I don't think that ramtec unit will have the thrust for the byron f16, Im getting 12.5 lbs thrust from a byrofan and a rossi 81 was able to keep the plane down to 11 lbs. It does pretty good vertical and flys at about 135 mph.

Hi all, may not be able to do a lot of work but, I have made up a test stand to check the fan and motor operation. The speed controller arrived and set it up and tested. On high timing it was draging 69.5 amps and giving almost 17 lbs thrust. At half power it is drawing 29-30amps and giving almost 11lbs of thrust. Will have to mess around with the timing and check power and thrust to get the best overall preformance. Should fly this little ol' F-16 well as they flu well with only around 11lbs thrust.

Dave, it would be good, but it would be a very long drive just to fly a model. SatNav says 1200kms and around 14hrs of travelling.

HOLY SMOKES!!!!! 17lb of thrust.... now your talking!!!!

Even at your half throttle setting pumping out 11lb thrust on only 29-30 amps is great because my setup will end up drawing 45-50amp to do the same... are you using the UH ESC as well??

I'm thinking i'll be luck to get 12lb. with my setup. which reminds me, i have to put the timing on to high before the first flight.

1200 kms not too bad, well, maybe one day we might come across each other at some jet meet at the half way mark.

Thanks

Dave

Dave, remember that I am using a electric turbine motor, different to the one you are using and I am also using 12 cells. Yes I am using the UH ESC as will as batteries. Started raining down here so I will leave the testing untill is dries up again as I am using the garage door lock to hold it. Don't know how to measure RPM as my tacho won't read 5 blades.

Hey ghost, yeah i remember you were waiting on a different motor, but man, 17lb is monster.... that's got to be well and truly over 1:1.

At least i now know there is another path available to me if i need some more oooph for my old girl if she needs it.

thanks

dave

The Ghost

Dave, it suprised me as well, I had thought about 14lb, so 17 was a bonus. Done some testing yesterday but the rain came back again. Getting 17lb is easy, even when messing around with the timing I don't think that I will better it but may get it with a little less power use. Was running 3200watts on one test yesterday, as the fan is fixed pitch power out = power in, would love to be able to get different piched fans to try.

Looks like you tests were done minus thrust tube....

If you install it onto your rig you will find an it will increase the amp draw, but more importantly the static thrust will increase as well.

On my EZE-Fan trainer, i had no intake lip and no exhaust ducting, when i made these up and installed them, there was about a 15-20% increase in performance. she really moves along now. Now the byron already has an intake lip molded in so it will be interesting to see what difference just the exhaust will have on your figures.

There was a replacement rotor made for the byrofans called the hurricane rotor. these can still be found and i believe they are a higher pitched unit

thanks

Here is our Byron EDF that had a Hacker and now updated with the new Scorpion motor HK-4035-630, HV-110 & 10S-5300 FullyMax - this is one of many different affordable big jet conversions we have been making for over 10 years. we carry all the power system components and can also balance, assemble and test fans sent in to our shop providing a ready to run setup.

Sorry, Short clip.

Thanks Dave, I think that I will stick with the Byron one and save the $$$

Yeah, not cheap....

And, considering that your already at 17lb, if you pump any more power out of the fan, your gonna need to expoy and carbon fibre your wings on!

I'm going to try and go past the hobby shop onthe way home tonight and buy the 8-32 bolts i need for the wing mounts and if the weather is good this weekend, i might have a lot of fun or a lot of work ahead of me!

Thanks

well, today was a perfect day for the maiden of the f-16, but i had a warbirds meet so i took them out instead[X(]

Hopefull this wind that has been so persistant of late will die down and i can get the maiden in.

Thanks

Yeah i know, but a maiden in front of all the boys...

And i haven't been able to get good solid information around throws for taileron only setups so it could become a little interesting.

Thanks

dave

The Ghost

Dave, just set the throws a little more than what they were orignal and go for it. Waiting to get back into the painting, the shoulder is getting better but still can't do a lot so have been building an electric Mopoke and still need to order some more stuff from O'seas, but with the little O'l aussie Dollar in the crapper I think I will be waiting for a while.

