I just received my X4 batch 6. I am a little dismayed that there were absolutely no assembly instructions, reference materials, or even a single page of info identifying assembly instruction resources.
Can anyone please direct me to the most thorough written and/or video assembly guides available.
The X4 is definitely a DIY machine. There is a guide of sorts in these forums.

Nothing in this document should be taken as fact (we all make mistakes). This is meant to pool the community’s knowledge in one place, so that Paul can use it as a starting off point for the official manual, which will be published on
Note from a Batch 6 customer:
It maybe worthwhile…
Several people, including myself, have documented our builds here as well. The X4 is more of a community of enthusiasts kit than a commercial product.
Welcome to our little piece of the world of aviation.
I am also starting on my X4 batch 6. These forum links have been the most help so far:
[OpenPPG 22 v3.1 Build Video] (
OpenPPG 22 v3.1 Build Video (part 1) - YouTube)
[Greg’s Batch 4 build] ( Greg's Batch 4 build, maintenance, repairs, upgrades)
And especially the link to another builder’s photos in the latter. There seem to have been running design changes to the kits and material mismatch / shortages (mainly fasteners) have happened.
I’m just starting on the wiring.
Thank you, all for the great info! I’m looking forward to getting the X4 assembled. My 4 bonkos arrived today… the 7S type. Now, I’m wondering as to what is the best charger to get for them.
