What is the difference between a 370 and a 480 motor?  Or even the various
classes of motors?
What does the gear ratio mean?  Like a 3.67:1 (370) and 2.50:1 (480).
what is the difference between a 4G/4D/6D motor?

I am in the United States and my operator says this is not a working number

Has anyone read Flyboys? The ones that were captured and shot in Chichi
Jima. What an eyeopener if it is accruate. Good old Silent Cal.

Having just recovered from "I was out shopping with my mother and we saw
.......... a suite on sale for £1800 !!!" How many brownie points would I
gain if I agreed to the purchase. Would the decorating go on hold for at

We are having discussions in our club ay present about whether or not to
allow jet turbines to fly at our club field. We are in a reasonably noise

The news group seem a bit slow so I thought I would bring up another
question topic. I was looking at servos the other day and noticed that they

I just purchased a GMS .61 ringed engine for that old P-40 I'm
building. I'd like to use an in-cowl muffler, but Hobbico (the
distributor of everything, it seems) tells me that no headers are made

I have inherited a older Cirrus Radio and such.  It was mentioned to me that
the Cirrus radio could not be used anymore because of the allowed
frequencies have changed by law or something like that.  Does anyone care to

I recently was given an ARF Pitts special that someone ordered from Tower.
While going over it with a fine tooth comb looking for ways to make it
better and measure up to MY standards, I discovered something odd.
The landing gear was only 5/32!  That is just not good enough as it ...

Can anyone recomment a small size, low cost, low power GPS receiver with
velocity, position and height serial data output  ? (It will be used in a
model airplane for data logging)

Just got a copy of Pre Flight which works through the MIC input of the
sound card. Very good too.
Tested on both a 6EXA and a 7CAP. My question is -- can I run the Tx
with the Xtal out so I'm not actually transmitting anything or will

I just got a new 8ah Ni-Cad F cell to repair my golf trolley battery, I
think they are made by Yuasa.
I trickle charged c/10 it for 20 hrs as normal as you do, then
discharged it with the Supernova and it only put out 4ah, discharging at

Anyone know what size of floats should be used with the hangar 9 80" ARF
cub? or barring that, know the distance from the engine thrust washer to
the rudder hinge line?