Hello all, I am a jet junkie from the U.S. and I wanted to ad some info to the electric F-16 thread. Back in August I flew my glow powered byron f-16 infront of 15,000 people at the D.O.G.S. show in Dayton Ohio and had plans on doing a electric conversion on the byron fan with a Hacker A-50 until I found a better power system. I went through BVM models and purchased a Castle Creations SHV 110 esc and matchhed it with a Neu 1527 4 pole brushless motor and I could not believe the numbers that BVM advertised. With this set up and their electric Viofan wich is a 5 inch unit with 7 blade impeller makes 25 lbs of thrust.... I had to have it. I bought the esc through BVM and built my own unit with a ramtec fan and installed the thrust tube which tapers 5 inches to 3 inches in my CJM mig-15 an old glow powered fan model and weighed it . It is 17 lbs w/o batteries and 22 lbs with the batteries . IT MAKES 28 LBS OF THRUST DURING THE BURST ON THE GROUND!!!!!!!! AND AFTER THE BURST IS GONE IT DROPS TO 23 LBS OF THRUST!!!!! So the batteries are as follows I am using 4 25c 4s 4500mah Evo batteries in series to make it a 16s set up. On the watt meter it pulls 6000 watts at 94amps. I flew the mig and had a 5 minute flight without hitting the cut-out on the esc and landed the jet was clocked at 180 mph or 300 kph . and the verticle performance was unlimited at 2/3 power early in the flight throttle management is the key to make it a winner I am a turbine waiver holder and this is just pure joy to see a edf fly a circle around a turbine. I plan to install the same power system in the byron unit and put it in the F-16 and just throw my head back and laugh. The cost is high but it is worth it to see grown men hold their jaw like they have a tooth achewhen I spool it up she sounds like a dentist drill on steroids.... Thanhs everybody John.

Anyone know where I can buy two Byron fan units?

The Ghost

You can try Iron Bay or you may have to use that Easy Bay where they cheat in the last seconds of the bidding.

I maidened the F-16 today!!!

And what a ***** puckering ride it was! Firstly it looked like a nice calm afternoon, so as i got home from work i threw the f-16 into the car hand headed out for the field. there was a fair bit more wind around than i was expecting, but it was pretty consistent. i taxied out lined up and slowly advanced to full power.

It took full elevator throw at the end of the grass runway to reef her off the ground. it got kinda ugly for 1/2 second, but i quickly shoved her nose down to pick up speed and all was good till i started the turn and putting a little elevator in to get her round. firstly, not enough "aileron" responce in the taileron setup, second, WAY too much elevator and far too sensitive... Consuquently, she ended up standing on her exhaust in a 3D style maneouver. shoved her nose down again and she was away agin. she felt really tail heavy, but the post flight assessment is that she has too much elevator throw, and not enough expo.

I completed a circuit thinking she would snap on me any second, and then flicked to low rate which made her a little more manageable. I gained a little altitude and on the up wind leg, then i suffered a SPCM lock out... she just kept flying away from me, no responce. i started running off toward the model and somehow got a signal in and i quickly brought her round at 1/2 throttle, the downwind leg was really nice, but i just completed the final turn, chopped the throttle and quickly brought her in for a landing...

It wasn't my best landing but not the worst either, and considering what was going on, i was very happy that she was down in once piece.

Post filght analysis indicated the following:

Nil damage
She needs more power during takeoff
Seeing as she can almost "prop-hang", she's not short of power in flight,
Reduce elevator throw,
Increase aileron throw
change R/X aerial to a whip type the jet boys use,
change to bigger main wheels to help get off the grass
start saving for a hacker A50 eturbine motor

A mate got some video of her in flight but you see very little, he was distracted watching the rollercoaster ride. i'll have a look again as see if it's worth posting.

Thanks

Dave

Glad she flew! Ive never used one of them big whips in my turbine jets, no need for it. Im not sure what Im going to do with my f16 yet...

Looks good!
