Hi everybody;

I built this for our indoor sessions this year. I love these carbon airplanes!

Specs:

42" wing span
44" long
159 grams
1.81 oz/ft wing loading
LPS RXC-C drive 10x4.7 prop
Berg micro stamp rx
2 cell 700ma lipo
Pico BB servos pull/pull v-tail

how fast does it fly? i.e walking speed? what is the maximum wind speed that it can fly in?

UltraBob

Snake: It can fly at about a fast walk if so trimmed but can also fly faster as well. As far as the wind goes, it won't take much. In fact, if the air conditioner is going in the gym it gets tossed around a bit.

I think the slower the model the better. A fast pace sounds very good, so i guess it can fly in confined areas? how much static thrust do you get from your motor setup? can it hover?

UltraBob

Snake:

It's only been flown indoors and flies just fine in a standard size gym. I think I'm getting about 4 1/2 to 5 oz. of static thrust so at a weight of 5.58 oz. it won't quite hover but will fly verryy slowly at about a 70 to75 degree nose high attitude at full power. It takes very little power to fly/float around the gym and the 700ma lipoly packs seems to last all day. With a 250 pack it might just hover but of course the duration would be pretty short.

Here's another picture with a little more detail.

I'm just asking these questions out of interest and now seem intrigued by your large indoors flyers ( compared to 30-less gram micros ). The performance is very nice so it seems. How much would it cost to build? i.e a break down of the required components?
cheers!

Snake;

If you already have servos, receiver, etc., it's not too expensive. There is probably about $15 (US) worth of carbon, $18 to $20 for the GWS drive and about the same for the speed control. The plastic wrap covering is nothing. I get my carbon from goodwindskites.com and my drives, etc. from aeromicro.com. Don't know if they ship international but they are good sites to look at specs., etc. Good Luck!

I have very little money to spend at the moment, but the price is low. Are there any other options to this low weight flying?

UltraBob

One reason I built this was that I could use readily available small radio gear without getting into the specialty really small stuff. Wing loading is everything so my standard gear required a larger than normal airplane to carry it. So even though mine weighs 5 times what some of the micro stuff weighs, it flies slower than some that I have seen. I don't know of anything else that would be much cheaper unless it was one of the toy blimps or something. Going to Hawaii tomorrow so will be offline for awhile. See ya.
