Hey all. I finally got to have my first ever go at slope gliding with my Windrider Bee on the weekend, having flown almost everything else over the years except slope stuff, and I have to say I'm hooked! Damn this addictive personality  Where would you normally have the CofG on one of these things? I've got mine at the rearward position mentioned in the manual but it didn't penetrate very well in the ~20kts of wind. How much further forward would you normally place the CofG in windier conditions like that? Does it matter where (top or bottom) the weights are put? The spot I was at is a tiny area, so I can't wait to get a go at a better slope! |

i reckon keep the cg the same, just weight it up on the cg point, there are so many different opinions in that!!!
your glide angle will stay the same but your flying speed and stall speed will increase, that's just my two bobs worth,
come to the sunny coast brent and i can show you some awsome sites,
maybe for the strong wind i might put the cg to the front position, it won't be so pitch sensitive then.
regards nick

I checked the manual for my Bee today and it states the CG should be 7.5 inches from the leading edge. When I checked mine, it balances (with no weight added) about an inch behind that point. This is where I was flying it on the weekend. So, to experiment, I went to my new 'secret spot' this arvo with a bunch of stick-on wheel weights.
First, I tried it with the CG set as per the instructions. I didn't like it. It needed a *lot* of up trim to maintain level flight, even in the 20+kts of wind. It was also slow to respond to input etc.
So, I went back to my original CG point and loaded all the weight on that point as ballast. It didn't seem to make it penetrate any better but it increased the stall point quite a bit and made it fall out of the sky in the lulls. In the end, I took all the weight off and flew it like I had it on the weekend :-)
I finally got the hang of slowly flying forward at a slightly downward angle to make it penetrate and then doing fast turns back towards the hill. Good fun when you get it right and don't get blown back behind yourself!

I think I have determined the problem with your wing flying as poorly as it does..... you mentioned that it's a Windrider Bee. There! problem solved, now go and buy something worth flying ;D

hey there, the COG as per the instructions is far to forward. start at about eight and a quarter and work your way back. generally most are around 8.5 and i generally go as far back as 8.75 for aeros. as for COG in windy conditions? that depends on how you can handle the conditions. i generally go further rearward! allows for less reflex, less drag and therefore higher speeds to penetrate the wind.

hey there, the COG as per the instructions is far to forward. Yeah, so I've found. I've been flying it at my original balance point of 8.5inches back and it's fine. I've got a BEevo now too and I've done the same with it. Left the CG where it came out to without adding weight and it also flies fine. |
