Hi all, I've got my 30th coming up in a few months (that's right, i'm a big boy now) and i'm trying to pick out a good plane to 'suggest' as a present. Buying a $250 parkzone plane like a T-28 is probably a bit out of the price range, so like most, I find myself perusing the hobbyking catalogue. This is something I'm leaning towards right now: www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=13763 It's sort of a mini stryker, as shown in this picture here from RCGroups  I'd like to run 3s zippy 1300mah 20Cs, 4.5 to 4.75" prop, and get this motor for it as well: www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=5353I'd also upgrade to 9g servos and reinforce it with lots of CF. Any thoughts, opinions? |

Haha John, a bit more ribbing for our antipodean pal.  On a more serious note, I realise these are more expensive than the HK thing that you've posted Dillz, but if it's within price range I think you'd do well to consider the MPX Funjet. It's a well known platform that can be butchered around as much as it's owner likes (100+mph versions abound) and is from a trustworthy stable. I suspect that Fly would recommend this bird too. Tough as old boots is a bonus on something of that size and speed. I don't know how strong HK's foam is, if it's as good as MPX then fair enough. I'm not convinced that it will be. If you are not set on a jet looking thing, then I'd suggest the MPX Gemini. It a massive improvement over the SC and is just a huge pleasure to fly. If you don't trust my views, ask SCC, I think he has a similar soft spot for his as I have for mine. As for the motor you have posted, did you read the thread where myself and Fly were talking about these types of EMax's? They are OK motors, not much more than that to be honest. The bearings aren't the greatest and the mount tends to work loose. With bigger servos, lots of carbon etc. I'm not sure that you'll be overly pleased with the performance that you'd get with that motor. You'll need a bigger prop or higher Kv than that motor to get any reasonable efficiency. |

Well, you're barking up the right street but you have a blind dog.
Assuming the Stryker is yours (?) and you have some experience with jets already then a FJ should be a strong consideration. Figure $40 for the HK job +$20 shipping and you are up to $60. For not much more you can get a bare FJ frame. I've never seen the HK one but the FJ is one of the nicest put together planes I own. You don't have to carbon the hell out of it unless you intend to go > 100mph. I'm running mine ~ 400W on 4S and it's mostly stock frame. I have no idea how fast it goes but the park gets kinda small fast.
It will run on about anything that fits properly. The motor you chose is 26gm. That's .....tiny..... unless you are going for a superlight job which is one approach. They also aren't much of a motor-I've got a couple but both are re-wound. Wire is crappy, bearings ain't so hot, and mount is dicey. They are barely a cut above TowerPro.
Small motor, 1300mA lipo > that's a recipe for keeping it light, floaty, and NOT, repeat NOT heavily reinforced or you screw up the lightness.
It's kinda small. Small things going fast get tiny even faster.
You need more thought about this project.
IS that your Stryker?
Addendum-there are myriad and LONG thread on both the Stryker and the Funjet. Most of them are about going even faster. FAST---costs $$ and brings weight with it. There is a nice rationale for going simple, quick and light. There are some really tempting light Stryker builds I may attempt sometime should I ever actually get the old Stryker fixed. I gutted it to repair and put the motor in the FJ. I'd say the FJ goes 20% faster with the same setup.
I took a closer look at that HK jet. If you do get it, just leave it alone and fly like it is I'd say. It's basic but probably OK. Not worth paying the price to gut it and then build on an inferior shell. EPO is not nearly as good as Z-foam or Elapor. Kind of like thinking you want another Cub to build so you buy and RTF to gut it and build it---wasted money.
I think the servos won't last long without protection. I'd also go metal gear in that kind of application.
Boy-these guys are rough on you!

No Dillzio that thing will get away from you in a flash fly away or end up in a tree, you need something that will not suffer from operator dysfunction or human error, to this end I have scanned the web and found the perfect plan for you, is loads of fun, is sporty, has a great motor, great colour scheme, once flying will not suffer from the above, will not suffer from fly aways and like a boomerang usually comes back to or near to the operator, see below: www.toyday.co.uk/shop/index.php?act=viewProd&productId=3955   ;D |

My tuppence worth - Get a PNP Radian PRO ( You do have a radio/ RX don't you?). Wont break the bank, is relatively sporty, Made of trusty EPO foam, and really is a pleasure to fly.
As a second plane, I'd say it's unbeatable!

John, cubcruncher, thanks as usual for your invaluable input. Ging, the multiplex funjet does look like a nice buy, it's only $100 retail over here, twice the price of the parkjet but not completely unaffordable. I'm not too keen on the Gemini, I want to get a way from the classic plane shaped models for my second. Something F-16 shaped would be nice, but I thought it might be better to get my practice up with a relatively cheap flying wing. As for the motor you have posted, did you read the thread where myself and Fly were talking about these types of EMax's? That motor I picked is an Emax? I never would have known, how can you tell? Fly, the stryker isn't mine, i just stole that pic from RC groups. I have no experience with flying anything except for my cub (other than on the simulator). Can you post a link to somewhere that sells the FJ for me so I can check it out? Who's it made by? I chose that motor because the once that comes with the parkjet seems pretty crap. The motor I chose is heavier than stock (26g vs 20g), has a thicker shaft and a higher KV value. I thought it would be a nice step up from stock, without getting something with ballistic speed that would be way beyond my capabilities as a beginner anyway. If you don't like the look of that motor, could you suggest an alternative? I was also looking at these two: www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=5453www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=8620It looks like 1300 is about the biggest battery you'd want to put in the funjet *EDIT oops I mean the Parkjet*. I don't think improving the stock HK parkjet would be much of a waste of money really, i'll be using a spare ESC from a mate of mine (or the one that comes with the plane), servos I've got, and the motor is only $6. Toff, I do like the Radian, but for my next plane I want something QUICK. Thanks for the ideas guys, keep em coming. |

Have you considered any of the Rtf parkzone micros like p-51, they are great to fly in calm conditions in a small field

Nah, I think I've got the jet bug mate. Ever since seeing my mate fly his HK blue angles EPO mini-albatross i've had the bug for something that really screams!

