homemade 1/10th monster truck with steel solid axles, proline devastator tires
Here some details about how i built my 1/10th monster truck
well i wanted to use the nice 2.6 tires proline devastor !
as usually, i want a strong driveline, strong axles and linking arms. So i choose the mugen mbx7r eco front and rear diff with the diff box. i will built the axles and arms
i wanted to share how i do it. note that i'm an amateur, i learned to arc weld by myself for RC ! i also now weld tables and shelves for my home.
those are my power tools. i use 2 grinders with adjustable speed ( basic ones turn too fast ! ) : 1 grinder to cut , 1 grinder to smooth the surface
i also have a good old dremel too
for this truck i use a small tube 20x20x1.5mm, cheap stuff, zing coated ( not the galvanized version where you need to remove the galvanization )
i made a aluminium part because the diff crown sticks out. the lower steel diff holder is 2 mm thick

wheelbase will be 32cm, might be a bit short, but i want a agile truck to flip !
motor will be 1/8 sized 2350kv trackstar, or maybe even 2200kv neu motor running on 4s ( because the truck will be heavy )
chassis will be the one from my older monster truck. but i will not keep the cantilever suspension.
i will no re-use the old axles because back then, i used the weak hobao hyper 9e transmission ( it had weak 12x8x4mm ball bearing all over )
i like this kind of simple chassis to save weight.

i always make the same reply : i'm short of time too and would not have the time to built it for somebody else ! days don't have enough hours !! i got many things going on and i wish i could do more !

Holy cow! This is awesome. Nice work on those axles.

thanks for your understanding man, any welder could do the job, just show him those picture. the rest requires more work : the steering knuckles are more complicated : there are more parts
holding the ball bearings and those are not easy to adjust perfectly. i 'm far from perfection and had to file and cheat a bit to get a nice free steering !
i got many projects that i want to do ASAP !! it looks like this :
- 1/10th homemade MT + stunts/freestyle video with various bodies
- 1/5th homemade MT +stunts video
- 1/7 cen reeper truggy on 6s + some jumps video then on 8s + speed video
- arrma notorious with some mods + full stunts video
- 1/8th buggy decaflip attemp + video
- 1/8 xray stunt truck seven flip backflip personal record attempt + video
- 1/7 cen reeper rebuild with longer suspension arms
- xray truggy rebuilt ?

a bit more details about the steering knuckles. note i let a pro mill the basic ball bearing receiver. he didn't know that RC baalbearing are soft and don't like to be squizzed in to tight ! i had to drill the holes to widen them !
i chosse to weld the round baal bearing receiver to a square tube for many reasons :
- it's easier to weld to 1 piece than to 2 separate parts !
- i'm sure than the upper and lower "deck" are parallel !
- it hides a bit the universal joint, i like it

i could work more and to get a first look
front axle : i changed the servo holder to a lower position to use a low profile servo : this cheap one from hobbyking has 12kg of torque and it worked OK on my previous MT.
i can use a single upper arm thanks to my design : it's the lower arms who keep the axle centered.
i use a redcat 1/5th upper arm i had laying around !
this is a close up of the steering knuckles and their parts
i will try those savage shocks even if they use only 3mm shafts : i like the look they give to the truck and their low weight. i use the same shocks on my 1/8th monster truck and their's fragile plastic rod ends broke sometimes.
As i don't need all the 55mm of suspension travel, i will add the soft rubber block to help the plastic rod end to get less stress on crashes.
the truck might look ab bit too wide, i will see how the proline wheels + devastator tires will look to adjust the width ( with hex extensions )

This 1/10 MT look good. Il like your style of building.

i received my proline devastator tires and the brawler rims : nice tires ! it's cool to touch them after seing them for so long on youtube ! they are small and soft !
I use a mugen 1/8 buggy transmission and 17mm hex so i modified the brawler rims !
i took an old 17mm hex old buggy rim and cut it to screw it on the brawler rim using 3mm nuts : it's not finished yet but it works !
to be continued..
