HI people,  The guys that have this jet,  Do you think the 25-46 size
retracts could be installed or bashed into this plane?  We are on grass
and I wonder about the 15-25 size retracts as this plane is just over
their weight limit.

Thanks
Tim

Well I'm all out of parts to bolt on my Habu 32. I guess that means I'm done with the build. After 10 days of rain off and on, the weather looks like it will be good for the weekend. So, I'm looking to do the maiden tomorrow.

I weighed mine, and it came in at 3,087 grams (6.81 pounds) with the Blue Lipo 6S 30c 5000 mAH packs. It feels really heavy to me, but I am used to giant scale 3-D/IMAC planes, not jets. It is lower than what the manual says to expect, so it should fly OK.

I got the Habu 32 to see if I would like flying jets. If I do, I may move up to a turbine later this year. This will be my first semi-serious jet flight, so wish me luck!

The landing gear that comes with their 15-25 size retracts isn't used - the gear that is supplied with the kit is of better quality for the weight of this jet according to Horizon's manual and is used in the retracts. The worst thing that can happen is they get bent - unless it gets dorked in which case would rip the gear out of the wings. I can't give you an answer since Horizon hasn't sent the fan to me yet - everything else is ready - receiver / transmitter is all set. In fact, I have the 9303 working better than I ever expected - not an expert programmer by any means.

Maidened my Habu-32 today, all went well. So, here is my report from a jet novice point of view. I have to say is that this is an easy, fun little plane to fly. Weather today was a little mixed, but much better than it has been out here in San Diego. We had a 10 to 15 mph wind that was mostly cross (blowing in), to the runway. This had me a little concerned since this is my first jet, and I didn't know what to expect. Turns out, the Habu doesn't much care about the wind; it just tracks straight, and even crabs nicely on landing.

My setup and control throws, are exactly as suggest in the manual. They work very well. I suggest everyone start there. I set mid flaps and mid rates for the maiden take off. Our field has a clay surface, so is a little rough after the recent rains. Still, the Habu tracked well, took off in about 200 feet, and climbed out with authority. I put the gear and flaps up, switched to low rates, and began to trim the plane. It took two clicks of down, three clicks of right, and the plane was trimmed out.

I was a little concerned about the differences from what I am used to in flying a jet. However, this plane is very easy to fly, and I was quickly comfortable. The manual says for advanced pilots, but I think any solid intermediate pilot should do very well with it. As Tony F. previously said, it has no bad habits. I flew four flight with the Habu today, and by the end of it I was comfortable enough to do 4 and 8 point rolls, slow rolls that took the length of the field, knife edge passes (coupling here, will mix later), and inverted flight. I even got half way around a rolling circle before the plane got too small and I chickened out. I will get to them soon though. I found that I actually preferred to fly on mid rates even at speed. Maybe it is just because I like the extra rudder throws. I will be turning up the rudder on low rates.

After seeing the videos, and other jet pilots having so much trouble with landing, I was expecting it to be much more difficult. However, with throttle management this jet just settles in nice and easy. No tendency to tip stall, and a nice comfortable pace. I started landing on high flaps, and mid rates as suggested in the manual. By the last flight I found I liked mid flaps, and high rates better on landing. This could be the result of the higher winds today. I will probably use full flaps in light winds. I did have one flight where the nose gear did not come down (loose connector, my bad). Between the wind, and the high rates, I was able slow the plane way down, and set it gently on the mains. It was going so slow when the nose finally touched that it only got a small scuff mark under the nose. It just scuffed the paint, and was easily covered up with a black sharpie.

I really am not experienced enough to judge speed in MPH, but the plane flew with enough speed to be entertaining, but not scary. That could be because the plane is so well mannered. Verticals were impressive; the plane went up until I pulled it down. For now the speed is enough for me. I think the real adrenaline junkies might want one of the upgraded power packages. I will probably go there some day as well.

