Hi Guys,
I just got my Wren 44 heli turbine, obvious choice is the Trex 700.
Does anybody commercially make the turbine conversion parts for the Trex 700 ?
What are the parts that need to change in the standard Trex ?

Xantos: congratulations on your acquisition of Wren 44.
I am waiting for mine & just informed that mine is ready to ship.
Once I receive my Wren 44, I will keep you posted with what I do.
I plan to install Wren 44 on Trex 700N: make it as a Wren 700T

I belive that you need to cut the front carbon frames and use spacers between the frames and the strengthener plates to provide clearance for the main body of the turbine. You then need to provide a strap made from ali or stainless steel to support the turbine where it meets the radio tray.
I think the Trex is a great candidate for the conversion. I have just finished fitting this turbine in my Synergy, and it is not the easiest.

this has been covered extensively on other forums,
a quick search on google should throw something up.
also I have seen a commercially available kit somewhere online.

I just modified my own. its not difficult

Are the stock ones not strong enough?

The stock skid might be strong enough.

I just do not want to have any risk if it breaks.

I guarantee that mine is much stronger & safer.

Isn't it about time that a major manufacturer made a kit to fit the 44 engine,instead of the amateur having to do it himself.I'm surprised the Chinese haven't done it by now.
