I have to be honest I have had my eye on this kit for a while. It certainly does look nice and you have done a fantastic job with the detail. Its in the next kit to buy list after iv bought the mini jazz kit and started and finished the 1/4 scale cub scratch build. I think if I drop on some spare cash I will definitely plunge in and get the kit and put it on the shelf and that way I can keep getting the parts here and there till I have everything for it. Glad the maiden went well

If its an open structure covered with fabric it shouldn't cause any interference. If it was sheeted metal it definatly would cause issues. From what people have said that goes down the route I am they dont have issues only where sheet metal is used rubber pads are a must ti reduce vibration I agree. The only down side ti carbon rod and tube is like you say the bends will be under load all the time :/. I will do range checks and use 2 4ghz I think 35mhz would suffer interference.

Well just had a quick chat with my friend paul at one off welding and engineering and he will be happy to build and weld the fuse and tail for me on condition I do the cuting and bending and shapingvof parts required and he is doing the welding and il watch learn and have a go on scrap material. Cost hasn't been discussed but his level of quality in is work is outstanding so the projects a go ahead with the stainless steel. Im starting to feel slightly excited now haha. I will document the build on here but it will have to after my chemotherapy is completed and once I have bought all materials for the fuselage. Il be able to spend my revovery doing somthing il enjoy whilst I await my op date to come through. So it will be a long build log but I promiss to make it a good one to read there just maybee breaks between parts of the build but im sure paul can email me pictures and il continue to update the thread whilst in hosi.

Flight1 thats where I got my info from and ideas. What puzzles me is he does a 1/3 scale cub with scale wing bolting system etc and scale built wing but did not do it on the older 1/4th scale model. You have to be honnest the finished models look fantastic but il be damned if im paying over ?2000 for the kit alone thats not including postage or import duty and tax and so forth. There is also so much room to add more detail to the cub. I betbthe finished airframe is rock solid though

looking at the structure I could build the front with stainless steel but where it gets complicated wing backwards I could use some wood for the rest and turn the ends down of the upper and lower longerons and epoxy them into the stainless tubing to join the rear wooden section to the front metal section which would still allow me to keep the main strength in the center of the plane for the wing mounting to be built scale and also be strong and versatile. allot of scale cubs lack strength in the center where the wing mounts due to the scale opening door. this is another reason why I haven't gone out and bought a kit. The problem I have with CF is it may not work and the vibrations may weaken the joints in the airframe of the fus. its allot of money on CF if it turns out to be a failure, The stainless steel tubing is a working tried and tested method so it is doable just very tricky. the 3rd method iv just mentioned seems the be a better approach but then if I get in touch with my friend who is an engineer by trade and he says its possible to teach me or even build the framework from my design for the right cost I will go down that route. keep your opinions coming guys.

Thanks for that martin I will have a look shortly. Obviously I will need to learn to silver solder but im in the process of trying to get my friend paul who can do this to teach me when I finally return home. I can solder circuit boards brilliantly because I work in a computer shop and specialize in soldering motherboards etc for them, I can solder piano wire but would love to learn how to silver solder to take my hobby to the next level and be able to push the wood aside for once and use a metal tubing to replicate the full size. call it extreme which some of you may think so but when your building a scale model you try to replicate things the full size would have had or be made from right? so its only taking the realism to the next level and in the process showing your skills and ability's. I would also love to learn to make my own exhausts so learning how to silver solder is a must .

brass is more expensive then the carbon tube and harder to find in 1 meter+ lengths, though may be perfect for building a scale under carriage which I intend to replicate the cubs full size one. I don't see point in paying 100 quid plus to robart for there 1/4 version when I could build it my self for half the cost. yes ok it means more work but that's what the hobby is all about. pushing our own skills to the limit and learning new things and id rather use the 50 quid I saved and put it towards some coverall or some solar tex. or some other item I can not make . This is not an impossible build it just has to be planned very carefully so when it comes to designing I have all my answers and I know the important sizes and weights and factors about what material to use where, it will also help make sure the project keeps going and does not come to a stand still due to a problem halfway though rendering the whole project as a waist of time. I also want the model to be safe when built because the last thing I want is it suffering a mechanical failure due to a design fault of my own and it crashing and hurting someone. Iv not worked with brass but I do no it can be solderd. is it classed as a soft metal or a hard metal. if its a hard metal then il consider using it for the under carriage.

