Looking for recommendations for mechanic(s) in the Los Angeles area. Bought an RV-7 in NH and have thoroughly enjoyed it thus far, but could use some help practicing basic maintenance and soon doing some upgrades in both the short and long term. Upgrades include looking at flight controls (some higher longitudinal stick forces in flight, no binding), asymmetric tailwheel control forces, installing an avionics fan, troubleshooting an aux input, upgrading to GAMI injectors, etc. etc. Aircraft is kept at SNA.
