Eventually....! got the Here GPS up and running on the experimental Solo. Wow. I have 3 solos. (1) Doner solo is on a Version A GPS (2) Playing solo MRO. (3) Experimental solo Here. In the back garden tonight all within 3 feet of each other. (1) Version A = 7 satellites and a hdop of 1.1 (2) Mro = 12 satellites and a hdop of 0.8 (3) Here = 18 satellites and a hdop of 0.3 So I swapped positions so they were in a like for like comparison. No difference. FYI the next door neighbour has a massssssive conifer in his back garden and I have trees and conifers also. The most I have ever seen in the back yard is 15 satellites and a hdop of 0.7 on the Mro. Obviously I have not flown in the back yard as far too much over hangs from the trees. So, I will fly them tomorrow evening if the weather is good on the farm and see which one is the steadiest and how good the RTL is in comparison. It's cool now I can create a flight plan then save it as a mission. I can do the same flight for each one giving a perfect comparison. A very happy Steve. I will post some pictures of the here on the experimental solo tomorrow. Fly safe everyone.
