I thought I would challenge myself having graduated to electric 60cc size models buy doing the same with a100cc airframe. I fully appreciate this is very much a "Marmite" subject going by some of the USA forums. Some modellers like 'em that size, other think it's step too far. Well we will see therefore I am doing it on a tight budget in case I fall flat on my face. face 21

I chose Glen's Models 35% Extra 330SC (he does a 35% Cap too)for this purpose. Let me say I liked Glen's relaxed way of business and service.

Let's take a walk round the kit first.**LINK**

First the airframe is, well lets say, well engineered although there are few fixings/fittings supplied this is reflected in the competitive price. Models of a similar size are probably twice the price I paid, but I will use this cost difference up on adding more lipos to my collection.

First I had to get my head round the access point underneath the fuselage rather than the more conventional topside meaning all my work will be inverted. First picture is the hatch.

The cowl has a nice finish and is secured at seven points with bolts.

excuse the sideway pictures, but there are upright in the album!

Here is hatch area - not a huge amount of room I must say.

The working surfaces like the rudder are shrouded and fixed using a rod.

The main wings and tail feathers are of a good quality finish and the working surface fixings are also shrouded and fitted the same as the rudder.p1050878.jpg

All wings come will foil protective bags which is a nice touch.

Looking at the other bit next.

p1050868.jpg

The tail wheel assembly looks well up to the job.

p1050869.jpg

As do the spats and collars. There are no wheels or axles supplied so these will have to be bought.

The undercarriage is a nice silver metal job although a bit of extra weight there.

Next the the motor box. This comes as a set of parts which assembly is required and I think a bit of reinforcement will be required give the size of the lump of metal to be put on the end.

p1050867.jpg

I decided to dry fit the parts with the motor wall in place. The predrilled holes are not quite the same as the bolts pillars on the motor by about 2-3mm so another job there. Side thrust is built in however.

The motor I chose is a Turnigy CA 120 from HobbyKing which by the ways has no manual at all!

**LINK**

However, the reviews are mostly good and I have found an example of one used in a build.

I decided to solder the connectors on it straight away. Nice hot iron needed here!

I would have bought the recommended Fat Boy OPTO ESC from HobbyKing too, but for the fact that most critics say the allied programming card doesn't work.

So I plumped for this.

p1050758.jpg

p1050766.jpgThe programming takes place via the supplied lead attached to the unit.

p1050760.jpg

The programming unit does work as I have tried it, but it must be connected in a particular order (guess how I found out!)

The other end connectors were soldered to the OPTO ESC.

Hopefully, I will start the build in earnest next week - so if you are interested watch this space!

wink 2 Gotcha, John.

I have to buy turnbuckle push rods, couplers, axles, and a couple of extra servos. I have wheels and most nuts and bolts in stock ....... hopefully.

Adrian.

I have a Glenns Cap fitted with a Zenoah 62 and access to the wing bolts is via a hatch on the underside of the model. It's the one thing about the model I really don't like and I only need access once per day to fit the wings and once to remove them.

If I needed to turn the (rather large) model upside down to fit / remove batteries before each flight I think it would do my head in.

If I were you, I'd get my thinking cap on and come up with a way of fitting the batteries in from the top. Maybe by adapting the canopy to make it removable? You might also be able to fit the wing bolts via the same top access.

I dunno, if it just tips onto its nose, should be fine, no fuel to leak.

Good point. I can't tip mine onto it's nose for the very reason you gave.

I'd still try to put a hatch in the top though if I were building another - even a petrol one, but especially an electric one.

I know what mean, Gary. Until I start to think about where thing go in the fuselage I can't say what's to be done. A lot depends where I need to put things to get the CoG right.

As far as changing batteries, I have a ground level cradle which I can use by tipping the plane backwards onto it. Not ideal as you say, but I will know better what to do near the finish of the build.

One shot I forgot was of the rudder with attachment tube.

Against all logic I fitted the U/C legs mainly because I like to have the fuselage stand on something. It is fitted with M5 bolts which were not provided so i dug out some 25mm hex bolts and fitted these with blue threadlock.

The bolt holes only allow you to fit the U/C legs one way which is helpful. There is quite a cant angle on them - don't know how scale this is.
