You're Welcome. I had fun and it was enjoyable to see everyone else have fun.;):):):)

RE: RedWing MX2 Build
 

Hey raf that mx2 looks superb.

About your aileron servos does sound like a binding problem. if its the ball links being to tight maybe cause they're dry? I allways put a wee bit of vaseline on my ball links to loosen the inner metal ball as i have encountered many that get stuck for some reason when they're new. Other than that i'm stumped.

Cause with 236oz per aileron that has insane power for that.

RE: RedWing MX2 Build
 

I agree with you, most likely that may be the root of the problem. I'll let you know what I found out soon.

RE: RedWing MX2 Build
 

Okay let me know if that tip worked on your ball links.. But from your description definedly sounds like tight ball links or too tight linkage causing like you said binding..

RE: RedWing MX2 Build
 

I got a question.

How big is the tank included on the mx2?

RE: RedWing MX2 Build
 

I believe it may be about close to 12 ounces, but I am not really sure since I didn't pay much attention to see if it was labeled in the tank. Most probably it is graduated in milliliters and 12 ounces are roughly 355 milliliters.

RE: RedWing MX2 Build
 

yep a little under 12oz, 350cc (11.834oz) to be exact.

RE: RedWing MX2 Build
 

Raf can do a lot of things and one of them is putting the radio gear in the neatest of anyone I`ve seen. Thanks again for letting me maiden it for you very good flying plane.

RE: RedWing MX2 Build
 

Hey Raf. Have you had a chance to iron out your wing servos yet?

RE: RedWing MX2 Build
 

Ohokay so rougly 12oz in the tank..
Um how big of a tank did you guys use on this plane?
Also will there be space for maybe a smoke system in the beginning or later?

RE: RedWing MX2 Build
 

I have the Sboch but I used the the tank that came with it. You have room in the can tunnel underneath for a smoke tank but I wouldn't want to pay the weight penalty on a plane this size. I have some friends that say that they will never put a smoke system an anything smaller then a 150cc plane. Of course that is what most of them fly and do it well.

RE: RedWing MX2 Build
 

These planes would be a little small to try to stuff in a smoke pump and tank. I have used smoke systems on two 50cc sized planes and both had plenty of room and both worked really well.

RE: RedWing MX2 Build
 

Hey Night Scream I agree with Old Tom and Vanguard in that this plane is too small to stuff a smoke system in it. It's possible but I would not advice it if you want to obtain the best 3D performance from this plane.

RE: RedWing MX2 Build
 

I believe I have the problem under control. I PM TJ yesterday and he gave me some good advice. Basically I found out that (1) one of the aileron servos was kind of loose in its mount and after tightening it it improved somewhat but there is a lot of sloppiness when centering . And (2) TJ suggested and I agree completely with his assessment that the analog servos (Power HD-1501MG's) are not as precise as digital ones from a more recognized brand. Although these servos are advertised to have a death band width of less than 4 microseconds, of which I am not so sure. The best that any analog Hitec 3 pole ferrite motor servo con resolve is 8 microseconds. That leads me to believe Power HD claims are somewhat exaggerated. So this may be the best I will ever get from these servos.

I am looking at alternatives to replace these servos. By the way; what servos are you using in the Sboch ailerons? Price wise coreless motor driven servos are a little prohibitive in price. I think Hitecs HS-5645's MG are a good alternative at $45 bucks a pop although they are ferrite cored motors with 8usec death band width. Power HD have the DS 090M's and Redwing carries them for $35 bucks. Check the Redwing video [link=http://HERE]http://redwingrc.com/video/90mvid.htm[/link]. I am undecided and open for suggestions.

RE: RedWing MX2 Build
 

Smoke can be done on this plane but like the rest of the guys said you will be paying a weight penalty...   I'd say a little over a pound (including the extra tank with smoke oil in it).  you will also have to put a smoke nipple on your muffler.<div>
</div><div>it could be done, yes your wing-loading will go up a tad bit, and pull out of a hover will suffer, but I don't think by a Ton.  It depends on what type of flying you will be doing... 3d will be possible... this plane is light guys so I think there is room for a little extra weight on board.  </div><div>
</div><div>At. 9.5lbs AUW the wing loading is about 21.5 oz per sq ft, Add about .5 lbs of fuel and your at 10lbs loaded, then add another 6oz in smoke stuff and another .5lbs in smoke oil, now your AUW loaded is about 10lbs 14 oz.  And that gives you a wing loading of about 24.5 oz per sq ft.  Which is still not bad.  (this is with using the same battery power for your smoke system as your RX power)</div><div>
</div><div>
</div><div>although the plane will not float as much (just speculation on that) I actually think it can pull it off.  I guess the best thing to do would be to just toss in a extra pound of weight in one and fly it to see how it performs and if it still is good then pulling off smoke would be no problem.</div><div>
</div><div>and AirTech, the Power HD DS090M servos are very good.  I have about 25 or so flights on mine now and they are flawless, I have some video of them in the plane and just running them on the surfaces and you can tell they are fast.  Once I get a chance I will try and edit it and post here.</div>

RE: RedWing MX2 Build
 

I have The Power HD DS090M on my Rudder. Very fast, plenty of Power. I'm using analog Hitech 645s on the rest.

I to had problems with the Aileron servos not centering. Couldn't keep it in trim. I just replaced the servos with newer ones and had no more problems. The ones I took out were about 5 yrs. old and have been through the ringer.

I decided to test the Power HD on My Sboch and so far I like it a lot. I would choose them over the Hitech 645. I'm still not ready to replace my Hitech 5645 with the Power HD. But if I didn't have any servos for a plane I wouldn't be afraid to put the Power HD in my 25% or 28% planes.

