  • Thanks for getting back F22. The reason I asked about your experience with the motor is that I was thinking of using the same motor in a 70" CMP FW-190. It has a big round cowl so I wanted a motor to run on 6S tha could run a larger prop. The E-flite spec for the 470KV power 60 say the recommended prop range is 15 x 8 - 17 x 7. I'd be very interested in what your combination is pull for amps/watts.

    • Heading to the field this morning to get a few flights on the Ryan as a warm up for the Fly I this weekend. Still have some more details to finish and probably won’t get them all done, but she should make a good showing.

        • Probably the worst video I have recorded but she is all trimmed and tuned. I will be flying her on Saturday.

            So into the wind and back again and still in one piece. Good for you Trainer!

Don’t know if you caught it on the video but I lost a few connections on the flying wires. She flat vibrated the fasteners off. So they all got a dose of blue Loctite while the cowl dried

ID:	188405 Ok, last picture before the event. I will get some with the other planes at the event. I am almost done - at least as far as I am willing to go. It would be so easy to get sucked into the smallest details with this kit. Sig gives you everything you need to go as far as u want. I don’t want to put so much work in it that I am afraid to fly it - I have reached that point. It’s time to fly this beauty. Tomorrow night will finish the last 2 detail items and get the car loaded. I hope I can find a way to haul the T-6 and/or the PT-17 - we will see. So these birds have to fit in the Civic...
                I know, right?
                But usually I can get 4 or 5 planes int it without disassembling them. And just to give y’all an idea how big this gal is...

                    • Looks great. Sold mine many years ago when running glow. Makes me want to build one again with electric power.

                        • Hey F22, I think your weathering looks great mate. But you know as well as I do, that if that were a real one, there wouldn't be any weathering what so ever. Maybe just a bit of oil residue that would be promptly wiped down once the owner landed it. LOL My uncle had a PT-22, it was always like a polished jewel. But you did do an excellent job mate.

                          Best Regards

ID:	188690 Well, I guess this could qualify as a fitting final photo for this build. However I will reserve that honor for the photos taken with me and the plane with the award. Out of all the beautiful planes that showed up I was stunned when my name was announced.

                                  • Thanks Woody, El Bee, Blues, Hardway, and everyone else for all the ‘Likes’, for all the encouragement along the way, and for watching the build. You guys are great.
                                    I met a goal and am grateful for the interest and feedback.
                                    :Cool:

We’re not comfortable with each other yet - you know how that goes. Only got one flight before the winds arrived, but suffice to say I did not break anything. Took a few good snapshots also. And, as an epilogue, The buyer of a kit I bid on eBay backed out after the auction ended. The seller opted to give me next shot at It t my bid which was trumped 3 seconds before the buzzer - I had waited until 15 seconds to throw down. Therefore, there is a brand new never started Sig Ryan STA On the way to me.
                                      I’m thinking of a potential re-kit of the bird...
                                      ARF’s seem to be quite popular.

ID:	193871 Been holding off on a few other details I wanted to add, so here’s a hint of what Callie is working on.
                                        I did get my scale-ish looking prop finished. May get her out on the flight line tomorrow.

                                        • Didn’t get any video, but for those wondering about the motor / prop combo - here’s something I didn’t expect. As you know I have been using 14 x 6, and went to a 14 x 8 after the maiden. Both were wood props and I did like the appearance and the performance was good. Battery life was super as they never got below 80% for a 6 minute flight. A scale prop would be about 16 inches in length, which is what I ordered from Master Airscrew to make a static display prop. I also ordered a few e-props and figured I would start with 16 x 8E. The seven minute flight - a delay on the runway caused me to stay up until clear and had to do a go around, left 46% battery and she trimmed out at 1/2 throttle nicely. She acts a bit tail heavy again - should have checked the prop weight difference. But it wasn’t a frightening surprise and trim was adequate to compensate, and it did help on landing - no chin scuff marks to touch up!
