1/5th scale speed project??? - RC-Monster Forums

jzemaxx · **1/5th scale speed project??? -** 05.02.2008, 06:51 PM

Has anyone done a brushless speed car that is a true 1/5th scale. I haven't seen or heard of any records of a 1/5th scale car. I don't even really know what car would be good to use for something like this. I would imagine you would need a BIG single motor setup to reach 100 or if not a twin big motor setup. The 1/5th scale cars I have seen are usually 25-30lbs or more.

Been looking around and MCD and FG make some touring cars I believe. Does anyone know what they weigh?? I looked on several sites and haven't seen the specs of the cars. I am wondering what motor I need to be looking at.

I know modelsport.co.uk sell a few of the FG Marder 1/5th scale stuff- might have some specs and links on their site. As for which motor... Im thinking Plettenberg Bolido....

I'm trying to give this guy some advice: http://www.rcgroups.com/forums/showthread.php?t=854389

I will contact the company that makes a 4WD 1/5 scale and ask them if they'll be able to send the car or not. suicideneil already seen pictures of my 1/8 scale chassis and I'll be doing the same for the 5th scale.

I was looking at a 4wd touring car. I want something low to the ground and low drag. 100mph with a 1/5th scale is going to take some SERIOUS power. How does the Bolido stack up against a Neu 22XX series. I haven't talked to Steve in depth about the 22XX series yet, but I think they are rated 10K watts or more.

A german guy went 95mph with a Lehner 2240. He was using a Schulze 40.160 and seems to be 8S4P Kokam 3200. The Bolido is good, but Plettenberg only recommends up to 10S lipos. When I do build my electric I'll be using a Ney 2215/2Y for 12S and a 2215/3Y for 20S. I will use one of my Spin 200 for 12S and the SHV for 20S. I think 100mph should be very easy to do with a 5th scale.

I havent read anything about battery powered speed records in the 1/5 you should be him, but a few months ago cruising the net I saw the HARM electric LINK and although its slow and has a small engine I was thinking about that Pletty Bolido and one of my 1/5 bergonzoni gas cars I smashed up pretty nicely. With the engine off it weighed 12lbs and had a some more to shed. Only issue looks like getting the motor close enough to the spur bigger pinion I dunno,never got around to it, almost all of them that ive seen have the rear end set up the same. Those FG competition cars on that site look light, more carbon less aluminum Some pics

Bolido specs: http://www.plettenberg-motoren.com/U...lido/motor.htm

Its rated at 5kw, and 820kv, for 6-8s lipo. Not quite as impressive as I had always thought, and for the price I think the Neus would be a better choice- more kv ratings etc to play with.

On the car front, there are several companies in the UK actually that sell 1/5th or 1/7th TCs- i have some old magazines with pictures and infos- i'll see if i can dig out any useful info for you tomorrow- need to go bed now

as for the motor weight

jzemaxx · 05.02.2008, 10:28 PM

Is that your car?? Are you going brushless on it?

jzemaxx · 05.02.2008, 10:30 PM

I thought the Bolido was suppose to be a monster. The 2215's from Neu are rated 10Kw....so twice the power I guess. I will do that or go twin 1521's or 27's. I have extra motors so that is possible, but I get back into the issue of weight then. 2 of everything....

jayjay283 · 05.02.2008, 10:33 PM

those are 2 different ones in the pics both bergonzoni .. i was thinking about a bolido but got playing with my emaxx too much and dont really have anywhere to run a 1/5 it if i did, not that I ever ran them much.

I never found the bolido specs and didnt know if it was fast or a torque machine cuz I cant speak german lol
