Bekra so far

[chris jones2.4]

think theres something wrong on yours somwhere alex

[Geek]

I do agree with that- my engine is a PITA first flight of the day, though I reckon that is just mine as Chris's seems fine.

That's a good sign.
Chris's engine might be a bit more knacked

[moonmanflyer]

Still myself using the Coptamix 30 myself, and at the weekend my 700 had so much power, it got very abused, and i even love the smell, nice and sweet.
All my engines, even the 50 hyper in my vision love the stuff

Those that find the engine gummed up on the first flight of the day will find the problem disappears if you switch over to Coptamix instead. It's the same price as Bekra (all bar a few pence) and is also Model Technics. The difference between them is Bekra has a blended oil mix and Coptamix has fully synthetic Klotz oil. You'll also get much less gummy residue all over the heli after you've been flying. If your local shop stocks Bekra, then they can get Coptamix as well.

My fuel of choice is Coptamix.

Said I'd post as I went along. Whipped the back plate off, approx 40 odd flights on 20% Rapicon. No rust yet

[Nick B]

Thats bloody amazing mate

[waveydavey]

It's that shiny Nick I couldn't dim the flash enough to stop it reflecting

I've been saying for nearly 18 months now I don't get rust with rapicon and my less than careful shutdown and care routine. In the garage, just make sure the pipe is blocked and the engine is on top with the throttle closed.

[MartinH]

Think I may have to go forth and use a bit of Rappy, hopefully the LHS will sell it.
Ive used a few tubs of Opty lately since switching from MT so will be good to see how Rappycon does

Get hold of Rob blake at EvoRc, he'll sort you out.

[MartinH]

Ive got perhaps 2-3 tanks of opty left so good time to buy a new fuel. Will do .


Just checked and its cheaper to, even cheaper than my LHS on 30% optifuel and they do do it cheap.

[squeaky pete]

rapicon is the way forward i had a ys91 that ive used all summer, changed the bearing in april, countless gallons thru it now, no sign of giving up yet

When done,whip backplate off and check for rust,my mate put 1 gallon through a YS91 after using Bekra for 2 years then his bearing went a week after the last tank
