Carbon Fiber Easy Star for sale

I am currently working on creating a hollow easy star frame for the ultimate UAV. Since it will be hollow, you can place large amounts of weight right at the CG without having to ballast out the plane. You can also attach a larger motor or have landing gear hardpoints built in. I can customize the design to meet anyones needs (pylon racing, ultra-light, see though, rough landings, etc).

 

All materials used are top quality aerospace grade. Only the highest grade Pro-Set epoxy is used and any carbon or fiberglass used is Aerospace grade, not commercial as you would normally get online.

 

(Price is based on materials used. Baseline model will be around $60)

I lately have thought how cool it would be to have a carbon fiber EZ* and would like to do it but I have never done that kind of work so that could be an expensive failure. Are you doing just the Fuse or the entire plane? I may be interested in one. Do you have any pics of an EZ* or other planes you have done?

I don't have any pictures of the EZ* yet as I am still building the moulds. I am only doing the fuse, but I have included the canopy so less parts are needed and you get more space. I would do the wings too but the curved geometry makes it very difficult to create a mould. I am originally doing this to help out a friend with his senior design project, but since the cost of materials is so high and I figure others might want one, it would be nice re-coup some of the costs.

I have done other aircraft for work, but due to security restrictions I am unable to post pictures.

Awesome. Well maybe once you have some stuff to take pics of you will have to keep us updated. I would be very much interested in a fiber EZ*.

i would be in for one at the $60 or so mark for the fuselage with post hole reinforcement LOL seriously

I would consider getting one too. Curious about details like weight compared to stock.

Well if you fill it up with Hydrogen I'm sure you could get it to be very light. Just watch out for motor sparks!

James can you tell we are fiening for more already? You need to give us a fix, just a lil hold me over...lol

I am also working on a glass EZ Star. Molds are built and I have a fuse being joined as I write. I was under the impression that carbon fiber screws up the electronics. Is everything going to be mounted on the outside?

No. For starters you have to use the correct epoxy and have some knowledge about EMI. Fiberglass has the same problems as carbon just to less of a degree. This is why you normally have to use expensive quartz impregnated glass or other tricks that I will be keeping a secret (unless the price is right). If you are joining the fuse together, how are you gaining access to the space you freed up on the inside by making it glass in the first place?

You can just use a spektrum receiver for carbon fiber, as it has longer antenas and some nifty through hull exit ways for them. But wondering if it helps inside for shielding noisy things, or compounds the internal interference, or worse; inhibits magnetomers etc.

that would be gr8 james, I would be interested too if wings are available too.
Having said that However the original easy star has one special quality that would be hard to duplicate with CF or GF fuselages. It takes abuses of hard landings very well including some good crashings. and hot water+ spoon works wonder to bruised easystar very well I believe :)
Also pls take into size of DIY AP currently available/used here into considerations .Thanks for sharing your efforts.

Things wont be available since the stock wings with a couple small mods will be better than anything I can create. I am sure I could try to build the moulds for the wings, but I'm not really sure how worth it is to make them.

As for hard landings, it is very easy to create a fiber fuse that can withstand a lot of abuse. If you really wanted, I can create one to stop a bullet ;).

I am planning on creating a sandwich core fuse for those that want the ultimate light weight pylon racer, but I have yet to test the foamcore parts I've created.
