It's pretty common for planes to snap over in a loop if you pull back too far. The answer is to not pull so much elevator. I don't know the aerodynamic reasoning behind it though.

Afternoon folks. I've been reading all through this thread as I'm going to pick up one of these birds this weekend. I think it's a good deal, found it on CL, it was listed as the RTF for 100, 2 flights no crashes. Pics looked good but will inspect it in person of course. I told them it was new for 99.95 and offered them 65 which they agreed to. So I have a couple of questions for the team of experts here:

What should I look for when visually inspecting the plane?
I plan on testing all the electronics and running the motor up as well, again, anything I should keep an eye for here?
Assuming everything checks out and I go ahead with the deal (seems like little risk for and RTF at $65) I plan to leave it pretty much bone stock, but was wondering about props. I've read a lot of posts on the issue, but hadn't seem to been able to draw any specifc conclusions on a decent replacement prop that will fit and I can pick up at my LHS. From what I've read, sounds like I should pull the stock 3 blade and go to a 2 blade, can someone recomend one from experience that will work well with an otherwise stock setup?

I'm also torn on the gear, it sounds like hand launching is as frought with adverse possibilities as gear landings are...anyone come up with a nice sled that can be dropped right after TO?

Looking forward to your input!

Michael

As long as everything looks good, the motor spins up smooth with no problems and the servos all work as expected I wouldn't think there is too much to go wrong. There are a lot of people that have had issues with the stock ESC's on these FMS planes but there are probably just as many that haven't. It's kind of a crap shoot really. I use a 3S 1000mah on mine and run an 8x4 GWS prop on it.

Crucial, thanks for the input, it is appreciated. Anyone else have other suggestions on props and batteries?

I run 1000mah 3s turnigy batteries and 7060 slow flyer prop. No problems with esc, prop howls a bit on launch at full power ( it flexes a bit and gets cavitation) but under hand launch works fine at 70% power. Same power for roll off ground but your sled idea sounds good as often get tail over on landing on short grass with gear on.

Elevator is very powerful and it will roll almost as quick as a wing. Did rudder mod and need a bit of lead in cowl to balance it properly. Flew tail heavy with just the battery and needs more forward cog than specified in manual.

Have fun.

Ok guys, I got the plane, everything looked pretty good. Put about 3 flights on her this morning, not bad but busted the prop. She had an APC 7x5 on her and I tried replacing with a GWS7035. That prop didn't have enough to get her up. I have some GWS EP8040's but not sure if these will work with the stock battery. Any thoughts?
Thanks,
Michael

Stock prop is a 3 blade 7x6. Having broken my stock prop I'm running an 8x6 SF prop http://www.giantcod.co.uk/slow-prop-...-p-404467.html with a prop-saver - which seems to work fine. Other 8x6 props and other suppliers are available!

You obviously didn't check very hard - I gave a link to my prop, and there are numerous mentions of the shaft size - try this thread search for "prop saver" http://www.rcgroups.com/forums/searc...y=prop%20saver - you want a prop-saver not a spinner, as that will help a lot with not breaking props.

Well, had my first major crack up this morning. 4th flight, going kinda rough, I don't think I have the CG dialed injust yet, and then she noses over and powers into the ground. Splits the fuse right at the cockpit. Gorrila glued her back...little less pretty but should do the trick. I do have a question for those of you who've had like crashes...my wings are a bit loose now and I'm seriously considering glueing them in place. Has anyone else done this?

Aside from that I picked up a Thunder Power 1350mAh 2S but am waiting for Bob's Hobby shop to get in a JSX to TP converter cable for me before I can use it. So far it seems the APC 7x5 works pretty well with the stock setup, though they are substantialy stiffer than the GWS props, and snap like dry twigs if they even get a whiff of ground..lol. I did see that you can get a whole new airframe from NP for 37 bucks...might have to order a couple of those to have as eventual replacements. Now that this one is got her first official cracks I'm going to start modding her a bit and see what works well for me. Sorry no pics of any of this thus far. But if you look at the ones from eariler in the thread (I think it was Frank? - correction - Tartago's) of the split bird, mine looked about the same as that.

My wing has got loose for a couple of reasons:
1) The foam tab on the front has got a bit squashed - solved by dipping it in hot water. It does reoccur, so I'm pondering reinforcing with epoxy, but in a way it's good there's some give in something non-critical, rather than busting the wing (hence why gluing the wing on, or anything more solid may be a bad idea for those of us who crash).
2) The foam holding the nuts in place has got compressed - I found I was tightening the screws more every time the wing moved a bit. However eventually a bad crash ripped them right out, so now they're secured back in with epoxy, which should be more solid.

Neurothief, my wing has come loose twice, both times from crushing and then breaking off the tab that holds it on in the front. I expanded the tab with hot water and then glued it back on with gorilla glue but still had a bit of wobble in the wing. To fix that I glued on some extra foam around the tab and shaved it down until I had a tight fit.
