Motor took a dump today 10 minutes into the flight. Just lost power and quit. On the ground no compression and clicking noise. Will prob need a new ring and liner I would imagine. This is the second motor that's had a big problem. 1st one lost the c clip off the piston rod, that didn't go well.
So if I send it out there, they don't have any pistons, if it would need that who knows how long it would take. I suppose if I tear it apart myself to find out what exactly is wrong they'll void the warranty, who knows if they'll warranty it anyways. I've seen others who had this problem and they didn't end up happy. Something about warped liners.
I could just tear it down myself and order the parts straight from japan for half the cost of hobbico and put a bowman ring in it.
I've been wanting to try a DA35.
Geez, sorry to hear of your problems. I'm almost embarrassed to say how much flying my number 1 engine has delivered. Still strong in it's 5th season. I don't think I'm doing anything unusual. I use MC1 Racing Synthetic from Bel Ray at 50:1 mixed in avgas. My needles are 1 1/4 LS and 1 5/8, actually a hair less, on HS. It's turning the 20.5 x10 PN at over 7K. Terrific idle.
I've paid lots of attention to cooling both the engine (notice the shrouds that suck air out) and pipe (note the NACA inlet just aft of the chin cowl). Here's a couple pics
