After a few days of testing and tinkering i finaly reached over 100mph with my TC4, 107 to be precise. I used the Mamba Max 7700 motor setup along with two DesirePower 2S+2S 3700mAh 25C LiPo batteries.

This is what Magnus said about the run:

86 mph

And still on the 28/72 gearing, didn't have time to redo the motor mount for the 35T. I did a few changes to the chassi and mounted a cut down EP 1/10 buggy wing and now it was ALOT more driveable. So today i only crashed once lol.

Tomorrow i defently gonna have the 35T pinion in it and I will cut down the wing even more but with larger side damps. Will paint the body too if i get time aka. not feeling lazy

Short movie with the regular crash in the end

Fasterthanspeed's Big Block Serpent

Fasterthanspeed says:

Well I have participated in the event both years its been going on. I havent made any records yet but hope to soon. I havent had much time to work on it, but I have had a little bit of time to make a few parts for it.
Its based off a serpent impulse. With a rossi maranello in it. A futaba gyro in it. And plan on running some type of gtp body on it.

1/5 scale 26cc Zenoah on nitrous - 8.9hp!

A test engine on the dyno with nitrous..

Ian Oddie has been working on this spectacular engine for a 1/5 scale:

Even though i've been into racing Rc car racing quite seriously for many many years, i didn't know there were any organised top speed trials until Mr Lovering contacted me a few weeks ago and made me aware of it all!!

All very very interesting, but i don't see many 1/5th large scale cars attempting it??

I would have thought they're ideal, despite being bigger/heavier we use a 2 stroke petrol engines which are relatively strong and can be made to produce as much power as can be controlled with.....nitrous!.



A standard 23cc zenoah has about 4 bhp with good racing pipe fitted, a 26cc has around 4.3, again with a good tuned pipe fitted. Tuned they have around 5.9bhp and 6.7bhp respectively, but with nitrous the 26cc in the picture was tested up to 8.9 bhp and that limit was only set by the nitrous/fuel jets in the solenoids. The compression and ignition timing were all set-up with nitrous use in mind, plus the piston was tapered to prevent it nipping in the cylinder with the extra heat/pressure from the use of nitrous.

I'm sure with suitable gearing (2 or 3 speed box) and nitrous a 1/5th scale will be able to go very very quick.
