You wrote: 1) "Assuming your empty weight is a portly 903 lbs and you are at max forward CG, you should have no more than 225 lbs on your nose gear." My empty weight is 972 pounds with 242 pounds on the nose landing gear. The empty weight CG is at 60.10 inches. The aircraft manual shows 61.50 inches as the forward operating CG limit. 2) "In general you should have from 10% (max aft CG) to 25% (max forward CG) on the nose gear." At empty weight I have 24.9 percent of the aircrafts total empty weight of 972 pounds on the nose gear with the CG at 60.10 inches, i.4 inches forward of the 61.50 operating CG limit. 3) "You really should move the main gear more forward." and "I would go with about 71 inches." I agree. How do you recommend that this should be accomplished?** I have already used a flox wedge to move the main landing forward to 72.25 inches. 4) "I don't think most of these parts were upgraded with version 3.X." I think that the Lyle #1 and #2 nose landing gear made for me were sturdy enough. Lyle beefed up the aluminum linkages when he made #3 for me. OC *PS: I have given some casual consideration to having Grove make a custom main landing gear for me that would move the axle locations forward, but have not pursued it.

Hi OC, In general you should have from 10% (max aft CG) to 25% (max forward CG) on the nose gear. Assuming your empty weight is a portly 903 lbs and you are at max forward CG, you should have no more than 225 lbs on your nose gear. My guess is even at full empty your CG is still not at the front limit. So you (like most every TR-1) still have too much weight on the nose gear. You really should move the main gear more forward. Based on 10% on the nose gear at max gross and max aft CG the main should be about 70.5 inches. I would go with about 71 inches. You really will like landing and taking off much more with this main gear location. Plus the loads and stress on the nose gear will be much less. Also keep in mind that when I checked the nose gear in 1999 (version 2.1, streamlined tube with added side plates) most everything did not meet FAR part 23 requirements. This includes the arms, pins and bolts along with the actual tube. I don't think most of these parts were upgraded with version 3.X.
