I went out yesterday with the headspeed bumped up to 1930
thats 12391 engine rpm.
I always like to give the governor some error room to overspeed,
I also took off the stock 95mm plastic tail blades and put on 105mm rotortech tail blades..
I had to drop the gyro gain a lot it holds like it's supposed to now
it works great.
even at that headspeed the fuel in the tank is not foaming but the vertical fin has a slight blur to it i mean very slight less than a stock 231 would.
im running 710's as you all know and the machine is an absolute animal!
i mean it's evil, very fast cyclic response and a ton of power
im hoping to get my friend Rick to smack it down so I can video it for all of you to see
It's as good if not better than the teaser video's that Century has on their website. It's darn close to nitro power.
She likes fuel at that headspeed
so far the engine is running like a top,
If your interested to know my set up is,
Century Radikal 30se
Wally Z30 Hyper / Century slim torpedo ( no insert or end restrictor)
Hitec 7940TH HV servos I love these servos
GY601w the servo it came with.. ( the tag fell off long ago)
Rotortech Scott grey 710 mains 105mm tails and paddles
felt in tank clunk
head button ( completes the look of the head)
pull start adaptor (with EZ-Pull starter)
Century air cleaner
GV-1 Gov using stock pickup and magnet on rotor of motor
LiFe 3200mah rx Pack
(I like the LiFe due to safer chemistry in close proximity with gasoline)
Please if you decide to go with this engine,
be sure to follow the break in instructions 100%
my low needle is 1/16 th richer than stock my high needle is 1/8 richer than stock.
yours may differ due to atmospheric conditions and humidity.
be sure to dial indicate the fan hub to get it less than 0.0005 runout
sometimes all it takes is to pop it off and re install it and check it again,
i pulled mine off like 8 times before i got it down to 0.0003
and be sure not to stack both brass washers on the clutch itself only use one and crank down on it to seat it properly.
im still running 5oz synthetic oil to a gallon of 93 octane fuel
stock engines can run no problem at 87 octane but the compression has been altered in this engine and low octane fuel ( may ) cause detonation wich will cause bad viberations and the top of the piston to appear sandblasted ( the 93 oct works great for me thats why I use it )
Be on the look out for a video hopefully by wednsday i can put one up.
