[HR][/HR]>butyrate dope as it's fuel proof.
Only to a degree ... but for C/L stunt you're only likely to be using low/moderate levels of nitro so you should be okay.
Butyrate over nitrate is okay as a finish coat for that purpose ..... nitrate over butyrate means a recovering job.
I have seen this discussion elsewhere but danged if I can find it in a hurry.
The short is butyrate over nitrate. And the best that can be said is dope is fuel resistant.

When I fly a plane that uses rubber bands, I cut them off with a knife. That way, they will never be used again. I've found that the fuel can deteriorate them in only a week, and they become dried out and cracked, and easily broken. As you note, it's not worth the risk.
For me, I always use fresh rubber bands.

I used a few to few rubber bands once. Started hollering that I was getting hit (72mhz). Then I started flying much smoother and gentler. Problem went away. After landing I was told to add more rubber bands. No more problems.
But I usually build with bolt on wing in mind now.

My instructor who taught me 30 years ago told me to use 4 on each side with half of those crisscrossing, never had a problem. He also told me about having a Tupperware container full of corn starch to put the used rubber bands in, worked like a charm. One box of rubber bands would last the whole year!

If you have trouble sleeping tonight, just watch my boring maiden video, and you'll be asleep in minutes. I'm doing two things here; just trimming, and checking battery capacity to see if I can exceed 10 minutes. Really exciting touch and go's at 4:20, 6:00, and 7:30 minutes on the video track. https://www.youtube.com/watch?v=PdEA...m-upload_owner
Video was taken with my Hatcam, sorry, no zoom.
Yes, it'll do about 12 minutes with reasonable throttle management. zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
Don't fall out of your chair.

Nice vid !
Congrats on your successful maiden.
Refresh my memory, please. What motor, esc, prop, battery combo are you using ?
Your Kadet flies much like my ARF Sport did. I know that you will enjoy yours.

It was all very well worth it, because I now love it. It is slow, smooth, and precise.

Thanks for the info.
My "new" ARF Sport will be powered by a 32 sized motor, on 4 S with a 12X6 prop. I was hoping to maiden it, along with the yellow one, today, but it was too windy.

The Turnigy G-46, 420 KV pulls like a mule. You need to be careful though, there are 3 different KV ratings available. You need to select the right one for the job that you want to perform. I selected the 420 for long flight times, in lieu of high speed performance.

Thanks Ed, I have an old Kadet Senior I want to convert to electric so the lower Kv rating should be the right choice, more pull less speed, right? I'm new to the world of electric motors so I appreciate the info. What motor mount did you use for the Turnigy G-46?

My G-46, 420 KV motor came with a mount. It also comes in 670KV, and 550KV if you are so inclined.

Here's a question to add more confusion. If the low kv motor can swing a bigger prop, can't it also swing a higher pitch prop (of smaller diameter), and get the same speed as the high kv motor?
Or, what will be more efficient/faster? A 10x8 prop at 10,000rpm on a high kv motor, or a 10x10 prop at 8,000 rpm on a low kv motor? Or use whatever numbers would seem reasonable.

" A 10x8 prop at 10,000rpm on a high kv motor, or a 10x10 prop at 8,000 rpm on a low kv motor? "
Realistically, using run of the mill motors, you are never going to reach 8,000 rpm using a 10 x10 prop on a low kv motor. For example , a 400 kv motor ; means that with no load on it, it will spin at 400 rpm per volt. So if I use a 5 cell, 18.5 v battery, 400 x 18.5 = 7,400 rpm, and that's with no load. And so, you would never come close to 8,000 rpm with a prop attached to that motor. You would need to go to a higher kv motor to get to 8,000, and that's why they make both high and low KV motors available to you . Choose wisely. You are correct, it can be confusing.
What is best when you get into electric, is to start with the manufacturers recommendations, and then get a Wattmeter. So then if you want to play around and use something other then his recommended props, you can use the Wattmeter to see that you do not exceed the Maximum Current for that motor ............... Or else you might start smelling some very expensive smoke.

What do you mean by Sig Brotherhood #120; Sig Kadet Brotherhood #155 etc. etc.; also are there any photos of how to make ailerons for the stock wing of the Sig Senior? I have a new wing kit but no real idea of how to make ailerons or what are referred to as barn door flaps; I seem to remember seeing photos of such but can't remember where I saw them posted?

I have been unable to edit my above posts and provide you with the correct Youtube link., The original link has changed since I shortened the video.
For what it's worth, my maiden flight shortened from 10 to 5 minutes. >>> https://www.youtube.com/watch?v=yHY8utSkQW0

There should be pics of how I converted the stock Kadet Senior wing, to a barn door aileron wing, in this thread.

Goodness gracious, I have found you on the kit building boards as you said! It is funny to read everyone's stuff and know exactly how they felt when stuff went south or wherever the "bad" direction is! Does Balsa USA stock kits? I always thought they just supplied balsa around the US?
