RE: Midwest Extra 300xs Build
 

bar 98....I'm having the same problem, incredibly tail heavy !!! Right now I have the whole plane disassembled and giving it a good overhaul, and I'm moving everything as far forward as I can. I want to place the fuel tank right over the cg, so there's no change on balance when the fuel level changes. I had my batteries a lot closer than 8" from the ignition module and I had no problems, in fact they were about 2" apart. Right now my batteries and throttle servo are in the engine box, and the rudder servo is right behind the fuel tank. I'll let you know how I make out.

RE: Midwest Extra 300xs Build
 

I was working on mine do day too.. I have the cg in the right spot but I am having glitches like crazy. I will be putting a post up to see if there are some ppl that can help me find out what is making this glitch. I know it is not the cdi that is doing it.. I can only get about 50 feet from the plane with the engine off.. whith the engine running I can get about 25 feet.. I know that is not going to work.

Keep the info comming in.

KI8FR,
How is the antenna routed out of the plane?? Do you have the antenna completely extended, or is it inside of the fuselage? Does it run next to the servos or batteries? Can you post a picture of your receiver installation and the antenna routing?

RE: Midwest Extra 300xs Build
 

If the antenna is ok, I would disconnect each servo one at a time and recheck, Also your servo extensions can cause a person grief at times, Thats another thing to check. If that doesn't show up anything then I would change the receiver and try it. Glitches can be a real bear to find but we both know its better to take home a plane that glitches than one in a sack.
If you can do as Ken said and show us your set up. I had some problems also, But mine was only while running.
I had the batterys to close to each other. also the charge leads needs to be seperated for each switch, Ign& receiver.

Hi mrbassman,

Could you please post the picture of your engine box, I would like to see the throttle servo installation, I have also installed the cut-off servo, ?I would like to see if I can move both to the engine box.

RE: Midwest Extra 300xs Build
 

I really need to get back to finishing mine. Still in the covering stage. I did have a pretty good reason for the detour though. Let me know how this CG issue turns out. I really want to finish this plane, Must stop buying new planes!!!![sm=thumbs_up.gif]

RE: Midwest Extra 300xs Build
 

I don't know how Midwest got the right balance using the Moki 2.10 and just moving the battery.

RE: Midwest Extra 300xs Build
 

Mine come out perfect using a G-62, I lightened up alot and also use a C&H IGN. I don't know what a Mokie 210 weighs but my 62 is just a tad over 4 lbs. Its a great flying plane I might add, My problem is I don't fly it enough.

Which kits are you having the TH problem with the early or late ????

RE: Midwest Extra 300xs Build
 

I am having the problem with the Midwest Extra 300XS, please note that the tail on this version is heavier. I did some test tonight and I have to add around 7 oz to the nose, I will add the spinner and I will try to move the throttle servo and the choke servo to the engine box, but that is not easy.

RE: Midwest Extra 300xs Build
 

There is room on the out side of the box for the servos..

RE: Midwest Extra 300xs Build
 

With my stand offs I could put the servo on the engine box is I so wanted theres enough room ,might be a way to solve some of your problem W/O adding unwanted lead

RE: Midwest Extra 300xs Build
 

I have installed 2.5" stand offs, and the spinner is very close to the cowl, what I will do is to use 3" stand off. Any one know where I can buy it?

RE: Midwest Extra 300xs Build
 

[link=http://www.swbmfg.com/]SWB[/link] has them in incremental sizes.

RE: Midwest Extra 300xs Build
 

Finally I got the right C.G with the DA-50, I added in total 8 flat washers to the standoffs which makes now a better separation between the cowl and the spinner plate and also I added a 3.5" spinner from Dave Brown.
:)

RE: Midwest Extra 300xs Build
 

Glad to hear you got things going your way, I flew mine weekend before last its a nice plane with no bad habits of any kind so far.

RE: Midwest Extra 300xs Build
 

My midwest extra was killed. [:@] I will rebilled her I have the wood I have the tecnolagey. but I do not have a set of PLANS. lol

I e-mailed midwest to see if I can get me a set but nothing back.

Got any ideas on how I can get me a set.

I loved that plane.

Paul

RE: Midwest Extra 300xs Build
 

Myself I would call MW with a request for the plans. Or check to see if there website has a parts list for the plane ,if so the plans should be listed.

RE: Midwest Extra 300xs Build
 

digger44 i have the same plane you are putting together. i lost the book and i dont know what the throws are on all the surfaces, is it possibile for you to print out what the throws are for aileron, elevator, an rudder. also the cg standard and dual rates or 3d. i really apreciate your time if you could possibly do that for me and good luck building your new toy. thank you.

RE: Midwest Extra 300xs Build
 

i brought a 300xs35% and mid west is shut down right now i dont think that thy make that big of a plane can you check around thanks alot

RE: Midwest Extra 300xs Build
 

If you still need this I can scan it or something. Sorry I didn't see this sooner.

RE: Midwest Extra 300xs Build
 

hello. I got a hold of Midwest and they send me the book for it.
I thank you for your concern.

RE: Midwest Extra 300xs Build
 

What about a set of plans? lol Mine crashed and I have to rebilled it

RE: Midwest Extra 300xs Build
 

I added more modifications to the fuel tank place and servo throttle position.

It flyes really nice, easy on landing.

RE: Midwest Extra 300xs Build
 

Nice mod on the tank bar98, what size is the tank? I have thought of doing the same thing with mine but I would like to add both fuel and smoke on the CG ,and i'm concerned about enough room. Another thing that has stopped me is the fact the plane flies so dang good with the tank in the original position I hate to mess with it. One of them if its not broke don't fix it deals *LOL*

Digger how is your project coming along ,its been a while since you last posted any progress.

RE: Midwest Extra 300xs Build
 

Well, not a lot of progress. Still in the bones ready to cover. I'll get to it one of these days I'm sure. It's kind of on the back burner for now. I have a 35% Carden now that I am working on hopefully to maiden in a few weeks if time permits. I really do need to finish the Midwest though.