John, cubcruncher, thanks as usual for your invaluable input. Ging, the [glow=red,2,300] multiplex funjet[/glow] does look like a nice buy, it's only $100 retail over here, twice the price of the parkjet but not completely unaffordable. I'm not too keen on the Gemini, I want to get a way from the classic plane shaped models for my second. Something F-16 shaped would be nice, but I thought it might be better to get my practice up with a relatively cheap flying wing. Oooh ye of little faith. See a Gemini fly, fly one yourself. You'd fall in love with it. F-16 eh? I've got a soft spot for the Phase3 version as and when I get another bird. That's very nice with a couple of strengthen mods (see RCG for info on that). Experience dear boy.  I have one in the TV depron Mach3 delta I built, may not be the same Kv but looks the same. The number (CF2805) also gives it away. When Fly is saying FJ he's just taking the common abreviation used by those in the know, I've glowed a part of your reply earlier, which should give you an idea.  TBH, I don't have much experience of this size of motor as I've tended to use bigger or much smaller (9 gram for the MPX Fox conversion). In the FJ, are you sure? My mate flies his on an old 2250 20C 3s LM I gave him, and a ~4000 3s that he got from HK. Do you have the packs required for it, if not you'll have to buy those. Admittedly they aren't expensive but more cost anyway. As Fly states (and I can comfirm from the depron Mach3), small nippy airframes get away very, very quickly. I notice that the HK is only 2 feet in WS, at any pace that'll have you wondering about orientation in no time at all. Even the Gem (it's pretty quick at WOT btw) gets me worried when I take it a fair distance away, and that's not that much smaller than the SC. If you want a cheap and cheerful and pretty fast, tough birdy, you could do worse than a delta, such as the one that Admiralev and his club mates crash together. Search his postings, you'll find info on the particular one he has/had. There are other similar ones of course. EDIT: Found Admiral's thread... HERE.P.S. EDIT: Have you changed the linky to the HK motor? I'm sure it was a lower Kv version than it shown now (1600 v 2840).

OK, no jet experience. Then I don't recommend the Funjet (FJ) but I'll give you info. My rationale is that I was probably flying longer than you have been when I got my Stryker B-that's the ancient BRUSHED one with NiMH and a direct drive 480. I had broken off the nose and ripped out the motor complete with mount and foam attached to it within a minute. I would do that at least a half dozen time before I got a handle on the speed and the orientation required. Jets are a real different type of plane. The FJ is more expensive and a nicer plane than the Stryker. Personally it hurts me to trash a plane like that while learning. The Stryker is a better candidate for trashing/learning, flies well, parts are available (PZ after all), fixes just like the Cub, and pretty cheap. It's a good platform to learn and not hard to build from scratch. I repeat, it flies well and is a proven plane. That Parkjet is a HK cheap, untested chance. I've learned to let other folks take those chances. The few reviews indicate there are some real shortcomings. So you are really buying an untested, small, $60 chunk of lower quality foam to rip apart and start over. Not really a good deal in my book. First, some Stryker reading If you want to go FAST and cheap: Stryker motors: High performance, low cost Turnigy 28xx comparison www.rcgroups.com/forums/showthread.php?t=1213360This would be more in line with the Parkjet and could be cheap, fun, and a good way to get into jets. Easy to upgrade later should you get the speed bug. F27 Stryker - Lite version www.rcgroups.com/forums/showthread.php?t=471443www.rcgroups.com/forums/showthread.php?t=530040#post7637294A more comprehensive 'how to' for building. www.2kool4u.com/stryker/The FJ is a Multiplex product. No idea where you would get them. There is also a new 'Ultra' model that is already beefed up for speed since a massive number of folks push this airframe very hard indeed. www.multiplexusa.com/model-kits/funjet.htmlThe threads on the FJ are REALLY long, be warned, but that's also the sign of a very good and popular airframe, like the Cub. Multiplex Fun Jet, Park Flyer Foam Airplane Review www.rcgroups.com/forums/showthread.php?t=621504Multiplex Funjet "Fast" setups... www.rcgroups.com/forums/showthread.php?t=642067There are a lot more but that should be more than enough for now. You can easily make a lite FJ. My buddy has one, flies it with a Little Screamers motor (small) and a 1300mA lipo. Either of the last motors you posted would work fine for that kind of application (on the Stryker too) and be a bit of a jump up from the EMax. The 2730 is a better motor than the Hextronic 'Blue Wonder' (no longer blue). FWIW all the motors in that price range have crappy wire and crappy winding but the basics are better than the Emax. I have a bunch of the Blue Wonders and they are a favorite candidate for rewinding as are the 2730's. Re-wound they are an excellent motor. The wires on the Blue Wonder are the winding wire extended out-this makes it stiff and prone to breakage. A delta is an option too, generally similar in performance and somewhat less likely break off a non-existent nose. A blank delta core to build will set you back probably $30-60. A Stryker core is $20 and you can make most of the parts. A FJ core is more like $70 (without shipping, US prices). That makes that Stryker a cheap option. There are a LOT of EPP wing cores so that's a discussion unto itself. |
