The 7lbs must be without batteries.. mine weighs exactly 3kg (=6.6 lbs) without battery and though the hacker is heavier, i have very light servo's. Without the engine at all, it would weigh 2.5kg empty, so a 6s versions can never weigh 7lbs including battery..

Hezik

Please re-read my post. The RTF weight is 7lbs 12oz including the battery.Remember I have no rx battery (bec) and the Scorpion is about 4oz less than the Hacker.

i just spray paint the canopy ..... will install the esc and do all setting , hopefully can fly it on Sunday !!

Canopy looks much nicer ... I may spray mine from inside and keep it all black

Guys

Just a little tip, unless you are flying from paved surfaces or very short grass the wheels are a bit on the small side. As our grass is not too short at the moment I changed the
wheel to 2.5 inch and omitted the spats. I have been told also to omit the shrouds to the landing gear legs as if you do have a heavy landing these will be forced back into the fuselage and do more damage. I did crack my gear plate due to catching a hole but it was an easy fix and I have used better plywood on the new plate and added some re-inforcement.

John ... I learn about the Lift Generators with my Angel. This time round I ensured that there is a gap to the fuse so that when the UC compresses under a heavy landing there is less damage to the fuse. My plane is 98% ready, plane only. That takes a mere 60 mins. Will be working on the installation tonight and tomorrow. Hope to see her fly this weekend.

Huison has flown his on 10S with the Scorpion, he is most happy. I shall let him fill us in with the details.

Don't leave off the shrouds, they fortify the landing gear. Without it, it'lll break off faster. Also they have an aerodynamic function.

I'm flying with the standard wheels, wheel spats and shrouds, off a field that is not flat, has cracks in it and long grass.

In the rougly 285 flights so far, I have experienced no problems whatsoever.

Hezik

Well on flight #3 I cracked the gear plate on a landing that was not heavy so you go your way and i'll go mine.

John

You came in fast and hit a hole in the very wet and soft grass. That is not a normal landing

Offcourse, everybody is entitled to make their own choices, that's the beauty and the pitfall of our hobby; there is no right or wrong.

However; when posting on a forum; others can pick up on that advice. In that case, I feel they should have a complete a picture as possible.

So if you state the landing gear isn't sturdy enough, wheels are to small and one should leave out the shrouds, I feel obliged to share my experience. Bigger wheels, no spats, fine, but leaving out the shrouds changes the flightbehaviour.

Again, our field is nowhere near a golfcourse and mine has survived 285 landings so far without any problem. With the original wheels, spats and shrouds. I would say the stock stuff is sturdy enough.

Now it's up to the reader to decide what to do

Hezik ... 285 flights, how many flights do you do in a day and do you work at all???!!! Seeing how nice it looks with the servos in the H stab, I am now indecisive on whether to go with the 5485s or perhaps the Futaba 9650. Hmmmmm ...

I have to train to make it look like something.. and yes, I'm a somewhat disturbed person :P

I have a fulltime job (40hrs/week) and a girlfriend. In the summer I fly like 2~3 flights every workday and about 5~10 flights saturday and sunday. Luckily my GF also likes to be outdoors on the flying field.

I made my first flight with it on May 14 this year. It's now 14 september, so thats 4 months. That's about 70 flights a month, or an average of 2.3 flights a day.

I think I just proved I'm certifiable :P

I'm using 9650's in the stab (and on roll as well) and it works fine.

Hezik ... I shall stick to my 6 flights a week! Heheheheehe ... am most tempted to get the 9650 or the new BL version. Looks so much neater.

Hi
Interesting debate about the shrouds on the undercarriage. I don't think they do anything aerodynamically. I had a minor mishap with my Angel S one day out flying that resulted in one shround coming off. I decided to fly it expecting to have to put in some aileron to compensate for the missing shround. The plane needed nothing. I detected no trim change at all. So I would debate if they have that great an effect on the handling of the plane. But they do make the plane look alot more pleasing to the eye.

I am toying with the idea of large wheels

M

Mike ... perhaps in KE situations it will be noticeable. I have a small EF Extra 300 EXP, with the small SFGs you can feel that things like KE loop will be easier. So it does so something I guess.

Hezik ... how did you get your spinner to be so close to the nose ring? I tried using the supplied M4 cap screws and I got a 3mm gap at the least.

Hi
I noticed the gap between the spinner and the nose ring was larger than I would like ( asthetically) but I just assumed it was to get adequite air into the cooling for the motor. What are other peoples experience?

Mike

Don't use the screws with a big head. Included with the engine are screws like these:


only shorter. I used those.. they are barely long enough but if you sink them into the firewall, Ã*t will fit.

Thanks Hezik ... countersunk M4 screws, gotcha!!! I think I am spending like 45 mins a week on the build. Hahahaaha ... this is gonna be one long build for a plane that can be ready in like 3-4 hrs. I am trying to get some heli ball links, they are much smoother and they do look cool too.

Mine is ready to fly tomorrow , i just weight the plane and it come out 4.350g . . . . .
here are my setup :
Scropion motor 4035-250kv - 18x10 APC-E = 77amp WOT , 2550Watts
Tuenigy V.4 100amp 2-10s ESC.
Rhino 4900mah 5s x 2pcs .

Will test fly tomorrow , see how she goes . will give a flight report .....

Hey folks,
Any chance of an E-Flite BL110 fitting into this airframe? 63 dia vs 48 for the Hacker. Thats about 8mm per side bigger. Can someone take a quick measurement. I do know it will be shorter. I can deal with that pretty easy.

BL110=295KV will probably do better with an 18x10 vs the 18x12 on the Hacker at 270KV?

Thanks!
Dave Rigotti

Dave it depends on the face of the back part. What is the diameter? I think the WindS takes no more than 50mm. The nose part of the fuse tapers and you cannot mount a flat faced 63mm motor to the nose ring mount. I do see that the EFlite is tapered too but how much is the taper? Best bet on 8S is Hacker/Scorpion and one other China brand that I now forget, same shape as Hacker. For 10S its Scorpion only so far.

Guys

I had an experienced pattern flyer fly my Wind yesterday. He was of the opinion that 6S is not enough power for the F3A schedules if it is windy. Another Wind was flying on 8S and the vertical performance was noticeably better. However I am only flying on a 3700 20C pack at the moment. My 4900 25C packs should be here this week and I will try these. As I do not fly competition the performance of my Wind on 6S is still perfectly acceptable for me. BTW excellent service and prices from Hobbyking for my Rhino Lipos.

John

Ok! I'll stick with the recommended Hacker A50-16L. Any word on these in stock in the USA yet? Anyone get theirs from Fedon Aircraft?

Dave

Better than the Hacker A50-16L, more power and cheaper.. and with a little bit of work, mountable in exactly the same way.. and last but not least.. in stock:

http://www.hobbycity.com/hobbycity/s..._270Kv_/_2100W

I have seen this combo fly and it had more power than the Hacker A50...

Reviews say different? Seems poor quality is the order of the day. I'd rather fly than fiddle.
Thanks
