Would you share the schematics?

[Kenny Fong]

Sorry. I'm not the author of this item.
I must consult him for sharing...

Cos' it uses MEGA 8, the circuit schematics is not ALL.
The MEGA 8 program is also the key......

What does it do? Why do I want one?

The PCB uses 1 receiver channel in, and transfer the ignition battery set voltage out to the 8-way pins, with sequencial order...
Its usage is mainly for lauching multiple rockets on RC plane, heli, battle ships, tanks etc. only occupying ONE receiver channel.
And it can be used as a multiple way out trigger.......
For a simple example, with the revise version of this circuit containing 3 additional jumpers to control the way out number, it can be used as a light remote control trigger on RC cars, with the jumpers set to 1 way out......

Hi, Kenny

I Think ILUFA ( Philip SUN ) already committed such a device ... Freely downloadable.

Ah. Those are prohibited under the AMA regulations in the USA.

Hi, Andy

Here also ... but ... Even Policemen like that !!!

Andy, don't you guys have estee rockets in the US, as that is in essance what is attached to the Rappy. Or is it because its attached horizontally and fired from another model... but then I've seen video of RC warships launching rockets and that can't be much different ?

Not sure what the law is in the UK whan it comes to attaching rockets to other models, but you can buy normal Estess (sp) rockets from any model shop without needing a licence etc.

Hi, Malc

The Laws all tell the same everywhere : ( ... you're not allowed to launch UNCONTROLLED rockets from flying Platforms. Even Fireworks.

This why they could hurt people on the ground because horizontally launched.

Just launched more than 30 degrees from vertical is problem enough.

Even rocket assist RC planes (like Estes sells) need to be within 30 deg of vertical.

Thx for all the suggestions and law warning from you.
Thx a lot.
I'm not sure if there's the similar law here in CHINA, but ya know the RC law in CHINA is equal to nothing. Few people abide it, and it's nonet of administration at all.
Anyway, when I'm lauching the rocket from my heli, I must mind the arrounding circumstance, people etc. for safety. We got an excellent flight field here. So I think the safety is important but no problem.

In fact, the safety is the most I've thought about and concerned.
