I must be crazy. It was -3 out and my fingers were getting frost bitten, but i braved the cold to fly the extra.

You might recognise the tune, but perhaps not the version.

Man i think im done with flying in the extreme cold. It was -2, with about -5C wind chill about 10mph. After about 5 mins my fingers had nearly dropped off. And after 8mins the battery completely died and i dunked it in from about 30ft and broke a prop. I was not even contemplating putting another prop on. Packed up and went home. More snow forecast tonight.

Cold As Ice (2 min 39 sec)


Trying some more harriers. Question - do i need more expo on my rudder? I seem to be getting wing rock (see 1.00), or is it the wind or my dumb thumbs.

Hi Jimbo. Definitely not an expert here but IMO it's best to see what kind of wingrock you might be experiencing in calmer conditions. 10 MPH can make any harrier less than ideal. Thats what I'd do first anyway.

I must be crazy. It was snowing heavily today. So we went to the park again. You can see the landing, it was a soft one for once!

Looks like your wee man had a good time. I can see me making a snow man tomorrow with mine

LOL, the plane is covered in mud, and i cant get rid of the stuff.. I left the undercarriage behind again, and man it was windy, you can see the plane get blown about.
School was closed
Still no boarding? If we have 6inches you must have about 3ft up there.

Naa I reckon you've got more snow than us at the minute. Makes a change eh. We're supposed to be getting quite a bit over the weekend so we might get a chance to get up the hill next weekend.

Well I took the time to look over the crash damage. Motor is done for, 2 of the magnets are cracked in half. The airframe should be fine with a few small pieces of CF reinforcements, although it will be ugly.

Anyone have any recommendation motors from HK for this plane? I can't afford to spend $45 on a new motor...looking to get one for under $20.

I found this that might be of use to you:

"For your 3-D rates, start with 75% expo for both rudder and elevator. If your high alpha rolling harriers are not axial, but jerky, you have too much rudder authority and so increase the rudder expo to say 85% and try again. Conversely, if your rolling harriers tend to have the nose drop out of high alpha, you have too little rudder authority and so decrease the rudder expo to say 65% and try again"

I suggest starting with 75% on everything and going from there. I believe that Doc Austin (used to or still does) fly everything on 45degree throw, with 75% expo.

Try reducing the rudder expo in 10% increments after trying on 75%. I have seen guys fly wiht only 20%expo on rudder I think, to give more control feel, but 75% would be a good starting point for everything.

Last I checked, Ido flys with 25% on ailerons, but can't speak for his settings on this model.

It will come down to personal preference probably.

Good post that makes sense when you think about it. I'm not very good at setting models up with the radio, I tend to just set it up where I think it should be and then just get used to flying it like it is. I'm better at tweaking the cog to my liking since I got into Twisted planes, I used to do the same with that too.

Sooo i started the build of the removable wing version and i can't understand what i'm cutting in the second step. It has 3 measurements, am i cutting it so the end of the tube has no foam around it? Also the 3rd step looks like something is wrapped around the CF tube and has a measurement of 80mm but i have nothing i could wrap my CF tube in. Are the 2 tubes that go in each wing supposed to go all the way to the end of the wing? Anyone with actual pics of the removable wing would be awsome!

Any help appreciated, i'm building this for a friend so i really don't want to mess it up.



EDIT: Figured that part out by moving on to the fuselage. When i got to the green wing tube holder i realized the cuts are to accommodate this piece while still allowing the wings to touch. Soooo i just laid that piece against the wings and cut the wings out to let that piece sit nicely in the middle.


Still haven't figured out what the string looking part is on the tube there is and i also don't understand how the wing tube will stay in the middle. Won't it just slide between the 2 wings since the carbon tubes dont have any kind of stopper?
