Thanks Bob, good to know.

On the topic of engines I was of the understanding that when a person purchased an engine from a manufacturer you essentially received the next engine off the line, an engine that was manufactured to a set of approved tolerances, tolerances that are very tight and fair for all. I have at the same ti...

Kevin Moorehouse will not be attending, have a good race.

Kevin Moorehouse will attend, teaming up with Randy Smith and Doug Houston.

I discovered the reason for so much propeller run-out on some propellers. Much of it seems to be from the drilled hole not being true to the molded centres. I found that when I had drilled out Q500 props I drilled / reamed holes to 5/16 “ which is too tight and will lead to misalignment. To fix this...

I found a flaw in use of this ViFly Lost Plane Buzzer

When it is plugged into the RX it consumes its own battery and after a while the battery is drained, and will not be recharged. These things appear to need to be unplugged physically when not being used.

I found a few pictures from a race in Calgary in the mid 80's. I think it was 1986, but not positive. The Western Canadian racing circuit was pretty active in the 70' and 80's.

I am using the molded centre as well the front and back face, as would be used in clamping a prop to an engine, I am not using the drilled hole. I have been playing around a bit to understand what is out on a prop that has .022" of difference on the leading edge high point, one blade to the next fro...

Hi Fizzwater2 Thanks for checking the formula, I have rebuilt the table, and have checked a number of propellors, you are right a good light behind helps to see the closing angle between protractor and prop. I built a worksheet to log props and help see through all of the numbers to determine averag...

I have wondered for while if there was value in having a Prather propellor gauge, but was never ready to buy when they occasionally come on sale. That and having more time than money (retired) I thought I would make my own digital prop gauge. I have attached a couple self explanatory pictures in cas...

Thanks Greg, I may try to fix myself, shipping to and from the US / Canada is unpredictable.

Thanks
Not sure who made these, it was probably in the paperwork, I already bought a new one, thought I could have a spare, at the same time since I’m in Canada and the cost of mailing stuff across the border usually makes it simpler to throw out if it cannot be fixed easily.

I have a FAI style glow driver. It went up in smoke a couple years ago and wonder if it is worth repairing. If you have an idea let me know.

See attached picture of area that overheated.

Thanks

I tested out a jumper around the light sensing chip, and it works. I connected the device to a 2S LIFE battery for 2 hours for a charge and then placed the device in a dark spot for over 4 hours. After 4 hours it continued to operate, although the interval between beeps had extended too 8-10 seconds...
