Default My Ravenous Rush 750

My Ravenous Rush 750
With the help of Scott, Bryan and the rest of the AleeS Team forum guys, this heli has been a joy to build from start to finish. The innovations Charley built into this heli kept me impressed with each step. When it came time to wiring it, I knew I had to do it justice.

Build Thread:
https://www.helifreak.com/showthread.php?t=489014

Since my earliest builds, I have always been very careful to isolate high current components (ESC, motor) from low current components (Receivers, gyros, servos antennas). Initially I thought that may be difficult with this build, but it turned out Charley had given me exactly what I needed, as usual.

Left Side





I was able to place the ESC right next to the motor and keep the ESC lines short. It was also important to me to be able to easily disconnect an ESC plug when I wanted to do setup. With this setup, I can easily pull any of the three lines.

ESC with wire disconnected





Also, if you notice, the canopy has a nice ventilation hole right on top and I made sure the ESC heat sink was right in the path of that air.

Ventilation hole in canopy





I made the battery connections a little too short on my Logo 600 build and I later had to lengthen them because they were getting stressed when I connected and disconnected them. On this heli, I was careful to use long natural curves that allow stress free connection and removal. It also makes it easy to move the batteries to adjust the CoG.

Right Side





When it came to mounting the VBAR and sensor, I needed a nice protected location to hide all the VBAR wiring and a nice stable location to tuck the VBAR sensor.

VBAR Wiring





I sheathed all the wires to protect them and used nylon ties to hold them in place. I also made a little riser for the VBAR wires to hold them in place without stressing them.
VBAR side view




Notice in the above pictures that I moved the front sat to the side a little on the front mount to make it easier to plug in the USB for setup. I moved it back for flight.

Front Sat centered






I was careful to put the sats at 90 angles from each other, far apart, and at locations where both could never be blocked by the heli at the same time.

Sat placement thread:

Rear Sat






The Elevator Servo and tail section were built to plan and required no additional thought.

The overall heli came out great and it fits right in as the Flagship of my fleet.

I had a scorpion Backup Guard tucked in under the ESC, but I will be replacing that with a capacitor pack or NiMH battery pack in the same location.

I will also most likely be upgrading the canopy mounts

Thanks Charley for a design well done! Building this was a blast and your team reps are awesome!

Looks great Rick! I love the hidden wiring, looks like you took close looks at my build...

One little suggestion, use some fuel line, split it and CA it to the frame edges where the ESC leads pass the edge and where the packs sit on the lower frame edge.

Look closely, you can see black edge guard on my frame in those places. Just a little extra insurance. The ESC leads don't touch, but may vibrate a little and may touch, the packs sit on the straps, but this will keep the straps from cutting on the cf.

WOW! They are VERY similar. Actually I didn't look much at other peoples builds because designing the layout is a big part of the fun for me. I did ask around a bit for the sat locations because I couldn't find a good spot initially.

As far as the split tube for the ESC lines, mine are not close so I wasn't planning on protecting them, but it is a good idea and I will watch that area.

Under the batteries, I applied velcro to protect them from the frame. The side benefit from that is that it allows me to use the same battery in my TREX 600 if I want to.

Putting holes in the ESC heat sink was a nice touch. I hadn't considered that.

I had the BUG on the underside of the ESC. Where do you have yours?

Rick

I stack the Bug on the rx battery on the front tray for now, but may move it to the back of the rx battery tray.

Wait, so you have a BEC, rx battery, and a BUG?

Not using the Jive BEC, just a 2S pack and a BUG.

Some guys run the Jive BEC, with a slave cable and a 4S Eneloop pack and a BUG, nothing like backing up a back up. When there is $2500 in the air, you can never have too much insurance...

Looks great! So you're going to set the ESC on top of the battery pack that will replace the BEC? I like your setup but I myself will be running an additional flight pack.

Me? No, I will put the 2S receiver pack on the front facing tray where there is a KDE strap holding the ESC leads from flapping, and then I will put the Scorpion BUG either on top of the receiver pack, or on the back of that tray. I may mess with that tonight, and post a pic.
