How much weighs your truggy brushless ?

[jollyjumper]

pierre, no need for 5s lipo, just run 2 trakpowers for 4s and keep the bk speedo and 8xl. it will be plenty to handle. it will then have 1400 CONTINU watts avaible. even loads more peak horse power.

[squeeforever]

The 9920 is actually rated for 6S LiPo, but I fried a 9920 and 7020 on 6S, so I would'nt really recommend it. The 8XL on 5S would be nice combo.

ok thanks
do you have a video about 8XL with 4S and 5S ?
please

Pierre,

As I stated before, my Muggy is a good 13lbs. (5.9kg), with an 8000mAh 5S battery packs. I've never had a truck before, and am surprised that mine is so much heavier than other true truggies. Anyway, I run an 8XL on 5S and it is almost too much power. Any sudden application of throttle results in a wheelie. I'm going to go to a 9XL for 5S, which should be the same performance as a 7XL on 4S, but will run cooler (less current draw) and have more runtime.

I think I'm going to find myself a real truggy and get rid of the Muggy. I don't like the fact that my truck is two pounds heavier than any other truggy without any advantages.

get a 8ight-T.

Nah, I'm thinking either MBX5T or X-Ray.

My 8t weighs a little under 9.5 pounds RTR with a 5k maxamps 4s Lipo packs. I just finished it up 2am Sunday morniong for a day of racing(had fun, but learned a few lessons as well). :)

The good news is that I put a good testing on a 16 tooth hardened pinion(used 8's stock spur) and the truck and conversion held up fantastic. I lost my pinion set screw in the main, though(the metal pinion on a metal spur has a bit more vibration than plastic/etal and I hadn't loctited the set screw). The pinion looks perfectly fine after a day of racing, too (besides the normal wear of the black oxide coating). I plan to offer 14t, 16t and 20t hardened pinions in the store in a week or so(once I get the gears cut and sent to heat treat for hardening and oxide). I will add more depth to the hardened gear line as well, but the 14, 16 1nd 20 will be the start point.

I will bust out a few of the 8t kits this week - here are a few pictures of my truck(kit will allow mechanical brakes, though I didn't have the needed motor or pinion/spur combination to allow use - I also have not yet figured out the brake actuation) - I used a bit of drag brake on the MM controller to get the diff working a second or so before entering the corners and it worked out great). The mount, top plate and front spacer will accept up to a 51 tooth spur gear without modifying the chassis. My test unit had a Castle MMaxx controller, UBEC, Novak fan, Wanderer/Feigao 9xl motor and a new black RC-Monster heatsink. I used a 16t hardened pinion on the stock 48t Losi spur. :)

Here are a couple pictures :) :

By the way - the included mud guards on the Losi are terrific - these pictures were taken AFTER the day of racing (as evidenced by the packed dirt on the rear suspension arms) - I havn't even blown off the truck with compressed air yet! The inside stays nice and clean!
The chassis does have quite a bit of flex, too. I will probably make a custom rear brace to minimize this, though it didn't have any detrimental effects on handling, I would like to lessen it a bit(the nitro motor mount braces the chassis a bit, but this is obviously removed for the conversion). :)

Hello
very good 8T
I am interested for a 16T for my hellfire
I look for motor Clamp mounts like that :

do you have ?

would this help out some?

[Pierre]

do you have this kind of motor Clamp mounts ?

good to see you were able to make it to the race. also good to see that you dont have to modify the stock chassis. do you have a picture with out the battery in the truck? just want to see the battery tray a little better.

anyways, I will be ordering this as soon as you get some of those kits made. :) actually 2 so I can change the one in my buggy while I am at it.

[jollyjumper]

wow, good news.
glad we may be able to run steel on steel anyway.
maybe the problem was a not-solid motormount of the people that saw pinions fail after 2~5 packs.

Hardened pinions that work with the steel spur gears are good news. They would surely make my life easier.

What kind of run time were you getting Mike? Was that 5000 able to handle a 30 minute race? I know you said you didn't finish the main due to a pinion screw, but have you tested the run time before that?
