testing out the new HQ 7x4x3 tri prop on the cinematic 7 running mb primo 2208 2150 kv on 5s, Have to say these feel great, i noticed no deflection on hard throttle punch and over all very similar to the dal 7056 tri prop, good to see other prop companies giving us more selection of 7 inch. As you can see from the video we got a ton of rain this year, love seeing all the different colors instead of just the normal tans here in the desert. If your on face book find my group Multicopterbuilders mid range mountain surfers.
