It's a new ARF for the Tokifan, I have one inbound from Japan...check out the video on the link above, seems to fly nicely!

ET, any idea on general availability? Looks much better than the other Toki offering. Thx, Rick

EASYTIGER

My Feedback: (119)

No idea, I assume it is out in stores in Japan, and can be gotten from the Toki website...
I don't know if MRC will carry it here in the states.
Which other Toki offering, the Dj-3?

Curtis, that big tuned pipe could slide easily away from the header with the engine vibration... and that could hurt bad someone if it fall off the plane in the wrong moment .... I guess that it would be better to start flying better engineered models, like most helicopters are or turbine airplanes !

Hey Enrique,
Aren't there rules about crossthread sarcastic insults?

Nooooo,, Curtis is a good friend, and this shouldn´t can be taken as a insult. this is just poking some fun on him in a multidimensional crossthread ciberspace!

The pipe is aerodynamically designed to spin down gently and safely if it comes loose. The only way it could hurt somebody is if it accidentally got enmeshed in the rotor blades of one of those toy model helicopters, and caused said helicopter to exit the rather nominal control those things exhibit under even the most optimum conditions, and said heliwhopter scythed its way through a bus full of children. Now THAT kind of thing scares me.

erbroens

you haven´t foresee the worst case scenario... what if the schoolbus was turbine powered and the debris hit the fuel cell and ignites a unstoppable fire that burns all the trees in the world?

You know...I had really not thought things through that far. My wife is always accusing me of stuff like that, like if I leave a window open, and the window screen falls out, what if the cat decides to walk along the windowsill, and then there is a sudden gust, and the cat falls five stories...I just open the window and just count on the screen not falling out, without REALLY considering all the ramifications.

When the Ducty arrrives from Japan, I will send it right back. I like trees, I like busses...better to play it safe.

ET, was referring to the DJ-3. Have one I haven't finished yet. Tried to get the F-1 that you worked on. Think there is a market for these smaller airframes if they just get the designs and power issues resolved. Rick

EASYTIGER

My Feedback: (119)

I think the more powerful engine, still under development, will make a huge difference. The problem really lies in the fact that it is hard to design a small enough airframe around the 95mm fan, with only 2.2 pounds of thrust or so. Nevertheless, have managed to get some very nice performance out of the DJ3 and the A-7, very nice. But more power would be nice!

Consider fixed gear or air retracts for the DJ-3, the stock setup of mechnicals is not very good...

Hi, what size is the new Toki engine? Are they making a new fan for it too? I am making an F-16 for the 18 size Toki fan, with fiberglass fuselage and foam wings/stabs. I am planning on making it very light, but we'll se when it's done

volkan

so you had the same nightmare!!!

erbroens

Nah, almost no bad dreams here... it takes a lot of effort and Jet a-1 to burn a single bunch of trees! LOL.

Enrique

My Feedback: (119)

A 26. I think it's a variant of one of their heli engines. May be a whole new unit, new fan. So far, not on the market...

Your F-16, if you can hit three pounds...easier said than done!

Oh, I dunno! Did you see that thread where Luge Bob burned that Christmas tree?

Guys

We have just got the Ducty 20 in the UK, looks like fun with the pull starter and compact size.
I may even modify one for my Lambert T32 turbine.

I know it should be possible to make it weigh 1500 grams, if it gets lighter, I would be very happy, if it gets heavier I will be disapointed [] But a bigger engine would help the situation. My F-16 will be at approx 1/11,5 scale with 122,5 cm from nose to tailpipe (125 cm overall) and 80 cm wingspan (all scale dimensions, also air intake). I am going to do everything to keep the weight down

erbroens

Well, technically speaking , a dead tree is not really a tree. it is just firewood .. and with this terminology what would you expect to happen? somebody needs urgently to change this english
word.

So...a dead baby harp seal is no longer a baby harp seal, but just good eatin'?
1500 grams is 53 ounces. Will fly fine at that weight, if you can get it lighter, so much the better. Not easy...tailerons rather than ailerons helps a bit.

I'm glad to hear Motors and Rotors is carrying this, I want to do the review thing, but unless people are able to get access to the kit, it's no good. I got mine direct from the factory through some connections. Ordering from Japanese hobby stores(I think they have it?) is a pain for most people. It would be perfect for the Lambert. If you can find one of the out-of-production A-7s, that would be even nicer. They have an A-4 under development, don't know where that stands...what will the pricing be on the Ducty?

born_rc_fan

Yupp, that is my oipinion too, that it will fly good at that weight. And yes, tailerons have been one of my criterias on the plane to make it light. Will also use HS-81 servos from Hitec, since they are very strong considering the weight. No rudder also, but off course a steerable nosewheel, so 4 servos in total. Will have fixed landing gear, but every wheel will be spring loaded A high goal for me would to make it 1300 grams Read that you had som experience with the A7 corsair and the Toki 18 fan, how was it to fly?

EASYTIGER

My Feedback: (119)

The A-7 was the best flyer out of all the Toki planes, the most fun. Not fast, it kind of seemed to hit an aerodynamic wall about about 60mph, but fun and steady and reliable. Highly recommended.

The weight, it's funny how it adds up...the landing gear adds about six ounces, minimum, but what else are you going to do? You don't want to risk hand- or bungee- launching it. My F-35 came out at just under four pounds, if I remember right, but I had PLANNED, just like you, to be lighter, but the weight just seems to add up! Still flies fine at that weight, much less drag than most other Toki planes, considerably faster than most of the others. My friend Joe Beshar did a Shrike with a takeoff dolly and the Toki stuck on top, that thing went like stink, a good 90mph, if not more, but it don't look like a real plane, and that's cheating...
Consider a takeoff dolly, it's actually a decent solution if you engineer it right.

born_rc_fan

Wow, 4 pounds, that was somewhat more than I am hoping for, but it's like you're saying, suddenly the weight adds up, and the plane is 20% heavier than expected..[:'(] But the good news are that your plane still flies good with this weight, and that is great news for me in case I'm not reaching my goal weight... How big is your F-35? How is it constructed? I saw a picture of it on your gallery, must say it looked good! [sm=thumbup.gif]

My Feedback: (119)

It's the Oakdale F-35, it spans around 36", very similar to your F-16 in many respects.
I think there are some threads about it around here, if not, it will be in the next RCJI magazine.
I have a foam Hawk on the way from Hong Kong, spans 40", for a 95mm electric, it looks like it may be the bee's knees for toki power, we will see when it shows up...

Dave, unless I'm blind, didn't see anything yet on your website on the Ducty 20. Any info on pricing yet? Since I don't have ET's worldwide connections, would like to see what we can arrange. Thx, Rick
