H9 33% Pawnee Tug Conversion

Hello all, new to this forum. I am about to purchase a Hngr 9 Pawnee, but it does not have a tow mechanism. Where would I purchase one?

You need something like this. http://www.icare-icarus.com/Remote-t...ne_p_1230.html

Need to add a bulkhead and use a decent metal gear servo.

Here's a link to the thread on how I installed releases on both of my Pawnees.

I have just acquired a Pawnee, the upper L/G support bolts bent and I have replaced them with 5mm bolts and added 3/16 ply reinforcement to the box. The tires crumbled and I have added new wheels. My problem is "slack" in the support tubes where the springs fit. I can lift up the L/G about half an inch before the spring come into action. Does anyone know the size of replacement springs from McMasters? I can make a video if this is not clear

My tired old Pawnee (I'm the 3rd owner) lost the right door the other day. Almost finished fabricating a new slightly more reinforced replacement but was wondering if I should duplicate the stock locking mechanism or is there a better solution? I plan on taping both doors in the future. At least the leading edges.

[Sinkhappens86]

The only issue I've had with the stock latch is the hole in the fuse enlarging from vibration. Stock latch plus taping seems to work fine. It's usually the wood at the bottom that fails. But looks like you've reinforced that nicely.

Sounds good. Will just go with duplicating the stock mechanism and tape.

If I had a dine for everyone of those doors people have lost........... well, Id probably have a couple buck, but regardless I've heard that happens a lot. anything you can do to make it better is good, tape it for sure.
