I put the fuel filler dot right in the middle of the red stripe of the cowl on the right side of the plane if your facing it. While I was breaking in the motor I just used a zip stripe and tied the fuel line to the motor mount. The remote igniter I just epoxied a small block of wood the the fire wall bottom left side and mounted it to it. "I didn't have the plug in type". I have a saito 100 in mine too and it was great. I used a big Groupner 4 stroke paddle which made the motor sound great and so much pull it was unreal, could fly on next to no throttle use very little fuel and fly forever. thought about switching to wood, but my saito ran so well on the groupner I decided to leave it alone. I had too big a prop so would only get 8700 RPMs. Was always going to switch it but flew and ran so well I decided to it alone.

A note on mounting the Cowl... The saito vibrates the hell out of the cowl and where the screws mount it will crack. So if you make the holes for the screws the size so the fuel tube just fits through, then cut a small O ring to fit in it, then slide the screw through it and tighten it. The fuel tube will expand and make a perfect buffer for the screw and it won't crack the cowl.

Everyone who I ever talked to always had to do some down trim after take off so expect to do it.

Couple picks of my plane and 1 on my other fav planes DR-1 just because I like it!!!

Good luck and let me know how it goes.