Also the way the wing mounts on has been changed which if anyone reading this that knows there j3's well enough they will also spot this. I want to build a scale wing and use the same mounting method. there's a 1/3rd scale plan set for a cub drawn by bob nelitz and he uses the full size method of attaching the wing and it works great. although he had to build a metal tube frame work for the strength side of things in the center of the fus and attach the rest of the wooden structure to it. The cub above is stainless steel and then powder coated you have to admit it looks bloody great and was reported to be light and stronger then a built up wooden structure.

I think the braizing with ss is abit too complex to be fair. don't get me wrong I would love to go that route if it can be done. I will have to get hold of my friend who is an engineer by trade and makes one off café racer parts for motor bikes and see what he thinks. downside to that is it will have to wait due to me being in hospital but in all honesty im more familiar with the carbon method. I also agree in regards to weight for weight and was going to go with the same outside diameter but go along with a much smaller inside diameter. Here's a picture of what I want to achieve though on this models frame there is several members missing and several tubes in the wrong place etc. but this proves it is not impossible. tho model is 1/4 scale which is what I am also wanting to work to in size and scale.

Ok so I have some ideas for this winters build and there's a few things I am still trying to work out before I can put pencil to paper and start and do a little designing Before  making a final plan to build from. I know you can silver solder the stainless steel tubing and it will be strong if done correctly, However creating a good solid T piece with Carbon Can be difficult right?. Cutting it short I am thinking of framing up a fuselage and want to go the extra mile instead of using balsa and so forth. The full size aircraft uses tubing so wanting to replicate the full sizes structure the same way to add to the detail of the model. might sound like a lot of messing around but I just want to go that extra mile.   Any input would be great because I can not silver solder stainless steel and my only other option would be carbon fiber which is good because I used to be a fiberglasser. I am just a little concerned of the strength compared to stainless and also strength of making 45 and 90 degree joints. I do have some ideas as to how to make a form of insert that helps anchor the 2 tubes together internally for the carbon fiber method but a little worried as to the overall strength of the tube itself over the stainless steel tube. As said before any info will be great Edited By Brent on 07/09/2014 16:14:12

Cheers forv that. As soon as net comes back on il go on laptop and check the links out. Keep looking at thev hitec aurora 9 it seems like it will be a good all round tranny to go with. Last trannyvi had was a sanwa / airtronics rd6000 then I got american airtronics version with 2.4ghz. What others is there thats a good tranny. I was warned ti stay away from spectrums because there troublesome.

I think it is very close specs to the motor but im sure mine is just under 4500kv. im not used to this new ratings on electrics im used to the old ways such as speed 400 540 and 600 etc. so im learning on that side of things because iv always loved engines but now im at the point where I hate having to tune engines etc. so the smaller stuff will be electric and the large scale will be petrol engines as they are more reliable and efficient then glow. il try get hold of my house mate and see if he will go in my room and check the box the motor came in and same for speed controller because if they can be used it will save me allot and I can use that money I save for a good second hand 2.4ghz radio. I figure a second hand 2.4ghz transmitter is fine and il just buy new receiver's rather then trust 2nd hand ones. I just cant wait to get out of hosi so I can start and build a building bench. a trip to wicks or b&q will be in order for a nice flat skinned door as a surface. just need to find out where I can get some thin cork to cover the top of it in so pins will go in well for building. a door will be a perfect size for any model I wish to build because anything bigger then a door will be too big a project, excluding wings . From what iv seen of these new electric setups im very impressed because years ago the motors were no where near as powerful and usually the battery's weighed more then an engine and fully fueled tank Can you over size props on this type of motor to stop it from being too powerful or would it be too much strain on the lipos esc and motor itself. im dumb with this new electrics job. may have to go read about it on the elec forums and see If I can find any beginner's guides to make things clearer to me lol.

