There is 10mm between the firewall and the carb, it backs up tp the predrilled hole from the factory so there should be plenty of air flow. I am still looking at exhaust, I was first considering seeing if Kelvin at Keleo creations had a scale exhuast for DLE30 but after looking at the prices it was a little more than I wanted to spend so I will most likly go with a JTec Pitts wrap around. This way it will not disturb the cowl and the beautiful lines of this warbird will be kept. As far as the correct location of the prop..... I attached a picture of the gap, I ordered my spinner yesterday, with the backing plate there will be a little gap but tell me what you thinik, This is my first build. I think it will be OK it looks good to me but like I said This is my first. By the way I fly over in Kennedale right now at the Seven Towers RC club field. I have flown in grapevine a few times.
Thanks for any input.
