whats wrong with hobby king

here's the 12v power supply that i use : http://www.amainhobbies.com/product_...er-Supply-Blue

I was looking at these.

I know they are Venom and I hate Venom's Nimh but the lipos they make have never given me any problems. The MSRP is much higher then the LHS price, at least by me it is.

I was looking at these for there multi function plugs. They come with 4 different style's of plugs to choose from. Example: If you have TRX charge leads off your charger, you use the TRX plug on the pack to charge it. Then you use the Deans to run the heater. It's a nice feature IMO. So, you have Deans, TRX, Tamiya, and bullet plugs that come with them in the bag.

Excellent power supply...

I got this 12v unit 2 months ago, and now the heating element rubber coating is cracking. It started off splitting in that area and now its drying out and coming off. I have been using a 12v volt gel cell and the 12v mini power supply that’s suggested on this thread. The unit is still fully functional as it heats my engine to 200F in just under 10 minutes, any ideas?

I don't remember anybody recommending a 12v lead acid (gel cell) battery ?


That's interesting forsure

any factory cutouts on your cooling head with sharp edges in the area of damage ? dremil them smoother (must check mine while i'm thinking of it )
what voltage have u set on the output of the power supply ? needs to be 11.1 - 11.5v
what voltage are u charging the gel cell to ? needs to be 12-12.5v max to extend the life of the heater not 13.8v as some are saying
i've used mine daily at these settings for 3 months without any issues what so ever

I do believe the 12V gel cell is ok to use. What kind of engine is it? Maybe the cooling head is milled in that area and snagged it?

I would just email Comp Heat. They have great customer service.

Nothing is wrong with Hobby King. I have several of the Turnigy lipos and love'em. The problem is, I am stationed in Japan and they don't ship to APO. Even I have someone else send them to me, it will take a little over a month to get them.

Thanks for the option. I have a Kyosho power supply that will vary the voltage from 12 - 15v. I was wondering if anyone has tried which I now know someone has. But some places I go to does not have power. So I am still looking for a decent cheap 3S. Thanks though.

with the head temps around 200*.
i was getting 125* at the case, and mounts.
and 100* on the bottom of the chassis at the mount bolts. between the bolts, maybe 90*.
70* on the chassis up by the front diff.

the bottom of the chassis was warm to touch, but defenetly not hot. makes me wonder after a good run, or practice how warm the bottom of the chassis is after a couple tanks of fuel.

if it's starting to push into the chassis all is good,
another 5-10 minutes would see the chassis temp up to about 150 then u know all the internals are up to temp, crank, bearings, rod ......
it all helps with the life of your motor & wear n tear on your buggy/truggy just in wasted warm up laps, i fire up with 30 sec to go to the start of the qualy or finals & only got caught out once with a plug that i forgot to change the week before !

love the product! 12v heater does a pretty good job heating things up!

Cool set-up Matthijs, I like to mount my Monitor's on the bottom of the box, Or in your case Right on the packs so I can see them through the crack.
