Contrary to popular belief and/or opinions, I was just running a new stock 350 motor. Just ask Ivan - he was the first to inspect it.  I did make a couple of changes from the first race I attended, that did seem to help in this last race. I'm sure that Duane, the Intimidator, will be leaving me in the dust when he installs that new motor!!! |

It was very hot at the field for the 4th pylon race, but we still had five participants. Bob Badger, Brian Merrell and Ron Allanson were the new faces at this race. As expected, Duane's new "stock" motor pulled him back up to the front of the pack. Fortunately, there were no mid-airs today, but Ron Allanson's bird did go down in the corn and Brian Merrell's had a bad launch on the last heat. There were several close calls though. At one point, I passed behind Bob Badger's plane and mine disappeared! It did become painfully obvious that we desperately need cut judges for future races. Things got completely out-of-hand today with people blatantly cutting inside the pylons. |

Agreed! I'm hesitant to post the recorded results, as everyone there was sure that the documented winner (and several others of us) cut at least one turn |

So, what are you suggesting?
Do we throw this one out?

Hi all- I have enjoyed every race so far this year, and yesterday was no exception. There did seem to be more pylons cuts Saturday than in the past, I might even have cut one myself!  Having said that, not sure there is anything to "throw out". We have no big prizes (matter of fact no prizes period) and no yearend recognition planned at this time. It may be good to continue a very relaxed approach to our pylon program the rest of the year as we sort things out and hopefully get more people involved. Cut judges will certainly add more discipline to the flying of everyone. However, as Chuck demonstrated at the prior race, and as I demonstrated yesterday, a fresh motor gives you a big advantage over others with motors having more flight time. When we add more discipline, we probably should go to brushless motors in the interest of giving everyone a more equal footing in terms of "horse power"! Duane |

Here's the preliminary test result. I'm not happy with the BM2408-21 both from an efficiency and supply line aspect. If GWS will give us a slightly hotter wind, we'll be golden.

Gene,
For the baseline motor, EPS350C-C, you need to list its performance on the 8-cell 750mAH 2/3AA NiMH pack, not a 7v pack (2 cell LiPo).
I for one would not want to settle for less power/speed if/when we switch to brushless.

Actually, I could test them at 6 volts or 12 volts for all it matters. The results are linear and relative. 7v is the common 2s baseline. With the 8x2/3aa packs we start about 8v, and drop to about 6.5 at the the end of the race...
As I said, none of these are the golden ticket. Everyone else seems to want to use 3s packs. If we want to exclude the non lipo guys we can too. I personally don't think we need to.
As always, I'm wide open for suggestions!

Bummer, looks like I'll miss this one...
This is the same day as the Float Fly out at Roy Wilson's farm.

Aww Man, and I am going to try out a new brushless combo... May make it to the field with it tomorrow.

Gene,
Tried the HiMaxx 2015-5400 in my Corsair with the 8-cell Kan750 pack.
The GWS 9x7 prop pulled about 14A WOT.
The E-Flite 9x6 prop pulled about 14.3A WOT.
I'm going to see if Barb has any smaller props to try.
Also, I have the 2015-4100 with the HiMaxx gearbox.
It has three different gear ratios included, so maybe it might be a possibility as well.
Chuck

Barb had a GWS 8x6 prop (the orange one).
At WOT with the 8-cell 750mAH NiMH pack, it draws about 9.8A.
This gets the amp draw down where it should be for the motor/ESC, but I'm not sure how well it will fly on the 8x6 versus the 9x7 or 9x7.5 that we normally use.
I won't be able to make the race today, but will try to stop by before you guys finish so we can try to run this setup against the 350-C brushed drive.
Hope the weather cooperates for the race!
Chuck
