What is difference between X-Frame and H-Frame?

FPV quadcopter racing becomes more and more popular, most of pilots like to diy FPV drones, but many beginners are hesitant what they choose the FPV frame: H frame or X frame? What is difference between X frame and H frame?

H-Frame

H-frames as the name suggest form extended arms from the body that form a shape of the letter H. The H-frame drones were the first drones and have continued to become popular to many over the years. They boast of very strong but heavy frames, they are capable of carrying maximum lots of FPV gear and running a LiPo battery. They have a relatively wider base guaranteeing them stable rolls. I would confidently say they are good if you are a starting FPV race due to the capability and durability factors especially the batteries of H-frame drone tend to last longer since their positioning ensures they are not easily damaged. It also makes a suitable best drone frame for racing as it offers plenty of room for easy build and modifications.

X-Frame

X-frames stand out as the big names in racing and freestyle. Configured in an X shape that characterizes its arms it guarantees stability from the centralized center of gravity. They comfortably perform stunts, rolls and flips. They are also characterized by a symmetrical pitch and roll axis. Their battery is however more vulnerable in case of a crush due to its location at the base of the done. X-frames are the best FPV racing frames due to flexibility and predictability in their handling. H-frames may stand out for beginners in FPV racing but X-frames are rated the best drone frame for racing. Other popular frames include the v-tail, hybrid X and stretched X frames that are modified for different capabilities and performances. A disadvantage of the unpopular racing drones is that they require custom motors and some parts. That could be a real hustle when you require replacements and spares.

The different frame you need to choose the different battery. For H frame, you'd better to choose long size batteries, such as Tattu 450mAh 2S or 3S or 4S 75C lipo batteries, they all fit H frame perfectly. For X frame, I recommend Tattu 1300mAh or 1550mAh 4s 95c square lipo batteries.
