Another new heli from Blade...B300x

[ukpaul]

James,

How does this fly with a lower head speed for the average sport flyer?

I'm tempted to get one due to the small size (loving my MCPX) but not being a 3D whizz, don't feel I need the high (seems high to me) head speed shown in the vid. Was hoping I could fit a smaller pinion for less head speed and slightly longer flights, just zooming around doing basic loops, stall turns and flips etc.

Also you say it flys 'light', but is this because of the highish head speed? If the head speed is reduced a bit, will it feel much heavier all of a sudden, due to it's suggested highish weight for it's size?

BTW in the manual it does appear to list the pinion as 9T, with a 10T as an option, while you say standard is a 10T. As I'm sure your correct, this would make the manual wrong? Was hoping I could go down to a 9T or maybe 8T if the standard one is a 10T?


Paul.

Just looking at the specs...

Gross Weight: 17.3 oz (491 g)
Rotor Blade Length: 245mm

The Gaui X2 FES has 255mm blades and weighs only 360g. Only $599 inc 4 servos & BeastX. Mine runs rings around my 250.

According to this link, the X2 weighs 334g but NOT including battery

Can you confirm if your quoted weight of 360g includes the battery? That could be the difference

Hi Guys,

I just wanted to clarify the pinion options.

I messed up with pinions I posted earlier. I had the 450 X on my brain.

For the 300 X the 9t pinion is stock and the 10t pinion is optional as well as an 11t,(Carbon blades must be used with the 10 and 11). Again, I apologize for the confusion. I am getting the gear ratio fixed online, stock gearing is 15.5:1.

@ukpaul
Thank you for catching this I was actually in the process of fixing this when I saw your post. With the 9t a sport flyer will love it. The headspeed is very low for a helicopter this size. It flies extremely well at this headspeed. I don't believe we have an 8t available but turning down your throttle curve to 80% or 70% will give a nice flight time.

Thanks,
James

James can you confirm that the 491g includes the flight battery (I assume it does)
I suspect that the Gaui X2 quoted weight is sans battery

A typical 1350mAH pack weighs in the region of 120g, This brings the weight into the same ballpark

The Trex250 had a flying weight of 330-400g but it has a considerably smaller disc size and narrow chord blades


....do I get a free one now?.....just joking, or am I!, It's about time I was a Blade test pilot

[ukpaul]

Thanks for the quick reply James and the stock pinion clarification.

So your saying it's setup more as a sport flyer then out of the box, as it comes with a 9T? Am I understanding you correctly?

Upgrade to a 10T or 11T with carbons if your a 3D stick twiddler?

[merlin3]

Yes the quoted weight for the 300x is including battery and everything and it comes with 9t pinion installed which will do 3d just fine as well

I just weighed it again. See attached photo below. I picked up a few grams somewhere, probably from the new canopy balanced on the boom block. This was one of the first Gaui 255 kits that came with just motor and ESC. I upgraded it with X2 parts later. The components I'm using are quite light. The battery is only a 25c 3s 1000mAh but it's good enough for 4 mins with the headspeed I'm running, only about 3700rpm. MiniVbar (11g) vs BeastX (17g). Cyclic servos; 3 x Futaba S3157 (8g) vs Gaui GS-093 (12.2g). Tail servo; Hyperion DS11GCB (10.3g) vs Gaui GS-095 (12.2g).

I usually build my helis light. My first T-Rex 250 (flybar) weighed only 293g compared to 340g in stock form. It made a big difference in performance.

Sorry I don't mean to Hijack this thread about my X2. Just answering your question. I am interested in the B300X really :)

Thanks for doing that, that's very impressive to keep it that light. I can't image where the extra 100 odd grams comes in

Hi guys,

I just wanted to confirm what Justin (Merlin) is saying. I double checked the weight again today( you had me worried I got the weight wrong...) The weight is correct, 491g. I assure you it flies very light though :)

Thanks,
James

I'm definitely in... pre-ordered - so please don't disappoint!

I've been thinking of a heli this size so I've chosen this over a slightly smaller T-Rex but just wondering as well where the mass is, in comparison to a slightly smaller T-rex 250. Bit more mass is probably good for me, I suspect, so long as she's stable and has enough juice, which she appears to have.

So stock is about half a kilo. Some of it must be the (wooden) blades. Or apparently thicker tailboom/plastic fins?

What happens if we dump the woodies for CF?

The Align BL250SP motor weighs 32g. I would expect the B300X motor to weigh in around 40g. The Align 15A ESC is about 15g. I would expect the B300X ESC to be stronger and weigh a few grams more. The Align DS410 servos are way overkill at 13.5g, so I can't see any weight increase there for the B300X.

