Diatone 2019 GT R239 vs Diatone 2019 GT R349
Due to the larger size, robust carbon fiber frame and more powerful motors, the the GT R349 has almost twice weight of the GT R239. Another major difference between these two is the battery type. While the GT R239 is powered by 3S LIPOs the GT R349 by 4S ones. IMHO the GT R239 is suitable for indoor practice and the GT R349 for outdoor flights (it needs more space to unleash its full power.).
