I than took a 40 size nitro front landing gear and placed a small piece of fuel tubing on the shaft of the of the new gear. I drilled the main guide to be slightly smaller than the fuel tub/shaft diameter.

I placed the fuel landing gear into the drilled out guide hole and than used some wheel locks to hold the gear in place from top to bottom. The reasoning behind the fuel tubing and drilling out the main landing gear guide was to make sure there was no room for play side to side.
I was wondering if you could send me a link to the landing gear you used. I have been trying to find one like you used but not sure if the ones I have seen are the size you used or not. I got this plane on black Friday and am in the process of doing the mods and getting it ready for spring. Thanks for your info you shared with us.

I was using a standard .40 size nitro landing gear. I am in the process of trying to figure out a new firewall, so I am probably going to be replacing the landing gear too. Something a little lighter as the new firewall is probably going to add some extra weight as well.

Anyone have any good idea's for what to build my new firewall out of? Plywood? another plastic? I don't have access to do a light aluminum plate, which I would prefer but, oh well. Wood is probably easiest to work with for me. I am just tired of trying to fix the plastic firewall and having my nose gear break on me all the time.

i did all the mods in this thread, and i did what 'Pono420 on page 9' for the fire wall and front gear, works like a treat had a few rough landings no probs so far...

Thanks skip sounds like mine is in much the same position as yours but underneath the cockpit and accessed by the original battery panel. I cut the foam away to allow the battery to move further forward into that same area. CG looks good and I am happy to test it when the weather improves here

Thanks BennettOZ84. I decided landings were too slow, thats why they improved at the end, I increased landing speed. Wind was definately a factor on these flights. The nose is also too heavy for this size ski which makes for rough slow landings. I'm in the process of making a larger ski for the nose to be tested. My 182 is next to get skis!

Hi everyone on this thread. I have been flying my 400 for a few months now.It is the HobbyKing.com version.
I have noticed a fluttering sound as the model flies by. I assume this is the elevators or the rudder. Inspection of the pushrods has revealed that have have become very flexible. So I have replaced them with3mm carbon fibre pushrods with 2mm piano wire on each end. Hopefully this will cure the problems.
