This is what I would do:
But both the V 1 RR and Reflex.
Use the K Factory hopups come with Reflex to hopup
your V1RR ( like Chassis, upper deck, rear brace, alloy pulleys,
fuel tank, shock towers...... ).
Put toghther the remaining reflex with the remaining parts from V 1 RR, and sell it on eBay.
This will be cheaper is you were to buy a V 1 RR and all the Kawahara stuff.
, especially considering brand new reflex NT
has lately been sold on eBay for about $220, that's a great way
to buy hopup parts for any V 1 R
