RC BIKE FORUM

You asked. They delivered. RGBK-4R Superbike Double arm version The all-new RG BK4R 1:5 scale RC motorcycle has officially dropped — and it’s everything we hoped for, plus a few surprises we didn’t know we needed. Whether you're a diehard BKR pilot or just RC-curious, this thing is built to rip. So what’s new? Plenty — but not in a “let’s change it for the sake of it” kind of way. This is a proper evolution. All well refined and clever engineering mixed with the highest precision and quality parts that have always been standard with all RG products. RG BK-4R Clean. Smart. Fast. The Upgrades We’re Frothing Over: Better Chassis Layout: They’ve opened things up — more room to work, easier ESC install, and optional cross bracing so you can dial in your flex. Stiff for grip, loose for flow — take your pick. Added body support posts have been added into the front of the chassis to keep the fairing even more secure at high speeds.  Cooling + Receiver Box (Standard Now!): No more duct tape fixes. The new 3-piece system is clean, cool and easy to swap when you bin it at turn three. New three piece air duct and receiver box Front End, Update: A new floating axle and hub system tightens the front right up. No risk of fork bind or vague turns. Just grip, lean and go. Double Rear Swingarm (Optional, But Worth It): New driveline config means you can swap sides depending on track direction — plus extra lean angle and smoother load on the bearings. It looks unreal too. RG BK 4R Super slim double rear swingarm.  Fixed Front Brake Rotor: Goodbye floaty drag and noisy disc. Hello cleaner spin and mid-turn stability. (Trust us, you’ll feel it.)  NAI Fork System — Now Stock: What used to be a premium upgrade is now baked in. Ride quality is buttery out of the box. Build It Your Way  BK4R comes in Superbike or Stock Bike setup (Stock spec skips the front brake). Choose your weapon: • Single-sided swingarm = faster tyre changes • Double-sided swingarm = added stability + driveline options • Brake servo or no brake servo • RTR or kit — message us to sort your dream build Shoot us a message for more information or discuss RTR option here, info@holeshothobbies.com To order yours now head here

Having had some time to test and play with the new wheelie module, I thought it was a great time to share our thoughts, experiences and some help for those of you that would like to adjust and fine tune the module performance. The wheelie module can be used on other RC bikes other than the CRS 1:4 kit, however we have focused our testing with just the CRS Bike. I have had some good feedback from some of our other customers who have tried the module on 1:5 scale bikes and also had excellent performance and results with it. It is possible to program the PID values in the settings which control how the module behaves and performs for different driving styles and conditions. The module will operate with 2S and 3S packs, in our testing we noted that for the CRS the module works better on 3S with stock gearing and ESC settings. Running the module on 2S we found that both adjusting the PID values and also calibrating the module with the front wheel slightly inclined resulted in better performance and longer wheelies. Once you have installed and calibrated the module for the initial setup it is not necessary to calibrate each time you run the bike, however you do need to keep the bike still for a few seconds when you first turn it on, giving the module time to arm itself. Re calibration is only required if you change the install location or position of the module or we have had a couple of instances where it required a reset (perhaps due to a big crash). Programing the module is done via the PC software and linking the module to pc via USB.
