Anyone going to the wram show this year.

[MENTION=443]ghoffman[/MENTION] and 2 others go with me every year. We do a day trip on Friday before the craziness of the weekend.

Any one got a eme70 if so how ya like it

I do. Have one in a 3dhs 91" Yak 55. Have 4 tanks of gas through it now. It's turning a Falcon 24x9 carbon at about 6600 rpm, and still increasing on that. I don't have any baffling on the Yak, and that is proving to be a problem as it got a bit hot and dead sticked on me last weekend, resulting in a snapped landing gear leg. No airplane damage fortunately though. So I'll be building some baffles and fixing the heat issue.
Otherwise, it's a bit early to tell too much. It likes an extra flip or two after it pops on the choke. And even then it might take choking again and repeating the process to get it to start. Though that seems to be getting better as the motor breaks in a bit. Pulls like a freight train though, Very strong. Smooth runup. So far I'm happy with the motor, but like I said, no idea how it will be after a lot more time is on the motor.

I was having some temps reaching 330°F with throttle management on the DA70 until I baffled it. Now temps are in the 230-285 range no throttle management needed. It's getting pretty hot to dead stick. Temp sensor proved handy to me.

Hmmm... don't know what the temps were on the back of my cylinders, but the front was 185 about 5 minutes after it landed from the dead stick. So I figure the front was 200-210 in the air, and back of the cylinder likely 275+. Doesn't sound like that temp is too much for you, but I was having extremely noticeable power issues, wouldn't spin up, and then died. I will be baffling it this week. Bought some foam today, and ordered the EF cowl insert from their 88" Yak. Hopefully I can make it work and not look too bad.

I used the foam canopy deck to make my baffles out of... I like to see the inside. Used EPP flexible glue to glue together and in place. I went to micheal's and grabbed some foam, but opted for the thinner stuff.

Looks really nice. Mine is made out of super thin ply and works really well.