I had my timer set on 5 minutes. With the mixed type of flying I was doing, 50% aerobatics to get the feel of the plane, and 50% full speed passes just for fun, the 6S 30C 5000 mAH Blue lipo packs came in nice and cool. I flew for 5 minutes, when the timer alarmed, I did a gear pass, and landed so probably 5 1/2 minutes total. The most I put back in was 3380 mAHs, so six minutes with my flying style will be easy on the packs. This will change as I get more aggressive .

This was the first Habu-32 to show up at the field. It got lots of positive attention just based on looks, and the quality of the kit. It also has an impressive flying presence. I think HH has done a great job on the Habu-32. I am very happy with my purchase. It is a fun change of pace for me. I am anxious to get more flights on it tomorrow.

Steve

Thanks for the great account! That really builds my confidence for the first flight which will hopefully happen next month (I still need the BO'd fan). I got all the throws plugged into my 9303 using the 3 flight modes. Looks like I'll only have 2 switches to worry about - gear and flight mode switch - everything else will be automatic. Weather here in PA is atrocious - cold cold cold - not supposed to warm up until the end of the week.

well just got mine in, I probably wont even mess with the stock motor ill probably pick up a mega from efflux. What do you experts think of Hs82mgs for the surfaces? Im not gonna cheap out this plane but ive got 4 of em looking for a home so i would only need 3 more.
they are MG and have way more TQ than the mc 35 HH recomends. BTW efflux RC how much of a MPH increase can we expect to see using your motor, and how much will it affect run time?

We are using HS 85bb for the most of the flying surfaces (6 ), and HS 82MG (2) for the rudder and nose wheel steer.
We sent the E-flite/Mega unit straight from the test bench to Cory, (see photos)  to assemble and fly the first demo unit.
I have and idea on the speed, but I'm not talking  speed until it  flies, and we know for sure. We will provide fight video and Doppler the speed.

The Stock setup is mentioned in the instructions as being about 5.4 lbs static with a bellmouth intake for testing.
Our Combo tested at 6.4 lbs static thrust with the stock F-flite inlet lip.

If you used the same Battery as E-Flite does, your flight will be a bit shorter (it has to be your using more power) ... but the XPS 65c, batteries should take care of some of that.

Here's some of the items we have instock for the Habu32
...Tam's trailing link strut upgrade for the E-Flite retracts
...XPS, 6s, 65c, 5000mAh lipo
...Castle ICE 100 ESC (ICE 75 for the stock set up)
...Hitec servos,

Thanks for the quick reply I dont see what the difference is between the 82s and 85s except for the aluminum out put, according to TH the 82s are even lighter and faster???
Guess ill wait and see what your results are before I drop the coin, Thanks again

My fan is still on backorder; however, I was given the name and location/phone number of a dealer in Orlando that now has 6 left - I just ordered one. If you'd like the info, pm me.

Flew my Habu 32 for the first time today. Both flights went very well. I have a mostly stock setup that includes the recommended retracts, motor, fan, ESC etc., I decided to use a HS82MG for nose gear steering instead of the plastic geared JR recommended by HH. I'm using the 30-40c Blue batteries in 6S 5000 config. I also decided to use a separate regulator and a 500mah 2S LiPo battery to run the receiver, servos and retracts. I would NOT recommend using the BEC on the ESC, I experienced problems with the receiver browning out when doing full power ground tests. Our club has a paved runway that is 15 x 300, which I thought was going to be problematic, especially for landing, but as it turned out our runway is plenty long for both take off and landing. My experience today was consistent with what others have said, this is not a difficult airplane to fly. I would, however, venture to guess that this plane would probably not be very forgiving if it was not built or setup correctly. I was landing and taking off with about a 5 mph headwind so I used full flaps for landing and no flaps for take off. I mixed in the recommended down elevator for intermediate and full flaps, which turned out to be very close to keep the aircraft level as the flaps deployed. Max speed attained today was 124 MPH measured by radar. I feel like I can get a little more speed on the radar after I settle down and get more comfortable with it. My plane weighted in at 7lbs 2oz and when you pick it up it feels like it is so heavy that it would never fly with those little wings, but fly it does, and quite well at that! Hats off to the folks at e-flite, they did a great job on this one.

