well the motor is not that big, ~100 grams , but the kv is low ,<900. that allows a large prop that's efficient and works well with the large cowl. it also creates lot of torque steer, which can be minimized by slow throttle application and enough rudder travel.

focke wulf gws fw190 in epo with servoless retracts and flaps (4 min 28 sec)

another video of my 190 with servoless retracts and flaps, with reduced elevator flies a bit steadier now thanks guys.
landing was cross wind thats why I ended up going down the hill a bit lol, need more practice.
I reduced my flight time down to 5:30 after one batt was down at 3.71v after a 7 min flight, think it was something to with weather as my p38 lightning was doing the same- batts were nearly empty when usually a good percentage would be left, maybe wind was up a bit so I was flying faster to compensate.

Very nice landing Nigel! Can't say the same for the music though

Alan

Hey whats wrong with music?
Actually the music is not my choice either, my mate video'd it and put it on you tube and added the music cut cover up all the bad language lol.
my landings this morning were spot on, really smooth apart from the first one which bounced as wind was up so i landed into wind coming over hill and landing in bumpy area. Then wind dropped a bit and i cross wind landed the rest onto smoother grass, lovely to see. I'm liking this more and more but only when the wind is not too fast as it still struggles with bumpy air!

Alan is pretty much of a slave to techno/disco/pop. He hears it and loses all self-control--probably found himself doing the "robot" all over his living room when the video came on...

Good thing he lives here in the southern US, where we don't encounter much of that stuff. He'd never get anything done! Ha ha!

Happy Easter!

Nigel,

its truly amazing to see you land this plane on grass and what a beautiful landing.

i have to many landings on this plane to count but never on grass. you may have inspired me to put flaps on this bird.

this is in general to all who have trouble landing, one thing i have done in the past and love to do is touch and goes with this plane. it looks so cool and is definatly good practice. i learned a lot with this plane one thing is to control landing height with throttle. so what i did to learn this is bring it in as if you are going to land a block away from you. then get close to the ground. now control height with throttle after flare is set with elevator. now i fly it all the way to the landing strip as close to the ground as i dare using throttle. once i get to strip i decrease throttle and kill it on landing. it is not natural at first to do this from my stand point as i learned to fly gliders first. at first trys i kept the plane like 10 feet high or so and began using throttle to control decent, this is what i do to practice when i have not flown her for a wile.

this helped when my bird weighed in at 42 oz. with a 9x9 prop and a hot motor. the problem i had with this set up is it did not have a lot of low speed thrust so you really had to be careful on landings..

anyways great landing Nigel and keep it up.. i hope you will find this bird to be one of your favorites as it is my favorite electric.

Thanks andew, yeah I will start touch and goes soon as that is how I learned to land properly in the first place some20 years ago with a big heavy cessna, I had some better landings yesterday nice and close and even with some flare out, I am still finding my way a bit with this plane and find that when I slow it down too much it has a habbit of dropping like a stone if it hits a pocket of turbulance and then thats when it bands the uc wire, but when its calm I can fly it round happily with flaps down getting it to the flare and keeping it going with throttle controlling height as you say, but I'm very wary, ready for it to drop at any moment and not having enough power to do anything about it is not good.
My landing line has trees both ends so its not really posible to do a long extended flare with this plane and still land on the nice flat ground but I will keep trying to improve and get more consistent, this is the first plane with wheels since I got back into flying as all others have been belly floppers which are much easier to land and dont have to worry too much about bumpy ground. I'm really enjoying the challenge.

I know exactly how you feel about landing with uc. I started RC flying in 1996 and apart from my Slo-V, all my planes (Mugi Evo, Stryker, Simple Delta, EDF F-35 & Tigershark etc) have all been belly landers. I've not got around to fitting the HK retracts to my FW190 yet but I'm getting in some practice with my EPP FreeAir Foker D VII bipe. Really slow landing speed but does have a tendancy to nose over on landing unless you have a smooth surface and helps if you keep some power on once she's down.
Time to have another go at landing my E-Flight Mini Funtana. I must have ripped the u/c off at least 5 times & following my last attempt I damaged the carbon u/c. A set of these has just been installed and certainly seem beefy enough with a wider stance
http://www.sloughrc.com/default.asp?...emid=F-IRVPU01 They were the same company who supplied the 3mm axles that I will use on my FW with the HK retract units http://www.sloughrc.com/default.asp?...emid=F-IRVAX30

those 3mm axles look a good idea, think I will be getting some of those next time, be easier then bending leg.
Well, been down this morning early, and nobody about, so I just practiced landings, did a few and then set up a bit of aileron mix to flap to compensate for pulling to right when flaps were down, reduced elevator a bit more and now when I deploy flaps she carries on in a streight line--much better, I then practiced touch and goes and what fun that was, I've forgoten much I enjoyed touch and goes and after a couple of batteries my nerves settled and my landings started getting nice and consistent and was getting smoother all the time, I was really dissapointed when my 5 batteries were all used up and then my mates turned up with there planes, charging up now cant wait to get down for another session.
Might think about putting more flaps on as glide slope is still very shallow and long but with cross wind landings feels more in control with a bit less flaps, we'll see how I feel next time lol.

@ Nigel and Headless,

Very similar findings on landing this thing. At any rate, finally installed the flaps. I find they help a good bit in favorable winds, but possibly intensify "ballooning" in winds of 8 mph +, especially in crosswind. That said, I'm very happy with the mod, got some delightful landings out of it this past weekend. This was my first plane to get flaps. Suppose I'll forgo the retracts for now, at least until I get more practice using flaps.

glad you like the flaps, makes landings nicer when winds are calm dosn't it?
I hinged mine on the line already there when you cut out flaps and so the hinge is glued well into wing same as ailerons, also you cant see them so no need to paint them but your method may actually provide more lift as mine will have a gap when flaps are down.

I've been kicking this around for a while (more tempted with my P-40 because it's so dang heavy and I like how light this one is). I thought I'd probably go with plain flaps instead of split flaps. Your work makes me more convinced that's the way to go--just seems like a very straightforward mod.

Did you mention anywhere what size servos you used for the flaps?

Thanks,
Jeff

Hey JMAH. It is straightforward and they serve the purpose. Lots of fun to play around with once finished. I went with the HK HXT900's just because I have a bunch of 'em.

hxt900 all round, they are great, had some beautiful touch and goes this morning and landings stopping at my feet! It was really calm though, yesterday was just a touch of wind and much harder to nail those landings. havent tried landing without flaps since putting them and retracts on, I keep thinking I should have a go just in case retracts dont come down and I have to belly it. wouldnt fancy doing that with flaps down as its all so close to floor with wheels up. But I find it comes in pretty fast with all the extra weight so will just test it if retracts dont come down lol.

Hi , Is your p40 epo? WHat does it fly like? I often think of getting one.
