Yes it's OK, I have 2 planes running on that size esc with 8x5 props on that motor and have had no problems, I have had the threaded part of the shaft break on both motors but I use a normal 3mm prop adapter on the non threaded part of the shaft, it's a brilliant little power house! I always keep these motors as spares as well, great motor
These are the servo's I have, HKSCM9-6 Singlechip Digital Micro Servo (6V) 10g / 1.6kg / 0.07s, PRODUCT ID: HKSCM9-6, they are the best of all the standard servo's, If you go to the "FILE" area of teksumo international warehouse you will see my layout there, there are quite a few pic's and of other peoples setups too, if you look at the pic "My layout perfect CoG" you will see my exact layout, the old digital servo's were orange coloured same servo as now just different colour, hope this helps you
If it's bent or broken at the threaded part, that's the usual spot with this motor, cut it off and fit a 3mm collet, both of my motors of this have collets on them now, as for the shaft nearly any 3mm shaft will fit it as long as it has the slot for the circlip.......I have this motor on a teksumo and a 900mm pop wing with a 8x5 master airscrew prop pulling 28 amps at 280watts, the teksumo has been running at that level (countless number of flights) for over 12months, these are brilliant little motors!!
As you are probably aware the teksumo and popwing are nearly the same plane, If you go to teksumo in international warehouse and look in the file area, you will see my setup, I have a Turnigy 2200mah 3s 20c laying lengthways along the centre line where it's protected more from the small EPP buffer , I use a reusable cable tie and velcro to hold the battery in, it balances the wing perfectly with no weights, and I get 10-15 minutes depending on how aggressive I fly, if I had to pick between the popwing and teksumo the teksumo wins for having a stiffer type of epp but both are great fun!!
listing any additional specs you happen to know, like the brand, wingspan flying weight, prop diameter and pitch, KV of stock motor, etc. of your cessna would help..
general rule of thumb you'll want about 150 watts for each kilogram (or 2.2 pounds) of flying weight

1 thumbs up!
I replaced an Art-tech C2830-21 with this motor in a HK/RICCS TB-20 with a 9x6 SF prop and WOW! Full throttle with a Turnigy 1300mah 30-40C battery gave 3.5 minutes vs 5 for the C2830-21; however, the thrust difference was phenomenal. Normal flights with throttle control provides the same 6 minutes as the original setup. Time will tell as to endurance, but for now, I'm having fun.

Nice Motor, no vibrations. Make sure you cyno or epoxy the base to the motor bearing tube as this is mostly where they come apart and the vibrations start instead of over tightening the grub screws as they damage the bearings. I run 8x3.8 TGY props on these and almost always they need a lot of balancing to get a smooth setup. So check this before you blame the motor. Bearings on mine are all good out the box.
Ã³timo motor. Uso ele em uma zagi 90cm com helice 7x6, fica muito rapida

I bought two of these and they are the worst motors I have used , lots of vibrations, run hot, both burnt wiring, got about 30 min out of them, 1300mah 11.1 turnigy bat, 30amp plush turnigy esc, 9x5 prop super hot, 8x6 hot, 8x4 hot , 8x6 3 blade hot, 7x4 not too bad, cost to send back not worth it, and shafts are super soft, not a good buy, I have bought other motors from hk that are great but not these
