Didn't you already expect this to exist? It doesn't yet because things aren't quite as simple as pulling the arms out on the TP3 to fit larger props. We focus on refined designs that are built with more purpose than typical general use patterns. The TP4 will be refined specifically for the 4" spec build we're working on with our 4" specific motor. This same general design will likely be offered in 5" but we don't recommend a 5" ultralight. It's just not worth it. We don't recommend using any motor smaller than a 2207 or 2305 for 5" props. You're just giving up control performance by going smaller. That being said, there are some very interesting props coming soon and we'll continue to test for the performance we're looking for in a low weight package.
