Perhaps an Admin. who can lock it yet still access it at any time for updates as necessary?
Most PC's come with a "Find" function. If you press and hold the control key "Ctrl" on your keyboard and then press "f" you'll get a tool bar at the top of your page. You can then type in the word you're looking for. If the word is listed on that page it will be highlighted. Pressing "next" allows you to quickly scan each listing for that word on any given page. The tool bar stays at the top of the page until you close it, so the command will carry through as you navigate to succeeding pages by pressing "next".

Those definitions help me out alot!! Is there any place for assembly instructions for electronics that I can look at while assembling tomake sure I am doing it right?

Holy crap!!!! My head is spinning. I just read through this entire thread. This is some good stuff. The amount of info contained in this thread alone is great. Answered a lot of questions that I had. Thanks to all that have contributed to it.

This thread is absolutely great, I have learned so much along with the reinforcement of basic principles. The last vids show what is totally possible and can set the newbee's sight on what is possible. I am moving from nitro (which I have built for over 10 yrs) to electric. If you have the bucks, the UAV or FPV are a dream come true.

Are gearboxes used on both outrunner & inrunner motors ? Does the gearbox come automatically with the motor sometimes or you have to buy it all the time ?
Last why would you put a gearbox on an motor that could run without one - if that makes any sense ?
Thank you

V, this thread is mostly intended to be a compilation of terms that new pilots may find useful. I'll answer your questions here, but in the future it would be more advisable to use the site's search function and then start a thread if you don't find answers.

Both inrunners and outrunners can use gearboxes, but it's much more common to use an inrunner. This is mostly because outrunners can be made with low-enough Kvs to drive props directly, whereas inrunners generally have much higher Kv values.

Some motors do include gearboxes or are sold as package deals, but in general they're purchased as separate components.

As for gearing a motor that can be run direct-drive, it's all a function of effective Kv. You can technically run a 3500Kv inrunner with a direct-drive prop, but it would have to be a very tiny prop to keep the current down. By using a gearbox, you can reduce the effective Kv of the system and use bigger props that are suitable for more applications. A 2:1 gear ratio would give a shaft output of 1750 RPM/volt with the 3500Kv motor from above; 5:1 would effectively be 700Kv. Unlike brushless outrunners, inrunners with gearboxes give you the advantage of optimizing the effective Kv by simply switching pinions. The tradeoff is increased cost and more parts to break in a crash (though you are less likely to damage the motor itself).

Again, if you have any further questions or comments on the subject feel free to PM me to keep this thread from getting too cluttered up. You can also use the site search feature; it's surprisingly handy.

Wow TP16 !!!
Now that's the kinda response that hits it out of the ball park completely !
One more thing that I can scratch off my RC knowledge list
Thank you very much

I see the term "brick" used frequently in rc forums. The way it's used in a sentence seems like it has something to do with a receiver (Rx). I did a "Search this Thread" and didn't find it. Can someone provide a definition? Thanks.

Got me? The ultra micro stuff from Horizon hobby has the receiver, servos, and esc all in one unit. They may be referring to that? Or they could mean they burned it up somehow and bricked it.(turned a working piece of tech into a non working piece). Other than that I have know idea.

brick is used to mention an assembly that includes receiver, esc and servos, like horizon's 6400 used on ultra micros like the champ, sukhoi, mustang and the like.
the idea is to simplify the installation so 1 unit mounts easier than several of them separately-and ends up being lighter, too.
