Looking for a biplane kit (not ARF) in the 1.40 engine range. Could not find any...help is appreciated.
Thanks.

Look at:
Balsa USA's 1/4 scale bipes [& tripes]
Proctor
Glenn Torrance
Flair
FunAero
plans for many more are available, if you can scratchbuild, or have someone cut it for you

What era / plane are you looking for??

Thanks, will check. Looking for Stearman/PT-17 bipe. The only one that I like.

Look at the Midwest Stearman kit, 90-1.20 size.

World Models has a range of Ultimates with one that size.

At the size you want, try the Flair giant scale PT-17 kit , the Balsa USA 1/3 Stearman kit, Bob Dively Stearman kit, or a Ziroli Stearman, which comes in two sizes, IIRC. A few kit cutters offer the Ziroli Stearmans as kits. There is a NIB Balsa USA Stearman listed for sale on Ebay right now--just saw it last night.

Here's the link. It didn't meet reserve so the guy may work with you on the price. [link]http://cgi.ebay.com/BALSA-USA-1-3-SCALE-STEARMAN-PT-17-KIT_W0QQitemZ330217598548QQihZ014QQcategoryZ2563QQ ssPageNameZWDVWQQrdZ1QQcmdZViewItem[/link]

The BUSA Stearman is a very large airplane requiring a 4.2ci gas engine or larger! There are not very many aerobatic bipe kits left, much less designed specifically for a 1.40 4-stroke. The Lanier Pitts was recently discontinued. The Balsa USA EAA bipe is still available in a kit (for now) and would be a good match for your engine. You want to stay in the 8-9 pound range with about 60-65" wingspan to keep it fun. Good luck.

P.S. If your set on a Stearman the Midwest kit looks like the only option.

Busa's Phaeton 90 would be a good candidate. Flew mine with a saito 120. A 140 would do nicely. Lots of info here on rcu about this kit.

One other option is to spring for one of the old Sterling PT-17 kits that are always popping up on Ebay. There are usually a couple listed every week or two--I see them all the time on there. Average selling price is around $150-$200. A 1.40 is likely a bit much for it, unless you are looking for some 'very spirited' performance.
The 77" span Ziroli PT-17 is the next closest size option, aside from the Midwest kit. IMHO this is probably the best match size-wise for the 1.40. The plan calls for a 35-42cc gas engine, and a finished weight of 16-20 lb.

I have the Great Planes PT-17 ARF, and it's a very nice flyer. I'd have much preferred a kit, but there isn't a lot to choose from for kits of this size any more. The Ziroli Stearman is offered as a short kit on his website.

Consider whether or not a 23cc glow engine makes more power than a 23cc gasoline engine.

Ok Rick,
I'll consider it......... Yep, even a 2.40 glow engine would be a disappointment on a aerodynamically dirty, 18 pound Stearman biplane. A 1.40 would just be dangerous.

ElectRick

My Feedback: (2)

My Great Planes PT-17 weighs 13 lb, and it is recommended to be flown with up to a 2 or 4 stroke stroke 1.20 (although mine is electric). A Ziroli Stearman would presumably weigh only four pounds more, so a 1.40 should be doable, at least on the low end. Military Stearmans aren't meant to fly like a Pitts anyway.

What 1.40 engine do you have?

JMHO.

I found this one this morning, got distracted and decided I had to build it myself.. (yeah another one on my todo list)
If you feel like cutting your own parts this would be a great Biplane
