Good work! Can you give more details of the construction and whether or not you have a source for plans?

Thanks!

BTW, Visit the Toronto Aerospace Museum in Downsview for the BD-10 that was being touted as the new jet trainer for the RCAF before they decided on the Tomahawk variant.

Thanks for the kind words guys. I drew up the top view myself from a 3 view drawing and made changes to accomidate the fan. Construction is little more complicated than the Nano Bandit but not too hard. Its just 3mm depron and some styofoam for the canopy and nose. I used a cone program to make the tailcone and turtle deck. It has an 18" wingspan and is just a little longer than the Nano Bandit, also has a wider fusulage. The ducting could be a lot better but for now I think it should work. Just waiting on some new fan rotors to come in.

Well after building a NanoBandit I decided I wanted something around the same size but more scale so I came up with this. Haven't installed he gear yet but the empty airframe weight is only 1.3 ounces. I am going to try to get some plans up for you guys after I test fly it. Enjoy :)

Hi Speadfreak

1.3oz for a total airframe - how large or rather small is it???
What is it made of?

Do you use any special process?

Have fun with fans

AWESOME best looking nano I've seen yet, hope it flys as good as it looks.

Looks like I'll have to get back to my nano and finish it off to make room for this one.

Here are some more specs on the BD-10

Wingspan 18"
Length 21"
Empty weight 1.3 ounces
Construction 3mm depron and styrofoam

Will use a Feiago BL motor and TP 730mah 11.1 volt pack. Going to try to draw up some better plans and redesign the ducting for more efficency.

Well got my rotors in today and installed all equipment. All I can say is wow, almost 1:1 thrust to weight ratio. I just need to find my CG and wait for the wind to die down. Hey guys the top view/ plan I drew up is a BMP file. Can you all deal with that? I have autocad but not on the coputer I am using now. If anyone wants the file I will send it to them and they can zip it up and post it here. Also can somone give m a cg estimate? Thanks.

very cool..I have been looking for a first foam jet to build.I think this is it. I always liked the orig.(full scale) but unfortunatley it likes to kill people.two company presidents. One died when he had a split flap on finale(one up one down) he attempted to go around and when he applied power the plane rolled into the ground.the other had flutter and tore the tail off.

Speedfreak

Feb 19, 2005, 11:21 PM

Thanks for converting it Eric. Yeah its too bad about the real BD-10. I don't think we'll have to worry about those problems with this though. I am really glad everyone likes it. I maidened mine today. Final flying weight was 5.5 ounces. Not a speed demon like some of the other nanos but it flys well and looks great. I'll build version 2.0 a little lighter as I used epoxy to put this one togather. I would love it if someone could come up with some light ducting for this so we could up the speed. If anyone has any questions just let me know. Have fun!!! :)

beanie

Feb 20, 2005, 03:05 AM

looks great speedfreak!
i was wondering if you think its possible to make it using blue fan-fold (ie, 1/4in) instead of 3mm depron. would it add too much weight?
thanks

Speedfreak

Feb 20, 2005, 08:03 AM

Hey Beanie, you might be able to do it but you'll have to change some dimensions to get everything to work. I'd say go for it and see what you come up with.

I am going to build Version 2.0 with ailerons. Tailerons work but just don't handle as crisp as it will with ailerons.

Well redid version 1.0 with ailerons instead of building a new one. Whole different airplane with much more crisp handling. Now if we could just up the thrust with some better ducting we'll be rockin' and rollin'!

Speedfreak

Feb 21, 2005, 07:03 PM

How much thrust is everyone else getting on their EDF40 fiago combo. Just checked it with the scale and only got 3.5 ounces?

AirX

Feb 21, 2005, 08:38 PM

The 5800 gives almost 6oz with out the ducting, the difference between the it and the 5300 is about 1oz on my test stand so the intake ductin and the outlet ducting tend to take a few oz away. Look for 30% reduction of thrust.

Do remember it will need a heatsink even if it is the one that comes with the GWS fan. It will run hot without it.

:cool: Are you going to repost the pdf for the aileron version? By the way this is way cool! Can't wait to start building it.

Speedfreak

Feb 23, 2005, 01:00 PM

No I don't think I will post anything on the aileron version. It is really simple just a servo in the center of the fuse and two thin wire snakes going out to the ailerons attaching to control horns. If you look for the thread for the Nano Bobcat and look how he did his ailerons these are done the same way. Then for the elevators just run a piece of wire through the exhaust tube from one to the other to connect them togather and run off of one servo. Breezer I am going to send you the origional BMP so you can start building.

Breezer

Feb 23, 2005, 01:43 PM

Could you give us some more pics ?

Speedfreak

Feb 28, 2005, 10:36 AM

did some experimenting with the ducting over the weekend and found that making smoother ducting for the intake made no difference in performance. However I think the second one I will build cn be up to half and ounce lighter maybe even less. Prototype was put togather with epoxy, next one will be with CA or something even lighter.

Cyberman

Feb 28, 2005, 02:46 PM

Where might one find a 12mm dia. heatsink? GWS makes one for the motors used in there 40mm and 50mm EDF units the RLC-12 and RLX-12. You can find them at any place that sells GWS stuff my guess.

how did you make a full cylinder cone with the depron? is it that easy to use. I have only used fanfold.....

