Swindler


I designed, built and flew my own speed 400size Deciever some 10 years ago. Those days, many people are amazed with the performance of small electric racers powered by the puny 6V speed 400 brushed motors. But the prices of these tiny moulded composite airframe then was very difficult for one to swallow, which easily cost many times the prices of the powerplant itself. And so, the deceiver is born, just like many good old fast balsa designs, if you remember the "Pocket Rocket".

I finally folded the deceiver wings in air after about 2 years of flying, even on brushed motor. Ever since, I had re-designed the rebuilt many versions of the Deciever, including the one I own now, which are significantly beefed up to take the near 300 watts of power of the brushless setup on 3S Lipo.

Of course, I don't use them for racing at the moment and I am not restricted by any limitations of the setup. Seeing so many grossly overpowered 'dirty' foamies zipping across the skies of our local field, I suddenly feel the need to re-educate this people that they don't need to use nuclear system to fly fast planes.

The Deceiver does that pretty well, but I was also toying the idea of changing its tail to T-tail, to make it look more 'marketable'. Frankly speaking, I don't think the T-tail version will roll as axially as the original standard tail one, but I think it really look much better. To identify the new design better, I named it as "Swindler".

I have flown it for the first time today, and I've to say that it flies very well, just like the previous design, only a little more untidy in 360 rolls. These planes have very wide speed envelope that allows it to be zip across the sky as fast as those 'dirty foamies' at a fraction of thier power consumptions, and yet are able to slow down comfortably for good landings. The motor used is some cheap B2040 3000KV inrunner designed for EDF, and paired up with a Hobbywing 30A ESC. The battery is just a 1300mah 3S 25C Lipo, a relatively cheap trill.

I am in the process of touching-up the plans and if anyone is interested, I'll be glad to share it free-of-charge. Re-live the old days of fast balsa and to hell with foam parties!

Hi Wastegate,

I'll need your email for sending the attachment.

Hi Babasmurf,

Nice model you got there. When I found the suitable powerplant system, I'll be designing something about the size of your racer.

Here are some of the pictures taken during the wing construction. The wings are basically balsa and foamcore sandwich structure, with CF strips and glasscloth reinforcements. The wing skins are 1/32" balsa and the wingtips are solid balsa.

The ailerons are cut free from the wings and faced with balsa caps. Their torque rods are offset to allow the rigging with a single flat mounted servo.

The fuselage is simply a box structure with triangular gussets glued to the corners to allow some roundings. The vertical fin is built-up together with the fuselage construction itself.

I forgot to include the detail on the T-tail mounting in the plans. The tip of the vertical fin has a strip of 1/8" balsa stick glued on each side, before being carved and sanded into fillets. This will increase the contact area between the fin tip and the horizontal stabilizer. I dug up some balsa at the centre and filled them up again with epoxy/microballoon mixture. This will provide a hardpoint for the stabilizer mounting screws.

The horizontal stabilizer is mounted by 2 small wood screws, but after covering, I apply some epoxy as well to make the joint stronger.

AUW tips to around 13+oz, with 2 HS-65HB servos, a Schultz receiver, motor/esc and a 3S 1300mah Lipo pack.

Very nice work
I now have AutoCad to view the drawing but can't work out how to print it out in A4 tiled?

You'll have to use the "window" function in the printing menu to crop the area you want to print. If you need, I can send another copy with the A4 outline 'tiles', so that you can use them to select your print area.

Yes please.
