RE: engine out with controllability with spoilers or up aileron only.
I don't know anything about the P 61 but an engine out produces yaw, and yaw is controlled with rudder. Spoilers are for roll control and while they will produce a little yaw that is not what they are there for. I think the best way to handle engine outs in models is to be proficient in the use of the rudder. If you use spoiler only to control yaw in an engine out you will get a little yaw but a lot of roll, which is not what you'll need. However, it would be an interesting experiment. Paul

RE: Engine mounting angles, how to set up a twin
Thanks for posting that Ed, there is nothing like trying out ideas for yourself. I haven't tried offsetting the thrust angles but your efforts show that it does work. A while back my brother and I made a twin out of a .60 size trainer. We put two .25's on it and found the single engine handling to be very nice. The angles were zero-zero and we attribute the good handling to the small engines which, when one is out, doesn't create the wild swing we've seen on other twins with more power. I suppose it's all in the trade-offs we choose when building our models. We have flown many times to practice single engine flight and can do slow flight and even go arounds on one engine. I think this kind of practice will come in handy when we fly our scale twins. Paul

RE: Engine mounting angles, how to set up a twin
Denny, For a twin where the props are rotating opposite to each other you want the downward moving blade toward the inside; that is, closer to the airplane centerline. The reason is that the downward moving blade operates at a slightly higher angle of attack than the upward moving blade in high power/slow airspeed situations(takeoff). In that scenario if an engine quits there is less tendency for the airplane to move off heading than if the props were rotating the other way. Think of the prop arc pulling a little more on the downward moving side..... (if you want to know why send me a PM. don't want to ramble on too much here) I believe the effect in our models is small and there have been many quarrels on this topic in the modeling world. Not trying to start another here but the effect is real and can be demonstrated in the full size world. Look at photos of light twins on the market which use counter rotating props and you'll see that almost all have the props rotating the downward moving blade to the inside. There have been exceptions of course with the P-38 Lightning being the prime example. I have read that it was set up normally at first but they switched it around due to other airframe issues. For a twin where the props go the same way the prop arcs will not be balanced, so that, depending on which engine fails, it presents slightly different levels of performance; the one that causes the most decrease in performance when it fails is designated the "critical engine". I have built several twins and a four engine model and have set up all of them with zero offset. Don't know how much help canting them outward would be but if one quits you will have a difficult, but not impossible, model to fly. The best rule of thumb is decrease the power a bit in order to maintain control and find a place to land pronto. Putting larger, more powerful engines in a twin to cover an engine out is a recipe for disaster; extra power in an engine out situation is not your friend... Twin flying is great, best of luck on your project! Hope this helps. Paul, former multi-engine instructor

RE: Scale accessories with a lathe/mill?
Coco, It's a Seagull from the great Edgar Westbury. I think it was intended to be a marine engine and has water cooling jackets but should make a car engine too. It came as a casting kit with plans from Ebay. Stricky IC was a great mag; I was sorry to see it go, but there is another called Model Engine Builder which carries on and is very nice too. Your tether car looks nice, I did some work on a friend's a while back but only drilled and tapped the engine mounts. Your work is impressive! Gotta go back through the SIC issues and find your aticle. Paul

Bob, Not familiar with that ECU but most microcontrollers have something called a "watchdog timer" which is sort of an intrerrupt to keep the computer from locking up. Sounds like something is waiting for an input and timing out. Bet Bob Price would know! Paul

The prototype gear is progressing. I have more work to do on the top of the strut and to add the downlock parts. I think this setup will have enough authority to pull the big struts up.
