tried the 5x5, all good. flew beuatifully, still mentally fast, ESC cool after a full battery. Managed to break both the props i took down with me though - jesus i'm going through props with this thing!

sweet thanks for that, i hadn't gathered what ou'd done there, but will def put those ties on the clevises. hey! look what i just found! cheat sheet on these planes http://www.rcgroups.com/forums/showthread.php?t=1622693 lots of info, and a guy who got 134mph out of his t28! looks like the 6x4 is slower but longer flight times. recommended prop for speed is APC 5.25 x 6.25 - i don;t have any of those around but will order a couple. will mount the 5x5 for now.

would love to see the pics, please do post! the 30 amp esc that overheated was totally killed, in the bin. I cut a vent in the cowl just in front of the canopy, maybe that increased airflow will fix it. Failing that i've got a 40 amp esc i can chuck in it, but i'll give the hole a chance to work. i broke my last stock prop this morning. i reckon i'm going to chuck a 6x4 on it. Choices are 6x4 or 5x5 i guess. Any thoughts on props?

took it out this morning, got a few mins in and lost throttle again, this time on a different 30amp esc. esc was seriously hot, seems to be dead. i guess this is probably due to the complete lack of any air going through the fuselage, i think i might cut a couple of holes in the fuse to allow air through, see if that fixes the prob. will post pics if i do it. you having overheating issues?

FYI I just took the funfighte out for a blat and noticed that the motor mount had come loose after a bonk on the nose. the glue looks to have been pretty poor to be honest. i've taken it out and re-glued it in with gorilla glue (tacked with a bit of CA and kicker) should be much stronger. would prob recommend a dab of gorilla glue or epoxy over the mount to toughen it up a bit having seen the glue fail.

HAHA! I love that rection to the 4s. I was just laughing out loud, and the same, going "JESUS!" - it's bonkers isn't it! totally bonkers little thing! yeah i ditched the esc straight away and dropped in a 30 i had lying around, though that seems to have been glitching so i'll try another. the one i had in is an ebay crash damaged thing, think it may not be up to the job. what reinforcement have you gone for in the wing? extra strip of cf?

awesome! The T28? how have you cable tied the control horns dude? not sure i can picture it. thanks for the tip. re the wing, i'm under the impression that a strip of fibre tape along the bottom of the wing will do it, that's what i've put on mine.

i got mine from hobbyking global warehouse, took forever to come and by the time i'd paid postage and customs fees it wasn't nearly as cheap as it looked. best get it from the UK warehouse, where they came in to stock about a day after i ordered mine from hong kong. http://www.hobbyking...Warehouse_.html they do the rarebear as well http://www.hobbyking...Warehouse_.html and the sea fury is in stock in the uk too i think. there's a load of funfighters in the range, though i've heard of the wings breaking on the spitfire and mustang. i'd def put a strip of fibre tape across the bottom of the wing before you fly. *oh yeah just remembered, you're going to want some 850 or 1000 mah 4s lipos. Not a battery size many of us have got lying around in a drawer.

the noise is actually down to the prop-in-a-slot design with this one. it's the stock prop for the motor, same exact pair as on the funfighter t28 i got, so that's not the cause of the noise. the prop in a slot config is noisy whatever you run, and so i guess with this powerful setup it's just very very noisy.

yeah it's totally bonkers. great fun! highly recommend it! I've read a lot of people going on about how good the funfighter series are, particularly the rarebear. the t28 looked good too and was on offer so i thought sod it i'll get one. seriously loving it, just bonkers quick. good for well over 100mph aqpparently, though i haven;t given it sustained full throttle yet so i haven't tested that.

I just got a funfighter T28 for a bit of a laugh Maidened it on 4s (1000 mah nanotech) AWESOME! What a fantastic little thing it is! Only prob was a bit of a motor cutout issue which was probably the old ESC I whacked on there, will swap that out and see if it fixes the problem. Vid here:

I souped up the firefly. I bypassed the 2212-06 plan and chucked in a funfighter motor on 4s - turnigy nanotech 1000 mah! It goes! It's better than I thought! But wow it's loud. like seriously loud. Here's the vid from this afternoon:

hey you don;t need to join a club - i taught myself, loads of peole do. a sim is really helpful here (I use phoenix but there are others) and then start with a trainer, you'll be fine! when you crash an EPO foamie you can usually just glue the thing back together, it's all good. Just to be clear - by trainer I mean a trainer aircraft, not a human trainer! there's lots of trainer-type models available. They fly slow and stable, very forgiving and easy. The faster models give you little time to react so you need to have got to the point where you don;t need to think about what you're doing before you fly them.

sorry to have to agree dude but that's not going to end well. you'll have smashed it up in seconds. you need to start with a trainer, and ideally a sim as well. there's lots of decent trainers available, people would recommend parkzone supercub, bixler, or various others

hey dude i'd be interested to know what bits you got, how much they cost, how you put them together and how hard it was! I'm thinking about learning to fly a multirotor at some point to film with, but don't really know where to start. need some knowledge innit

Here's the top of my slipstream you can see it's covered in packing tape, bits of strapping tape on there too, and funky refractive tape leading edges. pushrods are CF tube with piano wire ends, motor mount is a foam block on the back with liteply glued on, winglets are coroplast cut from signs I had lying around the office. Here's the bottom: dark colouring makes it easy to tell which way up it is at a distance. This wing has been nailed in to the ground face first at high speed several times and still going strong, although it isn't as pretty as it used to be! oh yeah metal gear servos are a must- nylon gears will strip at the slightest bump.

