BTW more motors doesn't necessarily make more speed....for a high speed setup one high rpm, powerful motor is better...Two motors is better for a heavy rig like a bomber.

Oh...Or do you have two and plan on trying them both to see what one gets you better speed?
Zoom Master

that is true but dont worry im gonna keep the weight as low as I can lets assume the weight of the frame is 200 grams with all the batteries the motor and the electronics (and the covering) my electronics will come to 200-300 grams Sao yeah 400-500 grams for the weight and keep in mind this is all estimated weight........

no no im planning on building just one and im deciding between 2 motors.....

Do you have a link for the motor?
Zoom Master
Elite member
yeah no links but ill either use the emax eco 2 or a speedybee 2807 motor
Houndpup Rc
Legendary member
Yeah i use the Emax Eco II 2306 2400kv...what size you thinkin?
Zoom Master
Elite member
size ? im assuming ur taking about the prop ill use maybe 5 inch prop or maybe a 6 inch ill try to find those props that those hjk speedwings use and use those
Zoom Master
Elite member
yeah maybe ill use a Graupner cam speed prop

No size of motor...I am guessing 2207?
Zoom Master
Elite member
yeah 2207
Zoom Master

and btw does a foamboard speedwing of that size that will go 300 mph need a airfoil ?
Zoom Master
Elite member
speedwings like the Sharknado dont have a airfoil and a lot of wood models as well

Hmmmmmm. I doubt you are going to hit even 150mph with that....Here's a video where I have my 2306 (Which is basically the same size but slightly less powerful.) on a 24.5" wing span and I am hitting about 65-75mph....

yeah I know 300 mph is a HUGE stretch but if I can even hit 150 mph ill be happy ill look at some more motorsHmmmmmm. I doubt you are going to hit even 150mph with that....Here's a video where I have my 2306 (Which is basically the same size but slightly less powerful.) on a 24.5" wing span and I am hitting about 65-75mph....

what about a 2807 motorHmmmmmm. I doubt you are going to hit even 150mph with that....Here's a video where I have my 2306 (Which is basically the same size but slightly less powerful.) on a 24.5" wing span and I am hitting about 65-75mph....

Yeah I bought one of those recently to put on a drone...They are lower rpm but stronger...You want to find something with higher rpm like the Iflght 2207 2750kv....Even that might be less than what you want.

hmm nice alright then ill maybe go for this motor and a 6s lipo and realistically im not reaching 300 mph with such a small plane and such small motors the max ill be be able to reach is 200 mph or maybe a bit above and that im gonna do with a T motor F80 or a iflight 2207
Zoom Master

to reach 300 mph I will need a bigger airframe like the apex phantom
