I like 'em "BIG"!
I wouldn't think of stopping you Mark. You need to get that plane back in the air. Hopefully your weather is better than ours. According to forcasts....we won't get a break until next Friday and Saturday.

We will get a beeak starting Monday but, it will take a few days for the field to dry out. That is ok because the engine won't be here until Tuesday and hopefully the new DS-14 will be here by Wednesday. The rx's and Central Box 200 will be here by Wednesday 
Then it will be a matter of learning a new tx and getting the plane back in the air.

Ok. Just downloaded the data from my Eagletree recorder and for those who are still in doubt that baffling helps and that good baffling helps even more, Details don't lie I only finished one side of the baffling last night because I didn't know the engine was going to show up today, 3 days early So, I put the engine on the plane and fired it up tonight to see how it was going to run and it ran great! When I pulled the data from the recorder I was amazed at the difference in temperatures between the two cylinders. I am going to finish the baffling before I run it again and I figure that the temps should be very close to dead even. Temp B in the graph is the right cylinder from this perspective, Temp A is the left. The temps went up at the end because I ran it up hard and then chopped the throttle and killed the ignition. It took about 30 seconds or so for me to get around to turning off the receivers. You can see how fast the temps rise once the engine is shut off. The interesting part is that the well baffled side stayed cooler during this time period then the partially baffled side. I figured it would have been the opposite.

Looking for some help reading these plugs. My thoughts are a touch lean. This was from a full throttle runup and ignition kill. The lighter one is from the cooler side of the engine, see previous post on baffling
I am running 40:1 Redline with 91 octane ethonal free gas.

So I was starting to get things ready last night to go to the field. Was looking forward to taking the super sportster as a buddy was bringing s radar gun to see how quick it is. Last time I flew it it kicked the prop. I just figured no big deal just put it back on right. Nope went to put it back on last night and something just didn't feel right. Busted connecting rod. Not sure how it happened as the motor was running good and if anything was a touch on the rich side as it was leaving a nice smoke trail. Oh well will see if I can get parts for it and go from there.
