7x4 APC Slowflyer Prop

purchased this for 3CH art tech wing dragon slow flyer as the parts for it seem to be scarce!!!
with a 2.3mm collet adapter and this propeller the airplane has much more thrust then stock by far as well as the propeller is more durable VERY satisfied with this product and recommend to anyone looking for a good replacement especially as to the fact i have no experience balancing propellers as i am somewhat new to the hobby this comes already balanced apparently!!! if ya need a good prop this is it
