Let us take some of the stress out of holiday gift buying this season by giving you more time to qualify for price adjustments. Price adjustments on purchases are available 10/8/2022 until 12/25/22. If an item you buy has a price reduction before Christmas, we will credit the difference upon request, so you can shop confidently knowing your price is guaranteed.
All credits will be issued as Loyalty Club Points on your Tower Hobbies account.
RPM started by increasing the amount of material surrounding the hinge pins. They then ditched the offset button head screws that prevent the hinge pins from sliding out. Thier new in-line screws are a tried and true method of improving strength simply by eliminating extra holes in the a-arms. Fewer holes means fewer places for cracks to start.
The support beams on RPM's A-arms also gained some muscle. At their thickest, stock front a-arms are roughly 0.3” (7.62mm) thick. Rear a-arms are about 0.37” (9.4mm) at the thickest point, tapering down to 0.27” (6.86mm) at their thinnest. That amounts to a loss of nearly 30% of their thickness at the outer hinge pins! Not with RPM! RPM A-arms are a full 0.4” (10.16mm) thick over nearly their entire length! RPM only tapers them slightly at the hinge pins to match the maximum size allowable of the hinge pin bosses. Additionally, the width of the a-arm support beams are beefier as well.
All RPM A-arms are molded from our nearly indestructible blend of engineering grade nylons for performance you can trust.
