Default Converting from tri gear to taildragger gear

Looks like FokkerAce will be the man to help me with getting my Deception completed.

I was thinking of eliminating the nose gear and converting it to a taildragger. I wish to use the wire mains in the kit, but how far forward should the gear be moved to make it a safe (not too easy to nose over) taildragger?

If I could see a couple pictures showing the location of your taildragger's wing mounted main landing gear position I would appreciate it. I know it has to be well in front of the CG.

Thanks for the help.

By the way, I decided to make this an SPA bird with an OS 91 Surpass II and fixed gear. I'll be moving to the Florida panhandle in 5 months and look forward to flying BPA (Troublemaker w/ Rossi .60 on a pipe and Tiger Tail 3 w/Rossi .67 on a pipe... both with retracts) and SPA (Deception w/ OS 91 4-Stroker).

Again, if anyone could post or PM me a picture or two showing the wing mounted wire landing gear for a taildragger vintage pattern plane I would appreciate it!

Thanks,
Dave

Certainly no further aft than the LE. Tail draggers are not as critical of wheel placement as trikes.

I wouldn`t do it if i was you.I had my deception as a taildragger at first but very quikly converted it to a trike.Lands nicer and easier as a taildragger it tipped over on every not perfect landing.

But ur choice

Do you think it's because of the longer nose moment?

Heresy!!

Actually, I don't think the longer nose moment alone would cause that problem.

I could use a picture of the bottom of someone's wing showing the tail dragger gear loaction. I would like to see how far forward I should move it.

Hello Dave:
I beleieve if you place the gear such that the front edgeof the wheel is inline vertically with the leading edge of the wing you should be ok. This should be well in front of the CG and have sufficient tail length to minimize nose-over unless the wheel is actually blocked by some foreign object. Thi has been my experience on Chaos, Killer Kaos, Summitt's and Dirty Birdy.

I had it a little further back maybe if you put it like you say it will work better.

I remember a rule of thumb relating to this. It was to draw a line from the center of gravity forward at a 30 degree angle. The point where the line intersects the ground is where the main wheel should contact the ground. Further forward, and the airplane will tend to be squirrely, further aft and it will be more prone to nose over. A quick observation of a selection of taildragger aircraft will show this to be a fairly common set-up.

Remember, this is a general rule. Your mileage may vary.