I think the Achilies heal of the T-Rex 250 is it's setup. Mine flies like a charm but it took a lot of trial and error to get it the way it is. If the B300X will fly like it does in the video, right out of the box with no mods or tweaking then it will be a winner.

@spykez

The wood blades are spec'd around 18g they will obviously vary slightly. The carbon blades are spec'd around 15g and they will very slightly as well. So you can save 3g by switching :D

Thanks,
James

[jrod155]

i had an X2, the belt was terrible on the stock pulleys and it was all around too fragile. I had a trex 250, that thing is a piece of garbage, i stripped screws all the time and it was a pain to work on. I crashed both of those helis twice, each time was because the tail let go.

I'm really glad to see basically a 450 tail on it. Thrust bearings should make a huge difference.

I really wanted something all plastic, this is perfect. I've pre-ordered.

maybe this will convince edge to make a 250mm fbl blade now.

[honkytown]

<-- sold in the 1st minute...preordered and hopefully be satisfied :peace

one question on the flytime, cause in the specs (http://www.horizonhobby.com/products/blade-300-x-bnf-BLH4580#t2) u mentioned a 1350mAh 3s lipo and a flighttime of 4min, but in the 300x manual ger/ital/fre (http://www.horizonhobby.com/pdf/BLH4580-Manual_DE.pdf) you talk about a 2200mAh 3s lipo.

so which one isn't up2date?

some other differences in the manuals are:
main rotordiameter 721mm vs 550mm
tail rotordiameter 155mm vs 140mm
weight 717g vs 491g
length 655mm vs 510mm
height 225mm vs 195mm


can someone enlight me? looks like an evil copy&paste party gone wrong :DOH

LOL, ok. I expect the woodies might be badly balanced like the B450 3D ones, so I hope your CF option will mean less work. I'll probably swap them at the first instance for the higher head speed tolerance and hopefully better balance anyway.

Please, please James, just let your logistics dept. know not to screw up this release ? :rotf

[kwesty2008]

I was really considering a Heli this size, and the blade looks good.. But pit it side by side with the Gaui X2, I'd go the X2 hands down..
Ok, the blade has the 7200bx, but the gaui has
-CF blades not wood
-metal grips not plastic
-pretty sure it comes in TT or belt
-personally looks better
-and has beastX anyway..

So really, the blade is really overpriced. Ok, it's BNF, but I just can't justify nearly $700 for s plastic Heli..

Where did you get $700 from? The list price is $399. The AR7200BX would cost you $240 if you bought it seperately, so that means you're getting the airframe, motor, Esc and servos for just $159. I think that's cheap :thumbup:

[GravityJunkie]

The Blade BNF is not $700.

[merlin3]

also don't get caught up in some parts not being metal. Sometimes composite/plastic is a better option not only for cost. Take for example a trex 250, it's almost all metal but it's all crap metal and it flys horrible.

Agreed, also I was looking at the pics and the only piece i want non plastic is the swash and it looks like its aluminum on the top but its black on the bottom... so what exactly is the swash?

Other then that ill probably swap out the plastic pieces with cnc as they break as long as it doesn't affect the performance because I like bling + stronger pieces for crashes.

[soljkaer20]

@ Honkytown

Thank you for catching this issue with the specs and components. We are currently getting this fixed! The correct units are in the English portion of the manual. The battery is the 1350mAh. Easily capable of 4 minutes.

As for the price the 300 X is MAP'd at 379.99 well below $700.

As for the logistics I feel very confident in the April release. As for the optional metal parts they unfortunately will not be avaiable right away. They look like they are going to be 3-4 weeks after. I apologize for this but we are working very hard to insure that there are plenty of spare parts! :thumbup:

Thanks,
James

Totally agree. Plastic/composite parts make sense - they keep the weight down and are pretty durable. The proof of a good heli is how it flies. If it flies good - it is good. Look at the new Boeing 787 Dreamliner - it uses composites big time in its construction. No metal upgrades here!

[chardur]

Ya, I dont know where the $700 price came from. The member price at my hobby store make this even more reasonably priced. I can pre order for $325. I bet other hobby stores will offer this below the $379 MAP price.

[Ampdraw]

Ran some numbers.

My Gaui 200 is 246g no lipo and 296 with a 2s 800mah and has 440mm disk

The 300X has a list of 490g incl lipo with a 550 disk. Even with a lighter lipo the disk loading is going to be alot higher than my Gaui.

Bummer...liked the idea and simplicity but seems I'm better on the platform I have already for my needs.

Since this thread seems to be a direct link to those in the know are there any interchangeable parts with the SR?

[InFocus]

hehe, they can both use the same TX.
