More wing related repairs

I encountered two more issues that I needed to address:

  1. The cheap retract servo stripped out.
  2. The rear wing hold down threads stripped out.

I replaced the retract servo with a much higher quality hi-tech metal gear servo and spent about 10 minutes fiddling with end point adjustments and linkage lengths to try to get non-binding operation and minimize the servo buzz.

The stripped rear wing hold down threads was a bigger problem.  I tried to glue a nut to the back to replace the cheap plastic threaded plate, but just made a mess of things, got glue on the …

P-47 Wing Repair

The Hobby-Lobby “Hun Hunter” P-47 seems to have a small design flaw.  Because of the size of the wheel well required for retracting the gear, there is not a lot of foam material along the leading edge of the wing in this area.  At the thinest point, it’s pretty thin. The wing is subject to cracking in this area — starting at the leading edge and proceeding through the middle of the wheel well.  There is a carbon spar in the wing so the wing isn’t in any danger (I don’t think) of coming off in flight, but it does …

Launching Update

Update on MiG-15 Launching Technique

Here is a launch tip for anyone who’s struggled to get the Hobby Lobby MiG-15 airborne reliably:

First, recognize that at FULL throttle, there is a small tendency to want to pitch up (probably due to the large mid-T tail configuration more than thrust lines.

Second, recognize that this is not a prop plane so there is no prop wash flowing over the control surfaces. All control surface effectiveness is due purely to forward speed. During a hand launch, forward speed is at it’s slowest and control surface effectiveness is at it’s lowest.

The problem: …

Hobby Lobby P-47

Introduction

Hobby Lobby recently introduced a neat P-47 warbird model.  It has a 40″ wing span, 4-channel flight control, retractable landing gear, and comes receiver ready.  It includes servos, motor, speed control, and even a suitable battery.  All you have to do is some basic assembly, install your receiver, and you are pretty much ready to go.

Construction

Here are the tail surfaces as they come out of the box.  Everything is pre-hinged.

Here is the fuselage as it comes.  The motor and speed controller are already installed.  Servos and linkages are installed.  Even the cowl comes pre-installed:

Here is …

Hobby-Lobby MiG-15 Electric Ducted Fan Jet

Assembly

My birthday present to myself this year was a MiG-15 electric ducted fan model from hobby-lobby.com.  I bought this at Toledo in April (well paid for it in April … it’s a new item so wasn’t yet in stock.)  It shipped in May and arrived on Tuesday.

Here is a picture as it looks when you first open the box.  I don’t see too many pieces to glue together.

First thing to put together is the tail.  Here are the pieces dry fitted.  The only challenge to assembling the tail is that you are required to free hand …

This is an original release (not the updated version, nor the up-updated version.) I got a great deal on it and I missed my old Sweet Stik so much I had to build another Stik.

December 4, 2012

I have sold this aircraft.  I hadn’t flown it for a couple seasons and my focus has been more on electrics lately anyway.  Hopefully the new owner has many good flights!

Successful maiden flight!

Piper Cub Photo Shoot (Floats)

Photo shoot from my maiden flight off floats.

I finally got organized enough to get my Cub up to my parent’s lake. There is a small thin sheet of ice forming at the middle of the lake so this is most likely my last chance to fly off water this year.

Comments

3 things I need to address: 1. One of the servos is draining the battery *way* too fast. My voltwatch is warning of low voltage long before I burn through the first tank. 2. It is somewhat tail heavy … flyable, but you have to be 100% hands …

Kit built, purchased Spring, 2005. Sold to a fellow club member (I forget the date, but maybe Summer of 2006-ish?)  Yes, it is pink!  That is what I get for buying off of ebay. 🙂

Today we had unseasonably warm weather (high of 61F!) so I shifted around my work schedule so i could fly in the afternoon. I replaced my aging/ailing transmitter battery and needed to test the new one.

The 4* is a lot of fun to fly … quick, nimble, easy inverted flight, tracks really well through …
