“All batteries must be homologated by EFRA and must be in the EFRA list. 11.11 The brushless motor (Maximum of 2650kv - 2600kv) and speed controller combination must be or have been previously commercially available and have a maximum Euro recommended retail price (RRP) of 350 euro including all taxes. I think this is an unnecessary rule, max 1950 KV please, and price rule is bullshit”

If the max is 2600kv then 1900 should be ok as it is a lower rating ? Higher kv motors such as 2700 are not allowed. They is what my interpretation would be.
