View Full Version : Advice wanted re: Quarter scale floats
11-19-2005, 10:45 PM
I want to put my SIG quarter scale Cub on floats.
I noticed that the Sig Floats are slightly longer than the Balsa USA floats.
Balsa Usa advertise that their floats duplicate EDO's floats right down to the last fitting.
That's nice but how well do they perform compared to the Sig floats??
As well if not better. The main difference is that Sig's are a sport float and have a very unscale-like mounting system. BUSA floats give you the full meal deal....but you pay for it.
The picture below is a one third scale cub on Balsa USA floats, but it gives a great indication how well they work...

It looks great.
Is it a Sig Cub?
It looks like an OS engine, but which one?
What is the all up weight with the floats.
Hey! Two different Airplanes! And one is American! :shock: :wink:
yup..two different pictures, two different airplanes..
That is a Balsa USA Cub built by Lorne Hansen and exquisitley scaled out! I can't remember what it weighs, but it is powered by an OS 160 twin...

The Gemini 160 is one of the engines I am considering for my 1/4 scale cub.
Also have a gemini 120 twin, 25 cc us quadra with electronic ignition, 31 cc Ryobi weed eater conversion, and Quadra 35.
I am new to gas engines.
Comments about which engine to use would be appreciated.
Thanks in advance
I can give you my opinions on two of them..my friend had a us 25 and had a lot of problems with the internals.. I've had 2 ryobi's and don't really care for them..too much vibration and not enough power..

It's the OS gemini 160 for sure.
OS 160 is a lot of engine for the 1/4 scale!!
You will be capable of 3D maneuvers!
I would think the 120 would be a better choice.

Thanks. You are right.
Didn't realize the 160 had that much more power.
I don't know if you guys are talking about the same engine..the Gemini 160 is a 2 cylinder 4 stroke and has the equivalent power of a 120-ish single cylinder. ......

Let me clarify this for all who posted.
I have two OS gemini twin cylinder engines.
One is the first OS Gemini twin which has considerably less power than the OS gemini 160 twin which is the second twin I have.
I did fly a quarter scale Balsa USA Cub with the Gemini 120 twin and it flew very scale.
It was probably a bit under powered.
When landing I was at 1/3 throttle
A friend of mine tells me his 1/4 scale Sig Cub on floats flew fine with the OS 120 Gemini twin.
I felt that the extra drag from the floats warranted the use of the 160 twin instead of the 120.
I didn't realize the 1.60 was that anemic.
It will probably be fine then, but you will likely need some tailweight added!
Glad you started this thread Ken. I'm looking at big float options too. My cub has an OS 91 four stroke twin....just kidding, the dummy cylinder is made out of coroplast, even has a glow plug gooped in the right place!

The Sig floats aren't too expensive.
They are a little bit longer than the much more expensive Balsa USA floats.
If you really want scale floats the Balsa USA are scale EDO floats.
Go to their web site and check them out.
I also may have a line on fiberglass floats that look like the EDO floats.
Don't have a price or conformation on the glass ones yet.
