Thread: OS 55AX Engine - crankshaft end float
28/09/2014 23:00:51

I have an OS 55AX which has survived a nose dive crash in a Blackhorse Renegade and am near to completing the repairs to the airframe.

The engine has been cleaned out, and turns okay by hand but I have noticed about 1mm of play when I pull and push the prop shaft forward-backward (no sideways movement). Does anyone know if these engines have this amount of end float as I can't remember what it was like before the crash which was several months ago?

Cheers, Graham

Worth pointing out. You'd think they'd change the writing on the boxes or at least put a sticker over that part if they've got a few hundred to get through.

Magpie. They're black and at least they fly too.

Thanks for that explanation Jon.

Thread: What did you learn with?
21/09/2014 20:18:35

Old Cosmo King 60" trainer from my brother's loft - with a "Friday" SC 46 2 stroke which kept cutting out! Passed A test on this, but had a few electrics to fly at the same time.


My 10 year old son is learning on a Black Horse Liberty EP, which is excellent - very gentle stall. He'll be doing the A test soon I hope. This really is a good electric trainer, if you want to avoid smokies.

I don't feel so bad about not buying those expensive things now - re-used biscuit tin cost nothing.

Pietenpol Aircamper - parasol wing is a bit unusual, but would be okay as a trainer and there's plenty of different full size paint jobs to copy for the scale enthusiasts.

I would go for the saito 45 on a 13x5 turnigy type A wooden prop (it must be the type A),


Jon - why the type A? I have been using type C on a puppeteer - should I change?

I really like your idea of using the scale side exhaust Flyeruk, I think I'll try that if I do another SE5a. Bet it sounds great on a Saito!

You can report them on the online "Action Fraud" website, if you can be bothered. Never click on any attached "invoices" either!

I think it means 6 turns of wire on the armatures - this effects the kv rating.

Thread: servo/aileron movement

One possibility is that your receiver voltage is very low causing glitching when the elevator servo is working and drawing current. I may be that the elevator linkage is sticking and forcing a high current drain, momentarily causing the receiver voltage to drop thus effecting the rudder servo. I would check that the elevator linkage is free, (disconnect it and let the elevator servo run freely) and check the receiver battery is charged.

Then if it still happens let us know and with the expertise on the forum someone should able to help.

Apologies - just re-read your post and I see you are using a speed controller and thus have a regulated power supply to the receiver. It is getting late! Could still be a sticking elevator linkage though causing a voltage drop at the receiver.

Thanks Danny, very good.

Thanks for your reply re exhaust Phil. I may end up doing the same on a cirrus moth in the future.

Thread: Sealing iron
07/09/2014 02:33:51

That sounds a really good idea. The iron I use is also losing its coating so I await your findings!

I have never noticed a lipo getting hot while charging. I think you were right to stop charging. I would not trust the pack. If it was just one cell that was bad, I would discharge the pack, open it up and remove the duff cell to make a 3 cell pack for another application..

Thanks Dave, I think that was the one I saw - it was about a year ago. I remember it being from the East. Thank you Cymaz.

I has searched on th'web but only found a rather small kit somewhere abroad, but does any one know of a plan for a Cessna Grand Caravan, perhaps about 60 inch wingspan?

I am interested in building one with the colours of Blue Sky Aviation (operates in Mongolia). This plane was used to save my wife's life in a medical emergency airlift while we were working out there some years ago.

If you still have the sock that came with it you could use that. As long as you keep it clean though (cleaning with white spirit when warm - not too hot! or alcohol when cold) it shouldn't stick.

I really like your exhaust work Phil. How did you attach it to the SC exhaust? I've seen your pic on the first page, but can't quite make out what you did.
