Liam, for a feather the best options are indeed either drillmotors or the 100 to 450 watt motor range from Technobots (such as the feather gold motor). For speed controller I would go for either a Scorpion XXL or a Sabretooth 25A.

Raptors have a different ruleset, they are not just 6kg feathers. Those weightclass robots should be referred to as Hobbyweights, not Raptors.