Great looking video - your photographer did a great job as did you. I am troubled you had problems with the recommended ESC since I already bought one. I know some of the guys are using ICE units with their BEC's - and, I also thought about using an alternative power source for the electronics, but, the trade off is added weight. Of course, if it crashes due to a receiver not getting sufficient power, moot point. I think I'll shoot off an email to Horizon asking them for a bit of data to support their recommendation on using their BEC/ESC and see what they say. I'm pretty sure what they'll say - how much more weight does the 2s LiPo add to the Habu, btw? I have a few regulators lurking around the shop and it wouldn't take much to add the 2s and the regulator. Your flying area looks a little cramped, btw - your landing approach has to be a bit steep - but, you did a fine job of getting on the runway. Are the gear holding up OK - one person said they had a slight bend due to the frailness of the gear which prevented full retraction on a subsequent flight. Thanks again for the good report - my long awaited fan is due here this Tuesday.

One other question - what did you use as the balance point for the aircraft? The forward, middle, or aft area?

I am using the tiny Castle regulator that is very small and light. The 2s lipo is also tiny and lightweight, I charge it after each flight, although I could probably fly 3-4 flights safely without charging it. The whole package is probably is about 2oz. The gear are holding up well. My first touchdown was very rough but nothing was bent or broken. Our field looks more cramped than it really is but the light poles do add a little "spice" to our flying! Our runway is not nearly as big as I would prefer for this airplane but it you touchdown on the approach end it's no problem.

I used the middle balance point recommended, I believe it is 112.5 mm behind the leading edge. CG was fine here.

I know I should know this ,,,But,,, to use a seperate battery for servos do I take the red wire out of the speed control RX plug and plug the speed control (std.80 amp E-Flite) into the throttle port? Should the switch on the speed control be "on"? I plan to use a 2000 mah.NiMi 4.8 volt pack. I am going to use 8 of the HiTec HS82mg's on this jet.
Thanks
Steve

You could just leave the switch off and that would work also but i'm not sure what would happen if the switch got accidentally turned on. The safe thing to do is disconnect the Red wire. You could save yourself some weight by using a small lipo and regulator rather than the 2000mah ni but I honestly think the extra couple of oz will not matter much overall.

Just get a 3 inch extension and cut the red wire. Leave the esc wires alone.

If you haven't already done so, pick up a copy of RC Jets - there's a great article concerning our Habu and it is very well done. It's quite an endorsement.

I flew my Habu 32 today for a couple flights. The second flight I had a brown out and lost the control for a few seconds. Not a good feeling.

I am running HS82's for everything and I think it is just too much for the 2.5 amp BEC. So I will add a seperate battery to power the RX.

The Habu flew well with about 3 clicks of right ail trim. Flew rock solid and at a good clip for an EDF.

Used 3500 ma out of a 5000 battery. This gave a good 4.5 min, usually at full.

Wow - a brown out isn't nice - I'm wondering if everyone should add a separate battery for the servos to be safe - gotta think about that. I am using everything that Horizon suggests - I do disable the nose gear servo when retracted which should help a little I guess. Ready to balance the plane and should be able to fly this week or next if weather cooperates.

We now have the E-Flite 15-25 elect retracts, as well as A123, 1100mAh, LiFe battery packs. These packs will plug directly into your reciever, eliminating the possibility of ANY BEC failure.

I think a separate BEC is a must on this plane.  Especialy if you use more powerful servos.

You used the retracts?  I thought you guys in Canada would still be on skis this time of year.  LOL.
