That's not a mistake 
Doing surface scan missions can get samey, so I've built quite a few different ships just for the purpose, to mix things up a bit.
The Adder boosts to 560 which is second only to my iCourier - but with only a 2A power distributor it's quite a long time between boosts, even with a G5 engine-focused distributor.
The Clipper, meanwhile, 'only' boosts to 540m/s but, because it takes so long to slow down, I'm boosting again before it dips under 515 m/s. That's fast. Constantly fast.
So those bases never take long to appear under my landing gear. Although it takes me ten minutes to slow down and turn to find it again
