Electric Stunt => Gettin all AMP'ed up! => Topic started by: Randy Powell on April 02, 2013, 03:43:37 PM

The thing I've discovered about going electric is you look in the nose and think, wow, there's sure a ton of room in there. then you start putting all the stuff in there and suddenly it's cramped and you wonder how you are going to get all the stuff in there.
-
I had that happen with my Infinite Jest it looked like I had a clear half acre of room in my compartment and then all the wires, esc, timer, CAP pack, arming plug, and timer leads filled that area up incredibly fast.
-
No wonder you guys shorten the wires as much as you can.
-
yeah Randy, its amazing,, and then you have to figure out how to route all the stuff,, and then leave room for movement on the battery,, yeah, its a whole different set of challenges,,
-
Don't forget that all those wires and "stuff" inpedes the cooling airflow.
-
Twice I've been the systems lead on projects where I spent the first year of the project abjuring the mechanical designers to pay attention to the cables, and the last six months muttering under my breath about where in @#$% to put the cables that were overlooked.
Everyone forgets cables, until they have to find homes for them.
-
I made my first one 3" wide. I'm glad I did. A scale Gee Bee has some appeal as an electric stunter. It would have enough room.
-
Sure enough, Howard!
It's funny: when I was a kid, I bolted two maple rails to the engine lugs of my 35 and then glued fuse sides to them.
After a gazillion years, we figured out that skinny, twisty fuselages don't fly as well in the wind as wide ones with their better stiffness for the same wood weight.
I even had to relearn the same lesson again in RC! Duh-Oh!
Now we can add ease of packaging to the list.
Of course, that skinny, slinky aesthetic sure looks good HB~>
take care,
Dean

I've got the ESC sitting in the mouth of the cowl so i assume it will get some cooling air. I have another plan to route a ton of air through the nose and cool the other stuff.
Paranoia is a survival trait.

Howard,,
no really you are so right!
I have one 90% drawn up for electric it works pretty cool,Battery is mostly vertical in the area just aft of the cowling,, , lots of room,,

....and you wonder how you are going to get all the stuff in there.
Try this...

Peter,
That is perfect.

...That is perfect.
Well, kind of... As there remains no other opening than the top cover, all components have to be installed through it. However, given the amount of added stability of the nose its worth the effort of fiddling a couple (or more) of minutes when first removing the +/- 1 in adjustable battery tray and then squeezing in both the motor and the ESC.

My compliments as well, Peter.

I like the clamp for the ESC.
-
That is perfect.
The illustration is certainly perfect. Thank you for doing that.

Looks "Swiss-made" to me #^

What design is that ?

Weigh the wire. Its super heavy!
-
Robert,
Yes, it is. but it's also bulky.
-
I have mine apart right now so I thought I'd show the set up. The motor is removed, it is a front mount E-flite Power 32. The battery floor is removed in one photo and installed in the other. I flew this in the 100 deg. Muncie sun last summer so I'm sure it has plenty of cooling. It pays to plan ahead on this stuff and ask those who know, in this case Paul and Norm.
-
You do not need a lot of room, but you do need a plan and you must find a way to secure the bits out of the way...
-
I'm still working on how I'm going to hide the arming plug and start button. But I'll get there. Thanks for the pictures. They help.

Peter,
I liked your ESC mount so much, I stole, er, borrowed it. With some modification.
