FYI you do not need to cut the stryfe to fit the motors in so NO "Motor cover" is required.. Mine has motor covers because previously i was running 180's. This means your blaster can look completely stock if you wish.

Printed on Tronxy X3A 3D Printer

The Licnence you agree to when downloading this thing prevents you from making a profit from MY thing. This means you CAN NOT sell this or any of my other things on places like Ebay, Facebook, Forums or Etsy. You also may Not sell My parts as Part of a complete blaster. I don't profit from putting this thing us as a Free download and therefore no one else should too.

Due to the specific print requirements required to print a successful Ultra cage and Wheels we have now opened a Etsy store. Purchasing from this store you can be assured a HIGH quality product .. Not some cheap disappointing rubbish.
Also a complete drop in kits including the cage and wheels are also available to those who are looking for a simple drop in kit.

ESC Selection
To start with it's useful to know that there are 3 Basic kinds of Blhehi ESC's
they are

Blheli (Oldest)
Blheil_s (Old)
Blheil_32 (Current)

Though we have previously recommend the Emax lightnings which are "Blheli" these are no longer recommend for a few reasons and now we are recommending " Hobbywing XRotor Micro 30A BLheli_32 DShot1200"

We are recommending Blheli_32 in general because they have significantly less trigger delay than the older BLheli ESC AND they have MUCH faster spinup to a limited RPM ..

We are recommending "Hobbywing XRotor Micro 30A BLheli_32 DShot1200" Specifically because these have been tested to have effectively NO trigger delay at all and therefore are ideal for our use case. Please be aware that there are other "Hobbywing XRotor Micro BLheli_32" Esc's but these have not been tested to have 0 trigger lag. Only the recommended ESC has been proven to have basically no lag.

Can you use what ever esc you want ?
Yes you can and you could say that if you have a stryfe with a manual pusher then you'll be hard pressed to tell a delay of 0.1 of a second and it doesn't matter anyway cos you have to pre pull the rev trigger anyway. HOWEVER if you have a Auto pusher and want the fastest response possible then the recommended ones are currently your best and only option (and only independently verified). IF you do wish to go with some other ESC please ensure it's Blheli_32 not any of the older models

Hobbywing XRotor Micro 30A BLheli_32 DShot1200. Two ESC's are required.
