Question
Motor for new plane

I am going to order a 20CC Extra 330 Profile 65" Redwing Plane and was wondering if the motor I have will work? I have a HK3226-1400kv, or if anyone has a better suggestion on a motor I would love to know.

I didn't like my aeroworks proX 260 profile as electric, it was kind of hard to fit a big enough battery for the power required and a worth it flight time. They don't mount to the side as well as a smaller more energy dense fuel tank. I used a 4000-5800mah 6s lipo with a 100A ESC and 4258 (can dimensions) 500kv motor not designed for 3D. It could slowly go vertical and barely pull out of a hover when the battery was getting low. I was going to upgrade to a Neu 1917 1y 590kv 8mm shaft which was $350 and longer than advertised, but I figured it would be too nose heavy and too heavy after balancing. I also thought about putting an ASP 1.08 on it, but don't like glow much.

That motor has high kv for a 20cc, you could run a 14" prop on 4s like it is a glow plane, but it would probably fly much better with 16-18" prop using a motor rated around 1800-2200W like the neu 1917, and something with lower kv and more torque. That hk3226 has only 10 poles, a 14-16 pole outrunner would be better. I would use a Scorpion SII-4025-520 with 6s 5Ah and 16x6 to 17x8, I like the look of the turnigy wood electric props over APC.

On my mojo 60 moass and omp fusion I use scorpion 4025-10 and 4025-12 they are old but still powerful today you can find newer version with better bearings. Also. There are alternative take a look also to QQ Potenza brushless which has bigger shaft and bearings for extreme 3D. Or if in bugget hobbyking SK3 series comparable to hacker A50-16 or scorpion 4025.

For ESC I will go for hobbywing 100A v3 or CC for lipos 6s between 4000 and 5000 mah prop 17x8 or 16x8 16x10

Even though it was not designed for electric I converted my prop to electric. Eflight 60 and I think it was 2 3s packs on either side. 3000mah I believe. 7 min flight time if I remember correctly. Stupid power. That plane was sold for my EF 60" edge.

Gas requires very little field equipment and is super easy. If you can run a weed whacker then your 90% there. Tuning can be a challenge for the novice but there are great resources here to help. Most engines these days fly within 1/4 turn of their factory settings in my experience. Give it a try, we are seeing a lot of guys switching back to piston power lately at the field.

the distance part is a bummer but there are canister options or beer can muffler options to tone it down. A canister on a 20 can be very quiet.
