New bimRC Ducted Fan Line

Hey everyone,
Since I remade my entire line, I decided to start a new thread. My other thread didn't really go anywhere. It was also disorganized and was not updated like I hoped I would. This one will have all collected information on my units.

Post 1: available units with dimensional specs
Post 2: available performance specs
Post 3: purchasing

couldn't get the esc to spin it over 97,000

Data collected with a custom motor, thus no current readings.
If you know how fast your motor is spinning the fan this chart will give a rough idea of the static thrust.

- All units are made to order. I can not stock them since I am not a big time retailer. I wish I could, but I can't. Because of this, there is a lead time of 8 to 12 days.

- All units marked with an asterisk (*) are made of a different, higher precision material which has an initial handling charge of $5 (there is no way around this). What I can do is compile up to 20 units (or parts) of this material in one file so that the $5 handling charge is only applied once.

- Every other unit is subjected to a $1.50 handling charge. The same applies as above.

- Shipping is a flat $6.50.

- Group Orders: If you would like, a group order can be placed. The group order will split the fees among the amount of individuals ordering. If no one else chooses to jump in, I will. During group orders, the order will come to me. I then clean, trim, throw in some mounting screws (if applicable), and reship at no additional cost.

Prices:

All 22mm and smaller rotors* are $1 each.

I can get the 30mm weight for you tomorrow. I can calculate a theoretical weight for the others, but can not provide an actual weight.

Edit:
I looked up one of my older threads. I found a weight of 2.78g for the shroud.

I got rid of the "n" and "m". It just confuses things a little. They should just be classified by size. They are the same though, just renamed.

Or are you asking about weights? If so, then I will retrieve that info a little later. I am busy with school work at them moment.

Sorry I took so long. The theoretical weight of the 35mm is 3.22g. The actual weight of the 30mm is 2.78g.

I'd love to give the fans a go, BIM, but I'm guessing shipping to the UK would be pretty costly. UK shipping would be $9.50. Also, if you're after feedback this century, I'm probably not the best test pilot. My build speed is extremely slow - it doesn't help that I flit back and forth between projects.

I had a look at the list of fans you do and have a few questions - do you want me to post them in your thread for consistency's sake?

- what motor size would your EDF30s take?
Any motor whose diameter is 12mm.
- are the shrouds designed for push fit motors?
They all have deep hubs so positioning is no issue. There are screw holes as well to prevent the motor from twisting from torque.
- do the prices include fan and shroud?
These are just the shrouds.
- why do some have intake lip options and others not?
They were all made with different applications in mind. If needed, I can add lips or remove lips on any of them. Just ask.
- would you put your products on Ebay?
I've never considered it before. I'm not a big fan of ebay though. I will definitely look into it though.

Once again, thanks for your responses!
Don't we all flirt with many different projects at once.

Are there rotors available for the df 15 and 18? I could not find them in your awesome shapeways page. Also do you have any stats for the df15? I'm planning on building a vampire or something else with good wing area as an indoor micro floater with undercamber. I've ordered a 3ch Dt rx52 and nanoact actuators and I'm looking for a micro fan. I need one that won't make it a rocket, I was planning on making a fan out of foam but i wanted something more sturdy and saw your beautiful fans. I want to try both the 15 and the 18mm fans if they are available. Thanks

There rotors are available for the 18 and 20, but it would cost a small fortune (due to the $5 handling fee) if you got them individually. If you let me know how much you want, then I can make it so that the fee would only need to be paid once...

I'll have to get back to you. trying to finish up some school work

The DF15 is still untested. The original set was made for a particular motor which took a lot of work to makke, so that didn't happen. The 15 has no eligible motor options so far. The only motor I can think of is a 4x11 8.5ohm.

The DF18 is the next option. We are still working on ways to increase performance.

After my 12" Isis, I want to either make a 737 or F22. Both have the wing area and would use dual fans. My single option would be an F35 since it has those massive control surfaces. I'ld use two microacts for the fighters. Two hinge acts for aileron and one microact for elevator on the 737. Of course they would all be 18mm models. Too bad no one found a money tree seed though.

I've got another question and that is: will nanoacts be strong enough to use both in the elevator and ailerons on a vampire or an arado ar-234? I also thought of hingeacts but they are too big actually, I'm planning on squeezing the biggest fan possible into the Vamp without covering the whole wing with the intakes. Actually, I'm trying to make it as small as possible with the fans available right now lol , I mostly like post WW2 warbirds and they all have very small jet engines and intakes compared to modern jets, the f14 tomcat has 150% FSA intakes

Also the price of the cases and rotors for the df18 are not really important for me, as i have to pay a fortune to ship them here, to Turkey anyway
