I believe that it balances perfectly. Rctrax and I are just concerned that the main gear is almost right on the center of gravity. That would make it tend to nose over when taxiing on the ground. It would still fly fine, it just wouldn't taxi well and would tend to flip over on landing. Test it out by taxiing around some without taking off.

Amsterdamn,

Is the leading edge of your gear tapered and the back straight? It looks like it might be in the pics. If it is, you might try flippin gth egear around the other way. I've attached a pic form the plans I have. The dotted lines show the main gear for a taildragger Stick. You can also see where the CG is relative to the gear on the plans.

The plane looks nice by the way!

The nominal location for a tail dragger gear flying off of pavement is the axle under the leading edge of the MAC. On a Stick, this is under the leading edge. For grass flying, move it slightly forward.

Here's the dynamics. A tail dragger is unstable. The CG wants to lead the drag so a tail dragger always wants to swap ends. A nose gear plane which has the CG forward of the main gear is stable. The closer you have the CG to the main gear on a tail dragger, the more stable it is, but the easier it is to nose over. Put the gear forward and it doesn't nose over, but get a little out of sorts and that CG way back there wants to swing around and ground loop you. Locating the axle about 15 degrees forward of the CG is a good compromise for pavement.

Normally, your wheels are also straight forward or slightly toed inward. Don't over do the toe in or you'll cause nose over from wheel scuff drag. Naturally, they need to be free rolling as any drag is going to drive you nuts trying for a straight take off.

Each plane is different, but normally, you have to ease the power in so the plane won't nose over. On long fuselage planes, this is less of a necessity. The World Models Mach II has a fairly long fuselage and you can pop the power to it safely. A Stick has a medium short fuselage, so I would add power smoothly over a count of "one thousand." On a scale plane, you may need to hold up elevator to keep from nosing over.

In my opinion, the quicker you get the tail up, the better. The rudder tends to be less sensitive than the tail wheel in most cases and air flow tends to straighten the plane out.

Hi!, As it is the best option? tail dragger or tricicle landing? for the pilots aerobatics and hard surface for landing, no grass. Thanzs!

Huh? With a tricycle or tail dragger the CG is always between the wheels. Otherwise the model would tip up or down at rest.

Ground loops are caused by engine/prop torque and differences in lift of the wings (i.e. from a cross wind - upwind wing has more lift). Tailwheels have no correlation to ground looping. You just don't see nose gear on designs noted to ground looping, short coupled airframes like WWI biplanes, because there is no where to attach one.

I have a Big Stik 60. I couldn't fly it with the delivered covering scheme. I cut squares of red covering and put them over the white on the bottom of the wing. I didn't have the exact red but it's close enough and it makes the plane more flyable for me. It is a beast compared to a trainer or an Astro Hog.

The nose wheel is usually larger than a tail wheel, all else equal, and contributes drag. No other effect on aerobatic qualities.

But take a look at the big dog FAI & F3A pattern models and you will not see a nose wheel very often.
