    I have tried before but it does not let me delete them.

     

    it deletes when you edit but when you go back to the post after that .... they re-appear. I've tried it many times.

     

    cheers

    When you import the photos they all appear at the bottom. Each one has a cross in the top right corner which is used to delete. The last three photos were imported but not used in the text and by default are appended on the end.

    Not really, having a rigid length of clunk pipe is widely used, as explained elsewhere in this thread it prevents the clunk doubling back on itself and getting stuck (it’s happened to me!). In actual flight the clunk coming out of the fuel for short periods isn’t really an issue.

    Interesting Ron. Is there a set length for the rigid pipe and is it the same for all types of tanks?

    Re fuel tanks, clunks etc. An interesting bit of film from a decade ago. Took a while to find again but well worth a look. Maybe not what one expects to be happening.......

    Looks like a set up to me. There looks to be a section of solid white tube between two short sections of flexible fuel tube. Toto has the same but uses brass tube which means the result will be the same in that the clunk will come out of the fuel. What we need now is the same video but using flexible tube for the full length of the feed line, which as far as I am aware is the norm.

    Two strokes mounted upright, in this fashion, with the tank centre aligned with the centre of the mount (i.e. so the neck can easily poke through the firewall), usually mean the tank top is approx level with the needle valve. This has caused no problems for me. Upright and exposed also gives good access which is useful in a trainer. As for exhaust gunk, a few inches of silicon tube can direct the mess away from the airframe?

    Note OS instructions for FP series engine explicitly ask for the needle to be aligned only just below the tank top.

    Is the tank at the correct level, Top of tank middle of carb is correct, I have read that loads of times on here.

    I'm curious about some of the details of your model which I think have been modified from the original design - E.G. your model has an AMT but the OP one has elevators, it also looks like it has a ply-wood servo mount that's glued to the fus & of course the motor is an "enclosed" outrunner not a brushed one as I'd expect.      

    BTW is the motor fitted to a moulded plastic mount ?

    The ply servo tray looks to be original with a balsa block glued in as a battery locator. The motor has been replaced, for certain.
