This is my review about the invictus the quality is very bad
people have to look out because The foil is wrongly placed
As you can see on the 2 movies on YouTube. As you see the foil is placed
In the wrong direction and in the flight it came off.
Normally you should cover the foil from the back to the front, leaving a small overlap facing downstream.
This manufacturer mistake cost me the plane

This manufacturer mistake cost me the plane and a 4s nanotech 3.3 lipo, not to mention a lot of work. Also the foil
has very bad glue so people have to check the hole plane
as about the warranty i am not happy white it

I have many planes included EDF and turbine, this one is awesome, I felt it solid like a rock. Glide well at low speed and stable at high speed. Good plane to invest for your daily flight at park...thanks Hobbyking

A really excellent model in both design and quality. The kit really is top notch and for the price, especially at the recent sale price it's top value. Build was reasonably straightforward but there are a few things to point out related more to the ancillary components than the kit itself:

. Despite using the recommended purpose made Hobbyking NTM EF-1 motor I found that the cross mount that comes with the motor is much too big to fit the mounting plate on the model. Luckily I had another cross mount that was almost the correct size, but it would have been frustrating if I hadn't had one in the spares box. Even using the alternate mount I had to slot the holes slightly, the mounting holes in the motor box seem to be either non-standard pitch or inaccurately set.
. Similar issue in fit of the motor to the cowl length. The motor was too short, the prop driver ended up some way back inside of the cowl. I had to add 6mm spacer behind the cross mount to move it forward so the prop and spinner would clear the cowl (so buy some 6mm NTM long spacers along with the motor!). With spacers installed fit was perfect, about 1mm clearance between spinner back plate and cowl.
. The recommended 16g (for ailerons) and 21g (for elevator and rudder) servos were too small for the cutouts (Turnigy servos). I had to make some ply infill plates.
. The bottom of the elevator and rudder servo hit the s

I have previously built the LR-1A Pogo, Shoestring and Proud Bird. The Invictus is by a long shot the best ARF of the group. Quality shipping, quality fiberglass parts and quality model finish make this ARF fun to complete and fly. Only two issues. Had to add 0.375" standoffs to the motor (HK's motor) which was not addressed in the instructions. The ready to fly weight turned out to be 3 lbs 12.2 oz. A little overweight. Cost to door for ARF was $195.56 including shipping.

RE: Anyone for EF1 ??
MAIDEN FLIGHTS , REPORT ...... INVICTUS !!!

today i flew the maiden flights ( 4) in total . the maiden flight was successful, and went quite well with no hicups and minimal trimming req . take off and landing went very well , as i heeded some advice about airspeed on take off . ( thanks Claudio) .
2nd take off was woefull , as it lifted off and nosed up then torque rolled to the left , i had to lower the nose and hope for the best , just managed to clear the trees at pemac , then flight full speed etc and inverted , the plane would fly level on 3/4 speed but lift on full speed ,and felt twitchy in the air; inverted flight seemed neutrally balanced as it flew level inverted . upon this i concluded that it was slightly tail heavy .
3rd flight changed C of G 5MM further forward, a better take off but still torque rolled to the left , plane was now a smooth flyer , i also reduced the lower dual rates from 60pcnt to 50pcnt for this flight , and it flew better as it was now balanced well and on full throttle flew level , and slightly downward when inverted , twitchyness was now gone , landing was a cinch , just throttle off and touchdown with sink rate very nice .
4th flight i fine trimmed and practiced some circuits at full throttle , plane was very smooth and controllable on quick turns , performed very well without over banking on turn in etc , take off went well

All I can say is WOW! Shipped from Hong Kong to the US, not a scratch on it due to the careful packing using a large amount of bubble pack, and wrap. The Cowl and Pants are carbon reinforced. Paint is Excellent, and covering looks very professionally done. Instruction manual is well written and understandable. Well worth the wait. Thank you Red, Ben, and the Product Development Team! Well Done!
