Rave MS Hornet, the die hard micro, thread 1

> i've never heard of a hornet stock breaking in flight
I'm thinking just in case with using old style blades or even wood.

Ah I see the what you mean... You could try a two part mixable glue instead of brittle CA type glues and try removing the shaft to scuff n rough the shaft surface area where the gear sits for a better glue contact. Or like you suggest, a thicker spacer tube. You could trim the spacer and use the old part of the gear collar re-attached around the other side of the original gear.

> thinking of going to 4s 1320
4s should do the trick and would be worth a trying but that means a new ESC and/or separate BEC. Sadly I haven't got a great deal of funds to experiment .

I think the MS controller is perfectly safe on 4s (not the bec though that needs be to a seperate one) seeing the FETS are much bigger than on phoenix 10 and even that has been usedon 4s.

I just hope the controller does'nt have a very low RPM limit!

If the gears are slipping on the steel shaft i think they are stretched...the carbon rods sometimes weren't big enough and you had to use some retaining strategy (glue, pin through hole) but if it's the steel shaft i say just buy a new set of gears...they should be snug. I use a little green loctite.

On my newest hornet (one i got from a friend for helping him out with his trexes ) i couldn't even get the small pinion completely over the shaft so i had to use a piece of heatshrinkbetween the pinion and the bearing.

The heli is a Hornet1. Started life as a FP.
The steel shaft is part of the Microheli tail case. They describe it as being made from "High Speed steel"
The gear was new and was a bit loose right from the start.

Bit of fun , Hornet owners world map. Are you on it?

[muscleflex]

was going thru my hornet last night and find out that an HS50 servo i thought was burnt out still works!
so i think i'm still in line with completing my hornet 1! i also have the carbon blades for it..
just need to dust off that lil PG03 gyro!
by the way - can i use the lipo batteries off a lama 2 on a hornet fp? instead of nimah? i think my esc is a jeti 3 (or 5) amp...don't exactly know what model it is...

[muscleflex]

was fiddling with my hornet tonight...and managed to get the receiver working still! phew! i was hesitant to plug the battery in as i've burnt 2 receivers in the past, plugging them the wrong way around...it's the GWS 6n naro type!
but - i just realised what i am missing...a crystal for my transmitter!!! i remember the original 4ch futaba transmitter i was using for it got stolen and i guess i never replaced the crystal as that's when i lost interest and never fixed the hornet..so i'm looking out on ebay for the right crystal! i need a 72ch single conversion

Good work muscleflex , not sure about the batts, what spec are they, 2 cell?

I found 2 Hornet video's demonstrating some good flying skills that are no longer hosted anywhere, so I have uploaded them to some cheap webspace. I think the download speed is restricted 50k/s max, don't be surprised for example if 10 people pulling only get 5k/s each. Apparently no bandwidth limit, hence the speed restriction.

Heliup belt drive conversion with a modified Hornet X-CP (not CPX as it claims):
Hornet-X-CP_modified_plus_Beltdrive_Heliup.wmv 12MB
A shame you can't hear what the rotor is doing under load.
Details here and here.
I don't think it ever got from being a prototype to a product.

Spinout chucking his modified Hornet 2 around the sky:
HORNET_2_0003_Spinout.wmv 19MB
Twister, 13T/88T Duzi main gear, 3xTP1320mAh, weight unknown

Only it looks like Spinout was cursed with a simular camera that Mattijs currently uses .

Anyone ever stretch a Hornet bigger than a H2 or X3D? I've got most of a Hornet FP and a CP conversion kit, and I'd like to rebuild it with a longer boom and Maxir blades. I'm guessing I'd need to use a longer main shaft to prevent boom strikes, and my old FP tail rotor doesn't have bearings, so I would need some new X3D tail parts.

[DarkHorse]

A good selection of stretching and belting up related threads collected:

Stretching option:
Boom: Gold Tip XT Hunter Hardwoods Arrow Shafts 75/95 £6.24 UK
O.D. 0.300"/7.62mm, I.D. 0.246"/6.23mm, Length 32"/813mm
Shaft: ~$5 Y0175 - MaxIR CF tail drive 2 mm x 355 mm


Mattijs debates some good points here:
Discussion - aplus, why not stretch it to maxir size?

MaxIR:

[mattijs321]

say darkhorse, would you fancy trying out the 450th?

I will in the end get one no doubt, possibly on a hornet maxir hybrid, but right now i don't even have the time to fly.


How are you're flying skills at the moment?



I have had some luck my last flight....i noticed that the power wasn't where it usually is but i didn't mind and just kept flying....suddenly the heli just stopped responding and dropped down....luckily i just came back normal after a long inverted stretch....landed on it's feet all by itself.

Reason was on of the wires on the ESC had been getting thinner and thinner from BENDING it too much (eventhough it was quality wire).

I got it repaired and it has much more power then before, atleast with prolites 1320, the old TP's don't cut it anymore...maybe because they are old buit probably mostly because with them the heli weighs in at 384 grams!!!


Not that that would be a reason not to go to a more powerfull motor.



BTW i've also been thinking about the 430f align motor, it's as cheap and as light as the 450th but it might be a tad more efficient and it probably will turn out as powerfull as the 450th on a setup that can't give both the current they need to get even warm.

Darkhorse...
i think it's a 2cell lipo. probably 700mah. didn't want to burn my receiver so i left it at that. i did plug a receiver battery from my nitro car (4.8v) and it worked! so that's great! i think i will take some pics tonight and maybe put a pic diary of my hornet till i get it all built up and flying again!
the one thing that's really stopping me is the canopy! it got crushed when my tv fell on top of it (when my flat got broken in) and i don't know if i can still get bodies for it...
my local hobby store has a hitec ch72 so i'll be picking that up this saturday! i'll post a pic of what my hornet looks like at the mo tonight...

thanks for all those links, darkhorse!

if you want a canopy fast....get a x3d one....it comes with some stickers on it (which i take of) but most importantly its very light AND comes assembled like on a trex!!!!!

That place has some fiberglass tubes that are pretty close in diameter to Hornet tail boom.

would that fit the original hornet Fp?

[DarkHorse]

If you power the 'jeti 3 (or 5) amp' with the 700mAh 2 cell pack (7.4v), plug the ESC into the Rx you should be fine. I was worried the it was a 3 cell (11.1v) which will work but has been know to eventually burn up the ESC, probably the BEC. I guess you also have a Speed300 type brushed motor on that FP, which will suck the life out of the 2x700mAh pack and may not fly for long before the cells fade under load, if the fly at all. A 3 cell pack gives the FP some juice, especially outdoors in FF. Only $10 for a smart looking ready to go X series canopy, should be able to fit a H1 with improvised servo tray spike mounts glued in place.

H1, CP, CPX:
Boom = 280 mm x 7 mm, Outside diameter is 7.0 mm , Inside diameter is 6 mm. ?not sure?
Shaft 293x2mm CF

H2, X-3D, X-CP, X-FP:
Boom = 320 mm x 7.5 mm , Outside diameter is 7.5 mm , Inside diameter is 6.1 mm
Shaft 333x2mm Steel ?not sure?

MaxIR:
Boom = 335 mm x 8 mm, Outside diameter is 8mm , Inside diameter is 7mm.
Shaft 355 mm x 2 mm CF
