  1. Greta post Pete. A lovely part of the world where we have have spent some great holidays. I assume everything stopped for 2 hours at lunchtime? smileyMany years ago, along with fellow club mates, we took part in a model show at Valenciennes, and we were treated very well, including food and dancing in the evening - oh, and a plastic dustbin filled with red wine at lunchtime that you dipped your plastic cup in when you felt like it. We all went away with a commemorative plate and a silver (plastic) cup!!

    On pulse jets, I remember these at the Plumpton Airshows that Dave Bishop used to run. I cannot imagine them being allowed at a public show in the UK nowadays.

    Happy memories from an ex North Downs MFC member.

    not an answer but these may help you out

    Garbo

    Thanks - HK support came back to me with this suggestion, and it may be that I shall have to use them (and add extra weight and congestion in an already tight fuselage space), but my main beef is that the model was not as described, and I have advised them so. I am hoping that they will provide me with the relevant bits and pieces free of charge as I do not see why I should buy more stuff that I would not have needed if the model had been as described.

    They also need to make suire the Hawks leave the factory with the micro connectors or adjust the description!

    I have now had 8 flights with the Stinger,and thats 8 flights with no crashes.smiley I nearly lost it on the last flight though.I was doing a very wide,fast turn and nearly lost orientation.It became a small speck in the distance.I kept my nerve and just kept the same input on the sticks and she came around.Its so easy to let her get too far away.

    Im really enjoying flying this jet,the only criticism i have is the paint comes off very easily. Any ideas how i could stop it coming away?

    I have given mine a couple of coats of Skin-Crylic from Falcon Aviation. It brushes on easily, dries clear and gives the surface a nice sheen and protects from minor dings and seals the decals nicely. Brushes wash out in water too.

    I did ask HK if they had a colour match for the decals so that I could touch in some areas that had flaked off out of the box, but they said "Dunno..." frown

  4. I was one of the fortunate few who snapped up one of the 12 Skyangel Hawks that appeared in the Hobbyking UK warehouse recently. It looks very pretty, but the servos now come with conventional size plugs, and not the micro plugs as described on the website and as depicted in the photos of the model.hawk plug and rx incompatibility.jpg

    Now faced with changing the plugs over to micros to fit the RX I specifically bought on the basis of the model description angry

    I have notified HK UK.

    Anyone else got the same issue?

    Hmm, HK UK have just blotted their copy book: I ordered a kit that was "in stock" and paid for 24hr delivery and it hasn't arrived two days later.

    Bill

    Not good, although I plumped for the 48 hr delivery and HK/Parcelforce delivered on time. My Stinger is now in quarantine until my birthday next week....... sad

    I suspect it is going to be a while before UK stock builds up to anything like the International warehouse levels, if ever. Also, anything desirable that comes in will tend to fly off the shelves very quickly as they are not generally available anywhere else in the UK, and are competitively priced.

    That said, on 25 August HK Admin posted : - "we're now starting air-shipments as well as containers this will reduce out of stock on small items. We will have pickup service soon. Nano-tech container is being shipped out next week."

    Early days yet....

    Edge, the Stinger benefits from having the fan balanced and if only short bursts of throttle are used, it'll handle a 4s 1800mAh - 2200mAh LiPo. Mines holding up well so far on 4s. Anyway a Radjet 420 is on it's way to keep my trusty old Funjet company.

    Have been ploughing through the reams of Stinger posts on RC Groups and it seems that 4S on the stock set up is a bit of a risky strategy given the rating of the ESC and motor. The temptation to hold WOT for a bit too long is likely to be too much! I shall fly with 3S and maybe upgrade later if the need for speed is too difficult to resist.

    The stock Stinger looks to be a good, robust and fun model - should arrive today with any luck. Enjoy the Radjet.

    David

  8. Well, finally decided to buy a Vampire from HK and.......ordered a Stinger. Reason? I realised I would have to get more 4s batteries for the Vampire right now, whereas I have shedloads of 3s lipos. Also the Stinger seems such a good flier that I should be able to have some fun with it without worrying about it too much (I do prefer scalish stuff really).

    Happy Birthday me! gift

  9. Like the strip! I bought the Panther first and I agree it is great fun. Have not tried to launch it myself yet, but will try one day. smile

    The MiG seems to fly in a more "locked in" fashion than the Panther, as I had some weird dutch rolling effect last time I flew the latter, although I need to fly it more to see if there is an obvious cause for this. Don't really care, as I love them both - they are superb fun for the money as you say and actually are pretty well finished and detailed for a foamy of this size.

    Will try and take and post some flying shots soon.

    Just maidened mine and it went really well. Many posts on t'internet about hand launch problems (initial zoom followed by inevitable fall to earth),  However, with a firm level push it pulls away nicely and grooves smartly.  A bit quieter than the F9F Panther from the same stable.

    Anyone else flown theirs yet ? - Merlin Innovations must have sold a few of these at the shows...... face 1

    The Panther flew yesterday evening, and very good it was too! Pulled away well from a hand launch (by my friend Jon) and grooved around very well. Slowed up nicely for landing and was good fun all round.

    CG was at 344/345 mm from the front of the intake, balanced inverted - this photo is of the top of the starboard wing :

    The Lipo I used was a 3S Zippy 2200mah 20C that weighs 165g. This seems to work well and was barely warm after the flight. Perhaps my cooling mod worked, and it was helped by not having it at WOT all the time. The replacement 40 amp ESC is a definite good idea for a larger lipo. This photo shows the lipo position :

    Another friend is about to get his in the air, so we shall report further - good luck with yours.

    Cheers

  12. Hi Harry

     

    Others did the work, I just gleaned from the Forums!

