I'm about to pull the trigger on one of these deals at ND.. It's between the Legend 25, the Legend 28, and the 28-8. The 28-8 I assume is the same as the 528XR. I had one of those back in the day, and it was a PIA to tune. That was in the relatively early days of nitro for me though. But even back then experienced people admitted that the RB 928 for ex. was a PIA to tune. So I'm not sure how much is objective, and how much subjective..

Anyhow, in theory anyway is there any difference in the way these three engines should tune? Is the carb on the 28-8 likely to be exactly the same as on the 528XR from 7-8 years ago? Thanks..

I'd also like to know if I'd be able to get a Losi Spinstart backplate on the 28-8, but realize here in the mostly racing section nobody will know that.. Although I realize bumpstart is better, it would be nice to have a Spinstart on whatever engine I get for running it in my DM-1, as I only have two startboxes, and the DM-1 has to share duty with my buggy, which is a (pretty big actually..) hassle...
