Sounds like a fun challenge. Keep the frame to under 250 g if you want to stay on the lighter side, but don’t skimp on the carbon or aluminum; they’ll take the hits better than plastic. For endurance, a 4‑cell Li‑Po gives you a sweet spot: about 25 kWh per cell, but remember that the ESC and motors will chew up a lot of that under load. Pick a brushless motor with a 10:1 torque ratio; it’ll survive a decent hop but still be agile. Stunt mode is where you need to balance power and stability. A 2‑axis gimbal won’t do, you’ll want at least a 3‑axis stabiliser so the frame doesn’t just tumble when you push the throttle. Add a small shock‑absorbing suspension in the landing gear—think a tiny rubber ring or a mini leaf spring—and you’ll spread the impact. Test the whole rig on a soft surface first; a few low‑height jumps will reveal any weak points. If the drone is dropping or tilting too much, tighten the frame and add a bit more counterweight at the tail. Once you’re happy with the baseline, you can tweak the jump height. Just remember: every extra pound slows you down, so keep the battery light but big enough for the endurance you need. Happy building!

Nice pick with the HS170H V2 – it’s light, it has a decent motor‑to‑weight ratio, and the 3S LiPo gives you a bit of jump power without a lot of extra weight. Just watch the battery capacity; a single 3S cell at 2600 mAh will burn through fast if you’re doing aggressive jumps. The HobbyKing kit gives you more freedom, but keep the prop count to four and stay under 250 g if you want that endurance. A 10‑amp ESC is fine for a 3S system, but double‑check that the motors are rated for that current. If you can swap to a higher‑torque motor, you’ll get more lift for a harder hop. In both cases, mount a small shock‑absorbing suspension on each landing gear. A rubber bungee or a tiny leaf spring will spread the impact and protect the frame. Test the whole thing on grass or a padded surface first, and don’t forget to adjust the throttle curve so you’re not just blasting straight up and crashing back down. With those tweaks, you’ll have a budget‑friendly off‑road drone that can survive a few jumps.

Glad to hear you’re on board. Keep an eye on the motor’s current draw, log the numbers, and if it spikes above the ESC rating you’ll need a beefier board or a larger battery. Once the hop test shows a smooth landing, you’ll be ready for real trails. Good luck and enjoy the flight!
