Great service at Altitude Hobbies

My first experience with the folks at Altitude Hobbies was a couple of years ago when I purchased a couple of Suppo airplane motors. The postage was reasonable and the delivery was quick. I also like using a Colorado based business since I live in the state. My last purchase was propellers and I forgot part of the order…I called to add another size prop to my order and they shipped it freight free…the guys and gals (I’m assuming there are gals too) run a business as it should be run…with great customer support. They will always be my first stop.

APC Props

APC props are the only ones I buy. I have never had an issue with balancing. If they need anything at all, it is minimal a best. They hold up very well during hard landings and prop strikes. I have never had one crack from extended use. The shaft adapters accept most of my motors with very few exceptions. Every once and a while, I have to slightly ream a hole to adapt to an odd shaft size. Very good props.
