A lot louder than i was expecting. It would be simple enough to add a different speaker, although the one that comes with it is nice and light.great war bird gun effect for the price you can not go wrongPrima Effekt. Bissel leise aber ansonsten OKVery loud. Not sure yet about the application for this but I will look around.Ok sound is good but operation was disappointing.
What is not clear as I read it is that this does not run from a radio channel in the receiver.
You can plug it in the receiver but is then always on, disappointing.
If it had been clear I would have spent the extra 4 euros for the required switch, make sure you get them together to avoid the same problem.
Will have to wait till the next order so wont make this build :(REQUIRES A Rx CONTROLLED SWITCH FOR OPERATION. (I used PRODUCT ID: 9107000266-0)
A great addition to my P-51. I have it installed alongside the Machine Gun LED unit (via a Y-lead). Very loud speaker.Works, however the sound is a little tinny. Could be better with a higher quality speaker and amplifier.complete fail! powered it up led comes on but no sound! Am i going to sent it back? No whats the point as the HK warranty sucks. i expect they would dispute the claim as i had opened the packet to use it! lolIn conjunction with the machine gun fire lights, this would go great with the package.I installed in in my FU109 could not hear the speaker unless you have it on your bench at home waste of money when using out side need amp to make it work if you were to install on a 2-4 stroke forget it just extra weight. Could not recommend needs to be louder.
