LaBam, Sent you another PM. I've been out of town on business. Let me know if you are still interested.

RE: Does anyone know of a good 1/2A or similar size glow powered heli?
LaBam, I'm in the process of going through my father's estate and one of the model helicopters that he had was the Hirobo MH-10. As I recall, he originally had two of them and crashed one. From what I could tell of what remains in the boxes, there appears to be at least one complete MH-10 and about half the parts from another plus, including at least one OS .10H engine. I haven't had the time to inventory all his stuff yet, so I can't be more specific. If you are interested, send me a PM and I'll see about getting some pics and a quick inventory of the parts.

RE: 12z swich reposition
Uh, Bax, pardon me for being a little dense, but what's the point of us being able to swap out the switch positions (a Feature?) if the transmitter has to be sent back to Futaba service to reprogram the switch in the software?

R608FS battery voltage
Hi, I just recieved a Futaba TM8 module and a R608FS reciever that I am going to use with my 8U transmitter. I need to know if I can run the R608FS on 6v like my 72mhz recievers, and if so does it need to be regulated, even if I'm just using a 5cell nicd or nimh battery? Thanks

MC did you get your Giant Stinger up in the air yet? I'm interestes in what you think of the performance of those HD servos in the air. Robert

RE: CMP Zero Makeover
MC I don't have the Zero yet. My buddy has one partially compleated that he lost interest in; and we are negotiating a deal. That's what origionally got me onto this thread. I'm currently working on a scratch built P-51 from a Dan Santich plan for which I have a set of Byron mustang retracts. The other problem I have with the Zero deal is that it needs a set of retracts. I heard that the Robarts were out of stock and back ordered, so I'm looking for alternatives. Jim mentioned that he is using H-9 retracts which I hadn't thought of. I don't have CG info on the Zero, but it should be at about 25% of the mean aerodynamic chord (M.A.C.) which I should be able to calculate if I have the length of the root and tip chord, the distance from root to tip, and the leading edge sweep angle, or the distance from the leading edge at the tip to a line drawn perpendicular to the root at the leading edge. (I hope that made sense!) This gives the planform layout from which the M.A.C. can be found. Jim, how much work was it to retrofit those H-9 retracts, and which ones did you use? Robert

RE: CMP Zero Makeover
MC, I thought that the servos seemed a little noisy too, and I also pulled a gear train apart to check it out, and could find nothing wrong. I did notice that the gear teeth are all straight cut while some of the better quality servos that I've been used to using have some helical cut gears in them. That could be the difference right there as helical cut gears run smoother - you get what you pay for. I think that they will work just fine though for most applications except 3D. I am very interested in how they perform in your giant Stinger. I used to have one of those with a G-62 on the nose and it had various servo combinations in it over the years. I had a single Hi Tec HS-635 on all the surfaces except rudder, running at 6v, and it flew fine; although it was much snapier when I later changed them out for HS-5645s which is what probably what led to its demise. (Left wing broke about a third of the way out at 200ft!) If you're running the stock strip ailerons, two servos are probably overkill, but it won't hurt anything and it will be interesting to see how well they stay in sync. What did you use to match them, just the TX ?? Robert

RE: CMP Zero Makeover
Ok, here are the pics of my servo wire jig. There is also a jpg of a line drawing of it that I started. I think that between the pics and the drawing, you should be able to figure it out. Use a 25 watt iron with a fine tip and keep the tip clean. A solder sucker is also useful but copper braided wick will work too, (to unsolder the old leads), it’s just a little more awkward is all. My average time to change the leads is about 7 minutes when using this jig. Take your time and use just enough heat to do the job. I’ve done 5 servos so far with 12� leads. The next set will have 24 – 36� leads or what ever is required to reach all the way to the receiver. Good Luck! MC – Did you get your giant Stinger up yet? I’m anxious to hear how these servos worked for you! It’ll be another week or two until I can try mine out… too many projects and too little time! Robert

I've got a family thing to attend over the weekend I'll post the pics of the jig when I get back.

RE: CMP Zero Makeover
I too got in on the 10 servo deal; it was too good to pass up. I just hope that the servos live up to their billing. The output shaft on the HD2250A is definitely larger than the Futaba or HiTec‘s shaft. I tried some Airwild JR arms that I had and they wouldn’t go on. The MPI arms that clamp on the output shaft look like they might work though. MC, what brand JR arms did you use? Since I had some 12� 22ga Futaba servo leads on hand, I decided to convert 4 of the HD220A servos over to the heavier leads. Note: You will definitely need a low wattage pencil type soldering iron with a fine tip. It wasn’t too difficult, as I was able to do a credible job by hand on the first one, but since I had potentially 9 more to change I decided to make a simple jig to do the others. If anyone is interested, I’ll try to post pictures and a drawing of the jig. The jig definitely makes the process easier. It occurs to me that there is an added benefit to doing this; as you can now make the servo lead any length that you want, there by eliminating one connection and its associated voltage drop! (More delivered voltage = more power.) Robert

RE: CMP Zero Makeover
Hi Guys, I thought that I'd put in my 2 cents here, as I just got a set of the HD2250A servos from TBM. The servos seem to be pretty strong, but I was disappointed at the servo leads used. The leads appear to only be about 26ga and I would have expected at least 24 ga or better yet, 22ga, considering the current required for a torque rating of 165 in-oz @ 6v. It also makes the servo really cheap looking...Yeah I know, they are cheap servos, but how much extra would the heavier wire have cost? The plastic servo arms are a little short for my taste, and TBM suggests on their web site that metal arms should be used, but don't say which ones to use. I've tried Futaba, Hitec and JR arms and none of them seem to fit. I'll be trying these servos in a profile test plane soon and it will be interesting to see how they perform in the air. If anyone else has gotten their hands on these servos I'd like to hear about it. I was going to use them in a Mustang and a Zero that I have in the works, but I'd like to get a feel for their performance before I commit them to an airframe that I have a lot of building time in.
