Bruder D5 1 day build
ive been wanting a d5 build for awhile,but always forgot about it,or put it off.....ect.
we all seen em done before,nothing new right. i chose the same tamiya 4 speed gearbox model 70168 as most do,but id went a different route with controls and the blade.....and the sprocket. i installed a complete $50 heng long tank tx/rx/mfu system with sound and option to install lights later. HL route offers 1 stick tracks,leaving the turret channel open for the blade. and i have on the tx volume control,and the smoke button is on/off control that can be used to activate lights.......all for $50 i have no room to spare under the interior after installing everything.(speaker has been moved inside) i went with 2 18650 samsung 25r 3300 mah lion cells for 8-12 hr runtime before needing a charge.place in a $3 ebay battery holder. i designed and 3d printed some new drive sprockets with longer teeth. also designed the servo post and pivot system for the blade. i chose a standard futaba s3003 servo,ripped out the servos esc board and pot,modded for 360.....soldered on motor wires. so my servo is basically a gear motor that looks like a servo. when the blade reaches max travel it stalls the servo. https://www.youtube.com/watch?v=66zd...0K9JdN_a6Mkqb8 Bruder d5 by Nick Pellegrin, on Flickr Bruder d5 by Nick Pellegrin, on Flickr Bruder d5 by Nick Pellegrin, on Flickr Bruder d5 by Nick Pellegrin, on Flickr Bruder d5 by Nick Pellegrin, on Flickr Bruder d5 by Nick Pellegrin, on Flickr Bruder d5 by Nick Pellegrin, on Flickr |

Re: Bruder D5 1 day build
thanx
it came out pretty clean.i just designed a skid panel to protect the gearbox.....nothing scale but should work.ill get pics n update soon. the d5 performs alot better than i expected.i put 8 hours on it yesterday. |

Re: Bruder D5 1 day build
GREAT conversion! A very different approach utilizing the tank controller.

Re: Bruder D5 1 day build
thanx guys
i just built a 2nd d5,but this time i used the 2x12 sabertooth.....it just fits under the interior.its the first time ive used a sabertooth,i like it .....but ive gotten used to the old heng long.but the sabertooth is a true variable throttle,the HL unit it more like a 12 step speed control,but i will say the HL has a easier to control low speed over the sabertooth.and steering in reverse is backwards on the saber aswell.ill see if thats something that i can change.im happy with both though,id guess the real benifit of going the sabertooth route is the ability to add servos and assign switches,and wide variety of transmitters out there.the advantage of the HL budget and getting the job done.i almost prefer the HL setup.....hard call though. |

Re: Bruder D5 1 day build
Great results! I built one few years ago, but original sprockets are two short and slip every time, I also burnt the tamiya gearbox motor. Was wondering where can I get the sprockets with larger teeth?

Re: Bruder D5 1 day build
i 3d print them,ill eventualy put them on thingiverse,ill try to figure out how to load the stl file here
i used the teeth set from this sprocket. https://www.thingiverse.com/thing:2616603 i use these motors https://www.pololu.com/product/1117?...Cg9gJJwNMwXfdY Last edited by igotit; 11-22-2018 at 11:00 AM. |

Re: Bruder D5 1 day build
With a Henglong and a Sabertooth, i'll be interested to see which you prefer after the machines start getting more hours.
I remember reading about the bruder sprocket slip being fixed with either cutting radial slots that ziptie pieces can be inserted and trimmed, or axially drilling holes for drive pins depending on the track design.

Re: Bruder D5 1 day build
thats your work.....thanks for your contribution.
im working on making the teeth just a tad bit longer to see if it helps.ive abused my d5 over the last few days and really stretched the tracks out,moved the box back to tighten up,and stretched some more.hoping longer teeth will do the the trick. |

When you do get the longer teeth done, I look forward to seeing it. How's that gearbox holding up? I started with that, then went to the servo drives. I only had a few hours of run time on mine before I stripped the gears. I couldn't figure out a way to keep the force that the tracks were applying from putting excess pressure on the shaft, & making it easy to booger the gears. |

once i get this sprocket dialed in ill publish and share it. right now im working on a delta loader,originally had a tamiya gearbox in it,never ran it.yesterday i designed and printed mounts for 16mm 150 rpm gearmotors.done its first test drive tonight.....and i have to say im more than happy.ill make a vid n post a seperate thread soon. the problem with the delta builds are lack of room for batteries,i think i got that that solved thou. also have the bruder tracked loader arriving in the mail soon. for some reason im in bruder mode....lol. |

Re: Bruder D5 1 day build
I LOVE them Bruder mods! I have done 5 successfully, & a couple of failed attempts!
The fail for me was the delta loader. I DID manage to get a skidsteer successfully converted. the others are the D5, the Bruder Mack dump truck, the tracked loader X2 mine & one for a friend, the L574 loader (NOT so successful...................but it did function, as well as the Bruder D10. The 10 I sold to a friend of mine for cheap. I couldn't get a reliable drive system that make er move. I fried several gear motors, as well as servos in er before i gave up. He put a HengLOng tank transmission & motor in it. That thing seems to work well now, but isn't heavy enough to push much. After he ads more weight to er, he may have a good lil machine. I may have gotten a bad box. I gave 2 of them transmissions away after the first catastrophic failure I experienced. I look forward to seeing your builds as they progress.

Re: Bruder D5 1 day build
I've found that I get 8-12 hours of runtime on a set of Bruder tracks. Either on the D5, or the Bruder tracked loader, before they are so stretched that I have to replace them due to slippage.

i tested a longer teeth d5 set today,every other tooth has to stay the same length as your buddy designed.....but even on loose track that are stretched rarely ever slips,stalls the motor instead when it gets in a bind. once i tweak it ill get you that stl.you need it with hubs for tamiya gearbox or something else? on the delta loader,i just installed 2 16mm gear motors in mine to save room over the tamiya gearbox route.im verry happy with speed and power.....plus $8 shipped for both gearmotors hard to beat. ill get a pic of that tomorrow,top end still in peices and need work. |

Re: Bruder D5 1 day build
the cool thing i did with the delta is recessed the 16mm planetary gearbox into the drive hub 8mm in.....similar to a real loaders drive hub.

Re: Bruder D5 1 day build
That delta loader is looking good! That makes me regretful that I tossed mine out earlier this summer.

Re: Bruder D5 1 day build
Those are looking great!
I really like that delta skid, any chance of sharing the stl files and motor ratios?
