Default 10-11 lb Options?

I have an 10+ lb aircraft I am thinking of going with electric and have no idea where to start.

I want to fly scale 1/7th T-28( see my Avatar)

I would love to see ideas on a complete setup, motor,esc, battery...


Thanks
Mike

If you base the requirements on a 10lb. plane, you are going to need about 900 total watts of power to have it fly scale. I would recommend going a little above that, closer to 1000 total watts or so. Watts = battery voltage x amp draw of motor. I would run at least a 5 cell 18.5 volt lipo, maybe even a 6 cell 22.2 volt. If you went with a 5 cell 18.5 volt you would need to run about 55 amps +/- to get up to 1000 watts. If you went with a 6 cell 22.2 volt you would need to run about 45 amps.

Option #1
Motor - HiMax HC5030-390 Outrunner 390 kv
ESC - Castle Creations Phoenix 60
Battery - Thunder Power Extreme TP4500-6SX

Option #2 - Not quite as much power in terms of watts but close
Motor - E-Flite Power 60 Outrunner 400 kv
ESC - E-Flite 60 amp Pro
Battery - Thunder Power Extreme TP4500-5SX

The first option would provide a little more power and longer flight times because you don't have to run as many amps to get the total watts you need with the 6 cell pack.

For higher power needs as you mentioned, I would suggest:
1) expensive but top notch quality: PLETTENBERG's ORBIT XL series, one of the sources I have used= icare of Canada.
2) most reasonably priced but STILL made in German= KONTRONIKs' KORA TOP 20- OR 30- , Tango 45-06 or -08 , i have over a dozen of them, none of them shown any defects, I have some of them used in my hotrods, at insanely abuses, sources=tower hobbies of USA, or Hoellein of German.
3) Economic but with sound/ proven quality= AXI 's from 4130-16/20 to 5330 series....
4) buy cheap buy the cheapiest.....too much on the market already..........Some works great some are not, need lucks...

For ESC, I would go for JETIs Spin series for their special features, or their older gen wrapped in RED = NO BRAINER, EASY to use yet very rug and reliable-----they have significantly better in RF side effects compared to that USA made ESC in my experience


I would highly recommend AXI + Jeti esc , especially you are living in US, because they keep their words regarding after sales services.
Also, I have VERY GOOD impression about those AXIs, the first big BL I owned is a 4130-20 which was bought some 4 yrs and it is still working in good order. But of course there are more cheaper substitutes especially around here, I have a full box of dead motors (from as smaller as a bell motor to the biggest size similar copies of AXI 5330) they are mostly died of burnt at high rpm, poor materials, poor craftsmanship.......

You can get 1200W out of an AXi 4130/16 and a 6S, 5000mAh LiPoly pack with a 16x10 prop. That ought to be more than adequate for a 10-11lb airplane.

I always like to throw a little extra power at planes just so's they can get out of sticky spots.
