Hey all, I've got all my holidays out of the way and have been working hard the last few weeks testing and tweaking and things are progressing well! I'm nearly done with the design, just got a few tweaks to make to finalise some of the hardware (motor mounts etc) and I should be ready to start things moving production wise!

I put together a little montage of some clips just to prove it does actually fly! :P

https://youtu.be/dPenO7UbxnM

I'm hoping to have initial kits ready in the next 3-4 weeks, I'm not taking orders yet but if you think you will be interested in a kit then could you ping me a message or post here (no commitment, just want an idea of numbers from here).

Price wise I'm looking at 80 posted (UK only) for the kit, including:

Full EPP airframe (2x wings, center section and vertical stabilisers)
8mm main carbon spar
6x strip spars
Correx bay covers + winglets
Balsa elevons
High quality control horns
Vinyl decals
3d printed motor mount

It's been a hard process to get here but I'm excited to get this into other peoples hands and see what decent pilots can do with it! :D

Cheers guys, getting really close now. I've got to build this final version and make sure I'm happy with the way it flies then I should be good to go!

Here's a little sneak peak at what will be in the box...

So it was a successful testing weekend for the 'production' version and I'm really happy with its performance so I'll be starting to make kits this week and hopefully be ready to ship the first few next week. I've had to order some more foam for the fuse sections so I have enough for about 4 kits immediately, then the rest will take another few weeks for the new foam to arrive.

I've modified things a little with the vertical stabs, they will now be correx with a 3d printed base. This will sit flush on the wing and gives the correx the correct angle. It means it's easy to swap them out if they get a bit tatty and you could even experiment with different shapes if you wanted to. The foam fins were hard to get angled correctly and were hard to fix onto the wing, I think the correx solution is much nicer, looks better and will last longer as well due to the easily replaceable nature.

So I'll open it up for 'pre-orders' on a first come, first served basis. Send me your email via PM and I'll confirm your place in the queue and send you a paypal invoice once your kit is ready for shipping. Price for you guys is 80 shipped (to the UK only for now, contact me if you're outside of the UK and I'll see what the postage costs are), once I go live on the web they will be 90 + shipping, so whilst it's not an earth shattering discount it's still saving you roughly 20.

The kit contains:



Full EPP airframe (2x wings, center section and sidewalls)
8mm main carbon spar
6x strip spars
Correx bay covers + vertical stabilisers
Balsa elevons
High quality control horns
Vinyl decals
3d printed motor mount + stabiliser mounts

I'll make a detailed post regarding the recommended setup and I'm putting together a build guide although it's fairly self-explanatory anyway.



Thanks for your support guys, I'm looking forward to seeing them get built and flown! :D

Well done, can you give us a list of recommended hardware please? Maybe one for duration and one for hooning?

iwan_canobi, won't let me pm you as I'm a new member.

Any other way of contacting you ?

Well done, can you give us a list of recommended hardware please? Maybe one for duration and one for hooning?

Of course! So there is loads of room for batteries in the front bay and the motor mount can either mount 'outboard' or you can cut away some foam and mount it 'inboard'. CoG is critical though and this frame tends towards being tail heavy so you need to be careful how heavy a motor you hang off the back depending on what battery you plan on using. There are loads of configs you could potentially use, but here are some I've flown with in my testing:

Duration -
1200kv motor (36 size maximum) - 9x6 prop
60A ESC
4S battery 5200mah Multistar will work but depending on motor weight you may need some extra nose weight. Up the battery size to 6000mah or something around 6-700g weight and you will be bang on. The frame and wings can cope no issues with the extra weight, it's just the CG that needs considered.

Hooning -
1800kv NTM V2 3536 with 8x5 prop
80-90A ESC
4S battery as above really

Somewhere in between -
1400kv motor, 8x5 prop

Motors I've tried so far -

1800kV NTM - https://hobbyking.com/en_us/propdrive-v2-3536a-1800kv-brushless-outrunner-motor.html
This is a heavy little beast which has tons of power and is cheap. It's been fine for me but unless you want to add some nose weight then you need to mount it 'inboard' which can cause some heating issues unless you cut a bit more foam away for better airflow. It's easily do-able though. Draws about 50A full throttle but can get a mini drak above 100mph so this will be close to it (I haven't completed any proper speed measurements on this airframe yet, all flights were intentionally on a bare airframe with no AP or flight control).

1400kv NTM 2836 https://hobbyking.com/en_us/propdrive-v2-2836-1400kv-brushless-outrunner-motor.html
I have this on my flyingwings Genesis on 8x4 and it's been fine, I tried it on 9x6 on the E-wings and it killed the bearings after 2 flights so I can't really recommend it too much as there may be quality issues. It's quite light though and on 8x4 has a decent amount of power. More of a cruiser though.

1200kV NTM https://hobbyking.com/en_us/prop-drive-v2-series-2836-1200kv-530w-brushless-outrunner-motor.html
Can't recommend this, it performed well on 9x6 for 2 flights again and the bearings crapped out on me. NTM motors seem to have quality control issues with bearings which is a shame as they are nice when they work and fairly light for the 'claimed' power capability.

Turnigy Aerodrive SK3 1400kV - https://hobbyking.com/en_us/turnigy-aerodrive-sk3-3536-1400kv-brushless-outrunner-motor.html
This is a nice quality motor and has performed well on 8x5 props. Like the 1800kV NTM it needs mounted inboard if you are using a multistar or similar battery so you need to keep an eye on temperatures. Mounted outboard it is totally fine. This is a nice 'jack of all' motor for me, can cruise at low amps and has decent poke when you hammer it.

Turnigy L3010B-1300kv - https://hobbyking.com/en_us/turnigy-l3010b-1300-brushless-motor-420w.html
This one surprised me, it's super cheap but actually performed really nicely with an 8x5 prop. It's no speed demon but the earlier video I shared uses it so it has a fair turn of speed still.

Turnigy SK3 1250kV - https://hobbyking.com/en_us/turnigy-aerodrive-sk3-3542-1250kv-brushless-outrunner-motor.html
This is a really nice motor but it's pushing the weight a bit. Consider this if you are putting bigger batteries in. I plan to test this one on 5S with an 8x6 prop for some super fast cruising. Runs on 4S with a 9x6 without breaking a sweat.

In terms of servos just get something with decent torque. I've been using Turnigy 2.5kg torque 13g metal gear ones which have been fine.

Heres a little unboxing of the kit one of my beta testers has done -

https://youtu.be/6bDlTJ-FPxA

Just a reminder - ping me a PM if you want a kit! Will be shipping next week for the first few orders and I have a few in already.
