Gene,

Have you settled on THE brushless motor for next year's pylon season?

Need to let Barb know so she can get some in before the season kicks off.

Prices have shot up on several of the candidates...

I have a couple of new samples coming in, following the Chinese New Year, probably next week. If it works out as I expect, I would probably do a bulk buy, and turn them over to Barb to distribute. I don't mind handling it this way, if it means a $20 motor rather than a $40 motor... assuming they quality and performance are there.

I considered an outrunner, as the prices are steadier, but the efficiency is not there, and as pointed out earlier by John, the gearbox shafts are much easier to replace.

I just fear that if we go to 3s LiPo, the cost and volitility can get out of hand. For the most part, the 2/3AA cells have done well, as long as guys remember to break the packs in.

Gene,

Just to confirm, we ARE staying with the 8-cell 2/3AA NiMH packs for the 2007 season, right?

Have you arrived at a brushless motor of choice - inrunner or outrunner?
Any idea when we will be able to purchase them from Barb?

Thanks!

It's going to be tight. I have not received the samples, and delivery is about 2 weeks...

Yes, intend to stick with the 8xNiMh, or 2s LiPo...

OK, The motors are in. There are some at Hobby RC. Barb has agreed to handle them for us.

I also got a few speed controls (12a), and some stick mounts.

The prices are:
Motor: $25
ESC: $17
Aluminum Mount: $6
Plastic Mount: $3

More is coming. I have just got the ESC's, so I need to get them to Barb.

The 1st raceday is Sunday, 4-29 @ 5pm. This will really just be a warm-up and cobweb cleaner, so don't worry, run what you brung, and get some testing done, if you want.

The rules will be basically the same. Last year's stock EPS350's are still allowed. The batteries will remain 8xNiMh, or 2s LiPo. I suggest the 8x2/3AA NiMh packs, or a ~2s2100 LiPo. I'll likely be running the LiPo this year, as my NiMh packs are pretty weak.

Technically, the NiMh pack should have an advantage for power, but it is just a tad heavier. You might be able to balance the plane with a LiPo pack smaller than 2100, but I couldn't. Using an E-Flite 9x7.5 prop, I pulled 11.5a for 5700prm. This compares with the stock motor of 10.8a for 5400 rpm.

My test flights seem very good. I have not tried other props, as this just felt so good.

Here's the programming instructions for the Tower Pro esc's I got in (Barb now has them).

Updated manual to remove Chinese fonts...

We got our first event under our collective belts last night, and I believe everyone had a ball.

We had a nice mix of new and old motors, new and old airframes, and NiMh and LiPo batteries. All seemed very competitive. A lesson was learned on batteries... cycle them and check to be sure they can perform! After sitting all winter, some had trouble getting any run time. a few cycles on a Triton or similar cycling charger should wake them up and tell you what condition they are in.

We had a few crashes, but luckily (for the most part) the 5 minute epoxy kept everyone in the game.

The newest change was cut judges. We had 2 heats of 4 last night, and the 1st heat judged the 2nd, and vice-versa. This worked very well, with your's truely leading the pack in cuts and DQ's Smiley By the time the main race came around, however, the pack thinned to the point that even I could win!

Duane did a little heeby-jeebie curse on Chuck's plane, and stole his mojo. Doug, flying Duane's plane ran out of mojo in the main (2 cuts you're out) Bill would have won, except for a cut. Pat nipped at my tail, keeping me honest the whole race. Bob left early for some reason? John had 'issues'.

Fun was had by all, especially the spectators. The birds, who had built nests in the shelter cieling were the only ones unhappy.

Barb has motors, mounts and speed controls. I have a few more mounts and motors to get to her, and I'll pick up the stock for the next meeting, or have her bring it. Again, the new motor seems to be just about even with the old, so no penalty for using the old, until it wears out.

Again, we get these events started at *5pm*, as stated above. a few guys came out rather early, and got in some practice. In one case, perhaps they used up all the 'good stuff' they had a little too early Smiley

Yea I had a few "Issues" New batteries not cycled enough,  Dumb thumbs and a collapsed wing.  I do want to thank all of you for waiting and helping me to re-engine the plane, Fix the Plane, and selling me a  9 X 7.5 prop.  Bill thanks for all of the glue. You might want to check your tool box closely and make sure you have all of your tools .
See you next race, hopefully with a new airframe!

This is part of the Electric Pylon racing series at the Indy RC South field using GWS Corsairs.
Racing is scheduled to begin at 5pm.

The rules will be basically the same.  Last year's stock EPS350's are still allowed. The batteries will remain 8xNiMh, or 2s LiPo. I suggest the 8x2/3AA NiMh packs, or a ~2s2100 LiPo. I'll likely be running the LiPo this year, as my NiMh packs are pretty weak.

Still not sure what Duane did to my plane...  Smiley
Actually, my current theory is that there is something wrong with the new Spektrum AR6100 receivers (v1.2).  They sometimes take as long as a minute to initialize when power is connected.  I suspect that the receiver went into failsafe, as everything else appears to be working fine.

Regarding start time, I've added the rest of the pylon races to the website calendar and included the start times.  Smiley

Hey guys,

Is the racing open to non club members? I just picked up one of the BL motors from Barb and thought I might have a go at racing with you. Is the Corsair still the plane to fly?

Thanks, Matt
