Can I ask how much the Wally motors cost?

Need to budget my shopping list for my return to gas with the Whiplash Gasser.

For the love of the hobby

You can check RC-Aftermarket
on the front runryder page.

It looks like the whiplash is going to be an RC version engine though.

whoops..

Outback beat me to it

Could someone point me to a link or tell me what are the benifits and differences of the RC style motor compared to the PUH?
thanks

RC motor has much better cooling, and runs smoother.
Power is the same as far as I know, same as weight.

Thanks Gorn
I'm assuming smoother from the factory than say a stock puh 26?
Or smoother than a modified motor puh? Should a RC motor be modified too? Just wondering why it's smoother. Is it also the same weight as a puh with out the pull start removed?

smoother than a standard PUH.

RC motors have been modded by Hanson and Toxic already, so yes they should be modded...for power
I understand that the modded motors are smoother than stock, so I guess better than say a PUH 3d Max.

I havent owned an RC motor myself yet, just going off memory from differences I have seen posted between them.

The weight difference between eachs tock motor, both with pull starts is marginal, and not worth worrying about.
Im a gramme weeny myself, and Im not concerned at all about the minor difference in weight.
From memory it was maybe 50g.

Calling all builders this past Fall, no one had figured out how to mod the G290RC yet. Hanson was working on it and had a few out for test. I now see they have one available on the web site.

Hi all,
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.

Rob Landry.

In real Hot Humid weather with the higher compression as you state it would especially be a good idea I would think.
Does Wally recommend this too? Just curious.

What is the compression ratio of the wally compared to stock?
It does make sense though to use a higher octane.

His website lists the hyper 30.5's at 16:1 compression.

Any one know what stock comp is?

according to the zenoah owners service manual, the stock 22.5/25.5cc motors have an "effective" compression ratio of 8.8:1 (not the same as static ratio)

here's a link that talks about that difference:
