Post your Hurricane 550 flight videos here

I think with some simple frame mods we could fit 6S 3300-3700 cells. It may involve redistributing the electronics and maybe moving the servo to the boom in order to get the GC right but I think its do-able.

are you kidding me? Betwen bob, you and the rest of us their is so much talent we could build our own heli company, lol.

everything is possible thru desire and ingenuity. and bob. and rh.

Yea some stuff needs to move around. 6S 3300 might be the ticket but there goes the disk loading. I wish FP had something at 3000.....

Bob

[readyheli]

they do at 3200, ;-)

ill let you know how we get them to cg and what kind of flight times bob.

[Finless]

Those are the 30C packs. The 30C packs are heavier in relation to the 25C packs so you know. They are also almost $300 for 6S vs $200 for 3300's!
Yes let me know and if they are good I will get some but I think the 33's will be a better fit.

The Hurricane is still really light.

The weight diff between 2 Flight Power 2500 3s packs and a 6s pack of Flight Power 3300's is 97g (3.4oz). Thats not a lot of added weight.

I think the larger cells current suppling capability would actually improve performnace.

If we can figure out a 5s setup then you are at a 30g weight increase...thats nothing.

I am thinking a Neu 1512/2Y (1400kv) could run on 6s with a 18T pinion and RevCo gear (2500rpm Head Speed) or 5s with a 22T pinion and gear at the same head speed.

[AdrianM]

John - Although the Evo 30's are lower capacity they are bigger heavier cells. The larger size is all about lowering the internal resistance so they can dump the big current without heating up.

The 6S Evo 30 pack is 600g. An Evo 25 3700 is 564g and a 3300 is 515g. 2 - 3S 2500's are 418g

[readyheli]

i know but we are killing the 2500's...we want to go up in headspeed and try the 23t pinion, but not at the expense of losing another minute...thoughts?

[AdrianM]

The 3300's are the lightest and will get you 25% more flight time. You have 3700's in your shop those might be worth a try too.

[readyheli]

are 3300's still avail from fp?

[AdrianM]

I don't know...I just buy stuff...you are the guy with all the connections...lol!

I know Thunder Power still sells Extreme 3300's (same cells as Flight Power).

[Finless]

Yes 3300's are still available!

Hmmm I have some 4,5, and 6S 3700 packs.... 4S wont do as that flew the Lepton for 5 minutes. I used 5S and 6S 3700 on my swift and 5S got me 5 minutes with the 600+ motor swining 550mm blades. It;s mounting them thats a problem unless the frame is modified.

I also feel 3 oz isn't going to effect this heli too much as it feels pretty light for the rotor size, although I'm not sure what Johns weighs. If it becomes a problem we can always custom fit 9650's (should help with CG issues as well) or 550mm blades...or both. I did some research and FP has some very light cells available with a decent 18C discharge rating,

http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXRVT3&P=7

Two of these wired in series would weigh in about the same as 3200's. They have a lower discharge rating but are capable of 76 amps cont vs 62 amps cont for the 2500 25C cells. I think this would get finless his 5 minutes of HARD 3D :twisted:

[Skaross]

2 x 3S3300 is easily viable with little or no modding to the chassis. I just added a plate to the bottom battery mount to take the longer length of the 3300 cells.

It runs from just in front of the foremost skid, along the bottom chassis sides and touches at the front-most point of the existing bottom battery area. There is a small triangular gap between this plate and the existing area intended for the battery.

As for CoG with heavier cells... easy! Take the tail servo off the chassis, and P-clip it to the boom. Just move it back to get the CG right and then make a push-rod to suit this new position. A few $ of parts to get P-clips... Swift ones work, and I expect TR600 will as well.

10S A123 anyone? shotgun config strapped under the heli between skidds? or is the frame wide enough to fit them side by side?

My logo 10 runs 10S with almost 12 minutes of flight time, Z30 800 a and CC45HV,

10S is 33.3 nominal, 36volts full cap, and sag to about 26 volts under load.

They weigh the same as a 6s1p 4900 and if mounted under can be maneuvered to CG correctly.

Another test from Chris flying this afternoon with the Revco gears and pinions. www.hurricane550.com


hey where do you guys fly. im about 30min south of the Readyheli store.

[readyheli]

top secret. beyond those trees is tiger woods house.

its jupiter island.

[arclite5]

Sup WCC. Sometimes Chris and I fly at Tradewinds..

im about 5min from tradewinds park. i live on lyons road between sample and copans road. i usually fly at gerber park right across the stree from my house. 2 soccer fields and a basrball field.

Hey Soccer DAD....I am assuning Justin is your son?? Anyway he is awesome and I look forward to watching his vids so post away :mrgreen:

PS. THe soccer dad comment was because of another post I read that some people called you a soccer dad for posting his vids. They are nuts :noteworthy

[prollegbg]

GAUI 50A ESC ! :) 300 flights, no problems and not broken....
Z-power Z30 - 1100KV
16T piniong and GAUI HP gears (With the OK on them) - 100 flights and still not broken!
A123 - 7S - "Hurricane special edition" 2300mah
MS Composite 515 carbon blades
Headspeed : 2450 (measured)

The power is amazing with this setup... The only downside with A123 is the short flight-times, however there are many many advantages with A123... It´s wonderful to be able to empty the packs without worrying about puffed packs.

(Sorry for the quality)

[Finless]

Lookin good and very powerful. Yes 3 minute flights arent so good though.

Thanks for sharing!

There a recently added vid of little 5 yr old Justin Chi on rr from the IRCHA 2007event. (rr i know but still)

Vid is here, scroll down a bit and look under Sunday, Vid called: Justin Chi - Electric 550 - 55mb Video
http://www.runryder.com/helicopter/rrTV-Photo/funflies/IRCHA2007/ Not sure if the link will work as rr keep messing about for some reason.

Man that kid can fly !

[Fredrick]

why did this thread suddently change into a discussion about mods, rather than videos posted by hurricane 550 pilots???
come on guys post your fligt videos here and show the whole lot of them how well you can fly your hurry:)
So post you footage here FREAKS!
