Jakub Frame Thread

As there is some usefull stuff around for the Jakub Quad frame, and now for the Hexacopter and soon Tricopter as well, I just thought that they warrented a thread of their own to make life simpler, and to help others if the info is in the same place.

To date I have only build the Fibre Quad frame, for which there is a construction video over on the KKMulticopter site.

Here are the images of my Quad as it went through build, and hopefully I will be able to add my Hex and Tri copters soon.

The Quad is powered by RCTimer A2830/11 1000kv motors with 8x4.5 props, and all driven form a SMD KK controller

Jakub Tricopter

Ok, post finally arrived today and dropped a small package off from Jakub.

I have now got a few evening work to build the Tricopter and Hexacopter frames.

The Tri will be the first to get some attention and will be running on RCTimer 750 KV motors (as will the Hex), Hobbywing 30A ESC's and of course the KK SMD controller.

Just unboxed so far and looks to be all there, and parts nice and cleanly machined.

As I have build a few Tricopters I may make a few mods as this one goes together based on what I have learnt to date. Don't get me wrong, as there appears to be nothing wrong with what you get, but simple things like rubber under the motors and stuff like that does in my experience make a difference on the final product.

Mike.

I think you may need to hurry on that one as I have nearly worked it all out doing a dry assembly already

Ok, first thing I recon'd was to get the brass nuts fitted to the copper clad board which locate the screws for the front arms.

I used some gash 3 mm screws (not made of brass) to locate the nuts in position, used a good heat on the Iron and all went well. Don't over tighten the scres as whe nit all gets hot the metal parts will expand and risk damaging the glass board, just hand tight to hold the screws in place, oh don't forget to let it cool down before you handle it .

More to follow, Mike.

Just done a "dry" assembly to see how it all fits together and looks nice!

Still got to put it together properly but now I have a good idea where all the bits go I can work through this now.

Still ned to put the motors on so that is the next test build to do, then it's put it together or real. To date I have always used an enclosed box to put the controller in to keep dust out and still have not decided if I will keep the open frame design or box it up in the normal storage tub. Guess I'll see what the options look like.

Ok, progressing along, mod number 1.

Nothing earth shattering but just something I wanted to do. The design of the yaw mount allows the tail to rotate in the mount, and is secured by a nut and spring washer.

Due to the location, not being the easiest to access once the motor is fitted, I have elected to replace the nut and washer with a nylock. That way a quick visual inspection that the thread is still visable in the position is all that is required, instead of having to check the nut with a spanner. Just a time saver really but easy to do as part of the build.

Mike.

IMO better in this place will be spring washer - it is safer than nylock.

I'm working with video assembly guide, but will finish it tomorrow,
wait a few hour, please

I'm quite surprised at how well the fiberglass quad frame copes with some quite big falls. Today I lost control several times at varying heights between 10 and 20 feet and just chopped power and my quad tumbled to the ground. Only slight damage I've found is a chip on the end of one arm where the motor mounts to the frame. This was landing onto a road, not a nice soft grass field.

I need some new blades though, because I've well and truly abused my current set and the vibration gets too much after 3/4 throttle. I just ordered a load more and also some prop savers that should actually fit my motors, unlike my first ones, which don't.

Hi guys

Most important than web-site are frame designs.
I'm working hard with new frames - in a few days will be ready
new quad frame with place for GoPro (60-cm class .

In pipeline is 36cm quad frame weight less than 100g,
and a few other designs from really cheap (probably <40e)
to very nice looking etc.

I really don't like shops with "out of stock" in offer
Web shop will start soon but first I'll finish a few new frames...
