Scratch build 37" Mono Vids

[F1 madness]

Well got my new 3026 scorpion 1900kv motor and new 120amp esc today and installed them.
1st run was running 42mm cf prop on 3s,1p,3700mah,25c lipo.came in cold

2nd was using 45mm cf prop on 3s,1p,3700mah,25c lipo.came just warm to the touch

3rd was using 45mm cf prop on 3s,1p,3700mah,25c lipo.came just
Slight adjustment to stinger angle

4th run on 47mm cf prop on 3s,1p,3700mah,25c lipo.came just abit warmer but picked up some weed round the prop so called it a day and batt was running low.

Hope you like,im well happy with it cant wait to get some 4s batts

looking good there daz, 4s will perk it up some,do you have any timing on the esc ?

[F1 madness]

no just used the esc staight out the packet LOL.
not sure how to set it i got to go through the instructions.
probably a stupid question does it make much difference,still try to get a grasp of this brushless malarky

[ozzie-crawl]

yea it does,when i first tried a 3026 in my cat it really came to life once i put 15 deg timing on it.before that it was a bit sluggish

cheers bud
i'll have a look in the morning,time for bed now LOL

[ozzie-crawl]

what at 10 in the morning lol
okay its 1 am were you are

[F1 madness]

what at 10 in the morning lol
okay its 1 am were you are

morning bud
will have a play around today and see if i can work out how to adjust the timing and see if i can get it back on water and see if its any better.
does it make much difference in temps

[ozzie-crawl]

yea i would watch temps but i think its more efficient at 15 deg so may run cooler

im gonna get me temp reader of sum sort so i can monitor the temps properly,but will give it whirl,ill run it for 1 min and see what its like

[ozzie-crawl]

just done some quick fe calc and with a 47 mm prop (assuming 1.4 pitch) 3s
if you run 4s with 442 your amps should be close to the same but speed should be up by around 7-8 mph
i ran a 642 on mine

Ok,once i get new 4s batts ill start with smaller prop (42mm) and go from there.trying different set ups and checking temps etc as i go.
but will keep you posted on progress and vids.