Posted by Birgir on 06/09/2014 13:35:46: Hi Brent and welcome to the Mini-jazzers I finished building mine in the end of July and have flown it several times. I use OS 0.15 and it has quite enough power for everything I´m capable of doing. I made a build log at **LINK** It is in Icelandic but you can choose a translation on that page that uses google translate. Not perfect but helpful if you don’t speak Icelandic. I followed the plans pretty much. I used mini servos with plastic gear but would recommend using metal gear, at least for rudder. I’ve already broken one but abandoned take off so no harm. If you are taking off from a grass field, using a little bit bigger wheels might be wise, and if you are using a tail wheel you should take that into account when building the undercarriage so the take off angle is the same. Welcome again and best wishes for your road back to good health. B. Edited By Birgir on 06/09/2014 14:03:50 Thanks Birgir yes our field is all grass unfortunately, I decided to try helicopters back in January but never finished the one ibought off. I ended up buying the Beam E4 heli and it is only short of a gyro and receiver and transmitter. all the servos in that are mini's and all are metal gear so will use the servos from that with a cheap plastic 9g one for the throttle if I don't chose electric. I bought an align speed controller and motor and 3c 11v lipo along with balance charger its 450 size and was wondering would the motor be suitable for this model. I cant quite remember the details of the esc and motor because there not with me due to being in hospital for the last 3 months. but if the power plant from the heli can be used in this model it will certainly be a better start for me. thanks guys for making me feel welcome and I will check out your link Birgir to your build

thanks Jamie, As for the health its one of those things. As for the mini jazz it will be an easy but quick build to quickly brush up on my skills as well as flying skills. not flown for 4 years but will not have a problem there because i have been flying since i was 11 and im now 28. I am looking for a 1/4 scale project to learn scale building techniques because there's allot of aircraft out there I like and would love to build replicas of and i love attention to detail by going as far as replicating the aircrafts structure to take the build to a higher level where some modeler's don't. Going to keep it simple to start with, 1/4 scale cub should be a good bassis to start from for the ease of building and to learn how to fly them scale also. But from what i saw of the mini jazz's down my local field years ago they were heaps of fun and great flyers too.

Posted by Jamie sawyer on 05/09/2014 21:51:36: Posted by George Pickering on 05/09/2014 15:13:23: can you still buy these kits? if so where sells them and how much are they. Welcome to the forum George, you get them here and also you can pay for a CNC wood pack etc. Just search for the Mini Jazz **s chose my first name for the forumLINK** Thanks Jamie, for some reason it has chosen my first name I go by my middle name (Brent), iv saved the details of the website because it is one model iv always like due to the size, its small and easily put in the boot of the car and probably would make a great model to convert to electric making it even better that a flight box is not needed also. trying to find out some projects for this winter because im out of work due to health issues (chemo and awaiting large op) and I don't want to be just sat at home awaiting it all so decided to return to the hobby for a 4th time lol. Now I have all this free time on my hands im also planning on having a dable with a 1/4 scale cub because I do like scale models for the nice warm lazy spring and summer afternoons and evenings. Will see about ordering it next week so at least when I finaly get out of hospital I have something to build while I recover from my first session of chemo. thanks for the help Jamie

can you still buy these kits? if so where sells them and how much are they.

Id love to drop on a little bi-fly kit they were great fun back in the day when I was a young lad. always dreamed of getting one but could never save money long enough due to my spending money always going on fuel and props haha and then girlfriends came along which was even more expensive. Its a kit that should be updated and brought back out I think.
