But it's not a Losi engine, is it?..


pan bimbo, the Losi won't be longer. It just used to be the case that the Spin-start backplates were too big for Savage engine mounts. The new 454 as well as the Dynamite Big Red have combo Spin-start/pull-start backplates - and I don't know if they fit in a Savage automatically.. I would think the Big Red does.. The Losi probably does too.. Just back in the day there were issues getting Machs to fit...

I would still look seriously at the 454, since they can be had so cheap on ebay.. Maybe some Savage dudes in the know can confirm if it is a dirct fit..
