SUPERSPRINT HARDWARE KIT by RCPrinter:https://rcprinter.com/products/m-jet-supersprint-v1-0-build-kits
Supersprint is 400mm long, resulting in scale 1/10. Designed for fun and ease of build, but at the same time the newest and brings all important M-Jet features developed over time. Has full documentation, build video and manual.
This file package contains:Original M-Jet Sprint&Supersprint
Supersprint is the newest update, which brings the most recent M-Jet features developed by M-Jet Development and the community into a brand new design, while keeping the style of the original M-Jet Sprint.
Note: This is not a physical product. After purchase, you can download computer files which you can use to manufacture your own parts on a 3D printer.Fully functional and complete RC boat model. All parts including the jet pump and pilots are included.
Supersprint includes:
STL files for all parts of the boat, including the pump, designed to be FDM 3D printed, mostly with no supports.
STEP file of the whole boat except for the pump (the pump is only included in the STL format).
You can 3D print it and assemble it with help of the manual, link above. You need to buy all electronics, screws and other necessary parts yourself - part list is in the manual, too.
Update log
Sprint 2021-12.03.2024 - update log was deleted because CGTrader did not allow description longer than 10000 characters.
Supersprint since 12.03.2024
Update 12.03.2024 Supersprint V0 was uploaded.
Update 14.03.2024 Supersprint V0.1: A quick small patch. An issue with too low wall thickness on hull middle in front left part of the lid interface was fixed - thanks San Xu for reporting this. An instruction about ESC placement was added into the manual.
Update 17.03.2024 Supersprint V0.2: Some more information was added into the manual, part list and the drawing. Length of the flat spot on the driveshaft in the motor coupler area was slightly decreased.
Update 20.03.2024 Supersprint V0.3: Slot for a third threaded insert for an option to adjust the ride plate was added onto the pump based on suggestion by Ryan Frair. 3 new ride plates with a hole for a third screw were added. The default tolerance on the main bearing in Hull rear was slightly decreased for a tighter fit. After a discussion with Justin Wombwell, a tolerance mod for tighter tolerances on both seals and both bearings was added into the MODS folder. Also, based on a feedback from Justin Wombwell, the TPU lid corner was extended for better grip. Tiny changes to file naming and part list were performed. Thanks everyone for your feedback!
Update 26.03.2024: Upon a request, a single piece hull STL was added into the hull folder. Furthermore, the motor KV chart was modified based on measurements of the Supersprint's pump. Maximum recommended KV for 3650 and 3660 motors was decreased. Recommendations of battery capacity were added. The STEP file was renamed to match the version V0.3 but there are no changes to it.
Update 21.04.2024: Supersprint V0.4: Optimisation of the pump is finished with the optimised impeller. Improved Lid_base geometry thanks to suggestion by Lenny B - thanks for your contribution!
Update 29.04.2024: A 3D printable watercooling jacket for 36xx motors designed and kindly shared by Lenny B was added into the MODS folder in Supersprint V0.4. Thanks for sharing!
Update 15.05.2024: A note about TPU Lid hardness was added into the Supersprint manual and Supersprint part list. The TPU hardness should not exceed 40D / 85A to generate proper seal of the lid.
Update 19.05.2024: A long bumper for the Sprint was added into the Mods_for_M-Jet_Sprint folder, front bumper.
Update 24.06.2024: Supersprint V1. 1) Supercharged V8 Engine with a moving butterfly valve, including a build video: https://youtu.be/LI-jd7MZr8I?si=lIpHHRi-onzhaG0s2) Printable tool for painting flames3) Drybox mini4) V0.4 to V1 conversion package to make the engine work with Supersprint V0.45) Multiple explanations added in the file folders, where questions were arising frequently. Some touches to the documentation. File organization. Some mods from you now in one place.
Update 09.07.2024: A single piece hull version was added into the Supersprint_V1 Hull folder.
Fix 11.07.2024: A mistake in the part list (both in the excel sheet and the manual) was showing a 3x53 engine slider shaft instead of 3x62 engine slider shaft. This is now corrected to 3x62 engine slider shaft, thanks Jordan for reporting the issue.
Update 21.07.2024 Thanks to a suggestion by James, a version of hull front joined together with hull middle has been added to the Supersprint V1 hull folder. This can be printed as a single piece without supports. Despite being possibly a bit unstable on the print plate, some people might prefer this and avoid one glued joint.
Update 05.08.2024 A modded servo mount with different geometry for a different servo by Dave was added into the Supersprint MODS folder. Thanks for sharing!
Update 12.08.2024 Upon a request, more nozzle options were added to the existing collection: +7, +12, +20. (I guess there is no reason for not adding more nozzles:) Furthermore, a modified Motor mount versions for different servos with altered shaft position were added into the Supersprint MODS folder.
Update 16.08.2024 A Jet Jam mod which uses the original Sprint pump scaled down to 75% created by Justin was added into the Sprint mods folder. Thanks for sharing!
Update 30.08.2024 The empirical equation in the Supersprint manual to calculate amp draw was updated to better match reality at very low KV and simplified to the most user friendly form.
Update 31.08.2024 Some nozzle versions were placed upside down. Thanks James for reporting this issue, it's now corrected. Description of ESC in part list was refined.
Update 01.09.2024 The steering shaft was found to have slightly incorrect dimensions. Drawing, part list, manual and STEP file were updated, the steering shaft should be 110mm long instead of 112mm (old).
Fix 03.10.2024 Based on a report, KV selection for 28xx motors was designed too high and could lead to damaging the motor. Recommended KV for 28xx motors was reduced in the manual. No other changes.
Fix 02.11.2024 Based on a report, the Steering and driveshaft jig by Kristian in the Supersprint mods folder was resized to fit the new version of Steering shaft. No other changes.
Update 30.11.2024 New information was added into the manual, print settings section. It solves an artifact on Hull front and Hull middle. The solution was found by James Tucker, thank you!
