Did a load of research on this. Found one side mount in the USA which the guy said was STC'd. Asked him for more details after he sent me a pic of a 44 flying with this thing bolted to it on the right side - never heard another thing other than he wanted $15,000 for the bag of bits.
Someone in the UK has been trying to get a mount strung across the inside of a 44 - which then slides out the right side for use. But too much vibration feedback to be successful.
A Tyler mount won't work on a 44 nose because there's no structure to bolt it to (unlike 206). The official R44 ENG has a strengthened nose section put in at production - and the battery moved down the tailcone to counterbalance the extra weight on the nose.
There is a 44 ENG coming into the UK soon with all the proper kit on it :
