I use optifuel in my 600 le

I've always used Model Technics 15% coptamix. My engines have NEVER missed a beat and always have enough power. I did try Byron fuel 20% once but i found my filling hose got clogged up meaning I had to blow the hose clean which is not a pleasant experience.

Model technics 16%, used in all my nitro engines, both heli and fixed wing
no problems after years of use

i use opti in my trex 600 nsp os 50 engine and i love it .just wish the colour was a bit more visible when the heli is in the air

The reason behind the 2 fuels are because I can pick these up local. I bought some cool power just to try, I don't see any deff from that or opti.

None of the above I use wildcat 30% 3DLV

[Mslater]

Optifuel 20 SLV

Bit of an odd question really.

What type of car do you drive? BMW or Mercedes? Well, errr, actually neither, I drive a Ford.

What's the real question you're looking for an answer to?

Model Technics 20% Coptamix for me - goes in all my helis and all my planes, all of which are 4 strokes up to 25cc and include a YS 4 stroke as well. The stuff just works, trouble free.

Not sure how that really helps answer your question though.

You can get a clearer fuel tank for the 600 mate. The standard one is quite cloudy. I changed mine when I crashed my 600 and a blade burst the tank and it's now easier to keep my eye the fuel level.
