Tyrocodile 129 Geprc (crocodile)

So I decided to rip apart my backup tyro 129 and remix it... I wasn't a big fan of the bottom mount battery system as I dont like how it just dangles the battery and carries the sagging goods like a high school prom queen on her 40th birthday.

I was fond of the geprc crocodile frame with all the room on the top plate for large batteries... but wasnt willing to take chances with Banggood after they lost two shipments and my last order was almost a 4 month ship time...

So I found a Geprc crocodile 7" frame at racedayquads (the best guys in the business for parts eff you banggood ) and a runcam split micro for a good deal and decided to rip apart the tyro 129 and put all its components into new frame. And to give it better range... picked up a AKK race ranger 1000mw vtx from amazon $20. Turns out it the Race Ranger is a direct plug and play for the Tyro 129 with no need to repin or solder!

Everything went well until adding the top plate...the fc stack with vtx is much too tall by about 3mm, so I ended up mounting the vtx up front hovering over the runcam split board and am running a 8" mccx to sma connector all the way to back tpu mount so I could still have room to strap a gopro to the front if I wanted to with no forward antennas in the way.

This thing is massive.... and it flys ok with the stock tyro129 tune but I'll definitely be playing with the pids to dial it, in smooth out the small jitters and throttle jello. I strapped a 5000mah 100c battery and got a little more than 16 minutes cruising but trying to snap roll or pull of any acro is waay sketchy... give your self some altitude. It pulls off mild freestyle better with a 3000mah battery which is still heavy AF but gives you around 10-11minutes of flight time.

What did you settle into for a battery for this one?

I like to use the HNB 4S 3000mah 60c for good flight time with the ability to do mild acro & powerloops while carrying a gopro and you still get 10-11mins of flight.

With the 5000mah 4s battery, It is only good for cinematic long range cruising as it is quite heavy with the battery & gopro, the weight makes slow to recover out of steep dives so give your self some altitude if you attempt acro, 15 - 18 minutes actually gets tiring. The farthest I flown so far with this set up as my area crowded is 5.5 miles round trip or 2.75 miles/4400km one way with plenty of battery left.

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..
