Stock BG KerboProp Aircraft Speed Challenge!

Recommended Posts

Unfortunately 16 'S' type blades don't fit on the small turboshaft engine without serious clipping. Even with 12 blades there's a small amount of clipping and when I tried 12 on the Arrow it went slower.

So I went the other way and tried 6 blades per engine and saw the speed increase to more than 298m/s. This time best speed was achieved at low altitudes. Go figure.

Adding another eight engines made absolutely no difference to the top speed but for sheer amusement, it is the 24 engine "Barbwire Canoe" in the video below. It gets down to 4m above the water and it's a pity there's no ground effect in the game.

Speed run starts at 4:21 on the game clock. Speed 298.6m/s.

Alright. Another run at 301.7. No damage. No PRE. No runway-destroying.
Warning: music

No runway destroying because you didn't land on it :confused: Also, the speed record is the SLOWEST speed displayed during the 10 second run. I saw 301.5, please feel free to correct me if I'm wrong by providing timestamp of start/stop.

I have added you to the leaderboard, as it is an impressive craft and I believe you are "trying" to comply with the rules, but please make sure to read the fine print for any future entries, Thanks!

Super impressive! Appreciate your adherence to the "spirit" of the challenge. Are we approaching the theoretical maximum for LF power prop aircraft?

Alright 301.5. Sorry for not landing on the runway I didn't see that part.

I'm hoping not! I've deliberately stayed away from testing small designs and I'm hoping someone finds a way to go faster!
