[Wots Wot - aileron linkage help]

I'm also having to cast my mind back years. I used cut down control horns - just 1 hole left - on the top of the bottom aileron at the trailing edge and bottom of the top one. I then linked them with 2mm Irvine pushrod sets.

[Anyone tried new Spektrum AR400 yet?]

I've got 4 of them & they all work as intended. Have flown to the limit of my eyesight in an Acrowot foam-e with no issues. Got them on offer stripped from sets & happy to pay the small premium over brightly coloured clones for the peace of mind they give.

[Hornet Moth G_ADND to visit Manchester 18th May]

The Air Navigation Order (ANO) Article 208 requires that, in the UK, specified flights
for the purpose of public transport or for the purpose of instruction in flying, take place
only at a licensed aerodrome or a Government aerodrome. The grant of an aerodrome
licence is governed by Articles 211 and 212. but outside of these purposes anyone can use an unlicenced airfield with the prior permission of the owner. I've flown dozens of times into umlicenced airfields and strips, accepting the risk of little or no fire cover and other facilities.

[OS 70 Ultimate FS]

I've got one which has run faultlessly for several years; it's presently in a Great Planes Reactor Bipe swinging an APC 13x7 running on Bekra 10%.

I bought it off a clubmate who could not get it to run properly.

All I would say is follow the instructions on pages 7-10 precisely. That includes the two fuel pipe lengths quoted. The manual can be downloaded via osengines.com if you don't have a copy. The engine does pump the tank up to a very high pressure so I use tie-wraps on good quality thick walled fuel tubing and have completely leak free plumbing - mine will keep the pressure for several days.

The only precaution I now take is before the first start of the day I remove the plug open the needle valve & throttle and spin the engine until the mixture can be seen venting from the plug hole. The pump seems to gum up very easily even with synthetic oils and needs a flush through with fresh fuel before each flying session. The action also pressurises the tank before starting.

Hope you get them sorted Paul, certainly if mine’s typical they can be operated reliably, I can’t recall ever having a dead stick with it since I set it up properly.
