Mesaflyer,
I have not personally seen the Nitro Models issue of the P-82. What I liked about my W.M. issue of the kit, was the Alum. Tube that supports the wings three pieces. I know the N.M. model uses plywood braces for wing connections. I've never heard or read of a wing failure on a W.M. F-82. I've read of many W.M. F-82's flying well and no wing failures with this issue of the F-82. I have no idea if the N.P. P-82 construction is good...but the quality of N.P. models are usually ok. I do know that W.M. will sell you parts for your F-82 and have them in stock. I have personally had serious problems getting N.P. to sell me replacement parts...or even give you missing parts out of thier kits they sell you. The prices of the two kits are close...so it's up to you. I do like the color patterns on the N.P. model...but I also know, that W.M. used to sell you a kit of their F-82 uncovered...and it was about $30.00 cheaper. I have no Idea if they will still sell you an uncovered kit...but they may if you call and ask them. I bought my kit from Airborn Models...and I have never had a problem with W.M. I will add though...W.M. parts for their F-82 are not cheap...but they will sell you spare parts (they did sell me parts)...where N.P. will not.
Soft landings Always,
