Clay,
Yes I have thought of the landing gear that Troy Built sells for the ESM war birds. I opted to go with the Hanger 9 150 P-47 retracts because I know Fishdeth used them and they work just fine off of a grass field. Let use know how the gear from Troy Built works on the Zero. I was not sure if they may have been long enough

If I do not like the way the Hanger 9 retracts work I'll give the Troy Built retracts a try if they work for you

I hope to get started on the Zero this weekend
