Hi,

I run a Raptor with an OS32, just getting back into using it. I used to run Coolpower 15% as that is what was recommmend when I first bought the heli, but its expensive to get shipped as cant get locally.

Looking at changing to Bekra as I can get it locally (not much choice around here), anyone tried it? I found a thread from 5 years ago but not sure if its still the same.

Also what % should I run for general hovering (and crashing :-( ), not into 3d yet. Do I really need 15% or would I likley not notice any difference with 10%? Do I need to retune if I switch?

Thanks,

Ants

I guess AgentOrange has been effected by his name and couldn't understand the question.

If the wings are traveling faster than the fuselage, it's probably a helicopter.

I run 10% or 15% Bekra (depending on availability) in all of my models. That's OS 32, 46, 51 and 91. The tuning difference is minimal, especially for general sport flying.

Having switched from Coolpower a few years ago, I personally think that Bekra is the better fuel. It seems to run smoother than Coolpower and seems to be more consistent from one gallon to the next.

I use it in conjunction with Enya no3 plugs.

Thanks, I am going thru Newton Abbott tomm so will go into the Bekra RC shop and get some Bekra 10%. I normally run OS No 8 plugs, so will have a chat with them and see what they say.
