Does anyone else have light-up problems??

I find that my gas-start Wren in my Falcon is often a bit reluctant to start, but an identical engine in my Gripen lights on gas straight away. The only difference is the engine orientation.

Does anyone else with a gas-start engine in a Falcon have problems with light-up? and if so is the engine mounted with the plug accessible near the top?

Has anyone had to mount their turbine with the plug below the mount to get a reliable start?
My Gas start Wren has not really had any problems at all lighting off the gas while mounted to the airframe, other than the last 2-3 starts but I think I may have a blocked gas manifold problem..... but then again this won't be a problem for the Falcon 120 anymore because I just removed the wren 54 to install a K-80F!

Thanks

dave

Wrens are always fussy on gas the setting of the restrictor on the gas line makes a big difference to reliable starting

I have taken out the restrictor, along with the gas solenoid valve, in both these models.
I plug in the gas cannister through a non-return valve and turn on the gas manually after the engine's first spin-up.

The Wren in the Gripen always starts on the first whiff of gas, but the one in the Falcon is temperamental on light-up. Same can of gas, same day, etc.
I don't know whether to invert the engine, or change the plug or what.

Good to see someone building the Falcon 120 as it is designed to be. I have one sat in a box and would like to get on and build it so I for one would welcome comment.

Yes normally there are holes already in the wing behind the front bolt hole

Jetdeck, there is another thread somewhere that is dedicated to building the prop version of this plane, you may have better luck there.

Just to let you know that I'll soon have some Tornado V3 upgrade kits available which will fit the Falcon 120's. If any one is interested please PM me for further details. They are white gel coat so can be painted to suit any colour scheme.

Cheers

Ian

Just the job. I am looking to get either the Jetsmunt or Kingtech 80 or possibly hang on for the new Jetcat 80RX which is rumoured to be announced at Jetpower.
