Big,

Not sure if your question is real or just a troll and I expect you are not getting a response because what you are asking is like asking a 2M flyer how to put a nose gear on a 2M tail dragger aircraft. You would need to hack the wing sheeting off the gear area of the wing, add plywood wing rib doublers, gear blocks, re-sheet the wing and cover. You would need to do all this without damaging the integrity and strength of the wing. The other possibility would be to add swept back gear on the bottom of the fuselage in front of the wing or find a new wing kit. But rather than hacking into a valuable Kaos why not donate it to someone that really appreciates a classic pattern aircraft or the SPA ( http://www.seniorpattern.com/ ) and then buy yourself one of the zillion look-a-like tail draggers available in kit or ARF form.
