Rx7/rx9 reciever only

Hello Mikado specialist.

Can i use the RX 7/RX 9 in a 27 years old heli?
I dont use Gyros because its a Paddle heli.
I have a singel GY401 for tail and 3 swash servo and a gas servo (Is a Nitro heli)
I have a Vbar control touch

Hello,

if you are familiar with the macrocells and like to programm all the needed stuff like swash mixers, collective curve, throttle handling, flight conditions etc. there on your own - yes. But consider this will not be supported as it makes no sense.

if not - use a VBar.

Thx RV

Hi,

I'd rather use a NEO or an EVO and zero out swash plate gains.
This way, you have the swash plate mixer, tail gyro (if desired) and governor (same) with feed-forwards, and you can even use Rescue.

But mixing Ch1-3 is also not too difficult to achieve, per bank makes it more complex, though.

Thanks Eddi.

But Neo or Evo i can not use because i use Analoge servos,4,8V recever, Mechanical tail gyro (go change it to 401 or Gy611) and a heli 28 years young

So i stay with the old stuff with Futaba and my other stuff i use all Neo's,Evo's and touch

Hi,

I'm actually not sure how low you can go in the computer software, but with VBar Control EVO, VBar EVO swash plate servos can be adjusted down to 72 Hz (old Futaba frequency, which 50 Hz Servos can also handle). You'd just need to do that _before_ plugging in the servos, else ... white smoke.

Tail servo, similar, 50 Hz/1.250 µs (wide pulse).

Even if it's not even nearly optimal, for flybarless, it can be done.

So if the old stuff has worn out, there are options

28 years is a number, though

Cheers

Hallo in die Runde. Allgemeine Verständnisfrage. Hat der RX7 nun 7 oder 9 Kanäle über sbus? Und welche Makrozellen sind dann die 7/9 „Kanalzellen“?
Danke im Voraus!

Über Busausgabe sind es 16 Kanäle - beginnend mit MC11 / E1CH1.
