I loaned both my X45 and 120 to Colin Straus for RCJI review. The 120 review was in June/July RCJI and Colin’s figures have all been very accurate.
My flight tests on the 120 show it to be conservative on fuel burn. It is a top class engine in all respects, power , size, weight, fuel economy
I have the latest 90 on order, expected in Jan, and that, too, will be loaned to Colin for tests and fuel figures will be in that review.
The 90 will be flight tested on my Paritech DG 303 .

Hi,
The X120 pumps fuel connections are too big for 4mm tubing, The turbine came with a piece of 6mm tuning, It pushes on the pump connector really easily and is not secure.
The turbine fuel line connector is for 4mm tubing.
I didn't think a 120 needed 6mm lines. (My P130 uses 4mm).
I am wondering how folks are piping this motor up.

Thank you Danneman!
I found the barbed connectors on my X120 pump to be larger than the ones on my X90 pump.
I needed to warm up the 4mm tubing to get it to go on. This made a very nice tight fit.
The 6mm line slipped on and was too loose. I could pull off with little effort. So, I used a short piece of 3/16" Tygon over the 6mm line as a clamp. This tightened the connection enough so I couldn't pull the line off.
I then used safety wire on both.

Its good you are using you use a wire tye approach to ensure a good seal and a pipe that can never slip off. It what I do on all barbed connections.
