The IRP Adjustable Downforce Bi Wing for the 5b.
We have worked very hard on this project for last few months and the end result is a functioning, adjustable downforce Bi Level Wing. The wing is constructed of 5052 Aluminum, all parts are cut on a Water Jet so all the edges are super smooth. Once the parts are cut they are then tumbled in a ceramic media to smooth the surface areas. All of the holes are then chamfered. The New Wing is 1/2 wider than the stock HPI plastic wing, the side boards are larger and longer for more side bite. The Upper plate, or Bi Level section, is adjustable from a 15 degree angle up to a 33 degree angle, and anywhere in between. This is accomplished by slotting the inside mount of the upper plate.
To adjust the wing simply loosen the bolts to set the desired degree angle and re-tighten the bolts. All of the hardware is stainless steel, consisting of 12 button head screws and nyloc nuts .
We were very conscious of the various pipes, and configurations , of them in the design so there will be no conflicts, basically if your pipe fits with HPI stock wing it should fit with our wing.
The wing has been thoroughly tested and design changes were made along the way, no wing is bullet proof , but this one is pretty tough.
We sent the wing out to Brian Schapiro to do some testing on some high speed runs, 65 + mph in the grass and dirt , and the wing did improve handling, both in straight away runs and through high speed cornering. Brian will also be putting the wing through its paces on his Twin Baja @ speeds well over 90 mph in his quest to break the 100 mph barrier. We are proud to be a part of his quest .
The Wing comes unassembled in a raw finish, if you want to paint it ,its ready to prime and paint. if you want to polish it, its ready for that as well.
