First hand experience w/ losi's electric conversion vs tekno (8ight is v1) -
06.26.2009, 11:03 PM
I've been running a tekno v3 8ight buggy conversion for some time now and I was going to do a rebuild on it and picked up a brand new 8ight race roller kit for 310.00 to do my swaps.. anyway after driving my brothers 8e 2.0 for a few minutes tonight I was wondering if I would be better off just getting the losi conversion kit and swapping over vs trying to keep my tekno kit. I'm just wondering if anyone has raced BOTH on the track and had a chance to compare and decide which is best.
I know the tekno has the mechanical brakes which is nice and I do use, but I'm fine working motor brakes as well (use to it from my erevo). Other than that I'm not sure there was anything holding me to the tekno kit, and it would be nice to run the plastic spur so I don't chew through 13 dollar pinions running the metal spurs.
Thoughts from any vets?
PS I'm not switching to the 8ight 2.0 this year.. maybe next.
I've never owned a Tekno kit nor have ever used mechanical brakes, but lighter is certainly better and I bet you can shed at least 4 oz of weight and gain more than a minute of runtime just by switching over to the motor brakes.
Check out my custom converted 8ight:
Sub 7lb, lowest CG of any 1/8 buggy

a 4oz servo and some linkage isn't going to change the handling... id be more apt to lean to the tekno as the battery tray sits a lot lower and makes for a lower COG which will impact the driving more than loosing a servo. The balance front to rear and side to side is really what I'd like to hear about from someone who has raced both types. As a matter of fact if you wanted to run motor brakes you just leave the linkage and extra servo off and use them w/ the tekno... it's not mandatory or anything ;) I'd also like to hear about the floating motor mount vs using tekno's awesome chassis mounted motor (lower cog and no chance of damage).
If you are infact going through pinions the chassis mounted motor is most likely the cause. Chassis flex alters the gear mesh, a diff mounted motor keeps a constant mesh.
I know still not the answer your looking for, I think your just looking for an excuse to spend more money though!
Tekno has much lower CG, its battery tray lays tightly on the chassis while the Losi tray is about 10mm higher above the upper surface of the chassis, making the battery look like living on the 2nd floor.
Tekno's motor mount secure the motor very firmly, totally worry free, while the same thing makes gear mesh adjustment a painful experience.
But this chassis mounted motor have issues of varying gear mesh during chassis flexes
Tekno use none standard long shank pinion that cannot be found anywhere else.
Losikit saves you some bucks by not wasting a cent in clutch.
Pinion change and mesh adjust is much easier in Losikit.
With Losikit you can run plastic spur for a quite ride.
With Tekno you must use 13T+ pinion to have secure pinion-spur contact. Actually I bought myself a 49T(1 tooth larger than stock) robinson spur to use 12T pinion for a proper gear ration when run 6S on 2200KV MMM combo.
You can't use Hacker or Feigao motors + pinion gear with Tekno for their shaft lengths.
Your motor bearings will take more stress and wear quicker with Tekno long shank pinions.
Tekno kits' CG shifts about 10~20mm to the rear end away from center.
Tekno kit takes packs no longer than 145mm, Losi runs 168mm pack with no issues.
Tekno has beautiful colored chassis compared to Losi 2.0's deadly dark metal sheet.
And you're faster with which? I have both, but I've only run the 8ight as a nitro, then went right to tekno.. it was time for a rebuild so I bought a kit (great deal) and now have a full Race Roller (version 1) that I could get the electric kit for and switch over and just sell my tekno setup...
Stum, I can't answer your question on which setup I would prefer as I don't have experience with the Losi conversion but I do agree with you on the quick wear of the long shank pinions.
One suggestion I have for you though, you should take your new Race Roller 1.0 and get the Tekno 2.0 buggy kit and the 2.0 rear drive shaft make yours a 8ight 1.5, that's what I did. The battery tray is even lower and you will notice additional steering as Tekno moved stuff a little more forward. Just a suggestion for you that a lot of us Tekno users are doing. You may have already considered this, if not you won't regret it.
