6" GEPRC GEP-TX Chimp - The Rocketship

By The Lightning Stalker on Nov 01, 2016

2  603  19

The Chimp frame has a nice 4mm thick CF baseplate/arms, good motor protection, and adjustable GoPro mount that is good for carrying small payloads. The Flip 32 Omnibus came highly recommended.

If you decide to build this, use Tiger F80 motors if you can afford them. Either the 1900 or 2200KV and run 4 or 5S high ampacity battery cells.

What sort of range do you get with the SP831/833 vtx?

The Lightning Stalker   Apr 06, 2018 

It's about the same as some of my other 200mW VTX when set to 600mW. I'm not sure why. It can get a bit noisy behind a tree at 100m.

How's the build coming together? My Chimp should be arriving in the next couple days.

Did you remove the casing from the receiver? I'm sure if you removed the pins from your FC, got a smaller receiver and trimmed a lot of the excess wire you could fit it all. Have a look at mine. I managed to fit it all in there with a nice pocket of space above the FC. I love the design of this frame and I'm looking forward to many flights.

The Lightning Stalker   Dec 27, 2016 

Yes I decased the rx, but it is thickish and still no space for the VTX
Eventually I will probably end up switching to the XSR and some high quality thin heatsrhink. At that point I might just upgrade to the F4 without the pins and use the F3 in a Flamewheel clone.

Whiffles   Dec 27, 2016 

No real need to switch to F4 at this point. I'd probably just de-pin the one you've got. You could even cut the pins and solder to the tips. But if it's too much trouble you could get the original Omnibus F3 for about $23. It mainly lacks the current sensor over the pro, so you wouldn't be missing too much.

Did you add those pins to the FC? Why not solder the wires directly to the board? My GEP-TX5 is well under way. I should be finished this week. Can't wait to see how it flies.

Yeah, most folks are soldering directly to the boards now, but if you've got it working like this you might as well keep at it until you need to make repairs. Then you can start to trim it down. How's it fly?

The Lightning Stalker   Dec 19, 2016 

I haven't been able to fly it yet. Hopefully sometime soon

I just maidened it today. The thing is a rocket ship. I could not be more pleased.

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..
