Default OV-10 ground tracking with slightly off center nose gear

I would like to add landing gear spring struts to my Scale Tech OV-10. http://www.goldenskiesrc.com/SLG.html

I was thinking of just adding the nose gear strut to the existing fixed nose gear below the coil spring. This means that the nose gear will be offset to one side .

Will this slight off set affect the way the plane tracks on the ground during take off and landing?

Tks

Sportflyer in my opinion absolutely not.

I base that opinion on a lovely little twin that's a bit of a hotrod with OS 25Fx's that I built over ten years ago now that I set up to quickly transform from from a twin to a aerotow glider using quick release nacelles. It is still serving well and never had any sort of ground handling or steering problems.

Because I needed to have a reasonable location for the aerotow release and the nose wheel, I paired the release and the nose wheel right next to each other. The nosewheel is offset one inch to the side and that's a lot on a fuse that is four inchs at that point. Also I do not believe which side is a factor. I call the airplane the Oxy Moron which seemed appropriate for a twin engine glider

The Trident and the A10 also has off set nose gear .

OK. I will go with the off set because it saves a lot of effort .
The alternatives are a) replacing the coiled nose gear with a straight wire or b) Retain the spring gear but off setting the nylon gear mount .
a) is much easier to implement but I lose any spring action to absorb front impact on landing and thte straight wire will definitely bend with use.

Tks for your inputs

Can you eliminate the offset by spinning the current nose gear 180 degrees?

Yes indeed Sportflyer.

A new found friend friend from the jet community has operated a vary scale and very large A10 (well over 100inchs) for some years and off couse the offset nosewheel. Never heard of any related problems to the offset from him either. A very awesome airplane to watch.

Yes straight wire gear can be troublesome But for some missions I have actually had good luck where they are desirable such as some fixed gear racers and then on the other extreme I have done some warbirds that the only mission is arrested landings. For those two ships the retracts was deactivated and heavier wires with the coils was used as well as some other mods.

That just moves the offset from one side to the other.

I'm guessing that you are going with either a Y strut or a zero offset strut and not using an L shaped strut? Every nose landing gear I have seen has the normal spring toward the firewall, but the bottom is bent in an L shape thus negating the "offset" created by the spring. (EDIT: sorry, i typed this before looking at your link)

Why not replace the spring gear with a straight piece? You will have the dampening at the strut. Not as much travel as before, but dampening nonetheless.

And to answer your question, I've seen airplanes with offset nose gear perform well. I cannot tell you if it was the nose gear design or the skill of the pilot, but they did perform well.

I am going to try with offset . If it does not track straight I will replace spring nosed gear with a straight wire. Tks
