Next Shipping Day 3rd December

We are now in the process of moving Technobots 120 miles North to the Town of Rugby. You can still place orders on-line as normal but they will not be dispatched until after we re-open on the 3rd December

Machining Services

Our machine shop is also being re-located so we are unable to carry out machining modifications on gears, sprockets, pulleys etc. Any order placed which includes machining options is unlikely to be processed until mid December.

Hi, I have recently bought a speed controller from you (4qd vtx 12v 75a). Is it possable to use this speed controller from a reciever servo connection? If not can I return this controller and could you recomend a speed controller which enables me to do this? Thanks Shawn.

4QD controllers only accept a pot / voltage input with a switch input for reverse (where applicable).

However, they also manufacture an interface that plugs into the receiver and into the VTX. The part number is ( SMR-122 ) 3401-003 and are in stock at £25.06 each. We do not have an alternative to this solution for controllers of this rating.


Just a few of the companies Technobots are an official distributor for:
