I destroyed my replacement Tinyhawk 2 and wanted to build something with the spare parts. I did not do the proper research before buying the frame and thought I could use the TH2 motors. Not so. I ended up buying new motors. I was able to initially use the vtx from the TH2, but ended up buring out the first AIO, and replacing it with this one that has its own VTX. Another TH2 part goes back in the bin. Things that I did use from my TH2 (basically) free:

Runcam nano 2 camera
motor bolts
1s batteries
power connector
red led strip

I am also using a spare TBS vtx antenna.

I installed a fullspeed nano rx at first, but again not having properly researched, I did not realize it was D8 and my controller does not support this mode (x-liteS) . I switched it out for an xm+ (that was intended for a 2.5 build). It was overkill and was moved to the more appropriate build. It's been replaced with an FRSKY Archer M+ to closer match the range of the 50w vtx max.
Impressions on archer m+ vs xm+:
M+ needs a higher version of ISRM ( 2.1.0)
XM + does not work on ISRM (2.1.0) only on ISRM(1.1.3) from what I gather.
I have to flash the firmware when I use my other quad. Its not hard, just a pain in the ass.

M+ is barely keeping up with my 50w vtx flying around my property. Im getting RSSI around 30-40 when my video starts to flicker.
XM+ is overkill for my 50w vtx flying around my property. Im getting RSSI around 65-80 when my video starts to flicker.

Which would I get next?
For the price (they cost the same) and the features I would go with the XM+ hands down.
Not having to hit the bind button for binding in Access is nice and being able to update firmware on the receiver OTA( cable free ) is also great. But...I would gladly trade that convenience for the extended range I get with the xm+.

The canopy is 4 zip ties and the camera is held in place with heat shrink with a hole cut in it for the lens, and another zip tie. The canopy does not sit straight and needs constant adjustment, thus the name. V2 will have improvements. Amazingly there is no camera vibrations. Stretch first, then cut a small circle in one side... try not to have any sharp angles in your cut or it will tear when you try to slide camera lens through.
The landing gear is also made from 3 short zip ties.

Lastly, I added in the led strip for some attitude.

My first impressions are this thing sounds angry and flys like one of those super fat bumble bees. I am using the stock dump for the alpha 65 and the next step is to dial in some flight goodness. I am getting around 2.45-3 min of flight time.
Further flying rate this as my favorite quad so far, even with the super twitchy stock pids its still super fun. Next will be pid tuning.

Ever worry about burning up an ESC? Nick Burns made a video about how pushers can burn out an ESC easily if your not careful.

I added zip tie landing gear so the props are about a 1/4 inch from the ground and I fly mostly over concrete. I am not any more worried than I would be from a puller :)

Good idea!

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
