] thought i had added this photo in 1st post.?axle forward or back.sorry see photo section cant get axle forward photo to load

Asuming your sitting as far back into the seat as you can sit (ie: with your back at a similar angle to the 'seat' back) I'd venture a guess and say have the axle about 4 inches (100mm) to the rear from the forward position picture. You want your body's centre of gravity (about your belly button,give or take ) just in front of the axle, preferably in the same plane as the crafts centre of gravity I think. This way pilot weight doesn't change the dynamics of the craft other than making it heavier of lighter (thats a simple model but I think it makes sense

Are those normal bike wheels on the rear?

wheels are a heavy duty bike wheel,ally rims, twice as many spokes as normal,13 mm axles.plan to use a 4.8 sail with wishbone [boom],may end up doing a number on it ,reduce luff curve and more conventional boom.

They are comfortable aren't they. I think I'll use one for my next seat too!

As someone has said before (Landyacht I think) lay on a plank thats sitting over a round tube (see-saw style) and roll either way until you find your centre of gravity, or guestimate it. Place your CG over, or in front of (but not behind!!), the crafts CG position (anyone correct me if Im wrong ).

The seat looks good, hope you get some more good build time in when your next at.

back to work [project] tomorrow ,just wondering about building in some ajustment for different heigth pilots,is this best done by slideing seet or ajustment built into foot steering

feet in position on foot pegs, seet in position[sorry landyatch i dont want to sit up,did try,but this is a very comfy position]?axle is up against back of seat,?mast about here i think ,maybe a smidge higher.i will post another photo re mast rake?think it looks better in this pic.just off of night shift so no construction today,i await your comments and input. regards steve

axle forward about 300mm it is,how about mast position and influence re photos ?forward ,back,rake

WHILE IM AT IT THIS WAS BEFORE THE AXLE MODS 'LANDYATCH'[HAD SKATE BOARD TRUCKS WITH STEEL AXLES CLAMPED TO THEM AND ALLY BUSTED]

thanks for the feedback,is that rear axle width,and please explain 'sideguards',pulley whip?out or up,both? i was curious to see if anyone picked up on the sturt peas in the background,i've been going to take acouple of photos for the general section. my first ever atempt at growing them.[grandpa would be proud]

just been out in shed to look at another sail option,been prof. cut down to i reckon about 3.5 take a pic tomorrow and post maybe even rig it up for a look.

Not sure if your extension extension is overkill but if you think thats bad check out my OVERKILL whip (I was calling it the 'tail' before this thread)
