Rich too Posted February 1, 2014 Share Posted February 1, 2014 I just read that too. but John, don't they supply a template for DLE 30? I got the impression they do and that guy used the wrong template? I just noticed that you cannot change the angle of your motor with washers because it is too close to the cowl already - moving the engine up would help that..

Rich too Posted February 1, 2014 Share Posted February 1, 2014 this might be the answer - look at the angle of the spinner to cowl.... **LINK** check out post #12 "I installed it and set the cowl on the motor came out dead center like it shold but the cowl itself has way to much angle on the spinner ring. over 7* downthrust when run on the thrust line of the plane. irritates me but no one else really notice" reading that thread you've got nothing to worry about as you are, the guy said it flew great!

Rich too Posted February 1, 2014 Share Posted February 1, 2014 same thread, same issue! **LINK** I don't think you've anything to worry about, there is obviously an issue with the angle of the front of that cowl.

john melia 1 Posted February 1, 2014 Author Share Posted February 1, 2014 The surface which the cowl is sitting on is perfectly level Quote Link to comment Share on other sites More sharing options...
Biggles' Elder Brother - Moderator Posted February 1, 2014 Share Posted February 1, 2014 You can't measure relative to the base of the cowl - it doesn't mean anything John. You are assuming that the base of the cowl is a 90 degrees to the thrustline - there is absolutely no reason why that has to be so.

Rich too Posted February 1, 2014 Share Posted February 1, 2014 Indeed! At least they are consistent!! No BEB, I agree with you, it can't be measured accurately but the thread I found above reported the same issues as John. there is obviously some issues with the angle on the front of that cowl - others reported the same in the thread. and the cowl line should in theory be 90 degress or thereabouts Edited By Rich2 on 01/02/2014 16:27:55 Edited By Rich2 on 01/02/2014 16:30:55 Quote Link to comment Share on other sites More sharing options...
john melia 1 Posted February 1, 2014 Author Share Posted February 1, 2014 to be honest I dont think this problem is related to the engine box at all , after comparing photos from other sites and reading similar posts I think the problem lies with the cowl . with the fuse level as per martns diagram the engine while looking from the side with cowl off definately has downthrust , and while looking from the top , plan view , the engine definately has right side thrust .

Mark a Posted February 1, 2014 Share Posted February 1, 2014 Looks like the cowl is the problem, you may be able to fettle it so it sits a bit better in relation to the spinner. Edited By Mark a on 01/02/2014 18:18:15 Quote Link to comment Share on other sites More sharing options...
