I must say the '4x4 ARENA' track which i've recently completed4x4 arena 1 build is very astounding to drive around.  Not only the new track layout offer 50% more challenging obstacles to conquer and also more area to explore plus the surrounding environment are visually amazing which keeps rock crawling activiry more alluring to enjoy.  The most stunning off-roading show happens at night!  Since i've equipped various area of the track with different LED lighting colors which give out different 4x4 arena 2thrilling visual vibe through the bridges, claustrophobic cavern and other parts off the track. These give miniature R/C crawling worth the excitement to stay for hours on the track and being mesmerised for its realism.  Last night i spend from 7.00pm till 12.30am midnight crawling around and i still haven't able to finish complete tour around the track due to challenging obstacles and skills breakdown but overall i 4x4 arena 3was like 'woww!' can't describe in words how aesthetically beautiful it was to drive around in this barren world of miniature 4x4  especially it was me myself who build it!  I felt my time spending building this track expansion was spectacularly worthy!  Check out my crawling activity through the gallery link below:
