I had a bit of a chuckle on reading your post/question.
What you assume is that I know what a standard gear build looks like!
Noting that we planned the one-piece gear from the beginning of this build, I had to work backward through your question and then looked up thread http://www.vansairforce.com/communit...light=RV8+Gear
to gain a comparable handle on what you are asking.
The one piece gear was the obvious answer to our design. Firstly the weight is comparable. As I understand the numbers a builder can save between 11 to 17lbs (7.7kg) over stock landing gear using Grove options, so the added weight is only in the cross-centre section in our build.
Please have a look at the drop-test video http://www.groveaircraft.com/droptest.html
, and you will understand the need for center section clearance.
Thus, this answers you attachment question in part I think. So actually the attachment can only be made at the standard attachment points. However, those wonderful people at Grove also sent the Attachment Hardware along with the one-piece gear. I think we used larger AN bolts?
However, donít hold me to that just yet! Being in the middle of a flight pattern (BNE-LAX-JFK-LAX-BNE) I cannot confirm the above as I am floating around on your side of the Planet with only my Laptop. I am in LAX today, on my way to JFK tomorrow
There is an image below of a standard gear attachment and the RV8s attachment (note please the bolt hardware employed in this image is seconds and was for initial positioning of the equipment only- not what we applied in the final attachment of the undercarriage)
However, if time is of the essence (you need to know to order) to answer your question then give Shane Daly a call at Innovative Wings +1 403-247-8890. Shane is an amiable chap and as this part of the build was his focus (OK I admit conceptionally, engineering and aesthetic planning was done over several Rum and Cokes in the hangar kitchenette over several weeks!
). Shane will certainly be able to answer any detailed questions you may have on the Grove gear to assist you in your build in the short-term.
The rest of your post is entirely correct regarding the operational capability of the landing gear. Of course one should avoid potholes, running off pavement edges or excessive brake use as you describe and therein the outcomes that may prevail