RE: RedWing MX2 Build
 

Thank you guys, appreciate the feedback. I feel more confident in trying Power HD servos once more. I will be ordering a pair of DS90M's from Tim as soon as I log out. And by the way TJ: Have you tried the Hawk props on your planes? As far as aesthetics they look very nice, and the price is excellent.

About the smoke tank question I do agree that a smoke system will look awesome on this size model, as long as you are willing to sacrifice a little performance. Hope Night Scream decides to install one on his MX and then share his results with all of us. I like smokers in any model and being more of a sport pilot I am willing to try it on my MX.

RE: RedWing MX2 Build
 

Hey Air tech,  Thats what I'm running on the plane in the video... I have tried both sizes the Hawk 19x6 and 18x6... I have a 18x6 on my plane now, but I like both props, I'm still in between on which one I like better.  They are good, I like them they come with a good finish, pre-drilled @ 10mm and well balanced, you still should throw them on your balancer to test because each prop is different.  The price and performance is great.<div>
</div><div>I Tached my JC-28 EVO the other day with the 18x6 and was hitting 8700rpms.</div>

RE: RedWing MX2 Build
 

Wow....! 8870rpms! That prop seems to be a good fit for the JC but that also says a lot about the engine; that's quite a strong powerplant. For sure my next 25% will have a JC on the nose. I am sorry to have found too late about the Hawk; I just ordered a CF Biela from A/C International five minutes ago and a pair of DS090m's from Redwing right before that. I know the Biela is an excellent fit on the Evolution 26 since I had one on the same engine flying a Wild Hare Baby Edge like a rag-doll, and that plane weighted a little over 11 pounds. I may order a Hawk on my next month R.C budget anyway to try it out.

Hey TJ do you have any new videos of you hucking the MX2? With your permission I will like to headline it on our club web page. Could you send me the embedding code for the video so I can run it on our home page?

RE: RedWing MX2 Build
 

No new videos yet, but if I get out to the field tomorrow I will try and get some...<div>
</div><div>yeah, that JC is a little monster! I was so surprised when it tached 8700, I also use the RCexel tach, that hooks directly to the ignition module so its pretty accurate. </div><div>
</div><div>I'm not a real pain about props, I just get one throw it on and if it feels good I fly with it,  and with that said the Hawk prop feels good so I fly with it, why pay more??</div>

RE: RedWing MX2 Build
 

Hi, i´m looking for some info on this plane..

I´m interested in getting my first gasser.. this is a posibility!
My flying style, leans more towards precision acrobatics than 3d, but its still fun to try and hover, and tumble etc
i´m currently flying my great planes extra 300sp non stop and absolutly loving it.. does anyone know these 2 planes to be able to tell me if they are "comparible"?
finally would I be able to use it in f3a competitions (i´ve not competed yet but its about time!!!).

Hoping so, in which case as soon as i´ve pulled the cash together will be getting one shipped here to spain :D

RE: RedWing MX2 Build
 

I recommend the Sbach for precision flying over the MX2. It is a little bit bigger and it grooves nicely. The MX2 is lighter and is better for 3D.

Sorry I can't help with comparing it to the GP Extra and don't know much about f3a.

RE: RedWing MX2 Build
 

ah sorry, F3A is the european name for IMAC (if I understand correctly).

RE: RedWing MX2 Build
 

Well if i figure out how to install a smoke system and how to control it.. since its a completely mysterious area on planes.. I have seen planes with smoke system but have no idea how to set it up..

But question how big of a tank doe sone run ina smoke system also do i need to use a pump for it?

Hey raf. why not try the 5625MG servos they cost the same as the 5645 but are slightly faster..

RE: RedWing MX2 Build
 

F3A is the equivalent of AMA Precisions Aerobatics. And I am sorry to say these planes; both the Sbach and the MX2 are designed mainly towards 3D and or IMACC competition.

Pattern is another name for Precision Aerobatics. It come in two flavors: AMA style pattern (National Society of Radio Controlled Aerobatics) and IMAC (International Miniature Aerobatic Club). There are several differences between the two types. IMAC rules require scale-like aircraft and AMA pattern requires a plane specifically made to fly RC aerobatic maneuvers. Different maneuver sequences are used in each style. AMA style pattern has been around for 30 or more years, while IMAC is somewhat newer.

Pattern (F3A) requires a plane designed specifically for that purpose. For example the AMA Rule Book part 4.3 reads "[u]Weight and Size[/u]: No model may weigh more than five (5) kilograms (11 pounds) gross, but excluding fuel, ready for takeoff. Electric models are weighed with batteries. No model may have a wingspan or total length longer than two (2) meters (78.74 inches)." Those are AMA rules and I believe they were adapted from the rules of the Comision Internacional de Aeromodelismo which is a chapter of the Fédération Aéronautique Internationale. In order to enforce this particular rule planes are inspected by placing them inside a 2 meter square box. Most F3A designs tend to satisfy this rule and maximize the tail moment in order to perform the most exact and crisp turning maneuvers usually have similar length than wingspan (2 X 2 meters)

I don't know of a national pattern association in Spain, all I have found out in Europe is the [link=http://www.gbrcaa.org]Great Britain R/C Aerobatic Association[/link] they may be able to direct you to an Iberian pattern club. If you are interested on IMAC style competition in Spain the only source I know is the [link=http://www.copacuadrangular.com/node/109]Copa Cuadrangular[/link] and for this purpose all Redwing models will prove to be very competitive if you like to compete in the Basic to Intermediate levels. Advance level competitors in the USA fly mostly 38 and 40 percent ships mostly because impression points: A bigger airplane appears to be flying slower and they are much more stable and solid flying in any wind condition. Hope this clarify your intentions.
