Tinyhawk freestyle mod

The tinyhawk freestyle is an awesome micro...super fun but is limited by a crap 25mw vtx & rx....

You cant fly around thick brush or your neighbors wife without rx loss or hitting fail-safe.

So its time to empty my swear jar at coin star & find some parts to send it.

First order of business... Upgrade the vtx and Rx..
Found an awesome sled on the site where I bought some leds that allows you to mount a TBS Nano VTX and XM+ rx.
Let me tell you...if your jacked up on three cans of rockstar and a bag of skittles this is not a soldering task for you... my swear jar is now re filled with enough cash to buy dji products.
You will definitely need some helping hands and a magnifying device to be sure your soldering joints arent bridging on the original vtx pins and that the gaps between the sled & vtx have solid connection/support.
The sled allows you the option to use a crossfire setup but Im a cheap a55... and the XM+ was only $12, Ive gone out to a little over 1.5km previously with this rx which is more than enough range for any micro.

Next was finding a camera that didnt make everything look like I was watching cc tv from 7/11 robbery footage, so a runcam racer nano was added... rather than 3d print out a mount, I found a complete frame from microheli that came with a proper camera mount and changed the overall airframe.
Everything is a straight forward swap... snip the zipties for the motor wires, & vtx antenna... and bam doneski...

I experimented with gem fan 2540 props in pic but I have come to the conclusion they are garbage, the motors seemed to be overworked & struggled with lift due to the flex, less pitch and smaller diameter... I found its best to utilize stock emax Avan props as they provided the best punch out and input response, pair that with some modified PID settings this micro flies suprisingly better the most 5" stock quads...

My range on this quad has more than quadrupled with this setup... no more failsafes.. even with the vtx cranked up to 400mw it had enough penetration behind trees to make your ex girlfriend jealous. I am still getting 7-8 min of aggressive flight times with two 1s 650 gnb lipos.

This is a fun quick corona virus-isolation build that will definitely get the most range out of your tinyhawk.

i used my THFS as a testing rig for several things and it came to a point that i said "wow this thing isnt breaking". I made some custom mountings and tried it with 3" on 2s. IT FELT GREAT. In short, the board is great and i hope to see more mods like thiss!!

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
