Another one of Rolf’s builds. This is a SAPAC JAS 39 Gripen, build and modified by Rolf. The model is completely glassed and painted. Decals are from Tailormade Decals. The plane features a 90mm EDF unit and retracts.
Rolf has installed full navigation and landing lights as well as a burner emulation.
Some info on the real plane: The Saab JAS 39 Gripen (English: Griffin) is a lightweight multirole fighter aircraft manufactured by the Swedish aerospace company Saab. Gripen International acts as a prime contracting organization and is responsible for marketing, selling and supporting the Gripen fighter around the world.
The aircraft is in service with the Swedish Air Force, the Czech Air Force, the Hungarian Air Force and the South African Air Force, and has been ordered by the Royal Thai Air Force. A total of 236 Gripens have been ordered as of 2008.
A few pictures of Rolf’s Jet Arrows Mirage 2000B.
The model features Behotec retracts with Jet1A oleo struts, a 90mm carbon fan and a NeuMotors 1512-2.5D, YGE BEC ESC and 6S Lipo.
The model is painted and covered with 2k clear. Decals are from Tailormade.
Current draw is around 90A. The model is capable of taking off from a grass runway and flies like a rocket.
As all of Rolf’s models also the Mirage 2000B features a full lighting system with after burner emulation.
Some info on the full size plane: The Dassault Mirage 2000 is a French multirole, single-engine fourth-generation jet fighter manufactured by Dassault Aviation. It was designed as a lightweight fighter based on the Mirage III in the late 1970s for the French Air Force. The Mirage 2000 evolved into a successful multirole aircraft with several variants developed. The variants include the Mirage 2000N and 2000D strike variants, the improved Mirage 2000-5 and several export variants.Over 600 aircraft were builtand it is in service in nine countries as of 2009.
Just added: A video of the Mirage 2000 in action. Enjoy
Some pictures of our FlyFly Aermacchi MB-339 in Frecce Tricolori colors. For this EDF Jet we have chosen the following setup:
Fan: WeMoTec Midi Fan Pro (90mm)
Motor: HET-RC 600-37-2
ESC: HET-RC 75A
Battery: Hyperion G3 4200mAh 6S 35C
Retracts: Tamjets Mini Air Retracts
With this setup the fan generates around 1.4kW of Power which allows for easy take-offs from concrete and grass fields.
We have further re-enforced the wing with carbon rods to avoid possible wing folding issues. The carbon rod was inserted in a groove cut into the bottom wing from close to air duct till all the way out to the retract mounts. This as strengthened the area between the outer, factory pre-installed carbon re-enforcements and the wing center section.
Some Info on the real plane: The Aermacchi MB-339 is an Italian military trainer and light attack aircraft. It was developed as a replacement for the earlier MB-326.
The MB-339 is of conventional configuration, and shares much of the 326’s airframe. It has a low, un-swept wing with tip tanks and jet intakes in the roots, tricycle undercarriage, and accommodation for the student and instructor in tandem. The most significant revision was a redesign of the forward fuselage to raise the instructor’s seat to allow visibility over and past the student pilot’s head.
The first flight took place on 12 August 1976 and deliveries to the Italian Air Force commenced in 1979.Still in production in 2004 in an enhanced version with a much-modernised cockpit. Over 200 MB-339s have been built, with roughly half of them going to the Italian Air Force.
The Lockheed-Aermacchi MB-339 T-Bird II was a losing contender in the USA’s Joint Primary Aircraft Training System (JPATS) aircraft selection. Among the seven to enter, the Raytheon/Pilatus entry won, which became the T-6 Texan II. According to an article posted on the Italian website ‘Il Porto Franci’, called ‘Armi e finanziamenti nel corno d’Africa’, Eritrea paid about $US 50 million for six MB-339 CEs in 1997. This is the original MB-339 with more advanced avionics for the ground attack role, RWR, uprated Viper 680-43 engine, and larger wingtip tanks. It is capable of carrying Sidewinder AAMs, AGM-65 Maverick AGMs, and laser-guided bombs. Unit price of the MB-339C would have to be somewhere around $US 8.3 million in 1997 dollars.
Just back in stock: The new HET-RC F-86 Sabre Jet in Airbursh Color. The HET Sabre features an epoxy fiberglass fuselage with painted on color scheme. The model can be launched from ground with a retractable landing gear (mounts pre installed) or bungeed. Wing tanks are available as option.
The SM110-45 EDF system is the latest from Stumax Aircraft. It is the same diameter as the SM110-52 (it actually uses the same orange shroud, so swapping between the two is a snap), however that’s where the similarity ends. The SM110-45 was designed for the high speed end of the flight envelope and is intended for R/C pilots who just want ultimate performance. The motor is housed in a precision CNC machined aluminium centrebody which is anodised blue to increase the surface emissivity coefficient, so that it emits (radiates) heat more than 10 times faster than a plain machined aluminium part. This centrebody features semi-circular grooves machined along its length to provide excellent cooling for the Neumotors 15 series motor. These grooves are machined with a curved path close to the stators so that they match the flow around the stator for maximum efficiency and minimum turbulence, unlike other fans which have taken the easy route and machined straight cooling fins. The cooling fin grooves are semi-circular in section so that there is smoother airflow through them, and so there is still adequate aluminium left on the heatsink to absorb thermal transients, or spikes. Attaching to the rear of the centrebody is a lightweight moulded carbon fibre after fairing which also incorporates an airfoiled section through which the motor cables may pass. The dynamically balanced, four bladed, hand laid carbon fibre rotor is designed to maintain a constant power loading on the motor at all airspeeds, and achieves unmatched dynamic efficiency at high airspeeds. It is moulded using tip to tip unidirectional carbon fibre tows, with carbon fibre cloth on the blade exterior. Tip to tip carbon tows ensures the centrifugal loads of the blades transmit stresses through the fibres of one blade, through the hub and onto the opposing blade. This results in a rotor which is incredibly strong, with no chance of throwing a blade, unlike some fans which try to economise on carbon fibre by having a hollow hub with the carbon fibre being forced to bend from the blade into the circular section of the hub. The rear of the rotor hub has a precision machined driver bonded in place, with a tapered bore to match the tapered collet shaft adapter fitted to the motor. This method ensures the rotor is always perfectly aligned to the axis of the shaft. The five stator blades are solid carbon fibre, and are bonded to the aluminium centrebody and shroud with an aerospace grade adhesive.
