GB Models Gernot Bruckmann Yak 55M EPP Fixed Wing - RCM&E Oct.2010 Review Model
This model has been subject to a product review in RCM&E October 2010 edition. Mike William concluded that this was the ‘best outdoor foamie that I’ve yet had the pleasure of flying’.
If you could only select one aircraft to own I fly and would suggest that the Gernot Bruckmann GB Models YAK 55M is on the very top of the list. This aircraft is so versatile you will wonder how you ever survived not owning one. It may not be as attractive as some of the recent moulded foamies appearing in the market, but if you want a model that will actually fly the pants of these pretenders the GB Yak is the one. From hardcore 3D to pattern the Yak 55M can do it all, and if the worst happens it just bounces. Tough genuine EPP and carbon reinforcement provides outstanding durability. It takes some serious attempts to write off a GB Yak although we’re not encouraging you to try but to give you the assurance that this model is tough. As your confidence grows, and it will with this airframe you will fly it in all weathers and find every opportunity to have a quick flight. We would go as far as saying this is possibly going to be the best value aircraft in your fleet because it will be flown so much. The wonderful thing about the Yak 55M is the power and servo requirements – probably items you already have stuck in a draw from a model that didn’t fly as well as this one will. Got an E-flite Park 480 or something similar in the 250 - 350 Watt category? If you have it will be ideal. Worried about buying more Li-Po’s? Don’t be. The Yak has been designed around the most popular Li-Po battery size the 3S 2200mAh. Requirements don’t come more mainstream than this. If you don’t have the necessary equipment we offer great tried and tested power sets that are moderately priced and will get your Yak in the air fast.
The GB Models Yak 55M series is available in Gernots trademark yellow/red/black trim scheme. Please note that the instructions manual is a step by step pictorial guide with the text supplied in German.
Required radio and servo type:
A minimum of a 4 channel radio, preferably at least 5 channel with mixing ability for aileron differential or flaperon. We would highly recommend that a 2.4GHz radio is utilised for effective interference rejection.
4-5 channel receiver. If using a four channel receiver a Y-lead will be required.
4 x TowerPro MG90 servos or similar
2 x 250mm servo extension leads for ailerons
2 x 300mm for elevator and rudder. The lengths required may vary depending on the servo type.
Please note that subsequent to Mike Williams submitting his article the EMAX servos he recommends have burnt out. Unfortunately this is not an isolated occurrence and other customers who selected this servo for this model have had similar problems. There is nothing wrong with these servos in normal operation but we have to conclude that the Yak is probably beyond their capabilities especially in a hard flown example. We therefore would recommend that only the larger servo type i.e. TowerPro MG90/HS65MG be fitted. This size of servo is relatively unstressed in this environment and feature larger gear teeth that are more resilient to stripping.
When Mike purchased his second model – yes he did purchase the original review model – he elected the MG90 servos.
ParkAero Telink SU29/Yak55 Ido Segev power set-up for 3S operation:
Brushless motor: DYS/Telink 2217
Propeller: APC 10 x 4.7sf / 11 x 3.8sf
Brushless speed controller: Sunrise 40A SBEC
Battery: 1550 - 2200mAh 3S 25C 11.1V Li-Po
This is basically the best set-up for controlled 3D and will fly the model as the designer intended. The Yak was designed for a 2200mAh Li-Po although a lighter lower capacity pack could be used. The lighter arrangement is proving popular as the lighter pack provides a ‘floatier’ flying style.
