Very fast, very aerobatic. I need to reduce aileorn and elevator high rates.

Coming to pages near you one day.

Peter....I love your designs..but....could you please design them with removable cowls, so that those of us of a lowlife electric persuasion could do an easy conversion...Lol!!smile p

Kindest Regards

Andrew

I design them so I can get at the engine.

There is a very simple way to make a removeable cowl. Make the cowl as shown but complete without cut outs.

Put a facing of 1/16" ply on the rear face. Make small grooves in about three places and screw the cowl to F-1 with old servo screws.

You could even make keyhole slots and just slot the cowl over the over the screw heads

Nice one .When will people realise that you just love proper engines? By the way,not like you not to have the engine mounted at 45 degrees is it ?

Thanks Myron.

No, the engine mounting is a new idea. Came from my scale Stits where I wanted the engine to replicate the original flat 4.

On narrow fuselages it is quite easy to do and looks so much neater.

Here's another way to do an electric installation Andrew.

dsc09672 (custom).jpg

dsc09674 (custom).jpg

Removing the 4 screws that hold the motor to the X mount means the motor can be removed through the hole at the front.

Another nice design by the way Peter.

WOW Peter, your design and build output is just phenomenal!! How many designs have you created?

Just out of interest, have you ever designed a model that proved too difficult to fly....sadcheeky

Oodalally is from Robin Hood. an exlamation that can be excited, happy or dismayed. Very appropriate for modellers.

About 150 published designs. I haven't a clue how many in total..

My recent Stits Junior was flyable but only just. it crashed on take off twice out of six take offs. Once in the air it wasn't bad.

A couple of others which failed due to a wrongly located CG. Needless to say not published.

Got a drawing for a TD 049 powered glider to finish off now....

Well, I can certainly say that it flies right. IT is very close to Minnow but low wing and one or two other very slight changes to moments and wing section. so I knew it would be pretty good before I even flew it.

I know that Peter really prefers IC powered models however there is a growing trend towards electric especially amongst newer recruits. Therefore it would be nice if some of the free pull out plans showed a revised front end for electric power too. In this case I suppose the engine bulkhead would be needed further forward as the motor is shorter and space is needed behind for the Lipo. It wouldn't take much extra space on the drawing to show this option together with a top hatch for Lipo access. It is so much easier to build exactly to the plan rather than modify it yourself if you are a newcomer.

Frankly we need to do everything to help & encourage the new recruits to build their own models and if this means giving details of electric conversions ..... Otherwise they wont buy magazines but buy ARTF from the websites.......

Some of us don't know what size the electric motor would be, or the batteries so it would be very hard, if not impossible to draw up an alternative front end and be sure that it is right.

I suppose I could draw it up for a Speed 600 and a 7 cell Nicad but I don't think that would work to well on a model intended for a .32 ic engine.
