You are quite correct- I ran into a bench testing my TXT-1 a few years back, and it snapped the output shaft on the servo (Hitec model with Karbonite gears). I think the main reason is because a servo saver has too much 'give', even a really beefy one, and crawlers want the most steering power they can get, so they just run a normal servo horn (alloy or plastic).
