This chassis is made using 4 mm 7075-T6 aircraft grade aluminum and anodized clear. On the advise of Of our test team We have redesigned the rear section of the chassis and added 20 mm more material to cut down on chassis flex. this material is time tested to provide much more regidity to the chassis. We have also added steel droop steel stops as this is a major wear point of any chassis on the market. NOTE::::::: FOR THE GUYS WHO STILL HAVE THE V1 LAND V2 MODEL TALION, You will need to order the V3/V4 KRATON STYLE CHASSIS. The bolt patterns on the TALION V3 and V4 chassis are different.
