These are my videos for the new Arrows RC Viper 50mm EDF Jet.

Unboxing & Review:

Maiden Flight Review:

Review Notes for this Arrows Viper EDF Jet:

Pros:
- Looks great
- Plastic nose cone for durability
- Grips for easy hand tossing
- Fantastic value price, check links in the description!
- Powerful 50mm EDF unit
- Three plastic skids on the bottom
- It handles very similarly to the E-flite Viper Jet
- Designed for 3S packs so you can get a lot of packs for hours of fun without breaking the bank.

Cons:
- I prefer all screws to any glue, but it wasn’t bad overall.

I would assume this Viper will be similar to the Skyangel 50mm T45 ... which I have two of.

CoG is of course set xx back from LE of wing ... but when I modified mine to have 5000kv on a 5blade - I put in a 1600 4S pack ... CoG ended up on the LE where it joined fuselage. I thought ... yeh yeh yeh ... this will be a disaster. In fact it hardly changed her at all - but BOY what a flyer !! 

I tried a smaller 4S in her but flight time was too short ............ 

Original was 4300kv on a 5 blade ... with factory spec 800 3S ........... total crap !! It flew but an 800 was just gutless. I put in a 1500 3S and it became a hot flyer .... and then the Need for Speed group was running on Wattflyer and along with my Parkjet - it was into 4S .... 
I pushed the limits of the T45 in the end that I used a bungee to get her in the air ... especially when I put the heli motor on the back end of one with a 4.1 x 4.1 prop ..... INSANE !! 

AS GBL has found in the Viper - these 50mm EDF's are a very nice size ... fly well ... we just need more !!
I'll fly anything if I can launch it ! Youtube : solentlifeuk

Thanks for that Solent,
Not a blisteringly good recommendation, as I thought it might be gutless, and boredom sets in very quickly for me when I aint 3 feet from the ground at 50mph,
so with your plane in mind I'm gonna build my own edf from T38 plans I have, it's for a pusher prop but should be an easy modification.

The problem with these 50's .......... the recc'd batterys are small to keep weight down ... They cannot feed the amps needed to get best out.

Here's the T45 with the 1800 in her ... I'd flown her with the 800 but UGH !! (apologies - I wrongly said 1500 before)



Here you see she's a hot flyer and very good ... 

Later with 1600 4S, 4300kv  :



Then the 5000kv is in :



She basically hits the speed wall and would take massive power to break it .. 

My other with pusher prop if you really want adrenaline !



Which manages to push past the speed wall and hits insane level !!

The the pusher prop is great in theory until you launch one without a catapult and it's spins like a bullet, usually right into the ground after about 3-4 seconds of flight time, I'm not a fan of them.
however yours does look and sound fast. ðŸ˜‰ðŸ‘

Hi Solent,
Seeing as I do not have a launcher and I'm deperately diasappointed in my rear prop pusher F15 Eagle with all it's incredible torque roll, "see crashed and broken" for an accurate description of disappointed, I have started building a twin motor rear pusher prop J20, now that should get rid of torque roll, counter rotating, got a question for the fliers on here who have built twin motor planes, both motors rotaing in towards the plane or out ??
or does it not make a blind bit of difference .

In as a rule on tractor but as a pusher I don't think it would make any difference.

Still fully flyable today ...
