Default Evolution 26GT Throttle servo on firewall?

I know some say don’t do it some say it is ok. I have seen it on the big 3d planes the question is placing the throttle servo behind the firewall. I have the Evolution 26G the old version. Some say to keep it 12 inches away. Looking for input. Also what about driving the throttle with some like a Hitec 81 micro servo?

so you know you should not, but you rather would not.
The decision is yours, so is the risk.

I have one plane 12 inches away and the other with the servo on the side of the engine box. No problems. Those 81's will fail if the get in any kind of a bind. A standard servo does not weigh that much more and they are cheaper.

and what does that tell you?

Vlach, the ignition producer and expert says to keep components apart at least ?? inches. He is a fool of course, because you got lucky.

On our 2.4 DX7 systems -it really seems not to matter- a friend is using his rx battery (2,A123 cells ) as also a feed to the ignition - no regs no filters - just hooked up -I have not tried that test but he is convinced it works fine - and I don't doubt him.

And I'm the "friend" (thank you, Dick.... ) and I've never mounted a gas engine servo ANYWHERE but **on** the engine box. Until this season, ran only JR PCM on 72Mhz, and didn't have problems. I don't deny that the manufacturer makes recommendations that they believe are "guaranteed Safe", and I think that's a good thing.

I am not the ONLY person that has installed servos on the engine boxes.... in fact, if you polled for that question, I think you'd be surprised at the responses.

And yes, so far, the direct-connected A123 battery is working on my RC-EXL ignitions; I cannot state whether they will be okay with any other brand or configuration of ignition.

I also am only running Spektrum 2.4 modules on my JR 9303 using either AR7000 or AR9000 receivers.

I'm going to be the next. However, I'm running it on a DA-50 so I'm going to still use a regulator and I'm using the XPS system and soon the futaba system for a review plane / module sets. One of the greatest things about 2.4 Ghz is the frequencies are higher than the RF noise of the motors...
