Could not wait any longer for the Sukhoi Su-26m BNF so, I bought this today WATTAGE SUKHOI SU-31 EP .Its a old model that has been out for about 7years now. (should get it by this coming thursday)https://www.rcgroups.com/forums/show...t=SUKHOI+SU+31
It comes with a geared brushed motor which I will convert over too outrunner brushless. If any body may also want one, I bought the last one at Graves R/C but ,I didn't find another location also selling them still---> http://www.newcreations-rc.com/Produ...mnumber=128418

Parkzone Sukhoi Su-26m BNF
Specifications
Wingspan: 15.75 in (400mm)
Overall Length: 14.25 in (366mm)
Flying Weight: 1.1 oz (34 g)

The WATTAGE SUKHOI SU-31 EP is only 13.75 INCHES bigger in wing span, and only 6.25 inches larger in length. So all in all they are pretty close in size.
The extra weight is much to due with the old technology electronics used at the time of review.
I plan on using Tower Pro SG50 5 Gram Micro Servos,
Futaba R617FS 7-Channel 2.4GHz FASST Receiver(Weight: 0.34oz (9.8g) with case, 0.25oz (7g) without case)
The motor I think might work ,is one that I have laying around .It's a Raiden 400-1300kv brushless.I plan on using Li-Poly Battery - 15C 800mah 7.4V +JST as the battery. I will use at first a 18amp speed controller and test with my watt meter prop amps .
Please let me know if this set up that I am thinking of using will work or if there is a better set up for this plane in brushless please let me know.
Thanks!
