In one of the posts further down I recommended that Jonathan Dawes got a Hallam Combat Wing.

Vernon Levy replied that his friend had two identical models but one was sluggish whilst the other almost uncontrollable.

I have two of these and have noticed that if you glow the boom on as supplied the tail will have positive or negative incidence - a few degrees.

Could this be the explanation for the above problems?

Hi Tony,
I don't quite follow you. Do you mean that as the stab moves up, its leading edge moves down? I've no idea what effect that would have, but it might *increase* the turn speed, or it might stall.

What is the consencus on the Hallam kits? I'm just about ready to order one, and I'm wondering what the quality etc is like.

I might not get a Hallam wing, as I'm possibly going to scale up the Minilord plans I have to a suitable size.

I don't quite get what you're on about either.

The wing, tail and motor thrustline on a model should all be at zero incidence to perform correctly.

If you just stick the tail and engine pod on the Hallam Combat wing chances are that they are not at zero incidence which will cause trim problems.

Hallam kits are 'good value for money' - are pretty basic - but come with all the necessary hardware.

The ribs are bandsawed out.

I have one of the combat wings nearly ready for covering.

I have not built this wing before, but there is no hidden secrets on any of this. Just make sure that all measurments are equal and that all are squared up and at 0 incidence and you may have to trim with nose or tailweight or as I do it with the boom legnth. Is there a website for these wings? BAD ANDY

there is no web site as yet for Hallam Models. I just might do one for them as a favour

The Hallam range of kits are basic no frills C/L models made by Bob Meager a disable modeller who has lost most of the functionality of one arm. Using a series of jigs, bob cits a range of kits using a bandsaw.

All of the models reviewed so far in the modelling press are positive about the flyability of the models yet personal experience of the combat wing as been mixed. One model was wild and uncontrollable, tamed by adding a church roof's worth of lead at the front end and the other was 'sluggish' to the extreme leading to very open loops and a lack of line tension.

I did not build either of these models. One (the wild one) was built by a 58 yeaer old returning to the hobby after a 35+ year gap. The sluggish one was built as a third or fourth model by another modeller with a 30+ year gap in modelling activities.

As I only encounter these models at the flying field I can not vouchsafe their alignment properties regarding egine wing and tail incidences.

On the other hand, the Hallam Peacekeeper (an Aldrich Peacemaker clone) flies on rails will do the book and is robust enough to cope with inverted landings.

I have recenty completed one of the Hallam mini combat wings covered in mylar and powered by a PAW .055 diesel. I took it for its inaugural flight last weekend when it was blowy enough to fly parafoil kites and despite its lightness it flew with enough tension on 40' lines to cope with inside and outside loops though the overheads were a bit flaky due to wind strength. I used a simple jig to ensure that the engine/wing/tail incedences were all at zero. Apart from waiting for an overnight cure for the epoxied engine bearers I finished the kit in under four hours.

Here's a picture:

From personal experience therefore, I can recommend the Peakekeeper for a .15 diesel or glow engine and the minicombat wing for a .055 - .06 diesel or glow engine.

The kits are incredibly good value as they contain all of the hardware execept the tank. The purchaser just needs to buy glue, covering material and an engine.

Vernon..can you get a mail address for Hallam models..I'm ready
to build and fly .05cc combat..I've two of the Paw's(.05cc)
and frankly I'm very impressed with their performance...right
in there with Cox reed valve .049's...I don't know if Hallam
Models is willing to do international shipping....I guess I
should ask; How much wing area does it have?...140-170 sq" is
prefered (by me)..the photo is inspiring..is that a .055cc
mounted on the model?(it doesn't look like mine..) Thanks..

I am sure that they do. When I was talking to Bob Meager the owner at the UK Nats he mentioned that he supplied models overseas.

I have a 0.8cc engine in mine. The wing area is about 137 sq.in. close enough to 140. I covered mine with laminating film. Dirt cheap I scrounged mine from the reprographics office at work. It's self adhesive (activated by a hot iron) and shrinks evenly.

Thanks Vernon......137sq" is fine for the .55cc Paw
I have a PAW .8cc sbr. in a Ringmaster Jr.(195sq")..it flies
great on 45'x.008" lines...I'll send a letter to Hallam Models
soon..... Tony

RE: Re: Hallam Combat Wings#8 source
Here are some prices for the HAllam Kits:

Peacekeeper (Peacemaker clone) £23.50
Mylar Covered combat wing like the one in my previous posting £9 -£10 price to be fixed.
Combat wing suitable for 0.15 diesels or equivalent £14
Flat sheet wing profile coupled flap/elevator stunter for 0.15 engines £18

Shipping is extra and Bob Meager is dying to hear from all US and world wide modellers wanting to purchase kits.