Speedfreak

Mar 05, 2005, 10:41 PM

to make a cylinder with it you need to put creases in the foam so it don't crack. I am going to try a little heat to bend it next time

I started mine today, not sure how im going to make the cylinders, might use transparency paper

Speedfreak

Mar 11, 2005, 10:39 PM

To make the cylinders you just crease the foam with the edge of a ruler or something then roll it togather and either glue or tape it togather. On the tailcone "where the fan goes" I taped it togather and glued into the airframe. I used the same method on th turtle deck for rolling the foam, but didn't need to tape anything becase it just fits into the airframe and gets glued. Still waiting on some new foam to build 2.0. :(

mcdonald77

Mar 12, 2005, 12:16 PM

Can you tell me how you connected the tailerons? I am looking at mine. I am going to use alerons, but do you think a rod going across the rear duct would hinder the thrust much? I would rather have the elevators connected to each other, then I cut down on servos.

Speedfreak

Mar 12, 2005, 12:41 PM

Thats what I did on mine, just used one servo to drive the elevators and a small wire going though the duct to join them togather. Didn't hinder the thrust at all.

Speedfreak

Mar 28, 2005, 03:32 PM

Installed gear last night. Version 2.0 is almost half an once lighter. I did cut a cheater hole in the bottom and it gave me probably a half ounce more thrust. Here are some pics of version 2.0 First pic is both BDs togather, and the rest show more construction details. The new one looks smoother because I heated the depron up to roll it so there are no creases like on the first one.

Speedfreak

Mar 28, 2005, 03:35 PM

Little side note: The fins on the plans are too small, I am sure they will keep it pointed in the right direction but they just don't look right. I will try to get a decent shot from the side so you can cut some that look right.

Just a few questions; what ESC/battery do you use?
How does it generally fly?

Dave

Speedfreak

Mar 30, 2005, 10:31 PM

The plane flys very well. It doesn't have unlimited vertical but can climb out at about 45*. The battery I am using is a thunderpower 730mah 11.1 volt pack and a pheonix 10 esc. Good luck on your heli fuse, my next project is an L-39 albatros for EDF40 already under contruction. :D

Maidened by BD-10 today! Flew great after I got the CG right. The first couple of tosses amounted to powered glides to a flat landing with no damage. I had to remove the canopy since I had no more room to move the battery further back. The next toss resulted in a great ~7 min...just a guess...flight. It's not overly fast but it's fun to fly. Removing the canopy also opened the fan to a lot more air. So I just need to make a lighter canopy.

Thanks guys. You may notice my post is almost a year old. This gives you some idea of the level of interest in ducted fan kits, a few here and there. It was never a going concern unlike the Assault, Rocket, Little Tiny and Electro Screamer.....

I made up a batch of plastic parts last year and put together the last remaining kits. I then sold them to one guy. I have some bits and pieces but no more complete kits.

If you could get 20 people to order kits at the old price (not even sure they can be made for that amount now), I would consider making one last batch. Otherwise it is not worth the time and effort.

This thread has been very quiet.

Anyone building one or want to comment on their flying experiences?

Considering that I have a Wemotec MF480 with a Mega 16/15/3, I'm almost tempted to blow it up to about the same size as the e-Bobcat (pushycat?) and go for a built-up design.

If you could locate one of Bill Griggs BD-10J kits, you would save a lot of work. In fact he offered to make another batch of BD-10J kits on post #84 if we come up with orders for 20. I'll go for one. Lets see if we can get firm orders for 20. If I count right that would bring the total orders to 4 or 5 if you want 2. Maybe Bill could give us the price for a kit.

Not a lot of details exist -- built-up kit approximately the same size as the depron-based one.

Bill got out of the kit business some time ago, and is cleaning out a pile of his modelling stuff (sorry, but no kits remain). I don't think that he can gear up for a production run, and may not have the inclination.

If you go back through this thread, you'll see that the 20-kit offer was made quite some time ago.

Hi all,

Just thought I would pipe in here since the BD-10 seems to be the topic of discussion.

I made a kit for the WemoTec minfan 480 fan unit back in the day..... The kit was never a big seller because it cost about the same as the Kyosho kit released about the same time. The Kyosho was an ARF. The BD-10 was a kit..... Needless to say people don't build much anymore.

The BD-10 was a nice kit. It flew over 100 mph with a brushed motor and heavy Nicads. It takes a lot of time to make kits. Since the interest is low, I am not inclined to release more kits.

there may be quite a bit of interest now, if you don't want to make kits, perhaps you could sell the kitting rights to a kit manufacturer, someone like EAM.net or EJF.com would love to produce the kits, i'd bet.

So far 3 people have responded or contacted me for kits. I don't see that as "quite a bit of interest". However, I could be wrong, so.... If twenty people PM me with a firm desire for the kit, I will make more.

I sent you my PM this morning Bill. FlyBd is right, this kit will Rock with BL Motors and Lipo's. I think what you have here is a case of "If you build it, they WILL Come" :) heck I didn't even know about the BD-10 kit till two days ago. Personally I can't see how anyone would NOT want to built her, a great looking that will fly circles around some other designs.

I did some searching of the waybackmachine internet archive and came up with a link to the old webpage I had back in 2001. Unfortuneatly many of the links don't work anymore. I will see if I can dig up some old pictures etc.

Just so everyone knows, This was a built up balsa kit with laser cut parts and vacuum formed plastic. It was one of the first slot and tab designs produced (1998) and it was on the crest of a wave. Many people still had to be convinced that laser cut kits were worth while. seems folks didn't think CA glue would stick to laser charr :rolleyes:
