Default Setup for Kyosho T33

Hi guys! I found a NIB Kyosho T-33 the other day, and having flown a few of these many
years ago, I must say I really liked the plane, but of course it was really underpowered!
Has any of you set it up with a hot brushless motor, a new fan and LiPo's? Do you have any
recommendations for me? Any suggestions will be appreciated!

Thanks!

I have flown mine for years with a 3 cell 3200 kokam pack with the Astro flight brushless setup they sold for the kyosho fan system. Do a search and you will find many different setups that will work great.

I hopped one of these up back in '03.  I used the stock fan, a Mega 16/15/2 and 6 Gold Peak 3300 NiMH cells.  If I do another one, I'd go with the either same motor or a HET 2W and a 2S LiPo set-up.  It pulled around 31 amps at full throttle.

I agree with rob, a mega 16/15/x on a 3s or 2s is the best option. You easily reaches twice the thrust of the stock ap29 at half the current. A perfect match a the t33 is't strong enough for alot of power.

The stock fan is no that bad actually. The stock motor needs about 40A to made 320grams of thrust, while my Hacker B40 8L used only 17A to make 600grams of thrust. This was back in 2001 useing 7S round cells.

Motor sucks big time but the fan is not that bad, but still if seting one up today i would probably put in one of the newer fans with more blades if I could find one in the right diameter. is't the ky fan like 75mm?

Yes, the original is about 74 mm outer diameter, I just ordered this combo: http://shop.rc-electric-jets.com/RC-...DF70-1P032.htm
which is 72 mm outer diameter, should fit nicely and is supposed to give 1.3 kg thrust with a decent 4S package. I will keep you posted on how this works on my old fighter!

Someone once told me that it will not handle more then 160km/h which sounds resonable so don't push it :-)

I agree with Henke on the power issue.  Back when brushless motors began hitting the market, some pilots put Wemo 609 fans in the T-33's and found out the hard way the wing needed carbon fiber reinforcement.   Also, more poweryields disappointing results in the speed department.  This is a draggy airframe with poor internal ducting.

The key to this jet is keep it light.  I really recommend staying with the stock fan and using a Mega or HET brushless motor.  With a light set up this plane is a wonderful flyer.  Scale like speed and easy to handle.

Default RE: Setup for Kyosho T33

I'm not looking for too much speed, just nice, huge loops and verticals. The first T-33's I had back in the day were
modified with brushless motors and up to 10 NiCd cells, and they were HEAVY! But they still flew nicely, I cleaned up
the ducting a little and flew them smoothly, on one of them I had a record of 17 minutes in the air, more like a glider,
I guess, but fun back then! So I will keep the throttle down at all times except for takeoff and verticals!

The Kyosho fan is/was not built to withstand much power, certainly not close to currently attainable power levels with brushless motors. Best to limit it to approximately 500watts maximum if you want to keep the blades on.
If you really want those huge loops, etc. you would be better off to go with a WeMo MiniFan, Mega 16/15/2 on 3s or 16/15/3 on 4s type setup. Reinforce the wing with carbon tube spars inset into the bottom of the wing or just use filament strapping tape span wise.
The minor difference in fan diameter is not going to hurt preformance.

Default RE: Setup for Kyosho T33

Here's the setup I chose, with a 4000 mAh 4S 40C LiPo pack from Hobbyking, I will reinforce the wings with carbon tube spars and
see how that works out - should be a LOT better that the original setup! [8D] I also bought a much lighter 2650 mAh pack for shorter
flights.

Default RE: Setup for Kyosho T33

The RCLander 70 mm unit and controller arrived today, I tested it with an older 4S package, and what a great combo!
No vibration, smooth and VERY powerful, a great value for money! My old 4S package couldn't sustain full throttle for
more that 2 seconds, new packs are ordered from Hobbyking, this will be a great upgrade for the T-33.
I think I'll reinforce the wing with a carbon spar, other than that I will just fly on 70% throttle and in my usual, quite
soft way, but there will be no lack of power for takeoff and verticals!

Not trying to hijack the thread, but I've got a NIB kit for $175 shipped in the lower 48. If interested, contact me via PM. Thanks!!

The T-33 is finished, thrust seems very good, but I am still waiting for a much better battery pack.
The color scheme is pure fantasy, but should be easy to see against any kind of sky!
Maiden as soon as the battery pack arrives!

I have maidened the T-33, lots of power on a 40C 2750 mAh 4S package, about 4 minutes air time, loops as large as I want,
very fast and real fun!! Second flight was with tip tanks mounted, flies just as fine and looks fantastic in the air! This was just
what I wanted, I will fly it with a 4000 mAh package when I have someone around who can throw for me! Very happy with this
combo!
