Brushless Beetle

I’ve installed the 10.5t Hobbyking brushless into the Blitzer Beetle , the included ESC wires were to short , so a little extension had to be soldered on, at first i planed to do a direct solder to the motor , but since the cables were to short i used 4mm bullet plugs. the installation went without a hitch. Both Hobbyking components seem very well made , glad i got the extra sensor wire though as the one included with the motor is a bit puny.

the Blitzer Beetle , now brushless 😀

also did the shock tower reinforcements with m3 threaded rod  and shock ends. its really simple , just cut the proper size and screw on , also keep a m3 nut on it so you can rethread the cut end with it . if i find some aluminium pipe small enough ill put that over the m3 rod .

reinforced shock mount.

i’ve only test driven it inside but first impressions are very good, might need to add some weight in the front .



Bling and Horses

You know how you say you will not spend more money anymore on RC, well i tried and failed miserably , again.

these two packages arrived this week , the first on monday , the second on thursday .

lets start with the first :

The ESC and brushless will go into the Blitzer Beetle , the receiver pack into the GT3b , the rest was padding, oh and xt60 connectors .

Upgrade posts on the Dual Hunter and Blitzer Beetle will follow shortly.

Tungsten balls

Finally, after almost a month and customs the parts for df03 melted diff. i was recommended to change to acer tungsten balls .i also got some new plates and some aluminium tape , which in the end triggered the customs check.

Here’s what arrived :

1x Tamiya 51248 Spur Gear Set DF03

2x Tamiya 50880 Ball Diff Plate Set

2x T004 Acer Racing Tungsten Carbide Diff Balls 3.0mm T004

also arrived but not directly connected to the Diff

1x HPI Racing Aluminum Tape 50×2.5m

2x Pro-Line Racing 1070 Dirt Hawg II 2.2 tires for the Blitzer Beetle (only one set pictured)

1x Robinson Racing13 Tooth32 Pitch Pinion Gear RRP0130 for the Blitzer Beetle (not pictured as its already installed)

df03 diff rebuilding material and some tires



Here’s the result of the first run of the DF03 with ezrun 8.5t  . The diff was probably not tightened enough.

Adventures in Brushless land

The weather is lousy , but things are moving along .

over the last few days a couple of things arrived :

– XT60 connectors for switching over from Tamiya plugs

– an used Ezrun B5 combo (8.5 turn brushless motor with a 60 amp ESC)

– Five Stars FS7039 Steel main shaft for DF03 Slipper clutch all the way from Champ International JR from Osaka Japan, this shaft seems to be the only thing which is wrong with the df03, as it replaces the aluminium shaft of the original tamiya kit . They also seem to be very hard to find out of Japan. 

– Tamiya 53922 05pinion Gear 23T,25T

– Tamiya 53925 DF03 Slipper Clutch set

– and some bearings, but thats another story.

components to make the DF03 brushless ready , with the holy grail , the Fivestars FS7039 Steel main shaft for DF03 Slipper clutch

After Mojca became a master of soldering and converted over all the XT60 plugs , i was ready to go to install the Ezrun 8.5 into the DF03.

EZrun 3650 is a full size 540 motor, with even more torque than the 3650s finned motors which are 380 motors in a 540 can

The Fivestars shaft is a perfect replacement , for the Tamiya part , installation was flawless , except that i forgot the two shims on the original shaft , so i had to take it apart twice 🙂

DF03 slipper clutch is necessary for a brushless motor. keeps the torque at bay

After everything was wired up , a problem appeared . if i kept the ESC and the receiver on the side opposite the servo , i ran out of space. that might work on a DF03ra chassis which has a sedan body , but the DF03 buggy body is tiny , so i moved the receiver to the other side and now it all fits .

no way to get the body on.

everywhere you look for pictures of the ezrun esc,  no one shows you the pair of resistors which are rather large (almost the 1/2 size of the ESC) .

now it all fits , even with the Turnigy 4000 mah lipo and its thick cables

i’ve tested with the body on and its perfect . i need to tidy up the wiring a bit its basically done . judging from the acceleration test in the living room its wickedly fast , definitely faster than the blitz. Its using the 82t spur wheels included with the slipper clutch and  23t pinion. now only if the weather will clear up so i can get some driving done.
