Another overkill Truggy : MBX5T MMv3 1520 1Y 6S ;)

Ooook, that is H E A V Y :D
You've done a Thread on your conversion ?
The first time you run, just check the motor temp after a few minutes of bashing and it will be ok, my MBX5T is probably between 11 or 12 lbs...

here is my build up...http://www.rc-monster.com/forum/showthread.php?t=26750

i am actually thinking about building a second lightweight racer savage and putting this motor in it and gearing it to 40mph and then using my current frame for a new twin motor setup...

which is this thread http://www.rc-monster.com/forum/showthread.php?t=26816

ill have it out this weekend with some pics and my temp gun at the ready...

i took it out the other week for 5 mins with new gearing which i hadnt calculated and it was running very hot... i got home and worked out the gearing... IT WAS GEARED TO ROUGHLY 75mph!!!NO wonder it was running hot hot hot!

Hello guys, here is some pictures with 2.4Ghz system installed, it is not very clean with this purp stuff, but that's enough clean and secured for me










The NEU-CC 1520/1Y handles very well the truggy, with 70% punch control, it is very smooth and offers a lot of controllability. The motor run just as cool as it can be and runtimes are just insane ;) 30 min with 6S 4000mAh.
I don't regret my choice, compared to other motor like 1515 1Y or tekin truggy motor that would run a lot hotter and less efficient than my big GreenMonster
Now I'm convinced that there is no "too powerfull" motor for a chassis and that we better have to choose a bigger motor than a too light motor for a given application

30mins on 4000mah!!! So hopefully i will experience a little more run time with my 6s 6500mah batts... will keep you updated as my motor is pushing around a 14lbs pig of a truck haha

Nice pics!!! trugyy looks good... i know what i want to be building eventually....
Also what did you use on teh rear a arms to protect the shafts etc..????

30min with 4000mah.....


Maybe messing around the yard but there's zero chance that'll happen at the track under full chat under "race" conditions. If i had to guess, you'll see 15maybe 20 min max depending on track conditions/setup.

Looks pretty good though. Certainly a big motor.

4S 5000mAh setup gives 12-15min in a truggy geared for 40mph, 6S 3300mAh gives a little more for the same speed (better efficiency), so i expect to have at least 20 min runtimes under race conditions. 30 min is the runtimes of bashing, 45min-1H if I walk with the truggy in the park

[nuz69]

Test in track condition done !
19-20min on hard pushing (ratio 15/46) , motor temp after 1 run : 100F (ambient temp was 57F).
This motor has a fantastic amount of torque, it can reach its max RPM instantaneously and with 70% punch control its just soooo smooth :D
I even don't want to gear up, the ratio is just perfect for bashing or racing, and gives me the efficiency I wanted since the beginning of this project :D
Guys told me that my chassis was in fact a "prospec" MBX5T I suppose its bette then a normal MBX5T ???

Those are some good times for that big beast... you should post your findings in Talk 1520... good info to have there.

[Jahay]

nice to see your happy with yoursetup... I have just put my 18t pinion adn 47t spur in and loctited everything... hopefully it will be ready for tomorrow. I will get a vid hopefully and temp readings... Im interested to see how the motor fairs in a larger truck... (Bare in mind im only bashing so im not on throttle continouslly

Nice jumps, major air Nuz69!

[ANGRY-ALIEN]

Nice...

[magman]

nice...I run the 1520 on 5s and love it in my mbx5t

[kneedeeppow]

how would a 1520 go on a 4s in a truggy? would run times be extended? currently running 13 minutes with 4s and 2200kv.

[nuz69]

Very little, you should go for 5 or 6S with the 1520 to see a big difference.
Maybe a 1518 1800kV and 4S ? but same you should run it on 5S.
6S 1520 geared for 40mph will give best results I think.
