Are you guys talking about the holes in the red enclosure?
Those be the ones. They are ABSOLUTELY required for cooling of the speaker. Without them the speaker will overheat and die. As a bonus it allows the sound from the rear of the speaker to resonate into the cabin of the plane.

Andrew,

Maybe you can do something like this at some point.

That is a unit from Greg from Real Sound. Great guy, I talk to him quite often. The stuff he does is top notch, but he only does custom orders. I have reccomended him to some customers that want the ULTIMATE in realism. I think his stuff is better than the other two brands out there.

I am working on a Jet sound, and in fact it does sound very similar. Nice long start up. I should have a video of it by next week sometime.

Andrew,

got my "Mini" on Monday, got a chance to test it today, it's awesome!

so I am now working to design a small container to install the unit and speakers into which can be mounted on my "stick" planes.

I am thinking of making a box out of zepron foam, speakers would be mounted in the sides or bottom, holes cut and the mesh over the openings and light fiberglass over the remaining parts. the box would then be mounted to the stick fuse with a velcro strap.

still in my head, just curious if anyone else has done similar or the same

P-51 Rebuild


Guys,

I am in progress on a rebuild of my FMS 1400mm P-51. This is the star in the movie on Andrew's website. As reported earlier in this thread, I burned out my 800 watt motor when I put in a 5S battery. I have now installed an 1850 watt-capable motor in the plane and am in the process of replacing all the foam hinges with CA hinges, installing new linkage hardware, and replacing the retracts and struts. I am travelling the next several days but hope to have this retrofit done by next week.

One other aspect of the retrofit was to pull out the single speaker sound unit, and reinstall with a steel speaker mesh. It looks and sounds great.

Andrew - was hoping you could point me to some specific instructions and pictures of the modifications to the speaker covers that you refer to in the post above.

Thanks,

Jackson

Jackson,
I think that yours is new enought that it already has them. The speaker sould be sealed in the front with clear silicone, and there should be 4 holes in the red enclosure. Two in the front (if it is a Pro it may be covered by the gun card), and two in the back near where the speaker wires exit. I just had not done the mods to my personal unit. LOL

Just make sure there is no gaps around the speaker when it is installed in the plane. This will introduce some sound canceling.

Fantastic! I am not sure how you would do that, but keep us informed on what you come up with.

So from what I have read, this sound system will only work with 2.4 GHz systems?
That is sad because I have no intention of giving up my 36 MHz gear. It still works perfectly.

The reason I say it is for 2.4Ghz only is because possible RF interferance. On 72Mhz I have seen the system cause servo glitching. That being said, I do have a couple of customers that are using it on 72MHz without problems. The Ferrite Choke should eliminate most of it. I would imagine it would be the same on 36Mhz, but I have not tested it. It may work just fine, but it is something to be aware of before your first flight.

Yes, I can do that. Were your speakers sealed, or did you get them before I started doing that mod?

Thanks Andrew. It is a shame if it can't be used. I will have to ask around other users.
