Hi Lee   No, I don't have any experience in checking the side thrust in flight..Is there some special procedure to do it? I am happy to hear any hints..   thanks mate @import url(http://www.modelflying.co.uk/CuteEditor_Files/Style/SyntaxHighlighter.css);@import url(/CuteEditor_Files/public_forums.css);

Posted by Lee Smalley on 03/08/2011 16:09:13: Hi Artto, firstly i ignore the fixing locations as suggested by the kit, i mark the centerline of the firewall vertically and horizontally, then i mount the engine on the mount making sure the prop driver is the prescribed distance from the firewall, then i (with the cowling roughly fitted line up the engine with the centerlines marked and the center of the cowl exit, its a tough thing to get right first time!! Hi Lee,   Thanks for the hint I guess I can act accordingly next time. In this case it's too late, I'm afraid. I used the kit instructions and drilled the bolt holes accordingly, etc.   So maybe all I can do is add a tiny amount of side thrust to help the prop exit more centrally and rotate the cowling just a little, if necessary.   artto

Get a quiet day with no one around and just racy around do dummy take of runs with much lower power, up and down the strip and do it continuously for a full tank, this will get you really used to the rudder effect and how the model reacts on the ground practice just squeezing the rudder to hold a straight line down the strip, as for engine alignment if you are putting some right thrust in the engine then you have to offset the engine to the left on the firewall so that the prop exits centrally I fitted mine with no additional side thrust and had no problems Hi Lee,   Thanks for your reply so in your model the prop exits centrally without any modifications when using the original engine mounts? This is confusing as this is what I'm doing yet the prop doesn't exit centrally...   Or, did you twist or turn the cowling to make the prop exit centrally? (sorry if this sounds insisting just want to make it clear for myself..)   artto      

Lee and Stephen,     How did the cowling fitted in your models? In my case the engine sits to the right off centre in the extent the spinner won't sit in the centre of the cowling either?? Did you encountered the same? If yes, what was your solution?     thanks in advance, artto

I think there plenty of us who want to read more on how your 2nd Zlin flies..btw did your first Zlin pull left only at the take of or in the air as well?   I hope you'll have your "quality time" and manage to go flying..    

Thanks Stephen,   Thank you for your comment. I think I will add some side thurst, too. I'm sorry to hear about your lost of the Wot 4 and other circumstances that haven't allowed you go flying..   artto Edited By Artto Ilmanen on 30/07/2011 05:45:50

Hello all,   It seems the engine sits to the right off centre,when looking from the front? (Saito 125) Anyone else having noticed the same? Maybe added side thrust is needed..I don't know.   Any hints? / suggestions?   rgds artto

Anyone using a Saito or Laser engine?   rgds Artto
