Ordered flishrc cobra. Communication was great. Ordered larger batteries but they were the wrong size. Olly shipped the right batteries and gave a refund for the difference I paid. Couldn't ask for more. Thanks for the help with the order.

The seller knew I was after one and very kindly informed me when they came back into stock so now have a Flywing Bell 206. Fantastic bit of kit. Well worth the wait.

About this product
Precision 7075 Exhaust for PROMOTO-MX
This precision-machined 7075 aluminium exhaust pipe is a dedicated replacement for the PROMOTO-MX 1/4 motorcycle platform. The barrel and mounting faces are machined from 7075 aluminium and receive an anodised finish to improve wear resistance and corrosion protection under routine off-road model use.
The kit is supplied with the exhaust and the mounting fasteners to allow direct replacement on compatible 1/4-scale frames. It is intended for hobbyist maintenance and tuning tasks where exhaust geometry and robust fitment are required. Not for use on full-size vehicles.
Packing includes
- Exhaust pipe – 1pcs
- Grade 12.9 black round head screws 3×10 – 2pcs
- Set screws 3×6 – 1pcs
Original Name / Part No:

Compatible Models

Engineered for straightforward mounting and long-term wear resistance, this anodised 7075 replacement exhaust supports reliable fitment and chassis compatibility on LOSI PROMOTO-MX 1/4 models.
What machining standard is used?
The barrel and mounting faces are precision-machined from 7075 aluminium to ensure repeatable fit and surface finish for model-scale assemblies.
How does this part aid tuning work?
Stable exhaust geometry and durable mounting reduce variability in backpressure and alignment, making this a useful component when refining power delivery and sound at scale.
Are the supplied fasteners high grade?
The kit includes Grade 12.9 black round head screws 3×10 and a set screw 3×6 sized for direct mounting to the listed frames.
Where should I check fitment?
Verify clearance around frame mounts and nearby bodywork before final torqueing to ensure alignment and avoid interference with chassis components.
What are the material benefits?
7075 aluminium offers a high strength-to-weight ratio at model scale and, with an anodised finish, provides improved surface hardness and corrosion resistance compared with untreated alloys. Write Product Review Please sign in your account before you can write any review.
