|Thread: OS 46 LA inverted, won't idle|
I believe the OS 46 LA manual reccommends that you turn the air bleed screw "...half a turn at a time...". Does that sound about right, or not?
I've taken the engine out and checked the backplate (which was OK) and the carb (which was secure, with both screws present). It's not the plug (tried several).
I'll look at the air bleed hole and the main needle over the next few days, if that doesn't work I'll try an OS type F. I have to say, though, that it looked more like a fuel issue than a plug problem...
Thanks for the suggestions, I'll fettle it over the weekend and probably try another run next week. BTW, tried 3 separate plugs without success.
It did subsequently occur to me that the carb air bleed hole might be blocked. Or maybe the needle is bent?
I have a second-hand OS 46 LA bought from a fellow club member, mounted inverted in a Great Planes Venus 40; starting is OK although it occasionally starts backwards when starting by hand. In its previous incarnation, it ran fine when mounted upright.
Full power looks OK (about 11,000 rpm on an 11 x 7) but the problem is that it just won't idle for any length of time, even when set quite fast (3-4,000 rpm). The idle is a bit erratic anyway and gradually gets slower over the course of about 20-30 seconds and then it stops. If the throttle is opened before it stops it hesitates and there's a lot of white smoke from the exhaust so it's clearly running far too rich, but no amount of fiddling with the carb air-bleed adjustment makes any difference at all. The fuel system is as per the kit (3 line set-up), and the tank won't fit any lower.
Something is clearly Not Quite Right, but I have no idea what it might be. Anyone got any ideas?
|Thread: Pick a plane 2008|
My top three of the top 12 on the shortlist:
1. Mosquito (preferably Mk XIII, with retracts).
2. Hurricane (with retracts).
NOT the Whirlwind. Sorry.

> Lots of people are asking for plans that are easily available for a few £, $ or €.Or even plans that have been published as RCME free plans within the last decade or so.
Personally, I think it's OK to vote for models that already exist; if a model is popular, it'll probably have been "done" many times. And the perfect plan has yet to be drawn...
My votes are:
1. Hawker Hunter (EDF) - maybe the two-seater to be a bit different (please use a proper airfoil so that it can also be flown off the slope)
2. Folland Gnat (EDF
3. Fairey Flycatcher (electric, maybe 3s/10 cells)
