  • Nice mod. Do you see any REAL improvement on the motor's life?

  • hello.

    The temperature drop down around 5 degrees ( Celsius ) with the cooler. But I did not do further research to measure the new life time of the engine compared with an engine without the cooler.

  • amigo; gostaria de ter seu e-mail para trocar algumas informação ref este heli, só que o meu é 4#3 A , e percebi que os servos nao sao tao precisos, causando algumas instabilidades, motivo pelo qual ainda nao me arisquei decolar.

  • Seu receptor é diferente, e não possui ajuste de sensibilidade nos servos, de modo que não sei como corrigir este problema especificamente. Abraço.

  • Another idea for the main motor heatsink, I took the heatsink from the tail of my blade cp and it fit the main motor perfectly.. This works pretty well...

  • Good idea ! Thank's for sharing. :)

  • Onde vc comprou esse heli no Brasil? Moro no canada e nao acho por aqui. No ebay todos vem da China...

  • Moro na China. Comprei aqui.

  • Hi man, all your vids are nice. I got a problem with mine 4#3b. I change the main motor an battery but the heli don't want to fly, some tip? thank

  • Well. It's hard to say. But you must try this:

    -the main engine conection in the receiver is in the main. Mot. position.

    -The engine you put, is the 4#3B engine,(with a hole on top). Note: if you put another similar engine used in other kind of small helicopters, it may not produce enough speed.

    -The main propeller must be original for 4#3B.

    _Take the engine out, and check if main rotor is running free.

    _Check with another batery, fully charged. I hope it can help you. :)

  • very good idea. i will use it on my heli too. other people said that you could wrap the motor with soldering wire, but i think yours is much better and lighter. also, what is that glue that you were talking about? can that be found in any hardware store? once again, good work. i look forward to seeing more from you. thanks

  • The soldering wire also works and it's easier to do, but has much more weight and also gives less area for cooling. It's not a glue, it's a kind of paste to conduct heat. I didn't use in my motor, and the heat sink works good,but some friends told me it get's better with the paste. I think you can find it in some electronics repair store or maybe, as you said, in a hardware store. Just ask that is a kind of paste they put between metal parts to conduct heat between each other. Thank's.

  • O radiador da cauda reduzi pela metade o tamanho, pois estava influenciando no fluxo de ar da helice. I reduced 1/2 de heat exchanger in the tail, due to air flow influence in the rear propeller.
