Bayboos on flitetest had powered the flitetest storch with a blue wonder. An 24 gram motor with 80 watts of power. If you could keep the weight low; this would suffice. BTW; this combo is for multirotors. Regards Title: Re: Will this motor work? Help needed Post by: K K Iyer on August 13, 2016, 08:44:48 PM @prasad dsa,
Hi, Flitetest is using this motor of 220watts http://www.altitudehobbies.com/suppo-motors/suppo-2217-7-1250kv-brushless-motor-park-425-equiv What you are considering is 10A, or say 120watts. Probably not enough. In coro it may be heavier too... Someone else (faiz.kadri on this forum) has just completed an FT Storch (in coro) with a DT750. Please check with him too. Regards. (Meanwhile, prabal has given you another perspective...) Title: Re: Will this motor work? Help needed Post by: Prasad Dsa on August 14, 2016, 06:36:33 PM MOtor specs

Help needed Post by: Balakrishna Reddy on August 14, 2016, 07:18:38 PM 2212(stator) motor is same as 2826(rotor) motor. The motor used by flitetest people is 2217(stator) which is 2833(rotor) size.
Your motor is under powered for that model aircraft. If you can modify their design according to your motor by reducing the model weight and size then its good to go. Title: Re: Will this motor work? Help needed Post by: Prasad Dsa on August 15, 2016, 09:06:22 PM Thanks for the suggestion. but i have a doubt, The weight of the plane is 820 grams. The motor has a maximum thrust of 1260 grams. How is gonna be underpowered? My question may seem silly but just clarifying
Title: Re: Will this motor work? Help needed Post by: Balakrishna Reddy on August 15, 2016, 09:40:11 PM Your doubt is good. But you have wrong information.
2212 motor doesn't have that high thrust. My 2826 -1400kv which is same as 2212 -1400kv and when tested ita thrust was 700gms with 3S setup and 8045 slowfly propeller. The motor thrust can be little bit lower than model weight and it works fine. I cannot explain it here but works. However The motor shown in your link from eBay is not really good they are some cheap chinese ones according to what seen on product page. Title: Re: Will this motor work?
