For 1/7-scale on-road builders who would rather run a body than paint one, Bittydesign has a new option: the Kanjo-N shell in pre-painted form. The new release fits the Arrma Infraction V2 and Felony, and it is also compatible with the Arrma Limitless. Bittydesign says the shell arrives exactly as it appears in the product photos, with paint applied and trimming already finished, so owners can skip the most labor-intensive part of body preparation.
What’s in the box
Pre-painted does not mean fully assembled. The box includes window masks, a pre-cut decal sheet, the decals themselves, front and rear aero flaps, a pre-cut rear wing, and widened wheel fenders. Screws for the wing are supplied, and the fenders use small M2 screws and nuts to attach. The front side aero flaps go on with double-sided tape.
Bittydesign says the trimming is done by robotic cutting, and that covers the shell plus every included part. The company’s pitch is that builders can set aside scissors and rotary tools and focus on assembly instead.
Dimensions and fitment
The pre-painted body is made from 1.5mm polycarbonate and has protective film on the outside. Length is 720mm, height is 174mm, and wheelbase is listed at 406mm with Arrma dBoots Hoons wheels. The two sources part ways on width: the announcement says 325mm, while Bittydesign’s Kanjo-N product page lists 306mm.
Fitment is built around the Infraction V2 chassis, with Felony compatibility noted in the release. Limitless installations require a few extra Arrma parts: the Infraction Body Post Mount Set (#ARA320517), Front Bumper Support (#ARA320521), Front Bumper (#ARA320515), and Outcast Body Post Set (#ARA320357). Bittydesign also lists the Traxxas XO-1 and Hobao Extreme VTE2 as compatible.
Styling and custom paint
Styling draws from Japanese car culture of the 1990s and 2000s; Bittydesign says the body was developed with Arrma in mind and positions the shell as a style icon for the 1/7-scale segment. The company says the design was aimed at fans of that era’s most iconic machines. The design phase took months of virtual modeling and rendering, and the final shell is produced with five-axis CNC milling. Wide fenders, front and rear aero flaps, and a large rear wing give the model a street-style, racing-inspired look.
The pre-painted release is not the only paint route for this shell. Bittydesign also offers on-demand airbrushing, saying it can handle everything from a one-color street-style finish to a more involved custom graphic. Options include pearlized and chameleon colors, artistic graphics, and racing liveries. A free painting quote can be requested by email, with a quote arriving within a few hours.
Retail context and price
Retailer Hobbies Direct, which stocks Bittydesign, identifies the company as an Italian brand whose catalogue pairs racing shells with custom-paint supplies. The retailer says the brand’s range includes unpainted bodies like the A3-F, Ahura GT, Destroyer 1/7, AR8-GT3, and Hyper-GT8, along with liquid mask, stencil sheets, and the Rock1 airbrush tool. Hobbies Direct says its Australian warehouse stocks roughly 34 Bittydesign lines, and local stock means buyers in Australia do not have to wait weeks for shipping from Europe. The store adds that the moulded shells have clean trim lines, which it says makes cutting and masking easier for first-time painters. It also notes that matching paint tools can be shipped together with a shell.
The pre-painted Kanjo-N is priced at €139, about $155, under part number #BDAR7-KJN-PP.
