Motor query for a hornet

[bugged]

Mangaged to get my super hornet up and running ( Whoohoo ) Its has a 540, Lrp f1 esc and a tamiya 1400 ni cad.

Im looking at either a 15 single, Or a 15 douable motor for it. Im right in thinking that single winds are more punchy. And the more the winds there are the smoother the power delivery is ??

What is the hottest motor that you guys run in your hornets ???

Cheers

I'd say a Super Hornet with a 15 would be totally lacking in handling! Also the 1400 battery would give very little run time and you wouldn't be able to gear the car to suit the motor. I would try a 27 turn stock motor like the Trinity Revenge of the Monster as you'll get a good power boost while still having a half decent runtime and some controllablity.

i ran a 13x2 in a hornet but kept braking the diff case id prob stick to a good 17x2 nexttime as it does get rather anoying changing diffs every time you run it

Lmaoo @ lacking in handling! Like it has anyways. Put the power down the front wheels lift, And dont steer [] I have had it pulling wheelie [xx(] [] If i was looking for a models that handles, If certainly wouldnt be a super hornet. Or any i.e. Hopper or hornet. Its all about about fun, With a smidge of handling ! Probaly best if i spend the money on getting a 3300 ni hm cells for it, and maybe a 20 single, Or douable....

Sounds like my monster beetle, With a twelve single !!!!! Then again thats was years ago, When you could order a gearbox and have it a day later...

I have been running a LRP GT1 17X2 in my Hornet and its super quick!

[DCLXVI]

I've ran my Grashopper with a 17x1 and that was loads of fun so I say go for it...

Might be a problem with that battery though...

Back when, I used to run my hornet with a 13x2, with a ballraced gear box. Never had and reliability problems, just couldnt drive the thing.

Ended up creating an LSD by adding rubber rings to the pins holding the 3 bevel gears in the diff, with a touch of grease. The tight fit limits the diff slip and it helps make the thing go straight.

Acorn that LSD idea sounds like an idea to try, By little rubber rings, u mean the little ones that go in the bottom of cva shocks as have a few of them floating around in my spares box....And im running a 1700 ni cad pack, Not that it will make alot of difference []

[bugged]

Box stripped and rebuild, With the addition of 3 rubber rings on the bevel gear pins ! Just had a quick run and its works [8D]

13x2 Here i come [] And a new pack of cells [:I][]

Thanks

Bugged:

Glad to hear it worked.

I honestly cant remember which rings I used, could well be the ones you used. I still have the old Hornet, I might strip it down and see what I used.....if they havent completely died!!!!

All thats needed is to add some friction to the bevel gears, I reckon a 2-3ish mm length of IC fuel pipe might work if no rings are avaliable.

[bugged]

i used the rubber rings that you use to put in the end of the drive cups in most tamiya cars. They feel alittle tight. As the diffs is almost completely locked. Is this how yours was ? I have given it a test run with a 540 in. And it seems fine, And steers asper usual []

was yours pretty much the same, I mean the diff being stiff..Almost to stiff ??

Cheers again

Nice idea, wonder though how long those rings will last the wear, especially with the gearbox grease [?] Btw a very stiff diff wouldn't be good for a Hornet as it would merely work on such a light and low grip car, maybe remove 1 or 2 rings or use some very thick greas instead??

Cheers

[acorn]

The rings lasted ok, but I cant really remember for how long. As for how many rings, experimentation is the name of the game. An alternative to the rings(correctly identified as the ones that go in the drive cups, I remember now!!!) is to use 1-2mm lengths of fuel pipe drom an IC car. Never tried it, but that might work better, and allow fine tuning of the diff slip.

I must strip down mine and see what I actually did!!!

[acorn]

Forgot to add, although it should be pretty obvious.

Use ball bearings in the gear box. Not just for effeciency, but bearings will place the large bevel gears more accurately on the diff. This should reduce the chances of killing the diff.

Update:

Took the Hornet gearbox appart, and although I found NO rubber rings, I did remember and find the rubber rings I used. They are the ones found (and I know its obscure) are the same as the rings used to mount the Avante shocks to the double ball pins at the top. These are bigger than the rings found in the cup joints.

Hope it helps.
