Intro + lunchbox, beetle, TT02b, terrescorcher, Kyosho & Quads - builds and issues

Recommended Posts

just because its bendy doesn't mean its not strong...... look at the wing of an A380 - the tip can deflect up to 7meters

they aren't worth the money though

Just considering LiPo options and what ESC combo to get (the tamiya ESC won't deal with LiPo so that can go in the beetle with a slightly higher turn motor and just use the NiMh

thoughts on these...

I just received 3 of this same brands 3S sticks today for my neighbor - I had two on my charger at 6A and after about 100 minutes I turned the charger off as they weren't balancing. I'll put them back on tomorrow and see if they balance. The 3S don't have a hard case so will need protection.

My neighbor had a 2S from them before but it was hard cased - it puffed but that was his own fault for charging it without a balance lead!

I'd look for the hard case version if the battery is exposed at all (as it is on a Lunch Box).

You should compare prices to Ebay Germany - I paid 18 pounds for each stick delivered (I made an offer) so 2S should be a little less.

I recetly fitted a TSKY 120A ESC to my neighbors car for him and it seems to work well - the 3S may prove too much for it though, we shall see.

Another 230 minutes and two are still not balanced. I have three packs:

Pack 1: 3.98V 4.20V 4.21V

Pack 2: 4.22V 4.16V 4.08V

Pack 3 managed to balance, each cell is 4.20V.

Make of this information what you will - maybe they will even out over a couple of cycles.

Cool, nice one. How are you finding the gearboxes holding up - still get clicking?

heh. I put the DF02 gears (or whichever ones fit) in mine, and it still clacks a bit. I need to trim down one of the gears though to see if fitting that helps.

Huge amounts of torque steer too, did you firm up the diffs any?

How much??

JJ

I paid £26 a pair from Ebay, shipped from Australia. Looking today same vendor has them for £27 a pair. Long ship time though. If the Hobbywing uk site ever comes back, check there.

need to add Quadcopter to the title as because of theibault's drone flying vids on here i've had to buy one....

Walkera Rodeo F150 150 Racer Drone set up for FPV flight (when i get the confidence)

Second hand this was pretty cheap with controller, 4 x LiPo and loads of spares for under £150

well my trip into quad flying hasn't gone well TBH

having learnt the basics up and down the drive i took a trip out to the local fields to practice banked turns etc

...only then did i realise i had range issues and "failsafe" was set to hold so the quad climbed and climbed and climbed!! Tx turned off as last resort and down she came...........

all "skids" destroyed and some broken chassis areas. actually i'm really impressed how well it withstood the crash

 

so new Rx board added (no change) so have had to order a new 2.4ghz Tx

also fixed some bits as spares are mega cheap...
