I don't mind flying my other planes in a bit of wind, but the mossie doesnt like it. The wind beats her around alot. If its calm, she is a dream to fly.

Has anyone tried GWS props on this plane?

That's because the Mossie has an under-cambered wing.

Which ones? None of the two-blade props that are a good match for the airframe will fit. Besides - all she needs for nearly vertical takeoffs & big, round loops is a good battery. In fact, she can still do a loop with a 17g keychain cam strapped to her belly!

Are the 2blades to big?

Yup. The stock 110mm x 80mm 3-blade prop only clears the fuselage by 4mm, and the 5030 & 5043 are the only 2-blade GWS props that are a good match for these UM planes.

Third flight

The first two flights went well but this one was a different story.
I felt more confident after successfully flying in some wind and decided that the very moderate winds of today should be a piece of cake.

So here comes the painful modesty learning process:

My second flight took place with 10 knts winds, gusting 18 knts but in an open field area. Today I decided to fly nearby my building with 5 to 6 knts winds but it was much more difficult.

The proximity of the building and of the trees created much more turbulences than the 10 knts wind in an open space.

So I must now consider both wind strenght an proximity of obstacles to evaluate the strenght of the turbulences.

All in all the Mosquito ended up her flight in a tree and, when landed again, I had to repair wing tips, elevator tips and consolidate the rudder. All this was done with hot water and tape and she will fly again.

Doing so I realised that the propshafts could be moved 1 and 2 mm in and out which worried me since I have read on this thread numerous stories of popping shafts or propellers.

Should I open up the nacelles to check or one would consider that it is normal functionnal clearance. If I have to open how do we remove the plastic exhaust pipes?

Many thanks for your answers.

Now I understand.

This is not a mater of wind or of newbeeness. I have just been cursed!

And I realise now that this thread is 666 days old!

Not a good day to fly.

Gaexcalibur, would you mind directing your curses to someone else's plane?

I am getting a little bit nervous.

1mm of axial play in the prop-shaft is about right. There has to be some play to prevent binding.

Many thanks to you Joel and to all those who shared information about setting up dual aileron, differential and spoilerons.

Undertook all these mods and the plane is a joy to fly. No more adverse yaw and very little rudder now for coordinate turns.

I flew her seven additionnal times resulting in 1.15 hours flight time, sometimes in 10 knts winds gusting 16 and all went fine.

I have noticed that once you have set spoilerons you could program them so you would lift them 1 mm or so as normal mode, not landing mode, which would somewhat reduce the tendancy to lift the nose in case of facing gust.

Another trick is, when possible, to fly her downwinf when it is gusty. So you would feel the gust before it hits the plane. If you are flying laterally to the wind you may lower a little bit the upwind wing which would help to stabilise the plane.

Caveman AS3X, for what it's worth...

New mosquito owner

I've been a (very happy) owner of a Champ since August. I just picked up a Mosquito a few days ago. I may be a little over my head with it. It's not exactly a four channel trainer. I may decide to sell it before I destroy it.

But before I do so, is there a way to switch the rudder control from the left stick to the right stick, so that the right stick is rudder and elevator like the champ? I assume I have to open it up and change a connection.

If it's too much of a hassle I'll sell it or trade for another three channel plane like a mini super or one of the flyzone planes.

Thanks
Dennis

Doing that will only teach you bad habits. The mossie is flyable only using rudder,but basically, don't switch it, it's like saying I want my sport car without a rev dial and SUV seating position and limited slip diff because that's how my tata nano is.

That's called mode 4. Most modern programmable transmitters can be switched between modes. The vast majority of pilots in North America use mode 2 - where the rudder & throttle are on the left stick. As AP said - don't do it. Learn to fly 4-channel the proper way, by using rudder, aileron, and elevator in concert to make coordinated turns.

Alright, in regard to what Joel said, you can fly mode 4, but you shouldn't change it between airplanes. The rudder on the champ induces a lot of roll, that's how a three ch plane works. While the mossie rudder does induce a lot of roll, it's not gonna fly well using the rudder like you do on the champ. The rudder is meant for yaw and ailerons for roll.

You want the main lateral control - whatever it is - on the right stick - on the Mosquito that is the ailerons, on the Champ it is the rudder.

The Mossie is a fairly gentle four-channel flyer but you do need plenty of room to fly it. There are probably better choices for a four-channel trainer, though I can't think of any micros that would be better ones off the top of my head. Perhaps someone else has a good suggestion along those lines.

I successfully used the UM T-28 as my aileron trainer. Same batteries as the Champ. I got the Mossy for Christmas. Had it out a couple of times and it seems more advanced than the T-28. I have to keep the speed up in turns and am playing with the expo to soften up the response.
