Rich,Many thanks.Ive got that.Here Mark   Edited By Mark Wightman on 29/01/2021 18:39:42

Sorry,thought you meant right thrust line,in addition to the down thrust.Cheers.

Thanks Alan, I thought that might be the case,wasn't certain.With regard to the thrust offset,there isn't any on the plan,which I thought strange but I'll leave it like that because I'm putting in an electric motor but I'll see how it goes. Yes,scale plans up by 150%.I've made a few scale plans(by Brian Tailor) and they've gone well.My flying is so so but I have a very good test pilot.😀 Yes,a tricky project.I intend to test fly the model before the fuselage is planked fully to see if the thrust is ok.So I'll be me able to make any adjustments so the finished look is ok.I need to think about that for a bit.Manks thanks for the help.Any suggestions are welcome.Cheers. Mark

Hi A question on the motor downthrust again.Do you think this needs to go up when I scale up the plans by 50%ie the motor points down more.Cheers.Mark

Hi I can find a folding prop (I'm doing away with the undercarriage)with a 2"spinner which would give a good scale profile but I intend to scale up the plans by 50%.I can't find a 3" folding spinner.Any ideas?I looked at the idea of an EDF but that is too complex for me,I think.This is the first time I've gone electric.Cheers..Mark

Many thanks,that's so goods to know.Cheers Mark Edited By Mark Wightman on 19/01/2021 16:57:14

Thanks Martin, Interesting. Didn't mention,the designer is P Bosak and it was designed in the 80s .Used to be able to get the plan from RCM&E.I got mine from Sarik.You can get the pdf from aerofred.com (I'd 96226),free.Wingspan is 36".I did think it might down to aesthetics because outline looks just like a Harrier.Cheers Edited By Mark Wightman on 19/01/2021 15:40:57

Hi Guys I'm just about to start the Harrier,RC 1462.The motor suggested is .40.I intend to enlarge the model by 50% and install an electric motor. I've made a few models,some from plans,and none them suggest a Down thrust of 6 degrees.Any ideas?The incidence for the wing and tailplane is zero.I don't remember any of my other models having down thrust.Maybe because the wing is annedraal? Any suggestions would be welcome.Cheers.Mark
