Status: offline 		This is my Nemesis Elektrovirsion (not NXT).
Setup: Scorpion HK-4015, ThunderPower 4S 4400, ESC Castle ACE 200, prop APC 8x7.3
It is my 3 plane, because two previous was crashed!
All symptoms like Martin post. "Then, on final, she would float and float and float at around 80 km/h (50 mph)......"
Usually i can landing at 3-4 try. Tail whell always broken at the start...
But i like this plane, because it is realy crazy one!








Ralph make for me one motor 4235 and already shipp it.
I waiting a new model Nemesis NXT (like your), and i hope try it on 10S.
I hope on my practice with previous model and your advise...

Status: offline 		wouldn't it be possible to ad flaps to these models?
Both the bigscale Nemesis and Nemesis NXT have them and this shoud reduce landingspeed a lot??

Status: offline 		Yes, definitely! I would wish for flaps and even a crow configuration as with gliders: Flaps down, ailerons up on landing. that should do the trick! But I would not dare to add the flaps to the existing wing. don't know about the internal structure. So it would have to be built in at the manufacturer's side... Michael, do you hear us?

yes I hear you...

Gordon, you plane has an dry weight arround 3400 so this is ok...

We fly with 5 and 6 S (3400-4400 mAh) arround 3000-3200 Gramm and landings need room, also ailerons a bit up to get her down...

I know it is not easy landing, but the Airfoil we use on this plane was given from the 3 times in an row Reno Airrace winner with Nemesis on 8,5 ccm glow engine.. so the airfoil works.

Having 3700 and 4000 gramm on start... will fly and speed, but this also will need space for landing.... like Jon Sharp said: it is built for race, not for landing.

I can tell we have about 80-100 landing on our planes, not all of them very good, but we test and we crash planes befor we release... I know the small nxt is kind of a b**** by landing, but if you are not extremly heavy and have a bit space for landing it is not to heavy to land. I would suggest give the ailerons 3-4 mm up by landing and fly not full trhrottle in the last round... Important, the airflow design on my planes is extremly good, so you need to take a slow round to cool down and get the speed out of the plane. If you are to high and you have to dive get on the ground the plane will speed up again.... We have the problem on the place we use to fly, on the right we have an 2,5 Meter High fence on the left we have an Walking way about 1,50 meter higher than our field.... Scary when you come from left and an bicicle comes quick from the left. On the Nemesis and NXT E we have plenty of flights with different Pilots and we had also some not so good landings... ok never crashed that hard like Martin... I am thinking about the flaps... but more wood and 2 more servos... not help keep the weight down...

Status: offline 		Hello Everyone,

to be fair with Michael: I agree. The airfoil ist great and the airplane is so smooth and slick in design that it actually flew over 250 km/h on just 6S! And that is the goal with this plane, isn't it? Mine was simply too heavy! So do reduce weight where you can! start with 6S 3000, not more. And do put the ailerons up. I did not do that. God knows why, since I had that hunch. My bad.

as with extra wood and servos needed for flaps: an extra 100 gramms or so for the benefit of heaving flaps that will slow the plane down by increased drag AND produce a massive amount of additional lift: My guess is the good will by far outweigh the bad...

Cheers, martin

Hi there,

We are not unfair with Michael not all, he is a very nice guy, excellent builder and designer and delivers an outstanding after sales service !!! And I consider this platform as a place to share ideas and experiences. I also believe that the weight might not be the biggest problem...heavier airplanes just fly faster but the angle of gliding is the same ...what worries me is the obviously naughty behavier of stalling ... so I think a little washout of 2 to 3 degress could make the differncs or wing fences (which is what I a m going to try) and should maybe have considered in the construction from the beginning...

If flaps are not feasable then we have to do what Michael suggests...make a big huge turn with engine idled and bring her in for landing...so we will see...

Status: offline 		 Hi, Sorry, I wasn't trying to say that you are being unfair. I just felt that my report might come across as not doing Michael's outstanding work justice... 

I guess I was flying "old style" as I have learned flying man carrying aircraft: you fly a neat pattern with defined rectangular downwind and base leg. On a fast airplane like this one it involves quite steep turns, which might have led to stalling at - for this aircraft - considerably low speed... So a wide 180 degree turn might be a better idea.

Hello Dzhamal, Gordon and Martin,

I would suggest give the ailerons 3-4 mm up by landing


I will try it tomorrow, and post for you after...

Otherwise i have tail CG, and already two Nemesis was killed at the start (during take off).

Nice take off, nice flight, and crash at landing...
I use flaps (4mm Ail up). It's realy work. Speed was reduced.
Unfortunately i reduce speed very much (it is always my mistake), and can't rule it on final turn, and crash it.

I hope that the next flights will be better

Hi Michael,

since my plane is not delivered yet (the one with the Picco P80 DF you have received).........if the construction of the wing can handle it; can you cut out the space needed in the wing for the DS6125 servo's for flaps and also the flaps themselves?
I'd like to try the Nemesis NXT with flaps as the servo's only weigh 28 grams each, and the benefit could be really huge in slowing down the plane.

Best regards,

Edwin

Hi there,

I finally received my Nemesis NXT Attached some pictures...I was surprised how the retracts problem was solved. Not sure wether this is a proven concept or more an experimental setup...what do you guys think of this ?

Anyhow I will maiden her soon and will keep you posted...

I was do one flight. I fly with CG at retract gear point. But it was very back CG. The plane fly very difficult. I think it will be closer to front part of the wing.
