I am building a plane and for the first time it requires thrust in different ways and I was just curious how you accomplish this. It is requiring 2 degrees right and 2 degrees down. How do you guage the 2 degrees. I understand that you can use washers but as far as the measurements and all. Is there a guage you buy or something..?? Thanks for any help with this. I usually buy my planes already built or the ones I have built have not required any thrust movement....

Dazzler,Robart makes an incident meter for about $30 comes with real good instructions on how to use it. Thats what I use

thanks alot..... I appreciate your help..

Truth be told, engine thrust offset is one of those refinements that many flyers blissfully ignore, and still have a good time flying their planes with reasonable control.

On the other hand, once you get to the point where you keep noticing your plane pulling off to the left all by itself when you climb from takeoff, and it starts to bother you, then you can fool around with right thrust. A washer or two under each of the left side mounting holes will fix it pretty good. Maybe a perfect fix would require 1.5 washers. I have spent a few minutes on occasion with cheap metal washers sorting them into thicker and thinner just for that purpose.

My lhs sells plastic wedgie shims, a little package with a 1 degree, 2 degree and three degree piece, so you can add them and get four, five or six degrees if you want that much, or stack them to get two degrees right and three degrees down, etc.

When you start flying competitive pattern, then you will want your ship to go straight all by itself under every condition, or turn just as much as you want but no more. You will find web pages explaining in considerable detail how you can spend flying session after flying session checking out your alignment in every axis, upright and inverted, taking your bird back to the shop for adjustment, then flying again to see if your latest adjustment threw off some of your earlier adjustments in some other axis.

It's wonderful to go crazy if that's what you want to do, but the first thing is to get out and have fun. Give it what looks like a little bit of right thrust and it'll probably fly just fine. Get a shop protractor from the hardware store for a few bucks to educate your eyeball.

thanks alot... for your reply... I will try that.. I just know it said some right and down... so I was also curious how you can give right and down... just put washers on the left side to give right and on top to give down.. ?

Yea washer's on the left and top... have you flown ever before or no?

Rasko,
Yes I have flown before... I own 12 planes. but the planes I own were either already built or did not require any offset of the motor for thrust.. Geesh, talk about insult ...LOL.. But thank you for the information...
