As there has been more and more interest on the forum with regards to converting 1/8 scales, I decided to do another conversion for those who are just getting into brushless electric. The goal of this project is to convert a 1/8 buggy at a low cost, using (mostly) easily available components. You'll see that the conversion is a relatively simple process. The power system I am using for this project will work well with any 1/8 scale buggy, truggy, or MT(assuming you gear correctly).
I chose a Hyper 7 buggy for its low cost, parts availability and durability. Big thanks to psunitro for hooking me up with a deal on a very clean roller for this conversion.
Other parts used for the conversion are
rc-monster Hyper 7 motor mount -$45
rc-monster battery tray $35
Castle Mamba Monster Max ESC $165
Neu 1515 1Y 2200 KV motor- currently available for $230
NOTE: It is more cost effective to run the MMM ESC/2200KV motor combo for $279. The Neu motor I am using is slightly more powerful than the motor in the MMM combo. My original intent was to use Medusa Research's new 36-80 motor but it did not come in time for this conversion. I'll drop it in once it arrives.
Maxamps 6000mah 5S 25C lipo-You can run any 4-5S pack with this motor combo as long as it is 20C or greater and 5000mah or greater in capacity.
JR Z650M servo $50 I had a new spare that's been sitting in my pit box. It's light at 1.6 oz and has plenty of torque to turn the buggy wheels.
13T hardened mod1 pitch 5mm bore pinion $13
Pack of 6.5mm connectors $10 for 3 pair
First order of business is to change the diff oils in all three diffs. Due to the higher power of the brushless motor, the diffs will tend to "unload" if the oil is too thin. I went with 10K-10K-5K front center rear to start. Removed all the brake hardware since we will use the motor as the brake. Many folks like to keep the mechanical brakes so that they can adjust front brake bias. My goal is too keep weight low and I'm also used to driving with the motor brakes.
Installed the center diff with new motor mount. As you can see the servo tray needs to be modified to remove the throttle/brake servo pocket to clear the motor mount.
Servo tray trimmed and ready to install steering servo.
Installed servo and mounted motor to check for clearances.
I do have an issue with the massive diameter of the finned Neu motor, the rear chassis brace does not clear it.
The simple solution is to offset the brace on the diff bulkhead by about 5mm.
Now it's time to play with where I wanted to mount the ESC, receiver, and battery tray.
I then realized I ran out of 6.5mm connectors for the MMM esc, and I lost the servo horn for the steering servo. I'll have to make a trip to the LHS in the morning.
More tomorrow.
