About the only photo I can find of it fitted ... it glues to OUTSIDE of fuselage set into a slot. Take care to not glue the sliding pin etc.



Heres the ESC stick retainer :



Painting ....... all I say is make sure underside is clearly different to top ! The Red Arrows white Arrow underside on my first T45 I have is incredible ...

Nigel, why does your fuselage look all busted up and why did you embed the ESC into the foam where it can't properly cool? Just asking....

[Bill G]

I bought a few of those HK latches, and had the lever break on one. Being already installed in a favorite Macchi M33 scratchbuild, I managed to repair the lever with a piece of CF spar and reinstall it, rather than mangle the battery door to remove it. The next time I used one, it was installed such that the the lever did not have to move far (short pin engagement) so that the lever wouldn't break off. The spring that they use is stronger than necessary.

Because it is beaten up ! It's been repaired so many times ... the nose is not original - that's about the 4th it's had in about a years use.

The ESC is actually in correct place ... in the EDF duct in a purpose channel in top section of fuselage.

The usual thing that happens is the plastic lever moves on the pin ... needs a careful application of tiny drop of CA to wick in to cure.

I think that happened with the other one I had. Add that to the breaking lever experience, and you have high HK quality.

I'm no HK employee etc. - but to be honest - all similar latches I've had whatever source have had similar happen. Mixing plastic with metal is always a gamble !!

BUT - given the security of the latches - I can live with it ... you only need to lose one hatch or battery cover !

One thing I do to make the pin slide more easily ... I use old ballpoint pen ink tubes cut to length for the pin to engage into .. this removes the foam friction and also keeps 'hole' clean and round.

i got my Mig 15 up and flying awesome ! i got a T-45 which i cannot get to fly at all......same set up ?

could i have a faulty esc maybe

[dahawk]

Brick,

That seems odd. My T-45 flies great and she's taken a beating. What's not working? No power?

If you describe what's wrong - we will all try to help ..

The T45 is a steady flyer that is probably the best all-rounder of the 50mm's ... good wing-area, reasonable battery capability, good ducting ... It will never be the fastest, but once sorted will reward with good steady flights.

I have 2 50mm's, also a 64mm ... all 3 are excellent.

when i hand launch the mig , nice little toss...it climbs very nice and gets going

when i hand launch the T-45, it acts like it wants to go....but just belly lands, (it dosen't nose dive), just acts like its not getting enough power. i calibrated the throttle with the esc. when i get on the throttle it sounds very powerful. just won't get up there

i'm using 1000mah 3s 40 batts....launching at full throttle

[solentlife]

Ok - lets try a little test ...

Do you have a kitchen Digital Weighing scale ?

We are going to check out the thrust levels of the T45.

Set up T45 with it's battery etc. just same as to fly. Switch on scale and stand T45 on it's nose on the scale. Read the model weight. Now zero with the T45 still standing on the scale .. Now while steadying the model run up the motor to full .... noting the thrust reading.

Once you have those two readings ... model weight and max thrust ..... post them here ...

I have to try and remember ... but I think my T45 on a 3S similar to what you have was about 380gr ... that's all stock. My later modified is about 700gr !! But that's another story.

Nigel

[Brick]

thank you Nigel...i will try that tomorrow ! also gonna do the Mig to compare

[solentlife]

This may interest you .........

Real Cold war Mig ...

My wife next to one ...



Note the wing and the anhedral that is missing from models ! ..



It's also a lot smaller than most people imagine ...

My Mate Andrejs ...



I offered to buy it ... it's had engine removed but rest is intact ... it's slowly just falling apart at entrance to an ex Soviet First Defence strike Airfield. But they wouldn't sell.

that would look cool in the front yard !

as for my T-45....turned out to be a bad esc. got a new one in there today. it screams with power now !

[dahawk]

Way to go Brick !

Figured there was something amiss.

I have about 200yds of front approach to my house ... so plenty of room to put it. I reckoned to elevate it on poles. But no deal ... Shame.

Does cross my mind whether to create a fake one in wood / foam ... !! Can't be that hard.

