Pilot 100CC YAK Fast Build CF Version
Build Review by Rockin' Rick Part 1
The Plane was boxed up at the Pilot-RC factory and sent over by DHL Worldwide express. A layer of Plywood was installed on the outside the cartons to provide extra protection during its trip to me in the US. Thank goodness the plywood layering was added as it provided excellent protection for the model when it arrived. DHL did their absolute best to destroy the cartons and contents but their efforts were thwarted by the excellent packaging job done by the the great folks at Pilot RC. A small chip on the underside of the cowling was sustained but it is in a place that will be cut out to provide cooling for the engine later. I would not recommend DHL to anyone to ship anything after this experience. In my opinion, they are truly the bottom feeders of the shipping industry. I also just recently heard that they are ceasing operations in the US. Good riddance. I've placed the plane in a well padded cradle so let's get started on the build.
After removing and inspecting all the parts it's time to iron down everything and then pull all the fabric down tight with a heat gun. This was very easy to do and I had it finished in no time at all as there were hardly any wrinkles in the fabric straight out of the box. Pilot-RC's QA team is really on the ball with this aircraft.
As always, we'll start on the engine and associated parts working our way from cowling to rudder on the fuse assemblies. The model is supplied with firewall reinforcement already bolted in place. Aluminum angle is employed and bolted to the side rails and firewall using socket head bolts backed up with lock nuts. The firewall is already pre marked for the installation of a DA-100 engine. Nice touch, I like that, and mounting the DA-100 engine will be a snap. 5/16" holes are drilled at the pre-marked locations and 1/4-20 blind nuts are epoxied and pulled into place using an extra 1/4-20 bolt.
The supplied plywood package has several pre cut sheets for installations. We'll be using one of the bottom motor box stiffeners now to provide a base for our throttle servo installation. I like to mount my throttle servo to the bottom of the motor box. Of course, where you mount yours is entirely up to you for what fits your application. I cut two pieces of 1/4 balsa stock and epoxy them to either side to the bottom of the motor box as shown for support. Then, using a piece of 1/16 lite ply, I cut a piece long enough to span across the bottom of the motor box and just a bit larger than the long side of the throttle servo. Trace around the location for the throttle servo, and set these two pieces aside. We'll come back and install them after the canisters are in place.
The cowling is temporarily bolted in place in order that we might determine the standoff distance needed for the engine. A tape measure is inserted through the cowling and butted up on the fire wall to find the exact clearance needed. The exact measurement is 7 1/4 inches to the front of the cowling from the firewall. Then, we measure the distance on the DA-100 engine from the back of the engine mount to the front of the propeller hub. That distance is 6 1/2 inches. An extra protrusion of the prop hub is great for YAK's so we'll add 1 1/4" of stand-offs to make the distance to the propeller hub 7 3/4 inches from the firewall, thus clearing the cowling by 1/2". This is Normal for all Yak’s and may be required to achieve proper C.G. location and engine performance. More stand-offs can be added later if balancing becomes and issue and you need to adjust the weight up front. I've seen YAK's with the prop hub protruding as much as 1 1/4inches past the cowling and still flying great. This is really going good so lets get on to the next page.
Editors note: We had hoped to try out the DL-100 engine for this plane, but Bob at DL USA said they didn't have the resources for sponsorship at this time. Oh well, DA is still the gold standard in my book, and I'll take it in that direction again this time. You might pay less, but you won't find better quality and service than DA. Stay tuned, more to come.

HI
everyone! Man, I've been looking forward to the arrival of this one.
This is one of the best kept secrets in the RC airplane world at this time.
Not too many folks are aware that this plane is becoming available and I managed to
get one ordered early from the distributor. It is possibly the best
built YAK out there and I'm sure that you'll agree when you see just how
this one is constructed. I've heard that Aeroworks is shakin' all over
with worry now that someone is able to give them some real competition.
And it just may be a better airplane. All carbon fiber accessories, normally
an option with other planes, are standard on this one. CF Wingtube, CF
Stab tube, CF
landing gear, CF tail wheel, and CF Spinner, are all STANDARD and
included with the ARF. Shoot, it don't get no better than this
when it comes to saving weight. Plus, and don't forget this, it's
already pre-hinged for you, and the gas tank and fuel dot are installed
ready to go in the plane. What's more, it's canister ready!!!! A
super hardware package, second to none, is also included. No cheezy
cheap kid stuff here made for a tinker-toy. And the price? Wait
till you see it. Email me if you want to get more information about
the plane because I know who will be
the least expensive US distributor so you can get your hands on one of these beauty's
at a reduced cost. You
can get your pre order in now and save some bucks. I've heard that the prices
will go up after the big shipment arrives. Man oh Man, I can't wait to
get this hummer in the air so lets get to the build.
