Just one quick glance at this superbly crafted Extra 260 is all it takes to be impressed by it's quality, look harder and you will see that this model is a serious performer.
The Balsa/ply construction is of the best quality and weight saving without compromising strength has been achieved as a result. More clues as to the quality of this model are given away by the carbon fibre under-carriage and wing tube. The covering is excellent quality with a sharply contrasting colour scheme that is ideal for orientation.
Built with 3D in mind, the hardware is heavy duty, servo horn extensions are provided, rudder is pull/pull, ball links are used throughout on all control surfaces and so on. This Extra 260 would be just as happy sport flying, so you don't need to be a hard-core 3D pilot to appreciate and enjoy this truly superb aerobatic model. For 3D flying a 30cc Gas engine, or equivalent electric power train would be best, for sport flying a 26cc Gas engine or Electric equivalent offers plenty of performance for classic aerobatic maneouvers.

I have had 2 of these now.
First one only survived 3 flights. I had installed a too small servo for the elevator(5kg.cm) and in a dive, I couldnt take it out of due to the lack of power from servo.
Second one has had 15 flights now.
Overall it is a nice plane. But you have to do things to the structure before flying with it! the list is as follows:
1. Reinforce enginemount. (It can flex too much and will end up in breaking. Easy fix with some 3mm plywood in odd places(Weight gain is around 25 grams)
2. Reglue baseplate for landing gear. It is not glued from factory! Atleast not properly.
3. The tank which comes with the planes can not be used as a pressurized tank. It will split.
4. Put o-rings on the wheelshafts otherwise it will have a very long landing due to it runs so smooth.
5. Close the enginebay compltely of with a plywoodplate over the servomount for gasservo. This will keep out any oilresidue. The airflow through engine bay will find its way into fuselage.
I use an YS 110 on this, and that gives the plane unlimited vertical power:-) Take off in 1,5-3 meters.
Plane weight is 3945 grams with reinforcings.
When handling the plane be careful with the wooden bars running the whole length of plane(bottom of fuselage). I have broken them in 3 places too easily, but its easy to fix, and you cant see it from outside the airplane.Flies ok. landing gear folded first landing(soft landing)broke spark plug and ruined plug cap along with some other damage. had to fab throttle & choke servo mnts. no screws to mnt. control horns to servos. be sure and beef up landing gear and fire wallthe Front Motor Mount area ,,is Very out of shape ,, Very Warped Ply wood ,out of shape ,,need to rebuild whole fount to remount properly the Motor fire wall ,,all out of practical shape in wrong slant angle oposit to rotational of set ,,,all needs revamping changes to angle ,,motor twisted wrong way ,,should do circles with out turning anythng ,,no flap to turn with this motor pointing to the left very Bad ,,out of prospective need make new Firewall ,to mount motor ,,,I bought the scratch n dent version of this, The quality is fantastic and all the parts were included, some of the covering will need ironed but that is to be expected, Seriously its not hard to figure out how to put this together! Good work HK if I could give it 10 stars I would.Can Any 1 give Me a Manual or type instruction , this Is not a good start ,For My first Big 26cc Plane ,.Possible Help files not exist ,,Many faults i found ,,from Bolts not fitting or lined up with whole ,,needing re drilling and flap Hinges need to replace with decent hinges before anything And price Is not seen in Quality ,Yet i only Just started , Give me another day to assemble properly and i let you Know fully the time taken to Finnish this Extra 260 Plane apparently fast to assemble ,,Garbage .. Many seamed Better Tho .not with Carbon Parts such as this .so in the end I better be Happy .as i was to get it ,,not to discover the faults , just fix and Be happy type thing ,,As your got No choice after receiving .,,it Cost Me $292.00 ..shaking my head still. but its what i wanted..just not the unseen facts .
This ARF kit is poorly constructed. Alot of the covering peels before or during 1st flight. Some plywood used was too soft, they can be easily bent and broken easily. The lamination of the ply splits too. A few places were not properly glued (e.g. magnets). The pre-cut slot of the wheel pant does not fit, a new hole new to be re-cut.
The pushrods where tap with single direction threads, this cause some confusion for anyone who are used to heli pushrods. To get the crevices attached, the crevice at 1 side need to be rotated clockwise to get in, while the other side needs to be rotated anti-clockwise to tighten.
Although the plane is design for a DLE30 (or MLD26) mounted inverted, the precut hole for throttle is on the wrong side, and too low. So, we will need to DIY a servo mount.
A DLE30 is overkill for this. 18x8 prop has very little ground clearance. But it has ample power to pull the plane. The plane takes off at half-throttle, using a new DLE30 that has not been broken in (only seen 1 tank of fuel on the ground.) Does slow loops at half throttle. Lands very gentle, slow and easy.
It flies very well, as if there is a gyro in it. I didn't need to give it much corrections during simple loops and rolls to maintain direction and altitude.
Overall, I am happy with the purchase, given then the price is not too steep. I guess, if I want better quality, I will need to lookIt is exactly the same wooden construction as my Peakmodel Extra 260. This one has carbon landinggear though!!
It was a delight to fly and was VERY stable in knife-edges.
I used a Moki G180 (gas) with a Krumsheid "banana" muffler and i ended up close to 6kg. Still good flying qualities, but i would use a as light as posible set up now.
The area where the landinggear attaches is weak (as usual).
If this one gets to the Euro warehouse, i will have a hard time to resist it!!