Back to the T45 ... way to go ! Now enjoy !!

The T-45 seems to be, by far, the most popular EDF in this series. Or at the least, the most talked about model in this thread. I like everyone's passion for this plane!

I'm an F-16 brat, and am amazed at how easy it is to hand launch, fly, do tricks, and land.

Can you imagine how blown away people would be if we took these little jets back to 1985?

Keep up the great thread everyone!

I think the T45 is possibly the sweetest looking of them all .... nothing radical or out of synch with it. It also has a good wing area and carrying ability. The canopy is large and with little modification - you can carry a serious battery pack. The CoG range on it is much larger than many realise .. it tolerates easily a heavy pack up front and still flies clean.
it will never win any races ... but it's a smooth flyer for it's size.

Yes - I have 2 50mm's and 1 64mm T45 !

Bunk,
Nigel has mentored many of us here on the JPowers 50mm series. My Red Arrows T45 is nearing retirement.I also have the F16 and Katana plus the Phase3 F16. One nice thing about the JPowers series is the interchangeability of common parts. While one is in the shop for airframe repairs, I move components over to the other. Have spares but it's always nice to use what you know works. I've readied the F16 for more abuse.She's faster than the T45 but not better .
Can't go wrong with these planes with the notable exception of the Grippen which I hear is a dog. The Katana has yet to impress me.

Good luck,

Hawk

Thank you for the compliment ... but there are far better people with these than I .. I just pass on what I find as I fly them. I'm a bit daft about getting max speed as well !! My solutions are as budget as I can get them ... not best by long chalk ... but they usually work.

.......She's faster than the T45 but not better .

I keep looking at the F16 ... but that battery location throws me of - I would want to use my 1600 4S in it as well ....

They really are good for their size ... far more steady in the air than many other models of similar size.

The Katana seems to be receiving mixed but favourable reviews ... but one comment I think goes a long way in explaining this - the too large an exhaust outlet duct. Fine for thrust and clearing air from the fan ... but not so good for speed ... mmmm it looks like a mini Stinger as well to my eye.... and for just a few $ more - I can have the Stinger with it's 64mm unit etc. and push the adrenaline envelope ! Sorry but Katana is not on my priority list .. but the Screamer is edging onto it - but for pusher conversion !! I need a new record breaker since the Parkjet has been discontinued.

Nigel

[solentlife]

I find it interesting that Hobby King do most of the 50mm series but not the Katana or Screamer ... wonder why not ?

I made the mistake of buying the Gripen without doing my research... I quickly realized I made a mistake but it was too late to cancel my purchase (ebay).. It arrived in a smashed box and has a bent wing. It's a great looking jet but apparently has some major COG issues (as you mentioned). I haven't bothered to put it together yet, as I'm having too much fun working on upgrading my F-16s and an F-22.

I'm kicking myself for not buying a T-45 instead of the Gripen

[Brick]

i'm lovin my 50mm T-45 so much, fixin to get me a 64mm

Exactly what happened to me ......

I bought the Lanyu T45 64mm kit of Hobby King at $29.99 ...........

Fitted a 2815 4300kv Turnigy EDF motor to the supplied EDF unit - perfect fit.
Flew it on 3S 2200 ... then threw in a 4S 1600 .... nice smooth flyer. I left of the wheels etc.

Later I removed the elevator servo and fitted separate smaller servos at back end to direct link to elevators. This allowed me to up to a 4S 2700 Zippy Compact .... now she MOVES !

Excellent machine.

T45 64mm 23-11-12

If any tips etc. wanted for the Lanyu 64mm ........... just ask - there is also a thread here and on RC Groups I did ...

Nigel

[dahawk]

Made it to the field today and flew the F-16 for the first time in a while. I pinned the ailerons and am just using elevons. Ran stock with the hyperian 3S 850 30C.

Flew okay but no adreneline rush. Roll rate was awful, even on high rates. Not as exciting as the 64mm Phase 3 Ef-16. Maybe I have too much expo programmed ?
