Quick shipping, quick reply, great product!
Excellent product
Great replacement for stock propeller and better quality and performance.
Love these propellers, they are durable and of high quality. So glad I found Master Airscrew will not go anywhere else to fulfill my needs
Great product and fast shipping. Product came boxed and not in plain envelope which was important to prevent shipping damage. I would purchase again.
Great product,
Excellent quality propellers, fit and finish is outstanding. Very sturdy, great product!
Timber x upgrade no doubt
Durable, rugged, efficient, high quality replacement for any H-H E-f X1.2m Night Timber’s stock 13x4-2 prop. Must precision ream the stepped 1/4” x 5/16” prop hub to 0.3135” thru for the shaft adapter, and trim the spinner cone’s curved edges for proper fitment. This Full-Paddle Style prop gives a tad more thrust. Note: Upon a difficult wind-gust “landing”, I hit the dirt hard, bent the prop shaft adapter, but the prop survived in great shape. Recommended to replace the H-H E-f 13x4-2 factory prop that is currently unavailable.
This was the perfect replacement prop for my Night Timber X and Turbo Timber.
Perfectly balanced. My son loves the sound of his plane now.
Far superior over the stock Eflite propeller that came with the plane this is a very durable and sturdy propeller can take a few hard hits highly recommended
The propeller works great, fits and balanced
Those is great
Works well, is heavier than the original I Had, It is thicker and more resistant to nicks and hits on grass. I was expecting more speed/power because is heavier and larger but has much more moment and keeps turning longer after power cutoff. Provides good thrust and half throttle. Creates a nice good sound. Comes well factory balanced.
Great props, however it is required to ream the hub bore for my Timber X to mount. Not a big deal for anyone handy, but with perfectly balanced aircraft parts I’d prefer to not modify them. That being said, best props I’ve ever purchased.
Using this prop on the popular Night Timber X. The original props are currently unobtainium. Used Master Airscrew for years with my gas models so thought I would give one a whirl on this electric. Had to lightly ream for fit. Works very well. Draws a few less amps and has a bit less thrust. But this plane has plenty of excess thrust so a longer run time is nice. Recommend.
Ordered for timber x fly's great but to wide. By hub spinner won't fit.
The craftsmanship is excellent and the build quality is perfect, but the problem is it does not fit the aircraft. It came up as a result for a propeller that would fit a turbo timber, but not the right size, but that won’t stop me! I’ll drill it out and put these amazing props to the test! :)
