1. If for any reason you are unhappy with your Bat Frame Kit purchase, simply return it in it's original condition within 2 weeks of purchase date for a full cost-of-purchase refund (minus shipping cost).

2. If you break your Bat baseplate or top plate within 30 days of date of purchase, TMac will send you a new one for free! You pay for shipping. Contact TMac directly at and send an image of the broken plate(s) along with a snapshot of your packing slip you received with your Bat Frame Kit.

NOTE:  Please do not expose your 3D printed frame to high heat for an undue amount of time.  Exposure to high heat (direct contact with soldering iron, heat gun, enclosed vehicle during hot day, etc.) will deform and damage your frame.  This damage is not covered under warranty.  The heat distortion temperature (HDT) of your frame's filament is approximately 54 degs Celsius = 129 degs Fahrenheit and temp's approaching this should be avoided

As of July 25th, 2021, now printed with carbon fiber PLA filament for added strength, durability & less weight!

Should you have any questions regarding your frame, assembly, build, and/or tune again, email me at . To help with your build's tune, the free Micro FPV Tuning Guide is available for download here!