it looks lovely doesn;t it. i'd suspect that to get it going fast you'd need to ditch the power pod motor mount and do a bit iof chopping about to get a more rbust mount in place, but given that and a bit of reinforcement i see no reason why you couldn;t make it fast

ooh i hadn't seen the storm - it's a bigger slipstream from the sound of it. you don't need to choose between size and speed, that 50" wing could be made to go 100mph I'm quite sure of that. You'd just need more power is all, and a bit of reinforcement. I'll take some photos of the slipstream wen i get home - away for a few days;

As requested a thread on the slipstream wing from flyingwings http://www.flyingwings.co.uk/store/index.php?cPath=101_102 This is a 1 metre EPP flying wing. It was recommended to me by a guy I met on hackney marshes who was flying one His was rigged for fpv. Mine is a more standard build. I've found it to be an excellent wing. I've crashed it hard lots of times and it's still in the air. I've modified it a bit from the original setup. Power is 2212-06 2200 kv outrunner http://www.giantshark.co.uk/221206-2200kv-brushless-outrunner-motor-p-402397.html this is an excellent motor and I have several of them. currently it's got a 3000mah 3s lipo and 30 amp esc. here's some passes for speed It's covered in packing tape which I got from flyingwings. I have lost the original motor mount which i bent in a crash and instead mount the motor on a foam block with liteply glued to the back, much like the way the raven motor mount works. It felt fast at first but now I am used to it Im going to upgrade the power when I get around to it Not top of the list. I plan to go to a turnigy 2836 2350kv on 4s. Clearly with the 3000mah lipo it is a heavy bird, 2200 or 2500 would be more standard. I'm going to move the motor forward when i make the changes so it will balance a smaller battery and sacrifice a bit of flight time for performance. I've added an extra CF strip for reinforcement as well as the original one, and put my own low-profile winglets made from a coroplast sign Happy to answer any questions!

yeah dude if you look at the blurb for that plane it says "nt recommended for the complete novice" - you're going to crash that and break it. you're best off with a flight sim and a trainer (there are lots of options on which trainer covered in threads on this forum). i'd keep the spit on the ground till you can fly a bit, then go have fun with it a bit later.

Hey dude here's the build manual for the raven http://www.flyingwingsmedia.co.uk/ravenbuilderskit.pdf there's no strapping tape required for the build. you can get it straight in the air with no further reinforcement. if you decide you want to reinforce it then you are in to the general wing world rather than anything specific to the raven. if you do decide to reinforce you have a couple of options/ there are 2 relevant types of tape. fibre-reinforced strapping tape, and lightweight packing tape. fibre-reinforced tape- this is heavy and should be used for reinforcement not covering. leading edges of the wing - a strip down the leading edge will provide strength in impact. across the span - a strip across the span will reduce wing flex and increase strength covering: if you want to go further you can cover the wing either with lightweight packing tape or with laminating film. a high-performance wing will be covered, but it's not something you need to do to get in the air. covering will improve stiffness and durability, and also makes the wing more slippery through the air so faster. coloured packing tape can be bought from flyingwings.co.uk among others. laminating film from office supplies or ebay. before you attach any tape to the wing you should apply some spray glue so it has something to bond to - it won't stick reliably to wire-cut EPP, which is what your raven is. flyingwings sell a covering kit (i bought one of these to cover my slipstream) - including fibre tape, 3 colours of packing tape, spray glue and por glue here http://www.flyingwings.co.uk/store/product_info.php?cPath=70_129&products_id=794 that's enough to cover several wings. hope that lot helps!

here's a pic of the wing i built for my drone project after i applied reinforcement tape. It's a strip along the leading edge, a cross through the middle and a strap across the span at the rear along with CF reinforcement. The nose is all taped up too. This is a pretty solid setup - it's also then covered in laminating film. I just test flew it on 6s today on a 1600 watt motor, the motor threw a bearing and sent the plane spinning nose first in to the ground at over 100mph. 2 lipos and a gopro totalled, but the plane is absolutely fine - it's already ready to go back up. all that happened was a wing tip came off and needed gluing back on. A properly reinforced wing is nearly impossible to kill! On motor angles - it needs to have the thrust pointing straight through the centre of gravity. So on many wings where the motor is mounted above the back of the wing it is angled slightly down, to put the thrust line through the CoG. On the pic above, the mount is a flat plate in the middle of the wing so the thrust line is straight. On your raven i THINK you are mounting flat to an EPP block in line with the wing rather than above it, so you probably just want to screw it straight in flat.

sweet! what are you going to power them with? I wish i had someone to fly combat with here in hackney. i'd love to give that a go.

i went to all the trouble of soldering the 2212 up, and fitting it, but turns out the prop goes straight through the CF strip I embedded in the wing in front of the vert stab. surgery to fix that is too severe for this time of night reckon i'll see it as a sign that i should wait for the blue wonder and have this as a sedate little thing i can give my boy a go on.. for now at least.

ok so i got it out, flew 1 bazttery, got it dialled in, was flying nicely; unfortunately i burnt the motor out on the second battery. humph. i can either wait for a 1700kv blue wonder to arrive, or i can shove a 2212-06 2200kv on it, which may be a bit overkill........ i'm thinking the 2212.
