Question
Chuck Cunninghams Lazy Ace

Does anyone know of a conversion thread (or even a build thread) of the Lazy Ace? I'd like to build one and convert it to electric but don't want to re-invent the wheel if someone else has already done it. I've done multiple searches here on RCG but no luck.
Thanks!

You didn't post what size? 96 inches, 77 inches or the 72 inches? As there seems to be at least two sizes via the internet and documented.

Here is the 72 inch wing span:

So sorry that not much help was realized via various Google Searches.

Remember this original 76 inch span plane was designed for a K&B .61. There is plenty of room for an electric of equivalent power and even more if you want. Inside there is all kinds of room for batteries. I would build it exactly as on the plans and adjust my motor and battery sizes to suit the performance I am looking for.

I originally bought mine with a Supertiger .65 and it flew nice and slow like its name. I wanted more power so I replaced the Supertiger with a YS 1.20 and for me it was a great combination. Later I turned it into a triplane with three OS .61. All flew very well and the three .61 OS engines gave it huge vertical and giant loops but it was not really any faster than the YS combo. With the extra weight maneuverability and glide was effected and I didn’t like it as well as the YS combo. I switched back to the YS and have been flying it as such since.

If I were going electric I like Axi motors so an Axi 5320 Gold Line

With a 90 to 100 amp Castle ESC, start with a 16 or 17 by 10 prop and two 4100 6S Pulse packs in parallel. http://www.pulsebattery.com/plu45-41...er-series.html

There is also a Lazy Ace modification that uses a semi-symmetrical airfoil and ailerons on the upper wing as well. It was called the Sporty Ace

Fantastic airplane no matter what powers it!! Mine is a 76" and had a g-23. Want to go to a g26 or dl-30 with onboard start next. Because my right arm is disabled I cant really start it anymore by myself, havent flown it in years.

Nice of you to say that, Carlos. It's not that I couldnt get a club member to help, but half the time i go out, its during the week and i'm by myself. I sold the g23 off of it some time back anyway, played with another engine but dont really like it for this plane, so its been hanging on the back burner. It is one of, if not THE sweetest flying airplanes i've had in over 35 yrs of this hobby.

My thanks to all the replies.

Dennis,
I intend on building the original sized 76" plane...everything I've found indicates its a great flying plane but there is surprisingly little written on it. Of the few places I've found people writing about it they mention that the plane can be tail heavy with the 61 2 stroke, is that true?

Good luck! That's a beautiful bipe. I think after I finish my killer chaos 60 build I'm going to try a biplane next. Maybe the sig hog Bipe. Have fun with. Walt

blunight,
Check this link out. Its on another forum but well worth the look.

http://www.rcuniverse.com/forum/gian...-lazy-ace.html

Around 311 pages of Lazy Ace info. In particular see the posts by a modeler from Austria named VOX. His work is amazing. Good Luck with your build.
