UPDATED* Botgrinder Grinderino 5 inch Freestyle Frame


Introducing the Fiverino.

 

During a regular customer service email, one of our customers (Keith Stanley) asked us if we have ever considered making 5 inch Grinderino arms. We always thought of the Botgrinder frame line as 3.5" - 4" = Grinderino and 5" = Demibot. It hadn't occured to us to make 5" arms for the Grinderino body and build it with 2Fiddy sized 2004 motors. So... we tried it... we LOVED it, then we sent it to Botgrinder to try out. Aaaand of course, he loves it too, so here we are.

For those of you who have experienced the insta-flow goodness of a 2Fiddy... you already know. (#ifyouknowyouknow) When you convert your Grinderino to 5", it will give you all the feelz of pure freestyle flight enjoyment, mind blowing control, and a QUIET but ridiculously powerful setup.

 

I recommend the T-Motor 2203.5 2850 for 6S or the 1804 3400 4S

 

If you love your Demibot, but wish you had one that's juuuust a little lighter, your wishes have been granted!

When Botgrinder asked if we can make him a 3.5" frame, he said he wants something just as good as the Demibot but in a smaller package. It took a bit of adjustment, but I think we hit the mark. As for flight controllers, this frame will fit a single board whoop style AIO, or a 20 x 20 stack. The rear of the frame provides plenty of space to fit a VTX of your choice, and just the same, the front will accommodate any camera. 

And if you were curious... Yes, this is less than 250g all up weight!

UPDATE: The Grinderino arms are now compatible with 9x9mm motor mounting!
