I got carried away today playing with funnels, upright, inverted, forwards, backwards, clockwise and counterclockwise.

I've just started to be able to get all these funnels working and it's really fun, it gives the flight a cool 3D touch.

It's always when you're having relaxed great time that you forget ... fuel level. I remembered as the heli stalled in a backwards inverted low funnel. Crashed on the tail.

Well... this will be the occasion to replace my 7 years old HawkSE by a new HawkPro. I've started shopping around, quite impressive the price differences you can find, specially with currency conversions. The cheapest I get for now is from century uk, approx 170€.

The problem is it's not clear if they include the new stuff from 02/24/10 (yellow, blade holder, red dampers, remote glow, ...) that's on the Century web site.

Anyone now if TowerHobby sells this latest version?

I suggest you buy the newer NX50 and build it as a 30, it has so many new updates and upgrades it make the price difference well worth it,, plus you get the much cooler NX Canopy,,
all you will need to make it a 30 is the 30 T-Tube, 30 Boom and Boom Linkage, you already have the 13 tooth Drive Pinion..

Jim: I've seen it's in stock... but are you sure it is the latest verison, with the upgrades dates 02/24/10 (yellow, blade holder, red dampers, remote glow, ...) that's on the Century web site.

I'd already considered the NX50 path and got put off because I clearly wanted a cheap to fix heli, so 550 makes it cheaper because you can safely stay with wood blades, plastic head, even doing 3D stuff.

I didn't know it would be easy to go 550 with the NX just using the parts you list, thanks for this info.

However, I'm planning on reusing exactly the engine/electronics from my HawkSE, and it doesn't have good servos, so I'm afraid the NX50 ECCPM would require me to add an extra 200$ for 3*S9252 or whatever... then if I damage one of those in a crash, it gets expensive.

Also my old HawkSE will give me a few parts to reuse, and the NX is more expensive...

So all this put together, I'll stick with the HawkPro I think, it suits my needs, and I like it's somewhat "bulky" flying style.

Well, that's it, just passed the order to an all new HawkPro, from century uk (good currency conversion bewteen Pound and Euro makes this a good deal compared to heli-world, + shipping costs are lower and no customs/taxes and stuff). Unfortunatly, the special offer is only valid from heli-world, so no free blade holder/remote glow/3d paddles/red dampers/...

Looking forwards to building a brand new one of these 8 years after I bought my HawkSE. In the meantime, I'll start stripping the engine/pipe/electronics of the old one, get it all clean and looking new to be ready to put it back on the new one.

That Hawk's been incredible! 8 years intensive flying/bashing. I advise it to anyone who wants a cheap/reliable/capable heli for training. Sure, mine's a bit smooth (some say bulky) compared to my Swift620SE, but the 620SE is 5 times the price (it's got good electronics, carbon blades, all carbon/metal, ..., my Hawk has sub-standard electronics and is full plastic/wood). I know some people have them much more aggressive (carbon blades, good electronics, metal head, ...), but I want it to be cheap and I like the smooth feel it has.

I'd say average 4 flights a week, that's 212 a year, 1700 flights. I usually fly 3/4 of the tank (about 12 minutes).

It's had two engines (changed the engine last summer).

Probably around average 4 crashes a year, that's 32 crashes. It's totally stock and on wood blades. I've always only replaced the broken parts. What's great is that it's no hassle, when it's broken (usually around 70$ including shipping), just replace what's broken, and you're back where you were.

It has so much slop in it now (swash, bearings, balls, sliders, ....) that I wander how it manages to fly as well as it does(did). Some bearings are literally destroyed, I know this, but it doesn't seem to stop it flying.

So, I'm going to get the engine/pipe/electronics out and put them in the new HawkPro, and hopefully I'm back on track for another few years flying. Maybe I'll get a bigger tank!

One question: I gather the HawkPro comes pre assembled. I would have prefered a full kit version. Whatever, is this pre assembly done well usually, or should I start by a full disassembly?

I would remove all the Set Screws and re-Locktite them so you know for sure they are safe,
and make sure all Screws that have Bearings on them are not over tightened (like Bellcranks, Mixers and Washouts),
and check the Gears for smoothness, this includes the Tail Gears..

OK, I'll check these. The bearing screws are easy, I just have to check the parts move freely without slop. The setting screws are more of a nuisance, because if I take them out I'd prefer to put new ones in as replacement, because the heads soon deteriorate on these (taking them out if there is locktite wears the heads).

I've removed the engine/pipe/radio off the old Hawk... I remembered then why at some point I considered stopping NP! After taking the fan shroud and engine out I looked liked I'd overhauled the gear box on my Toyota Celica! What a mess, oil all over me and the table! These NPs are messy!

Whatever, it's all on the workbench now and I'll be washing it all with Alcohol to get it nice and clean for the new HawkPro.

The old HawkSE looks like a wreck with the broken undercarriage, bent boom, broken blades, bent side frames, bent flybar, no engine/radio, damaged canopy, ... yet, for a few $ (around 60€ I'd say), it would be back flying. I'll take it fully apart, junk warn parts (bearings, balls links, sliders in particular), clean the others and keep them for spares (or sale on ebay, don't know if this works well).

Hopefully I'll receive the new HawkPro next week, I'm looking forwards to having a new one of these (just hope the kit is complete and no packaging problems, but as it's ARTF, this should be OK I guess). In the meantime, I'm going to test the Gyro on my TREX250SE to see if it fixes the tail wagging problem.

Received the new HawkPro, it's looking good, I like the new canopy/torque tube/double boom support (new compared to my HawkSE from 2003). I like the beefy/sturdy look this heli has. I did a bit of cutting out in the side frames to get my OS50Hyper in and kept my metal fan and clutch bell. I was surprised the clutch bell is plastic now! and the tail is single bearing, maybe I'll keep my triple bearing from the old HawkSE if it doesn't have too much slop, I'll check.

Just a few comments (for Century's SixSigma Continuous Improvement TQM Plan -if you don't have one, PM me -), it's a shame the manual isn't sometimes more specific about where to find the hardware (the hardware bags could have been numbered so the manual could say "... take M3*16 from bag E3 ...", you get away with it by measuring the screws, so one can't go wrong, but it would make it more user-friendly), and also, for example the tank isn't assembled, and from what I can see, there's nowhere in the manual that shows how to assemble it (I looked in my HawkSE manual that was a full kit and that has detailed instructions). Overall, I find this manual (photo manual for final assembly) less good quality than the HawkSE one (drawings of detailed build and assembly), at least for the build/assembly part of it.

Whatever, the heli's looking great, things are nice and snug/precise/strong, the pre assembly seems good. Hope to finish the build for next week and get some test flying going with it ASAP.

You may find that the former Hawk Sport manual is a lot more clear in assembly etc.

Indeed, this manual is much like the one I have for the HawsSE. But the Tank design is a little different (than the one in the HawkSport manual), the "nose" (where the "lid" comes on) doesn't stick out as much and there's no strap anymore, maybe because as the nose is shorter, there's no room for the strap. I guess the rubber will sweld and hold the lid in place when I tighten the screw, and the strap isn't needed anymore.

After a few initial setup iterations, here is my new HawkPro, flying really well, really pleased with it :

Watch at YouTube

It's fully stock with wood blades,0S50 and cheap electronics (Servos, Gyro, ...)
