on the same structure (each body has 2 color schemes)

wltoys A949/A959/A969/A979


Positiv :

- Tx/ESC/Rx not really swappable on other models
- Brushed Motor, but very big/tough in comparison with the stadium one
- Battery tray is a little short (1400Mah max)


positive :

- Price (69$ RTR 2.4Ghz with charger + battery)
- Powerful (I had to reduce the power for my kid)
- Tough
- Compatible with some classic RC parts (wheels with hex nuts etc....)
- Parts available
- 15-20mn play pro lipo
- 4 AA batteries(not 8) in the TX
- Precise steering (no play like the stadium)

Salut,

Juste un petit thread qui m’aurait permis d’éviter un mauvais choix initial (je vais pas vous faire une review complete).

Alors voila, mon fils de 8 ans voulait une vraie voiture RC (il bavait devant ma Turnigy Desert Buggy 1/8).
Dans les magasins maxitoys etc.. il n’y a que des mauvais jouets en analogique sans puissance donc je me suis décidé à lui acheter la Turnigy Stadium Truck 1/18.




Mais par malheur celle-ci s’est avérée treeeees fragile, liste des pannes :

- ESC mort a la livraison
- Moteur BL Mort apres 3 runs (depuis remplacement OK)
- Les différentiels qui se petent apres 2-3 usages (9$ piece !) et pas d’alternative.
- Piece avant (steering link) qui pete apres chaque choc frontal

Bref j’ai deja dépensé une fortune (+ de 120$) et le gamin n’ose plus pousser les gazs.

Puis j’ai acheté un autre modele 1/18 plus "cheap" sur banggood pour mon fils de 5 ans, le WLTOYS A969.
Résultat : Une révélation ! Autant de pèche que la stadium truck et une sacré solidité (je rappelle que c’est mon fils de 5 ans qui pilote )

Comparaison stadium et A969




Du coup je vais réparer une derniere fois la stadium, la revendre et j’achete de suite un autre modele WLtoys (Mon fils de 8 ans a choisi la A959 en bleu)

Donc voici les modeles qui sont bien (2 couleurs possibles a chaque fois) (wltoys A949/A959/A969/A979): Attention ne pas prendre les modeles LXXX
Elles sont toutes sur le même chassis...Continue Reading

Hi folks,


I recently bought a Gopro 3 and wanted a light-weight Case with a cheap replaceable lens protection.

As I did not find it on the market I asked my friend which has a cnc: Why don’t we produce it ourselves?

Some thinking, sketches and tests after that the GP3-Box was born.




gp3box (1 min 28 sec)




Here the main specs:

- Light

- affordable

- should protect the whole Gopro and not only the lens

- Lens protection is easy and cheap to replace



The lens protection is a UV filter, it is simply screwed like on a DSLR. The screw is compatible with all matching photography accessories. So If you break or scratch the UV filter you can replace it easily. You can also change to a polarisation filter or whatever you want to make some shots with special effects.

For transportation you can also buy a cheap1$ 37mm snap-on to protect even more your gopro (must be bought your side).
