Batteries Available
If anyone is interested I have 7 sets of Thunder Power 45C 4400 10S Flight packs available. It's about a 50/50 mix of 1135g/1140g and one at 1130g. 3 have 60 cycles, three have 14 cycles, one at 38 cycles, and one at 22 cycles. All are in excellent shape.these are the G6 Pro Performance series batteries. I also have one 5000 10s 45C at 1330g pack with 13 cycles. These are all rated at over 300 cycles so they are all very low time. I have 2 Rhino 4900 with approx 100 cycles that are still very strong & cheap. All at or less than 25% of new! PM me if interested. Dick

Hey Chuck Can you confirm the Georgetown Pattern date. I thought it was the 23 & 24 of June. Don's website shows June 30 & July 1. Dick

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes
Brian There are no pic's as the props pretty much look the same as un modified except for the tips. What I did was take the new APC contra drive electric prop and etched the shape of the tip onto the catbon and ground it dowm and then finished with a final sanding. I then sealed the tips with thin CA. This also gives the tip a durable edge. Dick

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes
Hi All Quick updqate on my prop experimenting. The cut-down 22x22/22x20 set of props really turned me on to modifying and playing with all my carbon contra props. I had 14 carbon props laying around and I had a good time grinding mixing, modifying and matching these props. Here are my findings and results in no particular order: 1. I learned that tip shape is a very important factor in prop efficency and noise. 2. On the Contra Drive making the front prop 1/4" longer than the rear prop really made the drive much smoother in performance. Although I can't prove it with hard data I feel it also made the drive more efficient. 3. I learned that matching props to specific set of wind conditions can produce very desireable results but there was a penalty as each set requires a different throttle, idle, and brake setup. I ended up with three sets of props that I can use for three wind conditions. All props have been tip modified utilizing the APC tip pattern. All three sets have been modified in length with the front prop being 1/4" longer at each tip. This was accomplished by cutting the rear prop on two sets a 1/4" at each tip. The net results are as follows with the defined wind condition. 0 to 10 mph wind condition = 21.5x20 Rear & 22x18 Front 10 to 15 mph wind condition = 21.5x20 Rear & 22x20 Front 15 to 25 mph wind condition = 20.0x22 Rear & 20.5x20 Front All of these are flown on the 9.89 to 1 gear set. Some of what I accomplished speed wise could have been duplicated with gear sets but it's a lot easier to change props at a contest. Plus the diameter changes along with changing the tip shapes really quieted the props down and made the whole Contra Drive smoother! I really enjoyed experimenting with the props and learned a lot. Now, if I could only learn F-13!! Dick

RE: Sebart Wind S Pro
Yes, I fly with a very minor mix for down line and with the Contra Drive I use a .5 to .6 down thrust on the contra which takes the going to canopy out of the up lines. I am also using a 28% Mac for c/g which effects everything. Dick

RE: Sebart Wind S Pro
I agree, 0-0 not a good wing stab setup for Wind S Pro for me! I use .5+ for wing and set stab at what ever it takes to get trim out of stab elevators. This process usually ends up with around .1+ Dick

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes
Hey Brenner Modified my carbon props as indicated above and was able to complete the cut and finishing in under an hour. Had a good afternoon to test them as the wind started out around 10 mph and increased over the afternoon to a steady 15 gusting twenty. I cleared my ESC logger and made five flights with the first flight with my original setup of stock 22x20 rear and a 22x18 front. All flights were logged and down loaded. The second,3rd ,4th and 5th flights were all done with the modified set of props. Here are my observations and data with all flights being F-13 schedule and 5000 mah packs on 9:89 to 1 gear set: 1. Max current 96 amps max for only very short times with average 42 amps. 2. Max ESC temp 140 derees with average at 117 degrees. [80 degree day] 3. RPM max was 4670, previous was 4710 not much different. This was very surprising! 4. I immediately felt the increase in speed at all throttle stick positions. I would agree with Brenner when he said it was the fastest 2m pattern plane he had flown to date. So much so that it took three flights before I could get a handel on throttle stick position for normal cross box and vertical up lines. I did not get my snapp speed throttle position until the last flight! There is so much difference I am not sure it is going to be practical to switch sets back and forth for different wind conditions! It really screwed up my maneuver timing. 5. Aircraft in flight was definitely quiter but would need more testing as I had a crosswind on my back blowing sound away from me. 6. I increased my braking to 40% and the downline was still not as good as the longer props. I will test more at 50% and up to see what happens. 7. One thing I really enjoyed was the greatly increased ground clearence with the shorter props! That's about it until I get more flights on this combination. One thing I want to do is take 1/2 inch off the rear prop of my previous set [22x20] and reshape the tips of both front and rear props. This will give me 1/4 inch longer tips on the front [22x18] prop. The tip shaped I used was exactly the same design the APC's had as I think there is a sound and efficiency benefit to this shape tip. That's about it for now. Questions and comments welcome and will report more when I get results. Dick Late note, all batteries took between 3100 and 3300 mah when charged. Will definitely be able to use my 4400's!

RE: Power issue
Did you try to re-arm on the flight that lost power? You would have had to go to low trim and low throttle and when your up to your butt in aligators it's hard to think about everythig but it sounds like it may have worked. Also how do you have your fail safe set up? You may have momentarly lost the Rx and it shut the ESC down. That would require a re-arm to get power back. Not sure what the data logger woud show on that kind of event.

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes
Hey Brenner Looks good. I am currently running the 9.89 gear set with the 22x20 rear and the 22x18 front and only use 2900 to 3000 mah on my TP G6 4400's flying the F13 sequence. I think the Neu motor is more efficient than the Hacker 13 wind. I do not believe I would have any issue running the cut down props as far as staying in the 80% rule with the 9.89 gearset! I will let you know as I am cutting down a set as we speak. Dick

RE: Suggestions on the HiMax 6330-200 Motor prop adapter
Joe Most any adapter will work so long as it fits the HiMax drive shaft dia. make sure the adapter drive is the same dia or bigger as the prop of choice. You can always ream a prop larger if you are careful and use the proper ream size. Then adjust your firewall mount for the length required for the specific adapter you have. Dick

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes
Brenner & Malcom I am sucessfully using 30% brake on my CC Phoneix Ice HV 80 II ESC. I am using the 22x20 rear and the22x18 front Carbon props. What I have determined is that anytime the props are turned in opposite direction thay are engaged with the motor therefore an applied brake torque should be felt at the windmilling props slowing them down if you are completely off the throttle stick.
