I have three of the CMPro products but the P40 is not one of them. I have the 40 size Super Chipmunk, 40 Size Staudacher S-300D, and a 50 size Katana. Generally I've been pretty happy with the products and even more happy with the distributor I bought them from (www.jet-hobbies.com).

I built the Super Chipmunk already and had a problem with the landing gear that is wing mounted.

Other than the LG, it's a nice plane and flys well with an OS 46FXi in it. Fairly simple to put together (took me about 40 hours). I crashed it the other day and it's in a bit of disrepair but I can get it flying again. I'd be careful about getting the Super Chipmunk until the manufacturer beefs up the wing area like I did on the thread. They are supposedly looking into doing this but it'll be a while before the improved version hits the marketplace.

I'm currently in mid-build with the Staudacher S-300D. I'm putting a Saito FA82a 4 stroke in it with JR servos and receiver. I replaced the stock rudder hardware and put in a pull-pull system. This plane is beautifully manufactured and I think it'd be a great choice over the SC. It's a pretty straight forward build and not too expensive. I can't wait to get her in the air.

The Katana 50 is still in the box but I've looked everything over and it looks as nice as the Staudacher.

Generally speaking I think you can't go wrong with CMPro products. They're manufactured nice and very affordable. The SC LG is a design flaw, which they're fixing -- not poor manufacturing. The distributor communicated this directly back to the manufacturer and they were pretty open to the criticism and I believe will fix the problem.

As for the instructions, I have found that they aren't that great for either plane I've built so far and I give them a C+. If you have any building experience at all though you shouldn't have any problem. Just read through carefully.

Good luck.
