I have three of these motors , what do you think about at 20/10 Prop ? Was going to run a three blade on my seafury but trying to keep my overall cost down on the spinner , seems like the range from these post are anywhere from 20 and above on 10 cells , 120 HV esc
Product reviews for;
HXT 63-74 200kv Brushless Outrunner (Eq:5240)

Amazing !!

I ordered this Motor, using the latest ratings as source for selecting this piece
for my Jodel Robin with 2,2m and around 9kg weight.This is a electrical " Rocket", absolutly great.Pushs a 20*10 Maro over 7000 rpm,thats about 10kg or 22lbs of thrust at 75Amps on 12S lipos.The motor gets warm, maybee 50 deg c, after 4 to 5 min full power..thats it.
Great Motor, great deal....keep on going !!

Testbench result:

Lipo: 9s2p 2200ma Hextronik (4s+5s Pack as 2P)
Speedcontroller: OEMRC Sentilon100A HV
Prop: 24x8 MenzS (wood)
Voltage under load: 31,4V (measured after 90s after starting the test)
Current: 60 A (at 80% throttle)
Rpm: 5250
Pull: 9,1 Kg / 20,2 lb (measured with digital balance)

All Measurments at 80% of throttle (60 Amp's) because the current capacity of my shunt is only 60 Amp's.

I have Pull of 10,5-11 Kg (only very short measuring 2-3 seconds without current control) without shunt at full throttle.

A well made and very powerfull Outrunner !!!

I am thinking on mounting this brusless outrunner in a smaal electric scooter and the motor looks realy nice good bearing and thick wire from the motor! I recomande every one who buy this motor to buy the recomended esc on 100A whho you can see below the motor information.

A 20x10 should be just fine on that motor on 10s.

Ive got a couple of the old HXT 6364-230kv motors that I run 20x10 turnigy type E wood props on with 10s

Looking for experienced advice

Hi guys, last 2 months I look for ESM Lavochkin la7, one of my favourite birds...

http://www.esmmodel.com/inc/Enproduc...?productid=203

I have free eflite 110 motor, esc 120a HV, and 3 packs 10s 5000mah battery, it is free without any kit...
I guess it is little underpowered but want to now is it enough for safety flying, or thinking about gas engine?
All advices are welcome...

An e-flite 110 motor is not rated for 10s. Its an 8-9s motor. That LA-7 is an 80" plane and a little big for the 110. An e-flite 160 on 10s could fly it, but it'll be a bit sluggish. The flying weights ESM gives are always low. That plane will probably weight over 20 pounds when finished. You'd be better off using a 50cc gas or 50cc electric motor.

Electric looks like more of a PITA when you get into these big sizes. I'd go gas if you can stand the sound of it.

piper is a high wing plane , will float and lift easier then a warbird , what airfoil do you have on your piper ?
I never seen an ESM at that size on a 110

Nah. Easy as can be. Rimfire 50cc or 65cc electric on 12s. My ESM fw-190 d9 flies beautifully on a rimfire 65 turning a 21x14. You could put a 26x12 3 blade on that motor and it'd be happy.

As far as running a 110 on 10s, sure it might do it ok when its not strained, but on a 20# plane that requires higher throttle to maintain flight the a lazy slow cub, you're gonna blow the motor and lose the aircraft.

You don't have to give up on that la-7, just get a different motor. Turnigy has an easymatch g160 245kv for half the price of an eflite 160 at hobbyking.com and you could use your 10s batteries. A nice 18x12 or 20x10 prop would work nicely.

In the electric power classifieds, a guy is selling a 50cc electric outrunner. Might be just the ticket, though i know nothing about that brand.
