Absolutely true. To accommodate the Corsair's folding wings, its main landing gear had to retract rearward. The chord of the wing however was not wide enough to allow the necessary strut length to clear the huge Hamilton Standard prop. The solution was the F4U's signature inverted gull wing, effectively bringing the nose up without increasing the length of the main gear.
