RE: Ryobi tuning help
Jim, it sounds good that you got your Ryobi running good. If you can find a metal shielded cap for plug and use some metal braid over the spark plug wire...that may be worth doing to avoid interference. Just a Idea. I have seen those caps on smaller imports at junk yards. The braid you can get off CO-AX. Capt,n;)

RE: Ryobi tuning help
Picked up a couple of resistor plugs at our local auto parts store. So ready to fly now. However, planning on going to the B-17 fly-in at Bomber Field this weekend. Apparantly Ike did not cancel the show.

RE: Ryobi tuning help
Ok, finally got to put the Ryobi in the air yesterday. On my 14 lb Sig 4 star 120, it flew the model flawlessly for 5 completely satisfying flights. Plenty of power on the APC 17x10. Would probably be better with a 18x8 but not enough prop clearance. She started easier than my Zenoah G20 and the XYZ ignition performed perfectly. A very fulfilling day at the flying field. Nice after all the heck I had getting it done. Especially since most of it was from my own ignorance. Well that is how we learn and advance in this wonderful hobby.
I was surprised at how much power it had. At full throttle and level flight I could ease her straight up and could go a long way before she ran out of oomph. Outside loops were a breeze and inside loops could be done easily at half throttle. Only problem I had was slowing it down enough to land. Even at idle, that 17x10 prop was pulling pretty hard. It would sit still in the grass but once on the asphalt she wanted to go. It turned out to be a great conversion. How do you guys feel about this engine on a 15 lb 90" Ryan STA? Would it have enough power for it? Jim |
RE: Ryobi tuning help
I would say it would probably fly it fine. Not unlimited aerobatics, but I don't think it would be a dog either. 18 x 8 prop, and I recommend APC.
