Hi guys

I have a 46cc petrol engine that is going into my new model , iam new to petrols/gassers but have done a ton of glow motor running
I would like to know where i should mount the cdi ignition unit ( as fare a way from servos , receivers or batterys etc) iam running
at Jr x9303 2.4ghz radio if the helps

Any help would be great

cheers

If you have room, mount it on the side of the engine block and put the battery on the other side, Use Velcro and pull ties to mount it. Do not hard mount with screws.

Is there a reason for not using screw mine has little tabs on the ends looks like for using screws

VIBRATION

And if you have a mishap you will have a better chance of not breaking the ignition box.

ok thanks guys

Please forget all you know about glow engines. Gas engines are a different breed and need their own approach. Small fry is glow, and about 26cc and upwards is the realm of gas engines. Larger engines are larger stompers, so the propulsion pulses are heavier. You need to construct your plane and parts accordingly. Mount electronics in foam, so it is protected from the large vibration pulses, which are mainly there because of the very light airframe structures now abailable, and becoming increasingly popular.
Velcro mountings are very effective in protecting your equipment. So is foam mounting, though it has the drawback of less cooling.
Learn how to handle vibration prone applications. Learn how to live with, and prevent radio interferance. Learn about mufflers and carb tuning. Once you do all that, you'll never look back.
