For the past few days i've been thinking about putting a 550/600 sized motor and esc into a 500 frame. I'm pondering the power to weight, head speeds, and flight times with the bigger, more powerful, yet lower kv setup. The max battery size i want to use is 3300mah 30c. I can fly these packs in my 600 for 3 min, so i should be able to get 4+ mins of stick banging in the 500, right?

Do you guys know of this being done? Or am i just asking for trouble?

That's an interesting concept. I don't see why it would not work. Was just a few years ago ppl thought a 450 on 6s was a silly idea. Sounds plausible to me anyways..

Regards the Red Brick 80amp, Hobbyking support emailed me a programming sheet if any of you want it for your records-

Link- http://www.hobbyking.com/hobbyking/s...2X53414X49.pdf

I think my issue is a throttle range issue, but I have not had a chance to investigate it any further yet. If I cant get to a happy place I guess I'll just source another ESC.

Mick

ps- Thx to those who responded

Got my new slider from Hobbycool. It was in great shape. I had to replace one screw that was out of round, but all the bearings were good. You do have to take it apart and use a toothpick to apply loctite to all the screws like all new parts. There is also hidden cost. You will have to buy a new pitch fork assembly, but you have to on the align as well. Total cost $33 VS $60 that is the unit and fork for either.

Not much happening lately. I did put the Tarot tail assembly on the 6S 450SE with some HK tail blades. It has some power, I'll tell you what. I think it goes about 110-120MPH I also got a few 1300mah 6S that are about the same shape as a 3S 2200mah. http://www.hobbyking.com/hobbyking/s...dProduct=23919

On the HK500GT, I had a tail link ball back out (maybe vibration or poor thread lock) and had a minor crash. I replaced a few parts (main shaft, feathering shaft, blades), but it was obvious the frame was bent at the top so I got a CF main frame. Also installing an HB3650 1600kV motor and sticking with a 12T with TIG blades and white CF tail blades. Also will put black nylon sleeves on the servo and ESC wires

OT, I spent like 45 minutes dynamically balancing the tail on the 450 and ended up with an ugly piece of blenderm tape on the blade as usual. Any suggestions for a better looking (invisible) piece of tape?

Thanks, Dave

If you do that might as well stretch the boom 10CM and put 525mm blades on it. You can fit Gaui X5 grips on a standard Align width headblock if you also use the Gaui feathering shaft which allows you to use cheaper and more widely available .30 blades with a 12mm root rather that having to use expensive 10mm .30 size blades. You might have to add an extra shim in addition to the collar but the headblock width is virtually identical, if it's any different it's on the order of a mm or less. They both use 6mm feathering shafts so dampers will be no problem.

Infinity Hobby has the standard Align 500 Pro bellcrank and pitch slider on sale right now. The bellcrank is only a dollar more than the Tarot version.

yeah, but i dont want a 'bigger' heli, i want a more powerfull 500 size (which is really 450 size if the companies would agree on a size scale). I might use a standard size servo on the tail, but will keep it as 500 as possible to take advantage of the power to weight ratio.

You'd have lighter disk loading though and still have higher power to weight.

I'd like to just put a bigger motor on this heli myself sometime, even if it means the flight is 3.5 minutes, instead of 5. I haven't seen any motor only mods, only making a 500 into a 550. I just started thinking about it with the OPs post. I haven't looked into it obviously. I should look into that.

I was able to find one vid on youtube with some guys who put a 600 sized 'NEU' motor in a custom 500 frame that allowed standard cyclic servos. With a bigger pinnion they were able to get around 3000rpm head speed. It sounds pretty impressive.

Have you looked into random 600 size motors that are around 1600-1800kV? That's where I was going to start.

Say you have the http://www.hobbyking.com/hobbyking/s...dProduct=11186 is about the right kV, but too large in diameter. Will look around more. I think mhills said something about this some time ago.
