Bloody HK still no replacement T45 kits ............. really annoyed !
Have another ESC now - so will rebuild AGAIN !! this time the beams have saved the nose section but she's broke away inside where it tapers to create the dual ducting. Wing has come away - so allows me to get inside nicely to repair all that area. She'll be flying again later today .... IF weather holds of.
Sorry to head about all your troubles. Best of luck!
Seems doomed !! When putting EDF unti back in - I thought give it a test first .... fan caught an edge of bench when I ran it ... snapped shaft.
So - ok - I still have the original 50mm unit. Fitted that with packing to hold in enlarged bay.
Went flying .............. 20secs into flight - she died.
Collected model from field. EDF unit had twisted in fuselage, shorted the cables on stock motor.
I straightened unii in fuselage ... test ran it ... fan shed its blades !
Buy it now on Ebay - new inrunner motor 4850kv for the 51mm as shaft not available.
Very nice lineup ! Dang, they look brand new ! My F-16 arrived yesterday from BH but I have not set it her up yet. iS your the Phase 3? DOdes not look like the Skyangel . Anything I need to know ? CG? aileron/elevon setup? Expo? DR? Launch? I hear the F-16 is a bit faster than the T-45. Same flying charcteristics?
mine is the Phase 3 EF16.....only tailerons on it. gotta do a little mixing on the tail setup...i have a DX7, i just use the Delta wing mix. no main wing ailerons or rudder. the tail wings/fins do all the work.
Skyangel T-45 uses elevator & ailerons....no rudder
they do fly a little different. Phase 3 EF16 is quite a bit faster !...but you can fly it pretty slow and it won't really stall
Setting up F-16. Am I correct in assuming the battery goes in the far forward cabin? If that's the case, doesn't leave much room for anything more than a 850mah 3S. Looks like CG is 60mm back from LE break. Put a 1000mah battery in the rear cabin as it fits and the CG seemed okay.
Been wrapping the forward fuse and nose of the T-45 with a very warm, wet towel off and on. Seems like the bent foam is coming back to form, slowly...
Might have to give her the imbedded popsicle stick along fuse treatment but trying to avoid the hastle if I can.
Looking forward to flying this weekend except the temp is right at 100F the next few days. Whew !
The side beams are good - BUT note that crash damage is then transferred further back to the fuselage joint inside the intakes.
Here's the last rebuild of the Mini T45 .... (yep a massive rebuild that many I think would have 'binned' the model !! )
Here's the 51mm edf unit with a 4850kv inrunner fitted ...
Note the mounting side beams cut away from the shroud ....
Here's the fan in parts and the shaft adaptor to fit rotor ..
Well worth the effort to fit ... it doesn't give a great increase in speed, probably 4 - 5kph ... but the power curve is nicer in flight with excellent throttle response from the higher KV motor and 7 blade rotor.
Unfortunately the inrunner motor snapped it;'s shaft and I wait a replacement from ebay .. (it was my fault it snapped - not motors). The 50mm fan will get a 6 blade rotor replacement from the odd sized 50mm unit from HK. I'll only use the rotor as the HK unit is a 19mm motor fit ... strange size !! The 6 blde will make the stick unti better I reckon ... maybe better amps than the 51mm ?
Foam is literally repairable to ridiculous levels as shown here but I prefer wood actually. Foam compresses and always suffers whatever you do. Wood breaks but you don't have to muck around expanding compressed foam etc. You can cut and splice and have a much better repair at end.
But then again - I'm an old-fart modeller from days well before foam models ! Only foam we saw was packing !
I like foam for it's lightness and variety of quick to air models .... but wood still has an attraction for me.
There is another factor - foam lends itself to the EDF range in it's being formed into frames that are light, good ducting etc. Having built wood DF in past - I can say foam is best in this !!
Off to Wal-Mart tomorrow to re-load on some epoxy. Had one good flight with the T-45. Roll rate is still very sluggish. Had a buddy toss it. All good.
Later, I attempted to hand launch it myself. Not so good. Managed to roll her over on her back and crash. Broke the fuse just in front of the intake. Easy repair but I'm frustrated I'm having trouble hand launching on my own.
Hope to maiden the F-16 tomorrow. Battery compartment is not nearly as deep as the T-45. Tight fit.
My new T45 kit is winging it's wqay as we speak ............. the 50mm I've decided will go in it along with a higher rate motor ... the same 4850kv I use in the 51mm.
Why ? I may ressurect the old T45 and fit the 51 in her again ... have a trio of Hawks .... then later may invest another $15 in second 51mm and 4850 motor. That really is an excellent combo in this size.
BUT make sure the ESC is rated at 35A or more ... better fit a 40A that can also take a 4S ...
Had a pretty good day. Repaired the fuse on Red Arrows in the AM with 5 min epoxy and that did the trick. Re-taped the nose for crash protection. She's starting to look like a lady who's had too many face lifts!
Since I'm still pretty pathetic when it comes to hand launching, a guy assisted and all went well. I need to get better at this. I also need to adjust the throws to gain a higher roll rate. My F-22 profile foamie pusher prop jet can outperform the T-45 so I want to see some improvement.
Was not comfortable maidening the F-16 today. The down side to this plane is it's very shallow cabin. Not much room for even the stock 850mah battery. Had to carve out the bottom side of the canopy to allow for wires to sit on top of the battery and still be able to close the canopy. It's still bulging. Will probably still need to use packing tape to hold down.
Need to get the throws set properly and radio dialed in.
Look forward to next weekend.
Nigel, sorry to hear to must return to the Middle East on short notice. Seems like you just returned.
I'm seriously considering a modification to the 50mm series ... having already tried the wood beam insert. That is marry a wood nose section to the foam main fuselage section.
It would increase battery box size, increase strength of nose, be easier to repair and stay cosmetically nice ..... but leaving majority of model in foam and light.
Why ? Foam has to be substantially thicker than balsa to get the required stiffness.
Dahawk ... launching the T45 .... my way is hold it by fuselage underneath at trailing edge of wing like playing DARTS... at shoulder height ...... Open up motor to full and then as in darts give it a targetted level throw .... if trimmed correct, she should dip and bank slight to left .... slight touch of right aileron and hint of up should see her start to correct and climb away. I do not apply such correction at moment of launch as I am right handed launcher and fly mode 2.
Yes - job is certainly getting in the way of my hobby !! But I have to pay the bills.....
Okay, I'm frustrated. For the life of me, I cannot get any of my small batteries to fit inside the the cabin of the F-16. I have a range from 850-1600 3S and few 4S' compact zippy's. Cram it in and with the wires and I still cannot keep the canopy closed without taping it shut. Am I missing something?
So, I came up with a possible solution. Cut a hole in the floor and suspend a dropped platform made from popsicle sticks. I could pre-fab this then epoxy it in place. Only need about a 10mm drop. Thus, the battery will sit slightly lower and even gain some cooling from the intake. The esc wires can then sit over the top and I could get the canopy to closed.
