I've been reading around several forums and, as always, the really good guidance and alternative points of view far outweighs the bad. But there has been some stuff that concerns me on this subject. I'll save my other current rants about cramming as many watts of power into a small parkflyer airframe so it goes 120 mph -- I particularly got a kick out of the guy with a Corsair that was doing the scale equivalent of 1500 mph -- for another day. Today, I wanted to pass along some GREAT information on twins. I have found it to be very beneficial.

I've come across recent posts advocating stuff like using a separate channel for each motor on an e-power set-up for "true twin control;" others saying that using two different speed controls from two different manufacturers at different amp ratings really is no issue; arguing you can still maintain a twin model in flight just fine on one motor if one has ESC cut-off -- yeah if you know how to fly on only rudder and to only turn into the running motor. Ugh. And, one that I often personally struggle with -- balacing the ease of installing separate batteries in each nacelle rather than sourcing from one battery or parallel set in the fuselage providing energy to both motors. So, I wanted to pass along this piece below from Joe Ford at Castle Creations(joeford@castlecreations.com) who essentially relates the wisdom of the big boss, Patrick. It's a good quick read...

More photos than words here. I'm happy to report that my beloved Hornet from www.warbirdkits.com is back among the living. If I had to choose one favorite plane, this would probably be it. It's just spectacular in the air and a joy to fly. Through its many years, the original 3S 2200 Polyquest li-ion (first generation -- red wrap) had been trusty and dependable. On this day it reached its limit. In the back of my mind I knew the battery should be replaced -- too bad I failed to act.

Following a great flight and perfect landing, I noticed some slight whiffs of smoke where the fuse meets the wing. I picked it up and headed to the pits at a fast pace hoping is was a speed-control issue, but fearing it was the battery. Half way there all broke loose with a sound like a bottle rocket taking off -- and -- let's just say I haven't run that fast in years. The battery erupted. We threw caution to the wind, took off the wing and yanked out the burning LiPo pieces with a big hemostat (the wind was blowing quite hard, so nobody took any smoke). Thanks to the crew at New Canaan R/C club for helping -- especially Bob Morrow.

The following photos show the crispy aftermath as well as highlights from the rebuild. I'm happy to report that the Hornet flew again this past Sunday 7/29.

With fresh firmware and refined settings in the CC25 controllers and a brand new Polyquest 2500 20C pack, it came to life like never before. Power is a pair of Mega 5-turn inrunners with 7x5...Continue Reading

They have to go. They were a blast to fly, but I just don't feel right bringing a hunk of painted foam board out to the field that "looks" like an airplane, but just isn't. The HellRaiser, 3D Tiburon and on and on -- farewell all. Hovering simply ain't for me. I don't begrudge anyone who want's to fly these, they just don't have a place in my fleet anymore.

Beyond the "flat" airplanes -- that ironically fly 3D and 4D --there's the whole GWS and other foam plane world. I'm not against ARF's, affordable airframes and the like, they're bringing new people to our wonderful hobby, but GWS has got to stand for: God's Worst Styrofoam. Lousy plane with an orange propeller. Is this the best we can do people? I think not.

I am a fan of the Alfa Models line. Well though-out, beautiful, and excellent flight performance. Flying Styro is another, particularly because they skew more to a "modeler" permitting one to go nuts with the detailing. They don't fly as well as the Alfa's and are less durable, but boy do they look nice in the air!

And as I continue to cave-in against the weight my own weak-ass thesis, the Easy Star and the like are an absolute godsend for new pilots. We're directing all the new guys in our club to buy these as trainers. They're having a blast and learning fast. Many more successes than with the typical trainer aircraft.

Okay, no foamies except Alfa, except FSK, except....

Give me some wood, some fiiberglass, some Silkspan (yes, he did just type that) and even some Monokote!

Just stirring up the pot on a quiet Thursday afternoon. Asbestos pants ready, flame on guys...
