I think the right size is a 5.4 gram?



By the way........is that a good price?

When fitting equipment into a TTT, I always measure the size of the case (or remove the case when possible) and dont pay much attention to the actual weight. 5.4 gram? I dunno....

Yea, that Tower price is $5 or $6 bucks less than I usually see them for.

:ö: squeegee,

The 5.4gram is the exact weight of the servo, which is important if you are building an rc plane, wherein weight is one of the factor to consider if you want your model plane to fly properly, but if you are building a 1/87 rc truck, weight is just an option and size does really matters the most, next to consider is the torque or the mechanical output of a servo, but speaking of torque, micro servo such as the 5.4grams servo has more than enough torque to turn even a 15mm or bigger diameter off-road tire ;).

In the description it says it should not be used on models which require a lot of torque. This doesn't apply to TTTT like you said does it?


Thank you guys for answering all my questions.

:ö: the steering of a 1/87 truck i guess does not requier that much of a torque to smoke such servo.

I guess that has to be true........to turn a rudder or to turn some "micro" tires. A TTT isn't really heavy enough to need a lot of torque to turn its wheels.

:ö: you got it!;) -æ

cool!
 

cool news! just got back in town tonight...i'll chat with you as soon as your available on the subject.

re: 1:87 and weight....the added weight of using brass stock and all the electronics make it more stable (in my opinion/experience). if you can try to keep most of the weight as flat as possible...it will help lessen the tendency to roll over on an obstacle course.

using solid brass like overlander and killer seems like it would give it a steady platform which has enough weight to keep it planted for traction. in real life...the trucks are enormous and do weight alot...

I know this is EXTREMELY off of this forum's topic but............ have you ever considered building some R/C planes? I know your work on planes would be amazing. I have a Firebird, a Firebird XL, and a five foot wingspan electric trainer.........I also have put 723 hours into my Real Flight simulator.


I am working on a line of micro planes from cheap R/C tanks and rubberband powered planes. They have reeeaaaallllyyyyy simple steering.........just like a tank........no need for a rudder.

off topic
 

:ö: when i was in grade school (, i was very much interested in Aviation, my best creation (with y Father's help) that time was 12Volts 130 type dual motor 12 inches long helicopter, the thing just flew up and down or simply hover on top of a table, where it is connected to a multi channel (1.5v -12v) 12Amp power supply via wire sticking out of its fuselage.

well, with some 1:28 overland work out of the way...i look forward to jumping back into some tttt!

Wow....really nice work on the Overalnds. If I had enough money I would buy one...maybe in the future.

Now that you are getting back into some TTTT action.......do you have any plans on what you want to build next? Optimus Prime?

What's this about larger trucks?
I have been away from the forum for a while and have just discovered what has been going on, Arch2b glad you are putting your efforts back into 1:87 after all isn't that what TTTT is about? (or as close as you can get).
By the way I quite like the other trucks and they must be much easier to work on and find parts when you drop them. I spent half an hour this afternoon trying to find a nut I dropped - I gave up!
Still working on my TTTT, the slight delay is hopefully over;)

Yes..
Small parts always have a way of bouncing in the most unreasonable places.

If you drop a small part on shag (baby) carpet, put a sock over your shop vac nozzle and use it like a filter. Empty it in your hand as you turn off the shop vac.

(shag, sock, nozzle....you know what I mean)

My TTTT projects are on hold for the summer. One reason is that it has been over 105 degrees F for about a month. That makes the temp in my shop go up to about 120+ F.

Try finding a dropped part with sweat in your eyes as your kneeling in a pool of sweat. Only to find that the part has stuck to the sweat on the back of your hand all along....:p

Besides, it's boating season....:cool:

Just to let yall know, there's another TTTT coming, from me! This is my first job working with brass/soldering it together, or anything like that (brazing, welding). Its fun, I've made the frame so far, but am having a terrible time with the drivetrain :( I just can't seem to find any worm gears that fit my motor output shaft. Well, I actually did find a suitable one, but the hole for it is too big for the motor shaft, I need to enlarge the shaft so the worm gear fits snuggly on it. Any ideas on this? I also I need to do this for the gear on the axle (its only 2wd, its my first truck!). But its really bothering me, and I don't want to buy any premade parts. Any help is appreciated! Thanks.
