This is the Revolution Design Racing Products 1.5mm Ultra Wrench. Revolution Design Ultra Series wrenches feature a machined 7075 T6 handle that provides a great grip for your hand, while helping to reduce fatigue and eliminate the chance of blisters after hours of wrenching. The handle is black hard-anodized, with a laser etched RDRP logo.
The blue end cap indicates that its a metric measurement tip, and the size of the tip is marked with large letters on the cap and again on the tip for easy identification. But, the most important part of a good wrench is the tip. RDRP Ultra wrenches feature a high grade spring steel tip that will provide a long life and is precision ground for a tight fit on the fastener.
This one is wonderful !
It looks as good as you think it should look, feels great and is perfectly made.
hex tip is very well made, it fits into screws very tight (depends on screws of course).
On some screws you have to apply even small force to slide this wrench in and it results in 0 slop.
I have also brand new E-flite driver set and its 1.5 hex is smaller, even there is are screws, where E-flite would turn easy without gripping the screw !
This RDRP wrench take the same screw with slight slop (acceptable to my standards).
I am impressed :)
Design better than any of Hudy wrenches and probably the quality as well - replacement tips are priced fair by my standards.
Anyway if you have 450 heli, you will know that getting good 1.5mm hex is mandatory and this one does everything it is supposed to do !
P.S. you can place this wrench vertically on its flat back, very stable.
Also you can take its back cover off (secured by rubber ring) and place plenty or screws inside to prevent loosing them.
