A great gift idea for your husband's anniversary would be a high-quality radio-controlled vehicle that he can customize and play with. You could research and find the latest and most advanced RC car models or the best brands for hobbyists.
Another idea could be to create an obstacle course or track within your backyard or local park and surprise him with a day of playing with his RC car. You could invite his friends and have a mini-race or competition. This could be a great way for him to break free from his routine and have fun with his hobby.
Lastly, you could also purchase merchandise or other accessories related to his passion for radio-controlled vehicles. Items like T-shirts, mugs, hats, or keychains with his favorite brand/logo can show your husband how much you support his interests and make him feel special on your anniversary.
Or you can get him a star map with the date of your anniversary.
