Here are some spy shots of my DF-22 project for twin 90mm fans. It should be ready to fly within a month or so. The ready to fly weight came out to 9 pounds and at around 1800 watts it should be a good performer. The length is 65 inches. I am currently making the inlet plugs. Let me know what you think.

More shots.

More!

Even More!

that is really cool.
but i think that it deserves more than 1800watts.

i have a bob e Kat that has the wemo midi with the Hacker B50 13XL on 9s2p tannic 2500's
draws 1450 watts and i get about 5.8 - 6 pounds of thrust.

i highly recommend you up the power im-put.

two hacker B50 12XL on a 8s4p pack would be a wicked set up.
some serious power for some serious fun.

my E-Kat is just as fast as the turbine jets around the sky.

but its your plane and your money.

I have a 6S 4200mah thunder power pack powering each motor and have not decided a motor yet. Does anyone have any info on what Hacker or Mega motor will draw about 40-45 amps? Motocalc says that the Hacker B50 13L will draw just over 40amps, I would like to confrirm that with someone else.

No, a 13L is too hot!!! 13L is a good motor for 15-16 cells, 5S Lipo in the Midi. The 16L should be right at 40 amps, the 15L appr. 45.

This looks fantastic, were you thinking of kitting these?

Have you radared it? What does it do?

My fan Calc for a Thunder Power TP 2100 cell at 6S2P (equal to your 4200 maH cells) would give a power output of 795 Watts at 46 amps. The 16L would be at 42 amps with 782 Watts.

Oh! MY!

That is NICE work Dan....!

Thanks for the replies, it takes me awhile to check back because my laptop is trashed from a virus so I go to the library. As for clocking the speed on radar, that won't work because it is stealth. Looks like the 16 turn hacker seems to be the way to go. That setup would be over 200 watts/lb so the performance should be there. As of now the tailerons are set up and the wings and verticle tail are on, the intake plugs are about half done. My house sold and closes on April 15 so the jet must be complete by then. One last problem is the gear doors. I am trying to decide between closing them with springs or using micro servos.

Servos or tiny pnuematic cylinders.

Go to online catalog, cylinders. For really small cylinders open the .pdf file for the "Clippard Minimatic Cylinders
Bore sizes: 5/32 up to 1 1/8" Bore " Only problem is they do not make mounting hardware for the really tiny ones.

My testing shows that the Midifan at around 1400W has an eflux velocety in the 150 MPH range so he can probably get his upwards of 110-130MPH on a fast pass depending on the installation and airframe.

This is the begining of the intake molds.

Thats looking pretty sweet! With running the dual fans do you have to run two ESCs or can you get away with one since both motors should be in sync together??

I will run each motor on independent Castle Creations Pheonix 60s. I have not heard of anyone using one esc for two motors with success

You can run one ESC with 2 motors for the smaller motors like 280's and maybe 300's, but I wouldnt run one ESC for something like this, too much juice going thruogh that thing for 2 motors. I am running one ESC on my GWS A-10 and it works fine.

That is interesting because it does save lots of cash. Castle Creations recommended getting the larger speed control when you use higher lithium cell counts. This motor setup will only draw 45 amps, but at 6s that is the limit for the speed controller you want to up from the pheonix 45 to the 60. I am done working on the jet now in my current house until I move into the new house, this is very frustrating because the jet is near completion. It still should be flying by the end of the month.

So that has to be the best F-22 I have seen !!!!! and edf retracts.....etc.... how much I need to start saving .....plz tell me you are going to sell some kits!!!!!!

one word....NICE!

I plan on making and selling a few myself and then I will probably sell the whole project to a manufacturing company. First things first, get the test flight out of the way by the end of this month.

Any idea what the kit will cost ? and what it will come with ? any way thanx !!!! cant wait till you fly!!! The retract doors look so cool ...!!!

I would love to have the exact price now but it is impossible to figure right now. It will not be the cheapest jet out there because of the construction costs but I want to make it affordable for everyone. The the fuse in the picture is straight out of the molds, the only thing I have done is trimmed it up and cut out the retract doors. The next milestone will be the test flight and that is all I am really concentrating on right now. After that the jet in the pictures will be for sale ready to fly.

you have a very nice finishing for something coming strait out from the mold...did you used gelcoat??? usually, when I use epoxy, I have some small air bubles problem when using vacum....
