As far as the low oil Laser fuel is concerned, there was some suggestion that older Laser engines should use the standard Laser fuel since they weren't engineered to cope with low oil. I have a 1986 Laser 75 which I will play safe with, the 150 I've had since the mid 90s I'm not sure about.

The club constitution should use words to the effect that legal liability is vested in the club membership as a whole, rather than making the committee take sole responsibility. All members must sign to abide by the constitution. I have seen rules to this effect in clubs concerning activities other than model flying. Lawyers, please feel free to comment.

Assuming you have assembled it as per instructions, it should be tightened as much as possible, failing that new fittings are available.

There were two versions of the 150. Earlier ones had a bronze liner and were nearly 2oz heaver than the later nikosil aluminium cylinder type.

RC Japan is the supplier of choice for glow plugs. I bought some OS 8s (provably genuine) which came in at £6 each delivered.

I cast a new canopy from an old one in plaster of paris by extending the old one from the outside with some more canopy material, then blocking up the ends and making a frame for it to sit in while the plaster was setting. I then mounted the master on a vacuum box and vac-formed a new one.

Airsail still appear to be operating from NewZealand although they call themselves JR Airsail, is this a different company. They also appear to be agents for Hangar One kits.

Mine had a Laser 150 up-front which was more than adequate. A 61 2stroke would fly it but it wouldn't do much more.

I recently invested in an X14 for glider flying, I was advised not to upgrade it beyond Ethos version 1.4.17EU because of some problems with v15.

Reports were that the Flyte 150 was simply awful and only lasted a few runs.

Another likely culprit is the chlorine somehow becoming dissociated from the PCV insulation.

I used some once but never again, the adhesive/colour layer stays sticky and it's doesn't hide the black surface of laser cut parts at all.

Having kept all my models in a centrally heated workshop over several decades, the problem never arises. I'm convinced it has something to do with moisture.

The tank is too low and just siphons the fuel back once there is no draw from the carb.
