Looking like i'm heading in the direction of the scorpion that WarMachine posted..
hk 3026 1900kv,5s,27043rpm,130a,7x10....not to sure wether thats static,logged in flight,or prop calc?

Except i'll be on dup's 6x10's so amps will drop abit,mayb 120a? Also can source motor in n.z and at $140nz its cheap..
The other motor i could consider is the mega 22 35 1.5er,but its 50g heavier and dunno if it'd give same performance? can't find much data on it.....and the more you chip at that throttle,the more the esc and lipo start to dislike you ; )

hmmmmmm
You had posted that you want a "good all around plane" if that is the case,i would go 1600Kv on the Outrunner with the 7X10 folder on 5S.....1900Kv would be good for speed runs in burst,and that is about it.

Apc 5.25x6.25

I forgot all about this graph which I made 2-3 weeks ago.

.....Not so sure that the limited battery room on Swist will allow that many Watts during high speed passes....remains to be seen.

Static data from 1 second after the peak AMP spike.
%KV under load was looking pretty good, I ran out of cell count so I could not fully push the 28mm MEGA motors for the short duration.



Good luck to you all,

Gryphon

Pushing anything to it's limits is a rush for sure....but at the end of the day,your chances of coming home with some messed up stuff is very high....after playing with a bunch of powertrains i soon found that with these go-fast elec missles,it is MUCH WISER to find a system that works without trashing equipment if you plan to sport fly a bunch (setups that can only run for 15 to 30 second bursts can be a Pain in the Nutz some days),and that can be pretty hard when you think with the apendage

It may snd strange,but this is my first full carbon etc airframe,when you talk about epoxying the stab/elev to fuse-are u just using standard 5min & 30min epoxy? I always thought you had to use a special carbon type glue..?
Get any flying in today? cheers

Standard 30min will be fine. I rough up the saddle and drill some small .5mm holes into it so the epoxy forms these small 'epoxy rivets' helps hold it on. I've only had a tail let go when it went nose first into the ground at 300k and then caught fire

I use Hysol for motor mounts and then reinforce the front of the firewall with carbon rovings and laminating resin after the hysol has cured. I also then put the whole thing in an oven at 50 degreesC to finish the cure.

Ive never had a problem gluing mounts with normal 30min epoxy, but just be aware as the motor heats up the glue will soften. That's why I tend to use rather exotic adhesives for motor mounts. Never had a firewall pop out (:

A few things to remember,there is a big difference between a setup that can only run for 15 seconds and have to get off the throttle before things start melting....and flying at 15 seconds burst on a lower power system and you are just stretching the flight ....but in the end,on a FAST plane,i feel both of those are no good.......I have smoked 2 ESC's just cause every time you get on and off that throttle,the ESC starts building heat at every hit,and we are talking 20+ degrees every hit .

What Slowbarless says,scuff and 30 min epoxy.....When i did my mounts,i also use 30min epoxy with no issue,but i do also notch the edges of the mount (in my mind that will help keep them in place) and i also put a bead of 30 minute epoxy mixed with magic carbon fiber dust around the outside as a blocker.....and yes,Got 3 flights on my Swist today,and 2 on my X ....On a side note,i am not to happy with my new Gens Ace Lipos Time to go back to what i know,Thunder Power 65C.
