Installed a RACE5 in my DR107 'One Design' aircraft that I imported from the USA. Works really well - it turns a 360 cubic inch Lycoming easily. I get plenty of starts out of it and the planes alternator charges it at up to 8A. The battery barely loses any charge if I don't fly the plane for weeks on end - I only connect the Lithiumax tender charger on occasion to top it up.
Very happy with the unit. I did buy the Lithiumax mounting frame but my engineer had concerns about how strong it would be under violent aerobatics. Some additional bracing has been welded onto it, don't have any photos of it yet but.
