This week I’ve been preparing my tiny whoop fleet for the winter season. I currently have 4 tiny whoops built up but over the years I went through much more. I’ve tried various different frames and I thought it would be useful to share my experience as well as collect some basic information in one place.

65mm frames

65mm frames are the best choice for tiny whoops you are going to fly indoors. It’s also the standard size for tiny whoop racing. There is no best frame for everyone in this category. In order to pick the best frame for you, you will have to decide whether you need more durability or more performance and flight time.

The thoughest frame of them all is the original Meteor65. I think it’s a good choice when you start learning to fly tiny whoops and match this frame with lightweight analog components to keep the weight down. It will handle crashes the best. Once you outgrow it and you are ready for a less durable lightweight frame I would recommend the Mobula 6 2024. It’s almost as light as the lightest frame here (Meteor 65 Air) but it’s a bit more stiff/durable and tunes better. You will also need to go with the lightweight frame option if you are going to build digital (HDZero/Walksnail) whoop as those need to save every gram possible.

I don’t have a good reason to recommend Meteor 65 Air or Meteor 65 Pro frames. They might be good for some specific use cases but I tried them and I’m not building any new whoops with them. Meteor65 Pro with its larger props is in a weird spot where I would just go straight to 75mm frame and 40mm props. Meteor65 Air is only 0.1g lighter than Mobula6 2024 but I had so much problems tuning it that I don’t see it worth it.

The old school Mobula6 and Cockroach V3 frames are good alternatives to Meteor65 for a tough build but I think Meteor65 has an edge on them when it comes to durability.

75mm frames

75mm frames are the best choice if you do most of your flying outside. You can fly these rigs inside but it will be much harder compared to 65mm whoop. I think in this category the choice is much easier: Meteor75 Air and Mobula7 V4 are both great options. All my whoops in this category are digital so I slightly prefer the lighter Meteor75 Air frame. However, I can tell from experience it’s less durable than Mobula7 V4. The ducts will break on it and it’s pain to glue them back. If you are building analog whoop and you can spare some weight you may want the Mobula7 V4 for durability. The ducts on it will take a lot of hits. The weak spot is the battery tray but I would put some E6000 glue there and it makes the frame bulletproof. Let me know in the comments if you’d like me to add some photos on how to reinforce this frame.
