Rusty C

Yeah I do the motorcycles and cars also so have plenty " rubbish" about a she says. Probably go for the acro I think looks a good flying thing. The sc inverted would either idle great and run utter rubbish or run well and wouldn't idle for nothing. So I just gave up on the model, hopefully I will get the engine in the air soon as it done nothing but be run on the ground lol

Thanks guys I will decide between the zlin, isport and the acro wot soon and get assembling. The AT 6 was a bit of a let down after it went together well and generaly a good quality kit, I guess it would have been fine with a 2 stroke. I am just in the process of robbing the parts from the AT 6, is its just me or is it hard to put a model down? Feels weird taking them apart but the wife would go nuts if I have more than 4 planes

I did look at the acro David, how is the quality of the kit anyway? Cheers

I couldn't get it to idle for more than 20/30 seconds when it was performing correctly, it is/was fitted to a seagul AT-6 at a sort of 8 o'clock position, near the end of my and others teather we started to point the finger at the tank position. The bulkhead was always very dirty with fuel so siphoning was a problem. The engine is running beautifully on the test bed so would like to use it in something, it might just be fine at a horizontal orientation. Thanks for the in put lads

I like the look of that z50 Steve, I have a pulse xt 25 e that i really enjoy to fly so was wanting something along that lines. That should take the 70 upright ok I'd think. Cheers

hey guys can I get some ideas for a new airframe for an sc .70 four stroke. However the engine needs to be mounted upright as I have had heaps of greif trying to set up an inverted arrangement.

Hi chaps this is my first time back in a while, totally up to my eyes in work amongst other things! Just in need of some opinions today. I bought a new Irvine 40 ages ago with the intention of putting it in my first ic, in the shape of a trainer, however I came on leaps and bounds and now have a Texan with a 70 fs. I now have it looking at me screaming for a home and I can't think what to put it in. Anyone have any ideas? I fear it may be to small for anything worth talking about. Cheers

I used the 4s purely for the balance issue that the airframe has. rusty

Hey guys just wondering if anyone else had had any bother with Tjd before? My problem is that they are sending my orders out unfinished with notes on the invoice " xxxxx parts to follow" Now although I appreciate the swift order send out I would still like to see what I have paid for! I emailed them a week ago with no response so looks like I will have to call them tommorrow. rusty

The Aileron control when activated raises one and drops the other. Is this the order of things in real life? Yes this is the norm it generates the roll, Up aileron for a downwards motion down for upwards . Of course they need to be the correct direction. I would recommend ditching the chase view asap as you will not gain the orientation skills required, There is a time for this view at the start to understand how the aircraft works but that all really. rusty

The SC is still in and is sorted it took a hell of a time sort out, I still had to give up a bit on transition in order to get a rock solid idle as it is a touch lean. But Its not a problem as its just a little wobble at a stick position that is not producing any meaningful flying power. I am still not 100% convinced with it but I dont think it warrants and new more expensive motor. The aircraft itself looks and flys lovely very forgiving with now bad habits yet! rusty

My tank centre is at fuel inlet level maybe very slightly lower, With this and the test for syphoning I should think all is well. When I was on the test bed I was playing about with the tank lifting it way up and there was not much to be noted really, So I am hopeful that this will end well. I am determined to get this F/S and AT-6 flying on Boxing day so here's hoping. rusty

Well guys I ended up taking the motor out of the AT-6 and back onto the test bed, After about 30 mins with a good warm up the motor is running to its best it will now idle till the cows come home! and even with an long idle snapping the throttle open the transition is great. I am really happy its running great as I was beginning to think I was losing it, I am no guru but I am not totally idiot as I have had engines in my blood since I can remember wether it was bikes,cars or rc cars. Anyway now that I can confirm that is a good un will tipping it slightly upside down effect it much, If so how? and why? rusty

Stuey The run in process with the full throttle and crazy rich setting I dont agree with, 2 and half turns is way plenty at a throttle position to suit a nice lowish rpm, couple of tanks at that then a half lean to start varying the rpm from idle to half. I belive that you want to heat it as quick as you can and a slobbering rich mix will not allow this. I know that car engines are of a different make up but, when I run them in I use wrist bands to cover the head, set the throttle to idle and use the low end to meter fuel, rich on start up then I lean and richen to maintain around 100 degrees on the head button, this way it reduces the bore tightness. Your could be right that it has just not done enough yet though, I may let it run at a fast idle for while more yet before turning screw again.

Steve When I was setting the tappets up I was doing it in such a way that the paper could be pulled out easily so I dont think they would be far enough out to cause any bother, But I will buy some gauges soon when I next get to halfords or the likes. The engine runs fine on the glow, when its removed it dies but not instantly it more a slow death. you can almost here the blood in its throat gurgling then thats it. This Is why I was worried about the orientation of the motor sounded like it was pooling up. As for the engine age I had it running for a long time on the bench 5 8oz tanks at idle which felt like an eternity. I dont think its a mile away now but its real frustrating as the final touches seem to be really sensitive. If it does not happen soon I will need to think about either getting a different 4 stroke or putting in a 2 stroke as I want to have it air worthy for boxing day! rusty
