ARRMABrushless System & Power Module Boost Box, ARA210005

Was an easy install and great packing and timely arrival.

Zoooooooommm , almost too fast. Full throttle from a dead stop does a backflip in place... not for novices but unreal if you can keep it on the ground. I had to set my controller to 50% max power for off road runs

Great motor and esc upgrade. Unfortunately, this one I received was an open box missing hardware and the additional spur gears.

You should definitely get a wheelie bar with this... took my Granite 4x4 Mega to a whole new level. I like that it comes completely assembled and its easy to install, plus tons of step by step installation videos online... also would recommend upgrading the motor mount that comes installed with this, the factory mount tends to bend on hard landings. I upgraded mine to the blue mount in the pictures

I had a stock Granite 4 x 4. This kit just screwed on very simple and now the truck is a monster. Almost too fast for its own good. Lol. The instructions were not exactly step-by-step, but they were close enough to figure out.

Fast shipping, easy install on Arrma Senton 4x2, easy pairing with remote and extremely fast. Overall no issue.

The media could not be loaded. This boost box is an absolute monster even on 2s lipo!Words can’t explain how killer this boost box is! Just gotta buy one for yourself to find out!would definitely recommend a wheelie bar and a spectrum tuner so you can set your brake % and punch level. So worth the price! Just be prepared to break parts haha!

It wasn’t a perfect fit which was probably my fault but it had great speed and torque and was plug and play
