What would you do?
 

I have a brushless 8ight buggy I just bought has a 1515 2.5 on it.. and I also have 8ight-t that I was going to put the 1515 in.. my plan was to sell the buggy and its electronics in the 8ight-t but I just bought a 1521 should I keep the buggy how it is and put the 1521 in the 8ight-t or trade for a muggy and put the 1521 in it and put the 1515 in the 8ight-t.. what do you guys think?

Let's see. You have an 8ight buggy with the 1515 already done. You also have an 8ight-t with a 1521 motor. Sounds like you already have two nice vehicles with nice motors in them. (Although the motors are a little bigger than I'd go for those vehicles - I guess it depends on what you plan on doing with them.)

Is there something specific you like about the Muggy that sets it above the 8ight-t? Most of the time, you take a loss selling R/C stuff.

well i have bought this stuff off of fellow members.. the truggy isn't together but i bought the buggy together.. the 1521 will be here today.. even the buggy is new i am not upside down it since i bought it as used... i thought the muggy would be fun to bash and the truggy to play with at the track and around the streets..

My problem is that i am so indecisive that when i go to Denny's i have to closed my eyes and point at a picture to pick what i want...

lol, that's bad (about the Denny's thing). :lol:

It's hard to say what you would be better with. All three are good vehicles. So, it sounds like you really have no use for the buggy? Sounds like your decision is made to me...

I think I am going to sell the buggy I have a local guy that wants it..

I normally make my girlfriend decide where ever we go then I take hers.. normally when I am at Denny's its because it is 2am and I am wearing sunglasses and pretending to sing Georgia like Ray Charles.. I promise there was alcohol involved and a taxi.. I only say because it is true.. lol

So then did the waiters start singing "hit the road Jack"? :lol:

Anyway, I would go with the muggy and ditch the buggy based on what you have said. bdebde swears by his!

You will love the power your vehicles will have. Too much power is always good.......for me :lol:. You have 2 great vehicles with 2 great motors. You will have a blast with them.

Yep, Muggy is a real fun basher. A 1515 powers it just fine, but If the 1521 had been in stock at the time I bought the 1515, well, I would have got that instead.

The waiters loved me literally.. I think, I was there physically just not mentally.. I am hoping to make a trade for the muggy, I should know by today..

why does everyone on here have to live so far away.. except for bdebde I saw your van this morning down by the river...

Well, since you don't have your location listed under your avatar, how is anyone supposed to know if they are "so far" away?

Gosh.. I fixed it.. I'm from the spud state.. Idaho.. No u-da-ho hahaha

Pshaw, ID is not far from IA at all, only about 4 inches... :lol:

this is true but every guy has there own definition of 4 inches.. lol

can you tell I am bored at work..

...which is why girls are so bad at math. :wink:

I think you need a 1509/1.5Y, so you can pretend your 1515 and 1521 had a love child. :lol:

:rofl::rofl::rofl::rofl:.

I know I want it.. they need a love child.. You should just give it to me because no child should be left behind!

^^^^^

Well since you guys have helped me solve my previous problem I should probably move to my next problem.. before I buy a 1509 1.5 for the CRT.5 I need a power supply for the my spanky new charger that should be on my doorstep tomorrow.. I bought the Hyperion Duo so what power supply do I need. I have been searching but jsut haven't found the one I am looking for..

BTW I am still bored.. and my meeting isn't for like another 4 hours.. Oh yea, who schedules a meeting at 4pm...

a boss who doesnt want his employees going home early beacuse they are bored.........:sarcastic:

See how docile it is...just sitting there for the pictures? Ain't it cute? :lol:

I don't think so cause he is gone for the rest of the week after this.. I don't think he expected me to have my audit work papers done so he delayed it as long as possible...

The duo is rated for 180w/channel, which is 360w total. Assuming a charger efficiency of around 85%, you'd need a 12v supply capable of 35A. At 14.4v, you'd need a 30A supply. Yikes, that's not gonna be cheap if you plan on ever using it to its full capacity...

I think that is why I haven't found what I was looking for..

I found these PSs after I bought my Ofna 18amp....I prpbubly would have bought one of these

I have an Astron RS-70M I'd be willing to sell. 57A continuous, 70A peak, linear supply

You can find some specs on it on this page:

50lbs.. I would probably blow the breaker box if I plugged that thing in...

Nah, it's just a linear supply, so it's got heavier internals than a switching supply because it's a bit less efficient. A lot of Ham radio guys use these kind of supplies because they don't have any switching noise.

The PS units at Tanicpacks look really nice. A bit pricey but nice.

Astron makes a nice PS. I use the 25A model for my bench. Tweaked to 14.8v, the charger doesn't need to draw quite as much current, so it runs perfectly.

I think it's time for me to take out those huge power transformers I have laying around and seeing what I can do to make a linear regulator...

A family member owns a motorola communication bussiness, I wonder if they would have anything that would work..

Wouldn't hurt to find out...

If I bought one from tanic it looks like the APC - 30 would be big enough, it is 400w If i am looking at it right..

If you want to use the full output power capability of the duo charger, I'd step up to the next level. 30A @ 12v is 360w on the button. Don't forget, the charger will use up ~15% of that from inefficiency, so you'd be left with only 306w for the batteries. Either way, you'd be pushing it at its max, and it's always better to allow for a little headroom. I'd go with the 45A model (540w). Even accounting for 85% charger efficiency, you'll still have about 15% headroom when the charger is at full tilt.

For the price of the charger and power supply combined, you could just get a CC/CV power supply instead, and charge any lipo directly off it. Just set the max current (1C) and the max voltage (4.2v/cell X # of cells). Of course, this method does not have the added safety features of a real charger by detecting the proper settings based on the pack connected, so be careful. However just shy of 12s @ 20A is pretty darn nice. https://www.tanicpacks.com/product_i...74f16af042a459

I didn't read it that way... I am glad people like you are around that the geniuses while I am the nooob...

If the 30A model is 400w, then the actual output voltage must be 13.33v. Even so, the duo is gonna pull over 420w at full capability, which is pushing the 30A PS beyond its rating.

Of course, this all assumes worst case current draw. Are you going to be charging large capacity packs at high currents? Also, the most power drawn will be during the CC stage, right where the cells hit 4.2v/cell. This is not a whole lot of time. I tend to be conservative in rating everything; things just last longer that way. Could you get away with the 30A model? Probably.

Sooooo I got my used MMM (looks awesome) and the 1521 is freaking long... I think I am getting a cough at work... my only problem is rode my bicycle today and my GF borrowed the truck so I dont have keys to get into my house.. BAH!