    I do not generally bother with differential, but when I get to fly it I may investigate. A good dose of exponential is a good idea though, as during the brief flight I had, it was sensitive on aileron.

    Anyway, the stock 30 amp ESC will probably be ok with the 1800 mah lipo provided but will not like a 2200 mah lipo. I robbed my EFlite Sea Fury of a 40amp Hobbywing ESC and I have hot-glued it to the top of the ducting as shown in the first photo below. The plastic plate with the cheater holes cut in comes off easily with a little care to facilitate this, although beware of the paint coming off as it is painted on the inside; easily touched up though.

    Other mods. are :

    • cut a cooling hole in the noseleg blanking plate to get some air over the lipo
    • carbon rod let into spanwise panel line on underside of wing, as there is a weak point where the servo cut-out is. The model survived a couple of cartwheels with this addition, so it seems to work!

    Have also received two ultra-slim 2200 mah 25c lipos from Hobbyking that fit into the battery area and can be moved around to find that elusive cg, plus a smart pilot and wing skids to protect the aileron linkages when landing on grass - again, photo below.

    Have also brushed on a couple of coats of Skin-Crylic from Falcon Aviation to help protect the exterior - it also removes that odd tacky feel of the original paint and protects the decals.

    I really want to fly it now, as the longer I cannot, the more fiddling I shall do!

    Cheers

  13. Hi Harry

    I bought one at the Weston Park show, and it is a great little package. I have scoured the internet forums for advice (and there is a lot of it about!!) I copied some of the more useful snippets and have put this at the end of this message for you.

    Maidened it last week with a 2200mah 25c lipo shoved right up the front and it seemed to pull away ok, but the 30amp ESC cut out and I had to "land". Not much damage and - now with a 40amp ESC - it is ready to go again (just waiting on the weather....).

    If I find the ideal cg position I'll let you know.

    Cheers

    David

    I just checked the CG, with the stock pack in the above location the CG is 1-5/8" behind the inlets. It flew much more balanced with the 2100 packs though, that moved the CG to 1-3/8" behind the inlets.

    I got in another flight this evening, flew it back-to-back with the Sabre for comparison. Despite looking quite a bit different, they're very similar in flight characteristics. Now that I've had a chance to compare them closely, they do seem to be about the same speed. Aerobatics are almost identical between the two. The Panther has some odd stall characteristics now and then, probably because it's still a little tail heavy. Out of curiosity I pulled the ESC off the velcro and shoved it back so that it was in the cavity between the inlets. Sure enough, it did not shut down this time even though I flew on the 2100 packs and at WOT much of the flight (to test the ESC). It appears that if enough cooling air gets on the ESC then it can handle the load OK.

    I'm flying with the ailerons on the recommended high rate (with some expo) and the elevator on the recommended low rate. The elevator is pretty sensitive even with the CG set ahead of the recommended spot, but when I was flying on the recommended CG the elevator was REALLY sensitive and would induce stalls quickly if too much input was given.

    Five flights with various lipos today, starting out with three flights with 25C 1800mah packs, and one flight each on a 2000, and a 2200mah pack. I noticed that it flew a bit tail heavy using the 1600mah stock pack, so I thought the 1800's might bring the COG forward, but I realized that the instruction manual shows the COG with the optional landing gear installed, hence the tail heavy attitude using the 1600. It still flew a bit tail heavy with the 1800's, so I tried the larger 2000 & 2200mah packs next and finally got it to balance at the recommended COG with the 2200mah. The larger packs won't go all the way up into the nose due to their size, but there is plenty of room on the battery tray for them so I gave it a go; I think I found the sweet spot! Though the Panther will fly well in a tail-heavy condition, it really flies like a dream using the heavier 2200 packs. Slow speed handling improved, and rolls were actually rolls, not twisting wallowing spins like when using the stock 1600 pack.

    Well, according to Jason at Hobby Lobby the 30A esc should be fine, but most folks on the RCG thread changed theirs out right away, (I only got one flight out of the stock esc before it failed; thankfully not while in flight). I think the Tbird 36 will be just fine, I did some bench tests and at WOT got a momentary burst to 32A, then it settled down to 28-29A, so the 36 should be fine. Though a few folks are still using the stock esc, I wouldn't want to risk an in-flight failure. HL is sending me a replacement stock esc, no questions asked, (that tells me they are aware of the problems with the stock unit), but I won't use it in the Panther. Pay attention to the supplied control rods, I ended up enitirely replacing them and the clevis' in mine. Also, the instructions show the COG at 1 3/4" back from the leading edge, but if you're not using the optional landing gear with the servo up front, it will take a 2200mah pack to get it to balance properly. My first couple of flights I used the stock 1600 & an 1800mah pack because they fit up into the nose, but the plane was obviously tail-heavy, (flew good that way, but definitely tail-heavy). There is plenty of room for a 2200mah on the tray, so use one of that size if you have one.

    had a chance to take the vh version out of the box. canopy was a bit warped, contacted vh, they are sending me another canopy.
    i noticed in the manual, they have put tape over the cg #'s, and changed the 1 3/4" 45mm to 1 3/8" 36mm. everything else is exactally the same.
    this is a father's day gift, so can not do anything until Sunday. sounds like a nice midnight project....

  14. I was baffled when bringing up the GC website to find it called GiantShark. I could not even log in, and when trying the "forgotten password" link I was informed that my email address was not recognised.

    Like others, I think it reasonable to give the new business a chance, but it is regrettable that a small, thriving business that delivered the goods and demonstrated good and intelligent customer services has seemingly been swallowed up by a larger operation.

    GC were my first port of call for modelling goods - will GS maintain that status?? The name in itself is a real PR howler....It is almost as if we have lost a friend!
