8S power and you are still going to use the ESC BEC? Brave man. Personally for anything above 4S I install a separate switching BEC or RX pack; I can't imagine the additional weight would be a major issue for this model. Alternatively you could stick with the ESC BEC but add an Optipower Ultraguard for additional peace of mind.

I think there is something wrong with that too - the first half of the list says it's an opto ESC, then the last four lines are specs for a switching BEC. I assume that is a completely separate unit?

Yes, well aware of that, hence why I questioned your original post on the last page where you stated you would use the onboard ESC BEC.

A word of warning on the cheap HV BECs... the Turnigy one that I was going to put in my Miss Wind failed during initial testing in the plane on a 6S pack despite running happily for 3hrs burn in on the bench on 3S. The learning for me was always test BECs for a good few hours using your intended input voltage before installation; if they are going to die, it's normally within the first few hours of operation.

Did it fly successfully, or were you beaten by the weather?

Hi all

Maidened the RIZLA xl last week flew very well but I felt it was a bit heavy with 10s lipos

coolCame in fast and needed flaps to slow it down !

So back to the board new motor Turnigy G110 295KV

8s lipo 65c. (2x4s) in series

18x10 carbon prop

Saving weight was over a 1 lb. and 400watts of extra power

Full stick power is 77.32 amps at 33.01 volts gave me 2159 watts

Maiden will be Sunday whatch this space for video if all goes well plan will follow shortly wink

Maiden to day on the new power and lipos

Excellent on all aspects slow speed and high speed landings were much better on the lighter AUW wink

Now onto the next RIZLA ultra wat do you all think

Video to be uploaded in the morning

Mean, sleek looking machines, Gary!

While we are waiting on the plan for the big 'un, where can I get the smaller plan you enlarged from? I've googled in vain sad
