  1. i would go 20% , i am not sure if its still available but i found tornado fuel was the best available when i ran nitro cars ( and i tried every fuel i could get my hands on) , it starts faster and keeps the engine measurably cooler and internally cleaner (less varnish build up) than any other fuel , it was also the fuel of choice for the world champion 1/8 circuit for 3 years in a row ,

    :)

  2. yip, block sand it back , a matchbox makes a nice small block and keep it gentle , taking extra care to not sand in ridges (the block helps keep preasure even and well spread) then wet sand with very fine wet or dry , finish with 1200 and 1500 , if you get back to the plastic stop sanding that part , all you want to achieve is to flatten the runs back to the same level as the surrounding paint .

    for future reference , get a jug with some hot-ish water and stand the paint in it for 5 minutes , shake for 2-3 minutes then back in water for a minute or two then a quick shake of 30 seconds and spray , dont hold the can too close , around 20+cm from surface to be sprayed , allow time for each 'light' coat to dry , around 5 minutes in a warm room , 20 minutes in a cool room , use long sweeping strokes that extend beyond the work ,

    my best tip for painting is tea and cake ! , really ,, get some nice cakes and sit and have a cake and a cuppa between coats .

    you have to be portly to drive a big rig , right? :D

    take your time and you will get sorted ;)

  3. sensored systems have very smooth low speed performance and also monitor motor temps at the esc and will go into safe mode if the motor temp exceeds threshold ,as percymon mentioned , unsensored set ups can stutter at low speeds , known as cogging , sensored systems are IMO better but not essential , sensored motors can be used unsensored and most sensored esc's default to unsensored mode if there is a failure of any of the sensor harness or sensor's so you can keep racing ,

    for good acceleration simply choose a motor with adjustable timing and wind the timing into the negative range , turn up the punch setting on the esc and order lots of tyres :lol:

  4. i am using these among others , http://www.hobbyking.com/hobbyking/store/__45914__Turnigy_TrackStar_10_5T_Sensored_Brushless_Motor_3730KV_UK_Warehouse_.html , i have it in 17.5 , 13.5 , 10.5 and 7.5 , the 10.5 should be quick enough , keep in mind you can gear up a brushless system a bit more than you can a brushed system , if you go for an esc with boost and turbo they become quite scary , use in open spaces ! , with the 7.5 i actually ripped a brand new set of tamiya type A slicks from the rear wheels , i dont mean the glue gave up , the tyres literally ripped from the rims :)

  5. i havent used the turnigy esc you linked to but it looks good , the 4 pole motor is aimed more at short course and is rather power hungry , aim for around 3500kv for the motor and keep in mind that you will have to solder on a battery connector with esc's from HK ,

    i use these https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=64595 , and their 120a brothers , i have 4x 60a and one 120a and they have all been flawless , they are not waterproof sadly but , they can take a 13.5 motor and boost them up to 10.5 motor speeds ( i have run 8.5 on them but it was all too fast!!, they have good caps fitted that allows them to run even well hammered batteries , my old yeah racing 3200 li-po packs only manage 2200mah now and only give about 7.2 v for most of their discharge and the esc never stutters with a 10.5 and the boost and turbo turned up which equates to a rather quick system , plus you can grab one of these https://www.hobbyking.com/hobbyking/store/__56469__USB_Programming_Adapter_for_Hobbyking_X_Car_120A_60A_ESC_UK_Warehouse_.html , and tweak it to very slow and soft all the way to tyre removing grunt with your pc,

    take your time and have a blast

    :)

  6. Been looking at a brushless combo on HK. It's the lipos and charger that are the massive expense. Could I still use the Nimh in brushless? Along with using Lipo?

    yes no problem , just set the low volt cut off to 2.7v per cell and you will be good to go , especially once your packs have been cycled through a few times , i wouldnt go much lower than a 10.5t though , just to save over working the nimh packs ,

    have fun :)

  7. He did it to me a while back mate when he sold me his Stug 3 (sorry Nic, couldn't resist)

    That reminds me, can the Stug be converted to BB from infra red as I fancy shooting some stuff?

    :lol:

    from what i have seen when looking at the masses of options you just get a new bb gun and swap em over ,

  8. ****! you aint having any good luck at all ,,i think its time you wrote to santa and asked for a brushless system with li-po and a new charger !

    edit:

    i didnt know that **** was considered a bad word , its in the English dictionary and is a perfectly reasonable and inoffensive word but hey, i am sorry i used the word **** and **** it i wont use it ever again on these boards , :)

  9. Right, I've just put them both on, one at a time of course, lol. Give them both full throttle straight off and same issues, the 3300 did work at full throttle for about 1/2 a second. Retested both batts, holding at around 8.2 - 8.3 volts

    hiya man,

    this is odd , even low quality batteries in decent condition should be able to run that motor ,if it was a 5 turn single then i would expect the batteries to struggle , i cant find any info on the mtroniks 11x2 , i am wondering if the brushes or com are damaged/worn and the motor is trying to pull too much current , effectively going short circuit across the winding's , as i mentioned earlier voltage would need to drop very low for the esc to cut due to bad batteries so now i suspect the esc/ motor to be at fault , do you have another motor to try ?

    edit:

    even try the motor with the pinion removed to see if revs ok with no load .

  10. Looks pretty good to me. The metal tracks give it a good scale weight and make it behave a lot more like a real tank. These HL are suppose to be able to handle 7.4v lipos but you'll need a low voltage buzzer as the ESC arnt set for them.

    was thinking the same , i have a couple of spare alarms kicking around , it would have been awesome if there was a spare couple servo port's on the control unit to run proper esc's but for the price i will be happy with the two speed .

    have you tried fitting a better speaker at all ?

  11. Oh eck! :D what have I started now!

    What one did you go for Alfa? I've got a metal upgraded Tiger 1 that I'm in the process of configuring into a mid-late war tank, the sort of thing that would've seen in Normandy during the invasion.

    A friendly helpful tank forum is below:

    yip , its all your fault sir :) ,

    i think its the early tiger but a few of the details are from the later tigers , air cleaners for instance , http://www.ebay.co.uk/itm/321010303762?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT , latest rx18 board , smoke , sound ,bb gun and a few metal upgrades , looks like a bargain , cant wait to terrorize the neighbours cat :ph34r:;)
